FOREWORD 


ILD FLOWERS were a joy and inspiration in the happy days of child- 
hood when I was taught to observe and sketch them under the direc- 
tion of a skilled artist. Years passed before a botanical friend at Glacier, 
British Columbia, asked me to portray a rare and perishable alpine flower 
so as to preserve its beauty, color, and graceful outline as a living thing. 
During succeeding seasons I painted other rare specimens until many of the 
‘living flowers that skirt the eternal frost’’ in the wildflower gardens of the 
Canadian Rockies were transferred in color and form to the East, where 
sketches of the native woodland and meadow blossoms soon began to join 
them. 

During the past ten years I have spent from three to four months each 
season in the Canadian Rockies, where Dr.Walcott was carrying on geolog- 
ical explorations, covering in all more than five thousand miles on the 
mountain trails. This afforded me a wonderful opportunity for intimate 
study of the flora, my aim being to collect and paint the finest specimens 
obtainable, and to depict the natural grace and beauty of the plant without 
conventional design. Many of the western sketches were made under trying 
conditions. Often, on a mountain side or high pass, a fire was necessary to 
warm stiffened fingers and body. In camp, the diffused light of the white 
tent was a great handicap, and considerable ingenuity was required to obtain 
a proper combination of light and shade. The paint box and pads found 
safe conveyance on the back of the saddle, except in unusual storms of 
rain or snow, and many times while waiting for the pack train to be made 
ready, a sketch was begun or completed. The short lives of the blooming 
plants definitely limit the number of sketches that can be made during a 
single field season, for many hours of work are necessary to finish a single 
sketch, and wild flowers wither quickly. A sharp frost in July or early 
August will ruin them, or an unusually warm, dry season or a cold, wet one 
will prevent flowering or kill the blossoms that have matured. For these 
reasons desirable specimens of many of the fragile alpine flowers are difficult 
to secure, and in some instances were seen in perfection but two or three 


times during the many seasons on the trail. The limited habitat of others 
made it necessary to take long rides and climb high above the timber line 
to procure them, and frequently no trails were available. Our sure-footed 
mountain ponies were a large factor in our success. 

Both the bloom and the fruit of a few trees have been sketched with the 
hope that these exquisite forms may be more observed and appreciated by 
nature lovers. The illustrations of eastern plants have been made from 
specimens collected as opportunity offered and from those contributed by 
many friends. All the sketches are life size. 

As time went on and the collection grew, botanists, artists, and others in- 
terested in flowers began to urge that the water-color sketches should be per- 
manently preserved and made available for students and lovers of the beau- 
tiful in Nature, before the dust of time faded and browned them to the hues 
of the pressed flowers of the herbaria. A survey of wild flower publications 
led to the decision that there was need for a finely illustrated work that 
would be of service pictorially to all professional and amateur botanists and 
designers, and to the larger group of lovers of wild flowers and the great 
out-of-doors. To many of these the living flowers are inaccessible, and their 
real beauty is unknown. No attempt has been made to create a text book 
with technical descriptions, or to illustrate all native American wild flowers, 
and only native plants have been included. 

The preparation of the work has been a labor of love and has been made 
possible by the sympathetic interest and inspiration of Dr. Walcott, who 
has been unfailing in his help and encouragement. 

My sincere thanks are due to Dr. Frederick V. Coville, Dr. Edgar T. 
Wherry, Mr. PaulC. Standley, and Dr. Paul Bartsch, who haveall given freely 
of their time and knowledge.

MOUNTAIN LADYSLIPPER 


Cypripedium montanum Douglas 


One lovely morning in early summer we left camp near Radium 
Hot Springs in the Columbia River Valley in British Columbia, our 
two saddle horses harnessed to the buckboatd, the saddles securely tied 
behind the seat. After a drive of seven miles the horses were saddled, 
and we followed a disused trail four or five miles back into the range 
on the eastern side of the valley. There were many flowers, the dense 
growth of trees and shrubs keeping out the hot tays of the sun and 
conserving the moisture. Just as we turned across a partially shaded 
flat on the side of the little canyon we had been traversing, a won- 
derful sight burst upon us. Scattered among the low-growing bushes 
were great clumps of this splendid orchid in the perfection of bloom. 
A beautiful plant about eighteen inches tall, with a delicate perfume 
quite its own—no wonder that we quickly dismounted to pay hom- 
age to this queen of the forest. 

Never before had we seen such a flower, and no book upon the 
plants of the Canadian Rockies mentioned its occurrence there. A 
bunch cartied to camp survived many days, long after the sketch 
was completed. 7 

The mountain ladyslipper is frequently found in the mountains of 
California, and northward along the coast as far as Vancouver, and 
northeastward along the Rocky Mountains to Saskatchewan. 


PLATE I 


PUSSY-EARS 


Calochortus elegans Lindley 


We were following the old stage road, now replaced by a new 
motor road, in the Columbia River Valley, twenty miles south of Canal 
Flats, at an altitude of 2,500 feet. The marvelous larches and pines of 
the primeval forest towered above us, and over the grassy forest floor 
were scattered many flowers with which we wete familiar. Suddenly 
we saw the grass dotted with a white lily, which was unknown to 
us, and upon examination we quickly comprehended the reason for its 
common name of “pussy-eats,” which our companion gave it. So 
graceful was it that we could only wonder that a flower so beautiful 
had not been enticed long ago to grow in our cultivated gardens. 

Pussy-eats ranges from Utah and California to British Columbia 
and Montana. 


PLATE 2 


FALSE LOCOW EED 


Oxytropis gracilis (Nelson) Jones 


This plant must not be confused with its relative, the true loco- 
weed, that is so destructive to animals on the plains of the southwest- 
ern United States; it seemed entirely harmless to our horses, who ate it 
freely. In full sunshine its pale yellow or straw-colored flowers, borne 
on stems six or eight inches tall, are wonderfully attractive against 
their setting of sage-colored foliage. In limestone regions, where 
moisture is limited, the blossoms develop well only if an abundance of 
water is available at flowering time. 

False locoweed is a member of the Pea Family. It ranges from 
Idaho to South Dakota and northward into Alberta, Canada. 

The specimen sketched was obtained near Ghost River on the 
eastern slope of the Rocky Mountains, twenty-five miles from Banff, 
Alberta, at an altitude of 3,500 feet. 


PLATE 3 


NODDING LADIES-TRESSES 
Ibidium cernuum (Linnaeus) House 
SLENDER LADIES-TRESSES 


Ibidium gracile Bigelow) House 


These two fall-blooming members of the Orchid Family are 
frequently found growing in the gtass of old pastures. Nodding 
ladies-tresses usually chooses a wet situation, but the slender one 
is more likely to be found in drier places. Both are inconspicuous 
in their chosen habitats, for their leaves and stalks are so gtasslike 
that they seem a part of the general herbage. The genus name has 
arisen from the fancied resemblance of the anther to the head of 
an. ibis. 

Many botanists prefer to use the genus name Spiranthes, which 
means spital-flower, but [bzdzum has prtiotity. 

Slender ladies-tresses is notable for its green-centered lip, and for 
the fact that its leaves, which are evergreen, wither away before 
flowering time, the flower stallx bearing only inconspicuous bracts. 

These two orchids have a similar range, occurring from Florida 
northward and westward, extending into southernmost Canada. 

The specimens sketched were found near Mount Kisco, New York. 


PLATE 4 


PINK FUMEROOT 


Capnoides sempervirens (Linnaeus) Borkhausen 


Pink fumeroot is a dainty wild beauty that loves rich rocky woods, 
whete it grows in perfection. The leaves are a delicate shade of green, 
and the pale pink flowers, with a yellow lip, poised on slender stems, 
sway gently in the wind. The plant is a relative of the bleeding-heart 
of our gardens, and of the European fumitory. Like the latter, its 
roots exhale an intense nitrous odor, and the common name fume- 
toot refers to this characteristic feature. 

Pink fumeroot has a wide range, from North Carolina to Nova 
Scotia and westward to British Columbia and Alaska. 

We found it in the valley of the Kootenai River near the motor 
toad between Banff and the Columbia River Valley, at an altitude of 
4,000 feet. 


PLATE § 


SUN-DIAL LUPINE 


Lupinus perennis Linnaeus 


Sun-dial lupine in the East seldom equals in profusion of growth 
its sisters of the West, which often cover the hillsides with a carpet of 
bloom. Nevertheless, this common species of the Eastern States is as 
beautiful as any of the others, and deserves a place of honor in our wild 
gardens. In rich loam it will dwindle and die, but if planted in an acid, 
sandy soil, will thrive in cultivation. Although usually bright blue, 
the flowets are occasionally white or lavender, sometimes bordering 
on purple. 

In Texas, one of the lupines commonly called blue-bonnets has been 
named the State flower. 

The sun-dial lupine is found from Louisiana and Florida north to 
Maine and Minnesota. 

The specimen sketched grew near Washington, District of Co- 
lumbia. 


PLATE 6 


BIG WHORTLEBERRY 


Vaccinium membranaceum Douglas 


Snow slides are not to be desited, but after they have mowed down 
the forest of the mountain slopes, exposing the ground to the full sun- 
light, a bushy growth springs up, three or four feet tall, with young 
trees interspersed. Among these shrubs we find whortleberry bushes, 
- Rocky Mountain rhododendron, and other plants that love similar 
conditions of soil and exposure. Here in late summer a delightful 
feast is spread for the traveler, for the big whortleberry bushes are 
loaded with dark purple berries, some of them as large as small cherries. 
A large quantity may be gathered in a short time. The black bears 
also appreciate them, and often are met in these localities, sitting on 
their haunches and sweeping the ripe fruit into their mouths with 
their great paws. In autumn the leaves turn a deep red. 

Big whortleberry is found occasionally in the Rockies, but reaches 
greatest perfection in the Selkirk Mountains, and is especially abund- 
ant at Rogers Pass and in the vicinity of Glacier House at Glacier. 
It ranges from California, Wyoming, and Michigan to British 
Columbia. | 

The specimen sketched was obtained near Hector Station on 
the Canadian Pacific Railway, British Columbia, at an altitude of 
5,000 feet. 


