First Record Of The California Yellow-legged Frog In Park
By W. S. Vincent, Ranger-Naturalist
A small frog which proved to be Rana boylii boylii was
collected by the writer in the pond of a small spring on Red Blanket
Creek on July 2 while on a field trip with the Park Naturalist George C.
Ruhle.
This frog has not been reported previously in any literature as
having been collected within the park boundaries. Its range has been
reported as being the middle Rogue River valley (vicinity of Medford)
and in the area around Lake-of-the-Woods. It has further been reported
to the north in Marion, Lane, and Linn counties. This specimen would
appear to consolidate these ranges. No further collecting in the area
was possible to extend the range within the park.
A brief description of the frog is as follows*: "Light grayish,
greenish or brownish back, indistinctly mottled; under parts white to
pale yellow on posterior parts and underside of legs; throat and sides
of body mottled with dark color; three inches or less in head-body
length."

Early Spring Flowers At Crater Lake National Park
By Dr. Ruth E. Hopson, Instructor, Field School of Nature Appreciation
As the weather grows steadily warmer in early June and the days of
sunshine begin to out-number those of storm, the snow banks slowly
dwindle in the park. In the damp, brown, bare spots that appear under
the outer branches of the mountain hemlock trees and in the open spaces
beyond, the pale yellow-green spears of smooth woodrush (Luzula
glabrata) replace the snow. The leaves, even before they have
obtained their full quota of chlorophyll, separate to expose a
flat-topped cluster of tiny flower buds. Sometimes several of these
grass-like plants may be found about the thinning edges of the
snowbanks, each plant in a circular pit of its own making. A typical
display contains all stages of development from spears appearing above
the ground that is still wet from the recent snowbanks to fully
developed plants with their green ribbon-like leaves and their feathery
brown inflorescences. To one familiar with the forests of mountain
hemlock of the Hudsonian Zone and with the succession of plants that is
found there during the short growing season, the smooth woodrush is the
herald of coming summer, the promise of the gorgeous display of mountain
flowers that is to follow in the meadows close by.
Where the heavy snows of winter have recently lain, such plants as
creeping Crater Lake currant (Ribes erythrocarpum) and trailing
raspberry (Rubus lasiococcus) are pressed into the soil. Soon
the warmth of the sun is reflected in the growing energy that enables
the twigs and leaves to lift themselves from the ground to their summer
position. Inconspicuous racems of small saucer-shaped bronze flowers
are present almost by the time the leaves are freely exposed to the air.
The white strawberry-like flowers of the trailing raspberry require more
time to develop.
The yellow faces of the smooth woodland violet (Viola
glabella) reflect the bright light upon the mountain hemlock trees.
This violet is one of the earliest flowers to bloom. In the forests
along the coast and in the valleys of Oregon, the smooth woodland violet
blooms in February or March, at Crater Lake in June or July.
Edging groves of hemlocks, especially on the back slopes of
Applegate and Sun valley, the lamb's tongue, or glacier lily,
(Erythronium grandiflorum) var. pallidum) nod their yellow
heads as snow banks dwindle beside them. Steep rocky hillsides that
have south or southwestern exposures are among the earliest places to be
free of snow. Here rock-loving perennial plants are waiting to take
advantage of the early moisture to enable them to display their flowers
and mature their fruits. The western wind flower (Anemone
occidentalis) is one of these plants. While the leaves are still
tightly folded along the midrib of each linear segment the translucent
white sepals, purple tinged without, form a cup of delicate beauty on
top of each thickened stem. Later in the summer after the stems have
grown tall, heads of plumose achenes (one-seeded fruits) will have
replaced the white cup-like flowers. Backlighted by the sun, each head
then appears with its own hair. One of the most beautiful sights of the
high mountains may be had by looking toward the sun across a hillside or
meadow of western wind flowers when their pale green fluffy heads are
fully matured. Near the summit of Garfield Peak, a smaller anemone with
pale blue flowers, Drummond's windflower (A. drummondii), is
found. The achenes of this species are densely covered with cotton.
Heads of the achenes of Drummond's windflower are therefore much less
showy than those of the western windflower.
Exposed rocky cliffs such as those of the Garfield Trail are clear
of snow early. Here crevices afford footing for several species of
rock-loving plants. Three species of plants that bloom among the first
are usually found elsewhere in the Cascades only above timberline in the
Arctic-Alpine Zone. The flowers of the mountain sorrel (Oxyria
digyna) are inconspicuous, but the color scheme of red and green and
the pattern of circles and straight lines formed by the kidney shaped
leaves and the straight racemes of tiny flowers make this plant easy to
recognize. The slender polemonium or Jacob's ladder (Polemonium
shastense) is a delicate study in pastels. The large clusters of
pale blue and yellow flowers often just balance the soft green mass that
is made up of long pinnately compound leaves. A lone plant of
feather-leaved fleabane (Erigeron compositus), with its finely
divided leaves, grows from a soil pocket in the cliff about half way up
Garfield Trail. By the time the slender polemonium is in profuse bloom,
the fleabane is just lengthening the strap flowers of its single
flowerhead.
Two crucifers bloom early along the trail. Members of the
Cruciferae or mustard family are marked by having four petals and
six stamens, two of them shorter than the other four. The dagger-pod
(Parrya cheiranthoidea) is recognized by its long narrow gray
basal leaves and its deep purple flowers. The pods of this species
indicate clearly the reason for the name, dagger-pod. A small species
of rockcress (Arabis holboellii var. secunda) is found
scattered among the rocks. Each flower and later each elongating pod is
turned to one side of the extended flower stalk.
Before its leaves have unfolded, bleeding heart (Dicentra
formosa) is in bloom. The flowers are typical of the species but
the leaves are coarser and less finely divided than is usual for this
species of lower elevations.