PLATE 7 


PINEBARREN GENTIAN 


Gentiana porphyrio Gmelin 


Pinebatren gentian is a gtaceful and attractive plant. Its deep blue 
corolla lobes, with peculiar ftinges between them, and the curious 
yellow markings on the inside, make a pleasing color combination 
seldom seen in flowers. It frequents moist pine barrens, teaching a 
foot ot more in height, and although the flowers gtow singly on 
the branches, a number of stems usually arise from each root, so that 
the clumps are very showy. 

This gentian blooms from late August into October, and can be 
cultivated if given the moist, acid, peaty soil in which it thrives in 
the wild state. It occurs in the Coastal Plain from Florida to 
southern New Jetsey. 

The specimen sketched was found neat Wilmington, North 
Carolina. 


PLATE 8 


SKELETON FLOW ER 


Lygodesmia juncea (Pursh) Don 


This is a strange-looking plant, a foot tall, with pale pink, starlike 
flowets that close in the afternoon, or vety soon after being gathered. 
Unconsciously, the observer is likely to notice only the flowers, for 
the rushlike stems and scalelike foliage are sage-green and inconspic- 
uous. The plant belongs to the subdivision of the Aster Family that 
includes the dandelion, wild lettuce, and hawkweed, and is chatacter- 
ized by having all the flowers of the head furnished with petallike 
rays, and by a bitter milky juice. 

The skeletonflower is found from Nevada and New Mexico north 
to Minnesota and Albetta. | 

We found it growing on a dry bank, high above the Kootenai 
River, near the junction of this stream with the Columbia River in 
British Columbia, at an altitude of 2,800 feet, and marveled that it 
could thrive in dusty soil, which remains damp only a short time 
after the mountain showets cease. 


PLATE 9 


LAKE LOUISE ARNICA 


Arnica louiseana Fatr 


The hotses had traveled a hard and stony way, very steep in places, 
for we were riding above timber line to visit an alpine lake tucked 
away ina glaciated citque near the headwaters of the Clearwater River 
in British Columbia. There had been no trail to follow, except for the 
first half mile from camp, and we had reveled in the constant succes- 
sion of wild gardens, filled with mountain flowers in the perfection of 
bloom, through which we were passing. Many of the plants were 
crushed by the feet of the ponies, and we wete continually on the 
watch for new varieties. A lon g gtassy slope facing north was being 
conquered, when several yellow flowers appeared, quite different from 
any we had seen before in the mountains. Upon closer examination 
they were recognized as the rate Lake Louise arnica, a composite found 
only in the Canadian Rockies. The best specimens were carefully 
gathered, carried to camp, and sketched without delay, but the thrill 
of seeing them in their native habitat will always be recalled with 
delight. 


PLATE IO 


RED AEs 


Lilium montanum Nelson 


Such hosts of red lilies are seen in the dry woods of the Canadian 
Rockies in some sections in July, that the prodigality of nature seems 
astounding. If perchance a richer soil and more sunlight are available, 
the perfectly developed flowers and the stouter leaves and stems indi- 
cate an appreciation of these favors. But the red lilies are tender things, 
withering speedily when gathered, especially when exposed to sun 
and wind, and they do not easily revive when placed in water. 

The red lily is found in the Rocky Mountains from New Mexico 
to British Columbia, and eastward in the foothills and valleys. 

The specimen painted was gathered in Sinclair Canyon, not far from 
Radium Hot Springs, British Columbia, at an altitude of 3,000 feet. 


PLATE II 


COTTONGRASS 


Eriophorum chamissonis Meyer 


In all parts of the Rocky Mountains of Canada one’s attention is 
drawn in mid-July to the masses of sedge growing along the wet 
borders of alpine lakes, oftentimes out of the water itself: If there have - 
been a few dry days, the cottony heads are waving in the breeze, as it 
fitfully blows over them. Farther away from the lake shote the plants 
become scattered and lose much of the beauty that comes from a 
massed effect. Buffeted by mountain showers and winds, they are in 
their prime only a few days. 

This species of cottongrass is found usually about timber line in the 
Rockies. It is a circumpolar plant, occurring in northern Europe and 
Asia as well as North America. On this continent it perhaps survived 
the glacial period in Wyoming and adjoining States, where it still 
gtows, but since the ice retreated it has spread far into Alaska, and 
eastwatd across Canada to Ontario and even to New Brunswick. 

The sketch was made from specimens gathered at Cotton grass 
Lake, north of Ptarmigan Pass, ten miles north of Lake Louise Sta- 
tion, Alberta, at an altitude of 7,000 feet. 


PLATE 12 


VERNAL IRIS 


Iris verna Linnaeus 


Although the vernal iris is not very well known, it is so lovely a 
wildling that it should find a home in our wildflower gardens. In his 
“Book of the Iris”, Dykes reports his inability to cultivate it, but this 
was probably owing to his failure to recognize its peculiar soil requite- 
ments. It usually grows on wooded hillsides, preferring a mediacid soil. 
Though the whole plant is only about six inches tall, its violet-blue 
flowers with yellow markings at the base of the petals cannot be easily 
overlooked, for they ate very large in proportion tothe grasslike leaves. 
In early spring the blossoms dot the barren fields of the Southern States, 
where real blue violets do not occur, and are often called “violets.” 
Curiously enough, their delicate fragrance adds to the deception, for it 
closely resembles the scent of the garden violet. 

This iris ranges over most of Alabama and Georgia and the states 
adjoining them on the north, but farther northward it becomes tate, 
occurring in but a few favored localities in Kentucky, Maryland, and 
Pennsylvania. 

The specimen painted was found near Beaufort, South Carolina. 


PLATE 13 


ANEMONELLA 
Syndesmon thalictroides (Linnaeus) Hoffmannsegg 


Anemonella, often called rue-anemone, frequents open woods, 
whete it is found in company with hepatica and bloodroot when the 
first warm days of spring call sleeping plants to awaken. The slender 
stems, bearing the fragile green leaves and delicate pink or white flow- 
ets, grow from a cluster of small tuberous roots. These hold so lightly 
tothe soil that they ate easily pulled up, unless care is taken in plucking 
the flowering stems. Anemonella, the only member of its genus, resem- 
bles somewhat its relatives, the true anemones or windflowets, but 
differs in havin g the flowers in clusters, and the leaves divided into 
rounded leaflets. It yields readily to cultivation and is a teal desideratum 
for the wildflower garden. 

Anemonella is a wide-ranging species, extending from Florida to 
New Hampshire and westward to Kansas and Minnesota. 

The specimen sketched was found at Washington, Disttict of 
Columbia. 


PLATE 14 


WHITE TROUTLILY 


Erythronium albidum Nuttall 


White troutlily is one of the daintiest of our early spring flowers, 
and east of the Appalachian Mountains is much rarer than the yel- 
low species, which it closely resembles in habit. The shining green 
leaves are marked with pale mottlings of brownish purple, or in ex- 
ceptional plants are entirely green. The flowers open only in bright 
sunlight, and speedily close and wither when gathered. It is known in 
some sections as dogtooth violet, but as it has no relation to the Violet 
Family, the name troutlily, suggested by John Burroughs, seems most 
appropriate. | 

White troutlily is the common species in the Middle West, from 
Texas to Minnesota, and eastward to the Appalachian Mountain region. 
Here and there its seeds have chanced to cross the mountain barrier 
and, carried down the streams, have lodged along the banks and estab- 
lished colonies in the Piedmont regions from Georgia to northern 
New Jetsey. 

The specimen sketched was obtained in the Potomac Valley above 
Washington, District of Columbia. 


PLATE I5 


HAZEL ALDER 


Alnus rugosa (Du Roi) Sprengel 


The aldets are widespread shrubs known to all who welcome the 
coming of spring. With the exception of the skunkcabbage, their 
blooms are the earliest forerunnets of spring, and almost every swamp 
and sheltered brook where the sun can penetrate is decorated with 
numerous bushes, hung with purple and yellow pendent catkins. The 
pollen, furnished by these in large quantities, is blown by the wind, 
lighting on the little green or purplish knobs of pistillate flowers, 
_ which grow into ripe cones in autumn. Several species of the genus 
Alnus contain in their bark a coloring principle of value, dyeing either 
yellow or orange. With copperas added, a good black may be made 
from it. Before the coming of the white man with his commercial 
colors, alder dye was frequently used by the Indians. 

Thete ate several species of alder in the United States, the one here 
tepresented ranging from Florida to Texas and from Maine to Min- 
nesota. 

The sketch was made from a specimen gathered near Washington, 
District of Columbia. 


PLATE 16 


TARFLOW ER 


Befaria racemosa Ventenat 


While traveling through the South in June, whether by rail or 
automobile, one finds the green fringe of low shrubbery by the road- 
sides dotted here and there with the pink starlike blossoms of the 
tatflower. These shrubs rarely occur in dense vegetation, but usually 
in such places as will permit them to raise their flowery heads above 
the gtass, weeds, and low shrubbery, to beckon the insect sponsors 
necessary for their cross pollination. 

The species ranges from southern Florida to southeastern Georgia. 

The specimen here figured came from a woodland margin along 
the tracks of the Florida East Coast Railroad near Jacksonville, Florida. 


PLATE 17 


ALPINE FIR 
Abies lasiocarpa (Hooker) Nuttall 


The alpine fir, commonly called balsam fir in the mountains, is the 
tree best known to those who follow the trail in the Canadian Rock- 
ies, for it is the substitute par excellence for a soft hair mattress, if the 
bed is properly made, and nosleep is more restful than that obtained on 
such an aromatic couch of “Rocky Mountain feathers”. From the 
numerous blisters in the bark a thick juice may be collected which 
makes an effective dressing for cuts and bruises. The Canada balsam 
used by microscopists in mounting specimens is obtained from a te- 
lated species, the balsam fir. By some of the Indian tribes the fir tree _ 
was called “cho-koh-tung”, meaning blisters. The wood is soft and 
coatse-grained and,though it grows rather rapidly, is not of much value 
commercially. In the lower valleys of the Canadian Rockies the tree 
attains to some size, and at timber line holds the final outposts with © 
the Lyall latches, often affording a striking exhibit of nature’s adapta- 
tion to advetse conditions of soil, temperature, and wind. 7 

This fir has a wide range. It survived the glacial period in the 
southern Rocky Mountains, in Northern Arizona and New Mexico, 
and since the ice retreated has migrated northward along the coast 
ranges to the Olympic Mountains of Washington, thence into Alaska, 
and through the eastern Rockies into Alberta, Canada. 

The specimen sketched was obtained north of Bow Pass, one day s 
tide from the Saskatchewan River, at the foot of Pyramid Peak, at 
6,000 feet elevation. | 


PLATE 18 


OCON EE-BELLS 


Shortia galacifolia Totrey and Gray 


This evergreen, ground-coveting plant was for many yeats one of 
America’s “lost species”. It had been discovered by Michaux, the French 
botanist, during his travels in the mountain wilderness of North Caro- 
lina in 1788, but the exact spot where he found it long remained un- 
known, and the dried specimen he had collected, preserved in Paris, 
was the only proof that such a plant existed. In 1877 the plant was 
rediscovered, and subsequently found to be fairly abundant in a few 
testticted areas. I have not seen it in the wild, but Dr. Edgar T. Wherry 
informs me that it thrives in acid soils on steep slopes along shaded 
mountain brooks, and that the primroselike white flowers, starring the 
mats of winter-bronzed foliage in March, produce a charmingly beauti- 
ful effect. If transplanted into ordinary garden loam it soon dwindles 
and dies, but if given acid humus soil it is not hard to grow in cultiva- 
tion. Oconee-bells is known to the mountaineers as the one-flower 
coltsfoot, but the common name has been given from its abundance 
in the Oconee Valley. 

Oconee-bells is known to grow only in the Blue Ridge and adjoin- 
ing parts of the Piedmont region in North and South Carolina. A close 
relative occurs in Japan, however, indicating that before the glacial 
period the genus must have spread over both northeastern Asia and 
northern North America. The ice advances no doubt exterminated 
some of the species, but the two that chanced to migrate far enough 
to the southward of the line reached by the ice sheets were preserved. 

The specimen painted was grown by Dr. Frederick V. Coville, in 
acid peat-sand soil, in a greenhouse of the United States Department 
of Agriculture at Washington. 


PLATE 19 


VIRGINIA BLUEBELLS 


Mertensia virginica (Linnaeus) De Candolle 


The lovely Virginia bluebells, with their exquisite bright green 
leaves, burst forth in unsuspected places in spring. Each year, after the 
blooming and seeding season, the plants disappear before midsummer, 
and not until another winter has passed and the spring sun and rains 
have enticed them from their hiding places, do we again locate them 
by their tender bronze-green shoots pushing through the moist earth. 
They love the rich soil of river meadows or the banks of streams, and 
cover the ground with their masses of bloom and tender green leaves. 
Virginia bluebells yield easily to cultivation in a wildflower garden, 
but they are not so well known as other members of the Borage Family, 
the forget-me-nots and the heliotropes. In Europe they are much ap- 
preciated in cultivated gardens. 

Virginia bluebells may be found from Georgia northward to New 
York and southern Ontario, and westward to Kansas and Minnesota. 

The specimen sketched was obtained near Washington, District of 
Columbia. 


PLATE 20 


BURGESS MILKVETCH 


Astragalus bourgovit Gray 


Among the numerous members of the Pea Family this dainty plant 
is one of the most appealing. A number of stems grow from a central 
point and, falling carelessly all around, give the impression of a loose 
bouquet, the flowers, on their delicate stems, projecting beyond the 
leaves. The ponies like to eat them, and perfect specimens are difficult 
to obtain where horses have had access to the colonies. 

Burgess milkvetch has a rather restricted range in the northern 
Rocky Mountains, from South Dakota and Montana to British Co- 
lumbia. Usually it is found among partially disintegrated rocks. 

This specimen was gathered at Burgess Pass, seven miles by trail 
from Field, British Columbia, on a northwestern slope, at an eleva- 
tion of 7,500 feet. 


PLATE 21 


GREENDRAGON 


Arisaema dracontium (Linnaeus) Schott 


Greendtagon is a vigorous plant and decidedly decorative, though 
its flower lacks the handsomer coloring of the jack-in-the-pulpit, its 
near relative. It is, however, of similar habit. Its deeply parted leaves 
gtowing on a long stem from the solid globular bulb or corm, reach 
a height of two feet or more. It loves the same rich, moist woods 
ot low ground frequented by the jack-in-the-pulpit, but is rarely so 
abundant. The betrylike fruits of the greendragon ate red-orange in 
color, and are clustered in heads that become conspicuous in early 
autumn. They are much more effective in calling attention to the 
plant than its green flowers or its foliage. 

The tange of the greendragon is rather wide, extending from Texas 
to Florida and northward to Minnesota, Ontario, and Maine. 

This specimen grew along the Potomac River above Washington, 
District of Columbia. 


PLATE 22 


TOAD TRILLIUM 


Trillium sessile Linnaeus 


Unlike most other members of its group, this trilltum has a rather 
pleasant odor, but it does not approach other species in attractive- 
ness, for its curious sessile flowers are dull in color. Normally the 
petals are of a deep maroon color, but in some plants, which ‘show 
no differences, they are pale greenish yellow. It prefers deep, moist 
woods, and is easily overlooked among the fresh growths of April 
or May. 

Toad trillium tsa typical member of the flora of the Middle Western 
States, ranging from Mississippi to Florida, northward to Minnesota 
and western New York; occasionally it crosses the Appalachian Moun- 
tains and pushes down river valleys as far north as Maryland and south- 
ernmost Pennsylvania. | 

The specimen sketched grew on Plummers Island in the Potomac 
River near Washington, District of Columbia. 


PLATE 23 


SOUTHERN MAGNOLIA 


Magnolia grandiflora Linnaeus 


This stately magnolia is one of the most conspicuous trees of the 
southern woods, occasionally attaining a height of seventy feet. It 
proves hardy in cultivation as far north as Washington. The wonderful 
creamy flowers, encircled by the large, glossy, evergreen leaves, spring 
from the ends of almost every branch. Their delightful fragrance im- 
mediately attracts attention when the tree is at the height of its glory 
in June. Several species of beetles patronize the blossoms, enticed by 
the abundant pollen and nectar. 

Today the members of the Magnolia Family found in America ate 
but a remnant of the numerous species that flourished in pre-glacial 
times from the mid-continental plains to the Arctic Circle. The fossil- 
ized trunks found at Amethyst Mountain in Yellowstone Park, with 
specimens of both fruit and leaves, give an indication of their grandeur 
and beauty in former ages. 

Southern magnolia is native throughout the Southern States from 
Texas to Florida and northward to Arkansas and southeastern North 
Carolina. It has been officially adopted as the State flower of both 
Louisiana and Mississippi. | 


PLATE 24 


SOUTHERN MAGNOLIA 


Magnolia grandiflora Linnaeus 


FRUIT OF PLATE 24 


As early autumn approaches, the fruit of the southern magnolia be- 
comes conspicuous, and as it ripens the outer envelope cracks over each 
seed compartment and the crimson seeds protrude from their downy 
coverings. At this stage the tree affords a striking contrast of red fruit 
and glossy green leaves. As time passes, the seeds loosen from the shell, 
but are still attached to the conelike fruit by a slender white thread 
about an inch long, finally dropping to the ground when the wind 
blows them loose. 

Southern magnolia is found native throughout the Southern States, 
from Texas to Florida, northward to Arkansas and southeastern North 
Carolina. 

The specimen painted was taken from the large tree just south of 
the White House, and was given me by Mrs. Coolidge. 


PLATE 24A 


TRUMPETLEAF 


Sarracenia flava Linnaeus 


Anyone who has traveled through the South in spring and has been 
delighted by the fresh verdute of ferns and trees, cannot fail to have 
been attracted by the great numbers of these curious plants, which can 
be observed ftom the car windows. The trumpetleaf is the largest 
representative of the Pitcherplant Family, the yellow flowers measur- 
ing as muchas five inches in diameter, and the yellowish-green tubular 
leaves, ftequently veined with red on the pointed lid, growing two to 
three feet high. The inside of the leaves neat the top has a very smooth 
and slippery waxed surface, so that flies and other insects that ate at- 
tracted by an exudation just above the waxed surface, lose their hold 
and slide to their death in the digestive liquid which the pitchers 
contain. All the members of this family have arrangements for utiliz- 
ing the dead insects to their own advantage. 

The trumpetleaf grows in damp acid soils, from northern Florida 
to the southernmost counties of Virginia. 

The specimen sketched was brought into flower by Dr. F. V. Coville 
in a greenhouse of the Department of Agriculture in Washington. 
These plants ate easy to cultivate if placed in a pot filled with acid soil 
made from a mixture of peat and sand, and this put into another pot 
of two inches greater diameter, the space between being filled with 
sphagnum moss. They should be kept in a cool greenhouse. 


PLATE 25 


REDBUD 


Cercis canadensis Linnaeus 


When the dogwood buds are bursting into bloom in early spring, 
a companion tree, the redbud, is seen throughout our southern woods, 
its knotted branches covered with clusters of purplish-pink, pea-shaped 
flowers. In favorable localities the tree attains a height of forty or fifty 
feet, though usually much smaller. The leaves, which develop after the 
flowers, ate heart-shaped—quite unlike those of most legumes—and 
ate a glossy gteen, turning to yellow in autumn. The flowers are well 
supplied with nectar, and are most attractive to bees, who visit them 
in large numbers. In some regions the redbud is known as Judas-ttee, 
a name properly applied to the Old World species, Cercas stlequastrum. 

The tree has a wide range, from Texas to Florida and northward. 
Though best developed in the South, it has been able to migrate north 
as far as Minnesota and northern New Jersey, and even a short distance 
into southern Ontario. 

The specimen drawn was collected near Washington, District of 
Columbia. 


PLATE 26 


TALL LARKSPUR 


Del phinium elongatum Rydberg 


Tall larkspur is found in rich mountain valleys, where it loves to 
grow among the willow clumps that partially shade the soil about its 
roots. It is usually from two to four feet in height, and if free from 
other plants has a striking clump of basal leaves, above which rise the 
long spikes of rich purplish-blue flowers, swaying in the breezes. The 
power to fertilize themselves having been lost, cross-pollination is 
effected by bees and butterflies, whose tongues reach into the deep 
recesses of the flowets whete the nectar is hidden. The name Delphi- 
nium was given by Linnaeus, from a fancied resemblance of the parts 
of the flower to a dolphin. 