Bright patches of yellow and green among the rocks are apt to be
fringed-leaved cinquefoil (Potentilla flabellifolia). The
flowers that resemble buttercups and the leaves that look like fringed
"three-leaved clovers" signify this species.
A number of shrubs bloom in the Garfield rock gardens while snow is
yet deep on the slopes below. Two species of bushy currants are found
side by side in some places. Both develop racemes of creamy-white
tubular flowers at about the same time. The waxy currant (Ribes
cereum) has small smooth leaves. The gummy currant (Ribes
viscosissimum) has larger sticky leaves. Although the service berry
(Amelanchier florida) is dwarfed along the Garfield Trail its
blossoms of white strap-shaped petals almost cover the bushes. The
leaves of the service berry are easy to recognize because they are oval
to almost round and notched about half the margin that is away from the
twig.
Large areas of the open rocky slopes are carpeted by two creeping
shrubs that produce their flowers while snowbanks remain closeby. The
rigid, brick-red branches, conspicuous among the glossy, leathery
evergreen leaves and the racemes of dainty bell-like pale pink flowers
make the pinemat manzanita (Arctostaphylos nevadensis) an
attractive ground cover. The lovely pattern produced by the small,
holly-like, deep green, shiny leaves and the puffs of tiny lavender
flowers of the squaw carpet (Ceanothus prostratus) is equally
attractive.
The damp soil of the mountain meadows at first appears almost
destitute of life. Here and there the clumps of brilliant red growing
tips of Newberry's knotweed (Polygonium newberryi) push above the
uniformly brown surface of the ground. This plant is least attractive
during its flowering season. The tiny, papery white flowers that
cluster in the axils of the leaves are so inconspicuous that a person
looking directly at the plant in full bloom often asks what the flowers
are like. Nevertheless, each delicate flower proves to be a delightful
surprise to one who chances to examine one with the aid of a hand lens.
Following the blooming period, glory returns to the knotweed as its
dying leaves turn scarlet. If one chances to view these leaves against
the sun they appear translucent like stained glass windows. But this is
a picture of late August, not early June.
Among the patches of red tips of growing Newberry's knotweed,
steer's head, (Dicentra uniflora) is an attractive surprise to
anyone who discovers it. The single rose-colored flower, held at an
angle barely clearing the ground, suggests a tiny steer's head even to
many who do not know its name. Each flower is surrounded by two or
three finely divided gray-green triangular leaves that lie flat on the
ground.
Spring beauties (Claytonia lanceolata) are the most abundant
flowers on the open slopes. As they push through the earth, the two
lance-shaped leaves are held tightly together, like hands over their
heads. Soon they separate and are lowered to their characteristic
position opposite buds. As the buds open one at a time, the peduncle
straightens and holds up the flower that looks like a deep saucer of
delicate pink-striped china.
The rosettes formed by the deep-green spatulate leaves of pussypaws
(Spragus umbellata) are at first small and tight against the
ground. The first dense cluster of tiny flowers are greenish. As the
season progresses, the clusters become more fluffy and the flowers turn
white, then red, all the while the rosettes of leaves are increasing in
size.
A small yellow violet (Viola venosa) with gray-green leaves
is so inconspicuous that it is easily overlooked. Close examination,
however shows it to be an unusual violet that often makes the most of
complementary colors, since the back of the upper petals may be purple
and the other petals are purple-violet.
The rainbow colors of the spider-web paintbrush (Castilleja
arachnoides) blend perfectly into the pumice slopes. The paintbrush
tips enlarge as the flowers bloom farther and farther down the stem.
This plant is covered by a fine cobwebby pubescence that adds a
delightfully soft texture to its delicate coloring.
Dense, cottony plots of alpine antennaria (Antennaria media)
look like irregular sections of a patchwork quilt on these mountain
meadows. Tiny stems with reduced leaves and clusters of papery white
flower heads rise a few inches from each basal clump of leaves. Other
plants that may be found in bloom in the mountain meadows during the
early summer are: varied-leaved phacelia (Phacelia heterphylla),
alpine agoseris (Agoseris alpestris), blue stickseed (Hackelia
jessicae), and several species of sedges (Carex sp.).
Three shrubs that are common about the springs or along streams
begin to flower while patches of snow still remain; the catkins appear
on the Eastwood willow (Salix eastwoodae), the deep rose of the
flower buds make spots of color on the mountain spiraea (Spiraea
densiflora), and the yellow twin-flowers blend with the yellow-green
leaves of the black twinberry (Lonicera involucrata). In soggy
reaches along the streams and about the springs, the ground is often
covered with the tiny Gormon's buttercup (Ranunculus gormandii).
Taller plants soon extend their flowering racemes above the mat of
mosses and buttercups. The elephant's heads, (Pedicularis
groenlandicum) make conspicuous patches of rose color, as do the
alpine shooting stars (Dodecatheon alpinum). The slender stalks
of the green and white bog orchids (Habernaria stricta and H.
dilatata) with their sweet-scented exquisite flowers add much to the
beauty of the scene. At this time a few white flowers are peeking out
of the flat terminal flower clusters of the northern valerian
(Valeriana sitchensis), and the white flowers in the dense,
slender heads of the bistort (Polygonum bistortoides) are also in
evidence.
By the time the snows are gone, most of these flowers have already
produced their first fruits. Many of them have a system of flowering
that enables them to keep producing flowers farther up the stem as long
as the moisture and temperature conditions are favorable, thus a long
season results in abundance of seed, yet a short season permits maturity
of a few fruits at least. The early spring scene shifts rapidly, so a
markedly different one greets the visitors during July and August. Some
year come early, see the early spring flowers!