Tall larkspur has a narrow tange, being found only from Colorado 
to Alberta. 

The specimen drawn was collected on the Clearwater River, fifty 
miles north of Lake Louise Station, Alberta, at an altitude of 4,500 feet. 


PLATE 27 


RHODORA 


Rhodora canadensis Linnaeus 


Rhodotra is sutrounded with romantic interest, because of the atten- 
tion drawn to it by Emetson’s verses. It is the only plant of its genus. 
The tosy-purple flowers, usually appearing before the leaves, burst sud- 
denly into bloom and form masses of color on wet hillsides or along the 
margins of acid swamps. Their shape suggests a relationship to the 
thododendron, with which this plant is grouped by some botanists. 
Rhodora bushes grow from one to three feet high, and are inconspic- 
uous except when in flower. | 

The range of rhodora is rather limited; presumably it survived the 
glacial period near the margins of the ice sheets, and it now occupies 
glaciated territory from northeastern Pennsylvania to Newfoundland. 

The specimen sketched was collected at Pocono Manor, Pennsyl- 


vania. 
THE RHODORA 


In May, when sea-winds pierced our solitudes, 
I found the fresh Rhodora in the woods, 
Spreading its leafless blooms in a damp nook, 

_To please the desert and the sluggish brook. 

The purple petals, fallen in the pool, 

Made the black water with their beauty gay; 
Here might the red-bird come his plumes to cool, 
And court the flower that cheapens his array. 

Rhodora! if the sages ask thee why 

This charm is wasted on the earth and sky, 

Tell them, dear, that if eyes were made for seeing, 

Then Beauty is its own excuse for being: 

Why thou were there, O rival of the rose! 

I never thought to ask, I never knew; 
But in my simple ignorance suppose 
The self-same Power that brought me there brought you. 
RatpH WaLpDo EMERSON. 


PLATE 28 


PICKERELWEED 


Pontederia cordata Linnaeus 


On the flats bordering the Anacostia River in Washington, the rank 
growths of the various marsh plants form a broad belt of vegetation 
of striking appearance. Perhaps because of their color, the flowers of 
pickerelweed are not so conspicuous as those of some other members 
of the colony, but in spite of this its glossy green leaves, borne well 
above the surface of the water, and its ragged spikes of small blue or 
lavender flowers, continuing in bloom through most of the summer, 
ateadelight to behold. Without a boat it is almost impossible to gather 
the blooms, growing from the soft mud that supports the outer pha- 
lanxes of aquatic plants. The flowers of the pickerelweed, which last 
buta single day, are in three forms. They do not produce seeds without 
the aid of insects, and it is an interesting study to examine them in 
detail with a glass and note the complicated structure by which they 
ate able to obtain the greatest amount of benefit from their insect 
visitors. Giulio Pontedera, professor of botany at Padua about 1730, 
is commemorated by the generic name. 

Pickerelweed is found from Florida to Texas and northward to 
Minnesota and Nova Scotia, and grows also in tropical America. 

The specimen sketched was obtained near Washington, District of 
Columbia. 


PLATE 29 


CREEPING HOLLYGRAPE 


Berberis repens Lindley 


The shiny, prickly leaves of the hollygrape are so nearly like holly, 
that upon first glance we may think we have found that tree, reduced 
to a bush or low plant creeping over the ground. Closer inspection 
reveals many differences, for the berties, growing in a bunch, are of a 
lovely blue color—almost like small grapes—with plenty of bloom. 
They are rather pungent and sour to the taste, but are good for jelly or 
for making a refreshing drink, most welcome to quench the thirst 
when climbing a mountain side. As autumn approaches, the leaves 
change to red, either all over or around their borders, and are then most 
attractive in coloring. They remain upon the plant all winter. 

Creeping hollygrape is found from California and New Mexico to 
Alberta and British Columbia. The Oregon hollygtape, Berberts aqus- 
folium, often known as Oregon grape, has been designated the State 
flower of Oregon, by vote of the legislature. Three species of holly- 
gtape occur abundantly in the Pacific Northwest. 

The specimen sketched was gathered in Sinclair Canyon, Columbia 
River Valley in British Columbia, at an altitude of 3,500 feet. 


PLATE 30 


RED CHOKEBERRY 
Aronia arbutifolia (Linnaeus filius) Elliott 


The red chokeberry is a smallshrub found in low grounds, swamps, 
and dry open woods, and though not particular as to moisture in choos- 
ing a situation, usually prefers rather acid soils. The cymes and the 
under surface of the leaves ate woolly, and in spring, when in full 
bloom, it is a graceful and handsome plant. 

Examination of the individual flowers will show them to resemble 
those of the pear tree in structure, and the plant is referred by botanists 
to that group of the Rose Family which includes the pear, apple, and 
hawthorn. 

Red chokeberry may be found from Louisiana and Florida to 
Minnesota and Nova Scotia. 

The flowetssketched grew neat Washington, District of Columbia. 


PLATE 31 


RED CHOKEBERRY 


Aronia arbutifolia (Linnaeus filius) Elliott 
FRUIT OF PLATE 31 


The fruit of the red chokeberry ripens in August or September, and 
later in the season the whole bush becomes a gorgeous mass of orange 
and scarlet color. The fruits are shaped like miniature pears, and this, 
together with their bright coloring, often tempts the stranger to taste 
them, but the result is sure to be a disappointment, for they ate exces- 
sively sour as well as bitter. The birds do not seem to mind this feature, 
however, and consume them greedily during the winter months. A 
bush or two should be planted in the garden of every bird lover. 

The ted chokeberry ranges throughout the eastern United States and 
into southernmost Canada. 

Like the flowers, the spray of berties sketched is from the vicinity of 
Washington, District of Columbia. 


PLATE 31A 


DEVILSCLUB 


chino pana horridum (Smith) Decaisne and Planchon 


The devilsclub is a sturdy shrub, rising above the ground four or 
five feet on stout prickly stems. The maplelike leaves spread from 
the stems about a foot below the red berries, and hide the ground, so 
that one is not aware of its terrible spines until he tries to walk 
through a thicket. No heavy woolen garment or leather shoe 1s stout 
enough to withstand the bristling, hard, gray spines. Without the help 
of an axe and a strong arm behind it, the thickets of devilsclub in 
the Selkirk Mountains are often almost impenetrable. The scarlet 
berries ate very showy in late summet. 

This plant belongs to the Aralia Family, which includes other spiny 
shrubs, such as the Herculesclub of the southeastern United States, as 
~ wellas ginseng and wild-sarsaparilla. 

The range of the devilsclub is from Oregon, Montana, and Michi- 
gan to Alaska. 

The specimen sketched was obtained near Field, British Columbia, 
at an altitude of 4,000 feet. 


PLATE 32 


CRESTED IRIS 


Iris cristata Aiton 


The crested iris is dwarf in habit and its lance-shaped leaves of 
bright green taper at each end. The flowers, which appear in May, 
seem out of proportion to the size of the plant. Their broad outer divi- 
sions or petals have yellow, raised flutings along the center, which give 

rise to the name. This lovely plant yields easily to cultivation in a wild 
- gatden, being telatively indifferent as to soil reaction, but requiring 
plenty of humus and enough rocks to insure good drainage. 

The crested iris may be found from Georgia to Maryland and west to 
Missouri and southern Indiana. 

This specimen was sketched at Plummets Island in the Potomac 
River near Washington, District of Columbia. 


PLATE 33 


LILY TWAY BLADE 
Liparis lilitfolia (Linnaeus) Richard 


This little orchid is inconspicuous whete it grows, on account of 
its protective coloring, which blends so perfectly with its surround- 
ings, though a fascinating plant when examined closely. It blooms in 
May and has two rich green leaves that clasp the flower stem and grow 
from a solid perennial bulb. It is the easiest to cultivate of all our native 
orchids, not being particular as to the reaction of the soil, although it 
ptefers an abundance of humus. 

The lily twayblade extends from Missouri to Georgia and north- 
watd, and since the ice of the glacial period retreated has succeeded in 
migtating as far north as Minnesota and Maine. 

The specimen sketched grew on High Island in the Potomac River 
neat Washington, District of Columbia. 


PLATE 3 4 


MISSOURI PRICKLYPEAR 


Opuntia polyacantha Haworth 


The Missouri pricklypear is one of the commonest of the cactuses. 
The flowers ate so beautiful that one forgets the wicked spines and the 
still more dangerous spicules, which are found on the thick stems of 
flat joints, until one endeavors to gather them. In the bright sunshine 
of eatly morning thedry prairies in some sections are dotted with masses 
of pale sulphut-yellow flowers, turning salmon in the late afternoon as 
they fade. The sensitive stamens ate sometimes yellow and sometimes 
ted, while the stigma-lobes, in the center, are always green. The irritable 
stamens ate one of the provisions which nature makes to bring about 
cross-pollination. Bees visit the cactus flowers to obtain the nectar. 
When one of them settles upon the stamens, which spread widely apart 
in bright sunlight, these at once turn inward and downwatd, covering 
the insect and depositing the pollen on its back, legs, and head. This 
pollen is then carried by the insect to the next flower and dropped upon 
its stigma-lobes. Below the bright-colored petals is the spiny ovary, 
which ripens into a dry, many-seeded fruit, this pricklypear being 
one of the few which are not juicy. 

The Missouri pricklypear may be found in dry places from New 
Mexico, Missouri, and Wisconsin to Alberta and British Columbia. 

The specimen sketched was obtained near Medicine Hat, Alberta, 
Canada, at an altitude of 3,500 feet, a locality near the northern range 
of this species and also near the northern limit of the Cactus Family. — 


PLATE 35 


BUTTERFLY WEED 


Asclepias tuberosa Linnaeus 


The butterflyweed is probably our most beautiful orange-colored 
wild flower. Growing in poor sandy soil, it forms masses of brilliant 
color wherever it finds a congenial foothold. The plants are visited by 
hosts of butterflies, some of them especially adapted to the ctoss- 
pollination of the flowers, which have entirely lost the ability to fer- 
tilize themselves. Only insects with long tongues can reach the nectar 
hidden in the deep recesses of the complicated blossoms, whose sttuc- 
ture definitely places the plant in the Milkweed Family. Curiously 
enough, however, its juice is not milky. The Indians are said to 
have used the long roots of this and other milkweeds as a remedy 
for vatious maladies, and herb doctors of a later day use them under 
the name of pleurisy-root. Linnaeus dedicated the family to Aes- 
culapius on account of its alleged healing qualites, though the name, 
as he spelled it, is a Latinized corruption. The plant yields easily to 
cultivation, provided it is planted in dry, sterile soil, and should be 
grown in every wildflower garden with bright sunny exposure. 

Butterfly weed hasa wide range, extending from Florida to northern 
Mexico and north to Maine, Ontario, Minnesota, and Colorado. 

The specimen sketched was found neat Washington, District of 
Columbia. 


PLATE 36 


SKUNKCABBAGE 


Spathyema foetida (Linnaeus) Rafinesque 


This first plant to flower in spring is easily found in swampy places, 
where the richly colored, hooded spathe is seen pushing its way through 
the moist earth, sometimes before the ground is free of snow. When 
one peeps inside the hood, the small flowers are found dotting the 
spadix more or less regularly. The rank insistent odor attracts many 
flesh flies. The leaves come through the earth before the flower has 
faded, and grow rapidly into showy, light green clumps, from one to 
three feet high. At this time the odor is very strong. The fruit ripens in 
September. 

Like most of the members of the Arum Family, the skunkcabbage 
is rather southern in its distribution, ranging from Missouri to Florida 
and northward, locally reaching Minnesota and Maine, or even Nova 
Scotia. | 

The specimen sketched was found along Piney Branch, Washing- 
ton, District of Columbia. 


PLATE 37 


RED-OSIER DOGWOOD 


Cornus stolontfera Michaux 


The red-osier dogwood is an attractive shrub, not only when in 
bloom but also in the early fall, when its bunches of bluish-white bet- 
ties ate borne in abundance, and the leaves change in color to scarlet, 
purple, ot gold. The Indians used the scraped inner bark for smoking 
purposes, and preferred it to any other plant, giving it the name ‘kinni- 
kinnick”. In winter the slender, graceful, purplish-red stems are con- 
spicuous and distinctive. 

Red-osier dogwood may be found from Virginia to Newfoundland, 
and from Mexico to Alaska, and at many places in the interior of the 
continent. 

The specimen sketched grew at Radium Hot Springs, in the Co- 
lumbia River Valley, British Columbia, at 3,000 feet elevation. 


PLATE 38 © 


BIRDSFOOT VIOLET 


Viola pedata Linnaeus 


The birdsfoot violet is one of the most beautiful members of the 
Violet Family. The velvety purple color of the two upper petals, 
combined with the pale blue-violet shade of the three lower ones, 
contrasted with the bright orange anthers nestling in the center, im- 
mediately attracts the attention of all who love wild flowers. Bumble- 
bees, also yellow butterflies, visit the flowers and partake of the sweets 
prepared for their enjoyment. When soil and exposure are favorable, 
the ground is purple with the lovely blossoms, the absence of scent 
being the only flaw in their perfection. 

This plant prefers a dry situation where the soil is poor, sterile, and 
acid, and should not be transferred to a wildflower garden unless satis- 
fied in this respect, for in ordinary rich loam it will promptly die. It will 
thrive best if planted in coarse gravel richly charged with decaying 
wood and so rendered thoroughly acid. The small bulblike rootstock 
is so poorly anchored in the soil and so easily lifted from its moor- 
ings, that frequently it comes up when one attempts to pick the 
flowers. Great care should therefore be taken in gathering them. 

This violet is found from Louisiana to Florida, Minnesota, and 
Massachusetts, the dark purple variety being much more frequent 
in the southern portion of the range. 

The specimen sketched was obtained neat Washington, District of 
Columbia. 


PLATE 39 


VIRGINIA SPIDERWORT 


Tradescantia virginiana Linnaeus 


The Virginia spiderwort loves the rich bordersof woods and thickets, 
and is loveliest in the morning, when its blue petals open wide, showing 
the golden anthers in sharp contrast. The plant continues in bloom for 
some time, new flowets opening each morning, and enticing the bees 
to a fresh feast of nectar. These insect visitors ate necessary to ctoss- 
fertilization, and carry from one blossom to the next a heavy load of 
pollen. 

The genus is named for John Tradescant, gardener to King Charles I 
of England, and belongs in the same family as the dayflower. [his and 
the Pickerelweed Family are closely related. 

The Virginia spiderwort may be found from Virginia to Arkansas, 
northward to South Dakota and southern New York. 

Thespecimen sketched grew neat Washington, Districtof Columbia. 


PLATE 40 


LEATHERFLOWER 


Clematis viorna Linnaeus 


The leatherflower is not so showy as the other membets of the 
clematis group, nevertheless its graceful stems and leaves and reddish 
purple blossoms are not uninteresting. The sepals are remarkable in 
being a sixteenth of an inch thick, as if made of leather instead of the 
delicate tissue usual in flowers in which petals are lacking and the sepals 
ate required to take their place. The feathery fruit, more attractive than 
the flowers, is erect and silky, each individual “seed” possessing a tail 
almost two inches long, by means of which it may be carried by the 
wind, when ripe, to a favorable situation. 

This scrambling vine may be found in thickets where the soil 1s 
rocky but rather rich, from Alabama and Georgia northward to Ohio 
and Pennsylvania. | 

The sketch was made from a specimen gathered near Washington, 
District of Columbia. 


PLATE 41 


PURPLE SAXIFRAGE 


Saxifraga oppositifolia Linnaeus 


The putple saxiftage ts truly an alpine plant. In the Canadian Rock- 
ies itis found above ttee line near the melting snows on southern slopes, 
where it comes quickly into bloom in the long days of early summer, 
and as quickly is past, leaving the matted rosettes of tiny, bright green 
leaves, dotted with dull red seed capsules, to reward our search, if, per- 
chance, we ate a few days too late to find it in bloom. It delights in 
disintegrated limestone, often growing in cracks between the tocks. 
Though plentiful in its chosen situation, it is not often seen by visi- 
tors, who must make a hard climb to reach its haunts. In Alaska and 
near the Arctic Circle it finds the most favorable conditions for perfect 
development, growing into large mats. 

The purple saxifrage is typical of Arctic regions throughout the 
world, and no doubt survived the glacial period close to the margins of 
the great ice sheets. W hen these withdrew, it followed back on the bate © 
rock surfaces. It is now found occasionally in the northern United 
States, from Wyoming to Vermont, and more abundantly northward. 

The specimen sketched grew on the slopes of Fossil Mountain neat 
Baker Lake, seven miles northeast of Lake Louise Station, Albetta, 
at an altitude of 8,000 feet. 


PLATE 42 


FLAME AZALEA 


Azalea lutea Linnaeus 


The flame azalea is the most conspicuous of the native membets of 
this genus. Its brilliant orange or yellow coloring, frequently suffused 
with ted, attracts attention even from a distance, and when the 
mountain sides are flecked with it, the effect is particularly striking. 
The green leaves, which ate well developed before the flowers open, 
add greatly to the beauty of the plant. It yields easily to cultivation and 
under favorable conditions, when grown with other plants requir- 

ing an acid soil, is one of the loveliest native shrubs for planting. 
_ Flame azalea is a typical member of the flora of our Southern 
Appalachians, ranging from the uplands of Georgia northward, and 
being abundant as far as West Virginia. In the mountains of Pennsyl- 
vania it is rate,and though reported many years ago to grow in south- 
ern New York State, it has long since disappeared from there as a 
native plant. 

The sketch was made from a specimen obtained near Linville, 
North Carolina. 


PLATE 43 


RABBITBEAN 


Cracca virginiana Linnaeus 


The gray-green foliage of the rabbitbean makes a delightful back- 
ground fot its straw-colored, pea-shaped flowets, touched with red, and 
ctowded at the end of a stiff stem. The plant blooms in early summer 
and is to be found in dry, sandy, acid soil. Should you wish to gather 
a bunch, you will find the stems and the unusually long roots sur- 
ptisingly tough, and a serviceable substitute for twine, if necessity 
demands. It is, indeed, commonly known in the South as devil's shoe- 
string. 

The seeds are in bean-shaped pods, which are frequently rifled by 
weevils, so that few of them ever teach maturity. 

The Indians used a tropical American species of this genus as fish 
poison in the same manner in which they employed many other plants, 
throwing the macerated stems into quiet streams or ponds, with the 
result that the fish became stupefied and floated on the surface of the 
water, so that they were easily taken. 

Rabbitbean ranges from Texas to Florida and northward to Mani- 
toba and Ontario. 

The specimen sketched was collected near Washington, District of 
Columbia. 


PLATE 44 


TULIPTREE 


Liriodendron tulipifera Linnaeus 


This beautiful tree is a joy to behold at any season of the year. Its bare 
gtay branches outlined against the winter sky impress one with theit 
vigor of growth and sturdy health, and when the warmer days and 
Aprilshowers swell the buds, and the tiny young leaves appear, the tree 
bursts into its supreme glory. If in a sunny situation, it is soon covered 
with green tulip-shaped flowers, each cup beautifully decorated with 
a brilliant orange bar, to entice the visiting bees. In autumn the leaves 
are a mass of orange and gold. 

The tuliptree is the only member of the genus Liriodendron in 
America, though a closely related species flourishes in central China, 
these two being the sole survivals of the Cretaceous Period, when 
members of the genus were widely distributed in America and Europe. 
Though it reaches its greatest size in the lower Ohio Basin, sometimes 
growing almost 200 feet high, it is found in the eastern United States 
from Louisiana to Florida and northward to Michigan and southern 
Vermont. 

The wood has avariety of commercial uses, while the bark, especially 
that of the roots, yields a tonic and heart stimulant. The blossom of the 
tuliptree is the State flower of Indiana. 

The specimen sketched was obtained at Washington, District of 
Columbia. 


PLATE 49 


TRUMPET HONEYSUCKLE 


Lonicera sempervirens Linnaeus 


While tramping through open woods or along streams in low 
ground, the attention may be attracted toa bit of red color quite in con- 
trast to the brown leaves and gray tree trunks or low-growing bushes. 
Closer inspection reveals the gray stems that lead to the leafy shoots 
above, whete the delicate trumpet-shaped flowers are clustered at the 
ends of the branches. Few vines ate more attractive; the plant seems 
to poise itself in the most graceful way as it climbs from one support- 
ing shrub to another. 

The flower is a great favorite with humming birds, which fre- 
quently ate seen probing the trumpets to obtain the delicious nectar 
to be found in them. 

The fruit is a brilliant scarlet berry. The plant is a great addition 
to any wild garden. 

Trumpet honeysuckle ranges from Texas to Florida, and north- 
watd to Nebraska, its northern limit being reached in New York 
and southern New England. 

The specimen sketched was collected at Yemassee, South Carolina. 


PLATE 46 


RED BUCKEYE 


Aesculus pavia Linnaeus 


The red buckeye is a straggling, inconspicuous shrub in the south- 

ern woods until it comes into bloom, when it immediately attracts 
attention by its bright red flowers which ate borne in a loose spike. 
The stems of the new growths also ate red at bloomin g time, and the 
tender green leaves with their red stems make an appropriate setting 
for the flower spikes. It is usually a shrub three or four feet high, 
but in favorable situations it sometimes attains tree size, although 
nevet approaching the stature of its relatives, the Ohio buckeye and 
the horsechestnut. 
Red buckeye is a southern species, ranging from Texas to Florida, 
and extending northward as far as southern Missouri and southeastern 
Virginia. | 

The specimen sketched was collected near Beaufort, South Carolina. 


PLATE 47 


ROSE PAINTBRUSH 
Castilleja pallida (Linnaeus) Kunth 


Crossing alpine meadows above tree line and on high passes in the 
Canadian Rockies, one often finds the drier ground covered with masses 
of tose paintbrush, growing in company with saxifrages and forget- 
me-nots, wherever soil resulting from the disintegrating rock has been 
deposited. The rose paintbrush varies from two to eight inches in 
height, according to altitude and local conditions. The leafy bracts, 
often mistaken for petals, range in color from greenish-white or pale 
yellow to various shades of mulberry or dull pink. The actual flowers 
have a dull-colored corolla, and are concealed between the bracts. The 
plant belongs to the Figwort Family. 

Rose paintbrush grows from Alberta and British Columbia to 
Alaska, and also in Siberia. 

The specimen sketched was obtained on the Clearwater River thirty 
miles north of Lake Louise Station in British Columbia, at an altitude 
of 8,000 feet. 


PLATE 48 


SHOOTINGSTAR 


Dodecatheon meadia Linnaeus 


Shootingstar is not particular in choosing a habitat, for it is found 
in open woods, on moist hillsides, or where the meadows broaden 
into prairies. It belongs to the Primrose Family, and is distantly related 
to the Asiatic cyclamen familiar in cultivation, being in fact some- 
times called wild cyclamen. It thrives in rich garden soil, where the 
flowers often become larger than in the wild state, and it should find 
a place in our gardens. | 

This species of shootingstar has a rather wide distribution, ranging 
through the prairies, where the flowers are often red, from Texas to 
Georgia, and northward into Manitoba; it also extends eastward 
through the Appalachians, reaching the Piedmont from North Cato- 
lina to Pennsylvania. The genus Dodecatheon is best represented in 
the West, where many species occur. 

The specimen sketched was obtained near Washington, District of 
Columbia. 


PLATE 49 


PRAIRIE PENTSTEMON 


Pentstemon erizanthera Pursh 


Praitie pentstemon is one of a large genus of plants, embracing 
about one hundred and forty species, all of which ate natives of North _ 
America. Wherever present they are likely to be found in great 
numbers, especially in the West, where they are very conspicuous. [his 
species grows in small clumps on dry hillsides. Its large flowers are 
wonderfully varied in coloration, ranging from blue, through various 
shades of dull purple, to pale pink. They belong in the Figwort Family. 

The ptaitie pentstemon may be found from Nevada, Nebraska, and 
North Dakota to British Columbia and Washington. 

The specimen sketched was obtained near Sinclair Hot Springs, in 
the Columbia River Valley, British Columbia, at an elevation of 2,500 
feet: 


PLATE 5O 


WILD SWEET CRAB 


Malus coronaria (Linnaeus) Miller 


What sweeter blossoms are to be found in spring than those of the 
wild sweet crab? Itis usually a low bushy tree, growing perhaps twenty 
feet high, with tangled branches making a flat top, quite inconspicuous 
in its wild surroundings. But when early spring is past, and the bushes 
are masses of tender green, the pink buds appear, and soon the whole ts 
covered with lovely flowers, whose sweet scent is wafted far on every 
breeze. The fruit, also, is sweet-scented, and can be made into elegant 
delicious jelly. 

The wild sweet crab is a native of the Central States, extending from 
Louisiana and Alabama northward to Michigan and Ontario, but in 
cultivation over a much wider range. 

This specimen was collected near Washington, District of Columbia. 


PLATE §1 


PITCHERPLANT 


Sarracenia purpurea Linnaeus 


The pitcherplant is found in peat bogs, where the acid soil provides 
ideal conditions for its successful growth. The pitcher-shaped leaves 
gtow from a central crown, and ate partially filled with water and a 
digestive substance. The inner surfaces of the leaves ate lined with 
bristles which project downward, and these prevent many small insects 
that slide into the water from escaping. Thus they ate trapped, drowned, 
and digested. These dead insects are also used as food by the larvae of 
sevetal species of sarcophagous flies, which are instrumental in the 
cross-pollination of the flower, and ate always found where the pitchet- 
plant grows. 

The flowers are borne on a stem from six inches to two feet tall 
a vigorous plant often yielding seven or eight blossoms. . 

A cool greenhouse is necessary for successful indoor cultivation. It 
is well to place the plant in a flower pot filled with acid soil made from 
a mixture of peat and sand, and to set this pot inside another of two 
inches greater diameter, the space between the two being filled with 
sphagnum moss, which should be kept moist. 

The pitcherplant is one of the plants that was pushed southward by 
the ice cap during glacial times. Since the great ice sheet retreated it has 
been gradually moving northward, and now tanges from Florida to 
Kentucky and lowa, and north to Labrador and Manitoba. 

The specimen sketched was collected in eastern Maryland. 


PLATE §2 


PRAIRIE-SMOKE 


Szeversia ciliata (Pursh) Don 


This pretty and graceful plant grows in grassy meadows, where its 
ted flowers, which resemble buds, its ctimson stems, and plumed fruit 
immediately attract attention. In late summer the silky fruit heads 
give to dense patches of the plants dispersed over the plains, a purplish 
hazy appearance, when viewed from a distance. 

The plant belongs to that group of the Rose Family which in- 
cludes the cinquefoils and barren-strawbetries,and is most nearly related 
to the geums, being in fact listed in some books as Geam triflorum. 

As its name suggests, this plant is typical of the prairie region of the 
- United States, ranging from New Mexico to Missouri and northward. 
It extends well up into the eastern valleys of the Rocky Mountains, as 
far north as Alberta, and has also migrated across southern Canada and 
the northern United States as far as Maine. 

The specimen sketched was collected near Banff, Alberta, Canada, 
at an altitude of 4,000 feet. 


PLATE 53 


WINTERBERRY 


Lex verticillata (Linnaeus) Gray 


In spring, when all nature is awakening, we easily overlook this 
inconspicuous shrub, from four to six feet tall, with tender leaves 
and tiny flowers, growing indamp acid ground among the other dent- 
zens of neglected places. But when autumn passes and the stems ate 
stripped of their leaves, the fine red berries come into their own, and 
lend a delightful touch of color to the winter landscape. The whole 
top of the bush is covered with berries, and it then vies with its cousin, 
the holly, in beauty and interest, and in radiating Christmas cheer 
and good will. 

The berries stay on the branches till late winter, and are rarely eaten 
by birds. A form with yellow fruit has been found in New England. 

Another member of the genus Ilex 1s the well-known shrub, maté, 
whose leavesare largely used in South America for making a beverage 
similar to Chinese tea. From yaupon, an Lex of our Southern States, 
the Indians make a stimulating drink, and it is now being placed on 
the market, under the name Cassina, as a substitute for tea. 

Winterberry ranges from Missouri to Florida, and northward to 
Wisconsin and Nova Scotia. 

The specimen sketched was collected near Washington, District 
of Columbia. 


PLATE 54 


SWEET AZALEA 


Azalea arborescens Pursh 


The sweet azalea is one of the contributions to our flora from the 
Appalachian Mountains, where so many attractive plants were found 
by the early botanists. Its delightfully fragrant, spicy, white flowers 
appear in June when the leaves are well developed and afford a fine 
- green background for the blossoms. The foliage often turns brilliant 
red in late autumn. 

The plant loves a well drained, deep, moist, acid soil, and under 
favorable conditions becomes a spreading clump, which blooms freely. 
Itis perhaps the largest of our native azaleas, occasionally attaining a 
height of twenty feet. 

Sweet azalea occurs in the mountains from Georgia northward 
into Pennsylvania. 

The sketch was made from a plant found in the vicinity of Linville, 
North Carolina, at the foot of Grandfather Mountain. 


PLATE 55 


KRUHSEA 
Kruhsea streptopoides (Ledebour) Kearney 


Anyone who has visited Glacier House, and walked to the foot of 
the Ilecillewaet Glacier, may have noticed beds of shiny green-leaved 
plants suggestive of a small Solomonseal. The tiny greenish, bell- 
shaped flowers hang from the under side of the stem, however, and are 
usually missed by the transient visitor, whose efforts ate centered merely 
on climbing the trail to reach the edge of the ice. This tare member 
of the Lily-of-the-valley Family has a somewhat restricted range, and 
is especially interesting because it is one of those plants common to 
both the American and Asiatic shores of the Pacific Ocean. 

It may be found from northern Washington tosouthern Alaska and 
in the Selkirks of British Columbia; also in Japan and Siberia. 

The specimen sketched gtew at Glacier, British Columbia, at an 
elevation of 3,500 feet. 


PLATE 56 


KRUHSEA 


Kruhsea streptopotdes (Ledebour) Kearney 


. FRUIT OF PLATE 56 


The change wrought in vegetation during a few weeks of growing 
weather is very great in mountain regions at the latitude of Glacier 
House, and when autumn approaches,the tiny green flowersof Kruhsea 
have developed rapidly into large, pulpy, red berries, which contrast 
strikingly with the yellow leaves and soon fall to the ground. 

On this continent Kruhsea grows from northern Washington to 
southern Alaska, and in Asia it is recorded from both Japan and Siberia. 

The specimen sketched was obtained at the same locality as the 
flowets shown in the preceding plate, at Glacier, British Columbia, at 
3,500 feet elevation. | 


PLATE 56A 


ARETHUSA 


Arethusa bulbosa Linnaeus 


The arethusa has a single large, one-sided flower with a delicate 
scent like that of fresh red raspberries. The recurved lip, with its 
fringes, forms a capital landing platform for visiting insects. As with 
many other orchids, the bees ate frequent visitors to this plant. The 
flower is so constructed that the bee, in raising his head to depart after 
sipping the nectar, comes in contact with a few soft pellets of pollen, 
which ate deposited upon his head from the helmet-shaped anther. 
Some of this pollen may be transferred to the stigmas of the next flower 
that he visits, although more often it is brushed off by other parts of 
the flower. Because of the infrequency of cross-pollination seeds rarely 
Matutfe. 

The name was given to the plant by Linnaeus, who tecalled the 
myth of the nymph Arethusa, changed by Diana into a fountain, in 
order to protect her from the river god Alphaeus, who fell deeply in 
love with her on seeing her at her bath. 

Owing to the great demand for this orchid by European collectors, 
it has been nearly exterminated in many sphagnum bogs whete it 
formerly grew in great abundance. 

Arethusa may be found from North Carolina ere to Maine 
and Newfoundland, and westward to Indiana and Minnesota. 

The specimen sketched was obtained fromaswampa few miles east 
of Washington, District of Columbia, where the plant is extremely rare. 


PLATE 57 


PALE LA DYSLIPPER. 


Cypripedium acaule Aiton 


The pale ladyslipper is even lovelier than the common form of 
this beautiful orchid, which has pink flowers. The pale form is fre- 
quent in the North, but one whoisso fortunate as to find it in the more 
southern part of its range, experiences a thrill that is not likely to be 
- forgotten. If the soil is kept strongly acid, the plant will readily yield to 
culture in a wildflower garden, and will flourish in either dry or moist 
situations, and in sun or shade. A dressing of pine needles or oak leaves 
will help to conserve the moisture, as well as the acidity of the soil. 
No attempt should be made, however, to cultivate it in seer garden 
soil, for there it is sute to die. 

The pale ladyslipper may be found from North Carolina and 
Tennessee northward to Manitoba and Newfoundland. 

The specimen sketched grew near Washington, District of Columbia. 


PLATE 58 


QUAKERLADIES 


Houstonia caerulea Linnaeus 


Quakerladies, sometimes called bluets and innocence, are among 
our earliest spring flowers, and delight flower lovers by their dainty 
growth and faint, sweet odor. Occurring plentifully in moist meadows 
and wayside places, they sometimes completely carpet the ground. They 
may be gathered freely, without fear of extermination. They continue 
blooming into early summer, and frequently put forth a second bloom 
in late fall. No wildflower garden would be complete without them, 
a tather sterile and acid soil and a fair amount of sunshine being all that 
they ask. 

Linnaeus named this plant in honor of Dr. William Houston, a 
young English botanist, who died in South America after an exhaust- 
ing collecting trip around the Gulf of Mexico in 1733. 

Quakerladies are widely distributed, being found from Georgia and 
Alabama northward to eastern Canada and Michigan. 

The plant sketched grew at Washington, District of Columbia. 


PLATE $9 


BEARBERRY HONEYSUCKLE 


Lonicera involucrata (Richardson) Banks 


Beatberry honeysuckle is a plant that is conspicuous in July when 
the fruit ripens. The coarse, hairy leaves are of a dark rich green, and 
the twin berries, glossy black in color, ate surrounded by a red frill, a 
combination which makes the bush very decorative. The unpreten- 
tious sttaw-colored flowers may sometimes be found on the younger 
branches along with the fruit produced by those that come into bloom 
earlier. If the bush 1s shaken, the ripe fruit falls easily. Its disagreeable 
flavor has gained for it the name of skunkberry in some regions. 

Bearberry honeysuckle may be found from Quebec to Michigan, 
New Mexico, and California, and northward to Alaska. 

The specimen sketched was collected near Hector, British Colum- 
bia, at an elevation af 4,000 feet. 


PLATE 60 


PINK FLEABANE 


Erigeron caespitosus Nuttall 


The pink fleabane may be seen in great perfection in June in the 
upper Columbia River Valley. It seems to delight in dry, sandy soils, 
and especially after a shower, its graceful clumps of daisylike flowers, 
vatiously shaded from white to pink or pale purple, ate a delight to the 
eye. It is a member of a group of plants widely distributed in North 
America, and represented in the Rocky Mountains by a hundred or more 
Species. | 

Pink fleabane ranges from Colorado and Utah to the Yukon. 

The specimen drawn was collected in the Saskatchewan River 
Valley, fifty miles north of Lake Louise, Alberta, at an altitude of 
3,500 feet. 


PLATE 61 


LABRADOR-TEA 


Ledum groenlandicum Oeder 


Who that has traveled by the Canadian Pacific Railway in June, 
along the north shore of Lake Superior and across the boggy country 
traversed by that railroad, has not noticed the masses of low bushes 
covered with feathery heads of white flowers? When the mountains 
ate reached we still find the shrub growing luxuriantly in full sun- 
shine or adapting itself to more shaded situations, provided the ground 
is sufficiently wet. The margins of the leaves are rolled, and their 
under surface is coveted with brown wool. 

The leaves have an aromatic fragrance, and were used by the early 
settlers as a substitute for tea, but the beverage is rather too much like 
turpentine to be palatable. 

Labradot-tea is one of the members of the Heath Family and 1s 
at home in northern regions. During the glacial period it probably 
sutvived near the margins of the ice sheets, and when these melted 
back, followed them closely and became widespread in the glaciated 
territory, wherever acid soils developed. It now grows from the high- 
lands of New Jetsey northward and westward far into the Rocky 
Mountains and the Arctic regions. It was in fact given the specific 
name groenlandicum because it was first discovered in Greenland. 

The specimen sketched came from the White Mountains in New 
Hampshite. 


PLATE 62 


NORTHERN BEDSTRAW 


Galium boreale Linnaeus 


In many parts of North America northern bedstraw 1s a familiar 
plant. Although essentially northern in its distribution, as its name 
implies, it is not an Arctic plant, but seems to thrive best in regions 
of only moderately cold climate. In the central and southern Rockies 
it is abundant at middle and high altitudes, but farther north it 
frequents the foothills, extending out upon the plains. The plant 
sometimes forms dense clumps which afford a bouquet of feathery 
white flower sprays that ate delicately scented. In the Rockies the 
name wild heliotrope is occasionally applied to the plant, although 
its fragrance is scarcely suggestive of our garden heliotrope. 

Northern bedstraw grows in a great variety of situations, on open 
banks among rocks and grasses, in aspen thickets, or along streams, 
whete the abundant moisture develops luxuriant plants that are 
sometimes two feet high. The species ranges from Pennsylvania, 
Missouri, and southern California, northward over the greater part of 
Canada and Alaska, and is widely distributed also in northern Europe 
and Asia. 

This plant is one of a large group of the Madder Family, some 
members of which produce, in their roots, a red or purple dye. Most 
of our American bedstraws ate unattractive plants, with weak rough 
stems and insignificant flowers. 

The sketch was made from a specimen found near Banff, Alberta, 
Canada. 


PLATE 63 


BRONZEBELLS 


Stenanthium occidentale Gray 


Bronzebells is so delicate and graceful a lily, and has such a modest 
coloring of green and dark maroon, that it is almost hidden among 
the vegetation of the moist rich woods, where it prefers to grow. 
Flowering in company with Rocky Mountain rhododendron and 
menziesia, it is always a delight to the lover of the beautiful who 
has eyes to see the variety in nature’s handiwork, and will search for 
her hidden treasutes. 

Bronzebells ranges from Montana and Oregon to Alberta and 
British Columbia. 

The specimen sketched was obtained in the Yoho Valley, ten 
miles from Field, British Columbia, at an altitude of 4,500 feet. 


PLATE 64 


ROUNDLEAF ORCHIS 
Orchis rotundifolza Pursh 


The roundleaf orchis loves the wet shores of alpine lakes and 
frequently grows in sphagnum moss along the borders of mountain 
brooks in partially shaded, wet places. Where conditions ate favorable 
it occurs in abundance, though often overlooked by the flower lover 
because of larger and tanker plants surrounding it. The single rounded 
leaf is a distinguishing characteristic, and the sweet scent of the 
flowets is so pervasive that 1t sometimes attracts attention before the 
bloom 1s discovered. Except for a single Alaskan species, it is the only 
American member of a group tepresented in Europe and Asia by 
eighty species or more. 

The roundleaf orchis is a plant of northern range and is not known 
to grow south of the limits reached by the ice sheets of the glacial 
period. It must have survived close to the edge of the ice, and 
migtated back rapidly when this retreated. Although it died out from 
the places where it survived glaciation, 1t has subsequently spread 
across the continent, from northern Maine to British Columbia and 
northward to Greenland and Alaska. 

The specimen sketched grew at Emerald Lake, seven miles from 
Field, British Columbia, at an altitude of 3,800 feet. 


PLATE 65 


PRICKLY CURRANT 


Ribes lacustre (Persoon) Poiret 


The prickly currant is a beautiful bush when in bloom. Its graceful 
branches are then ornamented with dainty racemes of yellowish flow- 
ets, shaded with red, and the delicate green leaves are of a tint best 
suited to show them off to perfection. When growing on asteep slope, 
with full exposure to the sun, the plant is so pleasing that one wonders 
why it has not been transplanted to cultivated gardens. 

Prickly currant is found from Pennsylvania to Newfoundland and 
from California to Alaska. 

The specimen sketched was collected on the slopes of Mt. Wapta, 
ten miles by trail from Field, British Columbia, at an altitude of 7,000 
feet. 


PLATE 66 


PRICKLY CURRANT 
Ribes lacustre (Persoon) Poiret 


FRUIT OF PLATE 66 


Though never very abundant, the prickly currant is found in some 
tegions of the Rocky Mountains in sufficient quantity to furnish a 
delightful dish. When stewed and eaten with venison or wild mut- 
ton, it makes a deliciously spicy sauce. When raw, the berries are rather 
sour, and are eaten only for want of something better. 

Prickly currant may be found from Pennsylvania to Newfoundland 
and from California to Alaska. 

The specimen sketched was obtained near Glacier Lake, on the 
headwaters of the Saskatchewan River, fifty miles north of Lake 
Louise, British Columbia, at an altitude of 6,000 feet. 


PLATE 67 


GLACIERLILY 


Erythronium grandiflorum Pursh 


The glacierlily seems to radiate the spirit of the high places, and with 
bright sunshine and pure air helps to entice the lover of nature to the 
mountain tops. Along the edges of the melting snow the pointed, 
green, daggerlike leaves push upward, often through the snow itself, 
and soon the flower bursts into bloom, exhaling a delicious fragrance 
quite distinct from any other we experienced in the mountains. Car- 
peting the ground with gold, the plant may be found even in mid- 
summer, along with springbeauties, yellow violets, and buttercups, 
whete the spring avalanches have lodged their load of snow and thus 
held the early flowers in cold storage. The name avalanche lily is often 
applied to it because of this fact. At lower altitudes it grows in 
gteater numbers and with longer stems, but always with the same 
lovely coloring of brilliant green and gold. It is rarely found below an 
elevation of 4,000 feet. 

The glacierlily is evidently adapted to grow in regions of heavy 
snowfall, and no doubt survived the glacial period close to the edge of 
the ice from Wyoming to Washington, having since pushed north- 
watd into the mountains of British Columbia and Alberta. 

The specimen sketched was obtained on the slopes of Mt. Wapta, 
above Emerald Lake near Field, in the Canadian Rockies, at an altitude 
of 6,000 feet. 


PLATE 68 


BALSAMROOT 


Balsamorhiza sagittata (Pursh) Nuttall 


Wherever it is found, balsamroot is a striking plant. The arrow- 
shaped leaves, blue-green on the upper surface and white on the under 
side, ate borne on stalks five ot six inches long, above which the 
handsome yellow flowets are poised on still longer stems. When in 
bloom these plants brighten whole mountain sides with gold. The 
plant prefers moist situations on partially shaded, steep slopes, but in 
the lower valleys it frequents the borders of swampy land, among 
coarse grass and alder and willow bushes. The hotses love to feed upon 
it, and will never pass a fine clump in perfection of leaf and bloom, 
unless urged on. The large fleshy roots are eaten by the Indians, and in 
Utah they are commonly called Mormon biscuit, because of their use 
by the early immigrants in times of scarcity. 

Balsamroot is distributed from Colorado and California to British 
Columbia and South Dakota. 

The specimen sketched was obtained near Radium Hot Springs, 
British Columbia, at an altitude of 3,500 feet. 


PLATE 69 


SILVERBERRY 


Elaeagnus commutata Bernhardi 


After crossing the plains and coming into the foothill country, the 
traveler will observe many thickets of silvery-gray shrubs. In June, 
on approaching these clumps he is greeted by the peculiar sweet 
scent of the greenish funnel-shaped bells, with yellow petals, that 
hang from the under sides of the branches. The leaves, when exam- 
ined under a lens, are seen to be covered with silvery scales. Similar 
scales covering the fruit have given the plant the name silverberry. 
It is nearly related to the buffaloberry, and often grows with it. Both 
are members of the group of plants known as the Oleaster Family, 
which is considered by botanists to belong in the same order as the 
loosestrifes and evening primroses. 

Silverberry is found from Quebec to Minnesota and from Utah 
to the Yukon. 

The specimen sketched was collected near Ghost Rivet, twenty- 
five miles northeast of Banff, Alberta, at an altitude of 4,000 feet. 


PLATE 70 


SILVERBERRY 


Elaeagnus commutata Bernhard 


FRUIT OF PLATE 70 


We had known the silverberry for yeats and had enjoyed its sweet 
fragrance, but had never seen fruit on the bushes until one occasion 
when we wete traveling down the Kootenai River Valley, in the be- 
ginning of September. Here all the plants were growing in great per- 
fection, and in riding across a flat, through which a mountain stream 
meandered, we came actoss some superb silverberry bushes, which 
wete higher than our horses’ heads and loaded with fruit. They were 
so beautiful that we carried a great bunch of them back to camp, tied 
to the pommel of the saddle. Since then we have learned that the 
berries are, in a sense, edible, though too dry and mealy to appeal to the 
taste of most people, and so the prairie chickens and other birds ate 
allowed to enjoy them in peace, throughout their broad range from 
Quebec to Minnesota and Utah, and north to the Yukon. 

The specimen sketched was obtained in the Kootenai River Valley, 
British Columbia, at an altitude of 3,000 feet.

TWINLEAF 


Jeffersonia diphylla (Linnaeus) Persoon 


Jeffersonia, commonly called twinleaf, is one of the earliest of 
spring flowers. It blooms before the leaves are fully developed, and 
is somewhat like a bloodroot in appearance. The long-stemmed leaf 
blades ate parted nearly to the base, and as they are blown about by 
the wind, remind one of a group of green butterflies, though they 
lose this resemblance when fully developed, for they are then rather 
stiff, This plant, which was named for Thomas Jefferson, can be 
easily cultivated in a wildflower garden under the same conditions 
that will render the bloodroot happy 

Jeffersonia is most abundant west of the Appalachian Mountains, 
from Tennessee northward to Minnesota, Ontario, and central New 
York; locally, however, it has crossed the mountain barrier and pushed 
down the river valleys, notably along the Potomac River in Virginia 
and Maryland. 

The sketch was made from a beautiful clump growing on Plum- 
mets Island in the Potomac River near Washington, District of 
Columbia. 


PLATE 72 


IVORY BANEBERRY 


Actaea arguta Nuttall 


Ivory baneberry is a white-fruited form of the red-fruited western 
baneberty, Actaea arguta. \t prefers shady situations, near the borders 
of mountain streams, where the soil is rich and the air damp. The 
flowers, which have a sweet, sickish odor, appear in spring in racemes 
two inches long at the ends of the slender stems. The white petals and 
sepals soon fall, and the raceme lengthens. When the berries develop 
and become heavy, the stems beating them appear almost too weak to 
catty the load, and the fruits soon drop when ripe. The berries are said 
to be poisonous, like the seeds of many other members of the But- 
tercup Family, to which the plant belongs. 

Ivory baneberty is found from Utah and Colorado to Alberta and 
British Columbia. 

The specimen sketched was collected near Vermilion Pass on the 
motor road between Banff and the Columbia River Valley, at an alti- 
tude of 4,000 feet. 


PLATE 73 


PINK MOUNTAINHEATHER 


Phyllodoce empetriformis (Smith) Don 


The mountainheathers of the Canadian Rockies are an inspiration 
and a delight to those who climb to the higher places. They are found 
near tree line and on the bare slopes just above it, and cover the moun- 
tain sides with their deep green foliage. In blossom time they make a 
wonderful carpet of color—pink, ted, and white. Among them all, the 
pink mountainheather 1s in many respects the most beautiful. 

On Burgess Pass, seven miles by trail from Field, British Columbia, 
whete this specimen was gathered at an altitude of 7,000 feet, the color- 
ing was almost like that of an India shawl. The seed-pods are deep red 
and coveted with golden dots of resin. 

Pink mountainheather ranges ftom California to Colorado and 
northward to Alaska. 


PLATE 74 


ROCKY MOUNTAIN CASSIOPE 


Cassiope mertensiana (Bongard) Don 


With the exception of the rare orchids, the Rocky Mountain 
cassiope is perhaps the most romantic of American mountain flowers. 
It is found in perfection about tree line in the Canadian Rockies, 
which is usually at an altitude of 6,500 to 7,500 feet. Here, in favor- 
able localities, it frequently forms dense, thick mats, and when in full 
bloom the plants are literally covered with delicate white bells. The 
tiny stems holding the blossoms may be either green or red, and when 
the flowers fall the seed capsules are usually red in color, becoming 
brown as the season advances. Growth in a single season is rather 
limited, and the stiff, woody stems underneath bear silent witness to 
the vicissitudes of plants at high altitudes. To the camper a bed of 
cassiope is most satisfying, for in addition to its springiness it 
possesses an elusive fragrance that persists even when the plants are 
quite dried out. The ted, pink, and white mountainheathers ate fre- 
quently found growing with the cassiope, and add color to the wild- 
flower carpet on the mountain sides. 

Rocky Mountain cassiope is to be found from Montana to northern 
California and Alaska. 

The specimen sketched was obtained at Burgess Pass near Field, 
British Columbia, Canada. 


PLATE 75 


ONE-LEAF BOG-ORCHID 


Habenaria obtusata (Putrsh) Richardson 


This orchid is exceptional in having but a single basal leaf: The 
plant grows on the mossy banks of streams or in boggy places, de- 
lighting in the peaty soil, where other members of the genus Habe- 
natia flourish. Its green color renders it inconspicuous and easily 
overlooked, especially when the larger, white, sweet-scented varieties 
are its near neighbors. | 

This species ranges from Maine, New York, and Colorado and 
northward to Newfoundland and Alaska. | 

This specimen was found at Hillsdale, eleven miles northwest of 
Banff, Alberta, at an altitude of 4,000 feet. 


PLATE 76 


BUSH CINQUEFOIL > 


Potentilla fruticosa Linnaeus 


Bush cinquefoil is one of the showiest plants of the Canadian 
Rockies, where it seems to find congenial surroundings almost evety- 
where, flourishing in alpine meadows or on mountain slopes,and some- 
times at high elevations, struggling against the mountain winds and 
other advetse conditions to obtain a foothold. In midsummer it is 
covered with clear yellow flowers, which appear to greater advantage 
by reason of the silver-gray foliage that forms their background. In 
moist limestone soils in New England it is classed as a weed, because of © 
its invasion of idle fields and pastutes. 

This member of the Rose Family is found from California, New 
Mexico, and New Jetsey northward to Alaska, central Canada, and 
Labrador, as well as in Europe and Asia. 

The specimen sketched was collected on the trail below Burgess 
Pass, six miles from Field, British Columbia, at an altitude of 5,000 feet.
