FLORA OF MOUNT RAINIER NATIONAL PARK. 
pipe, while the plant having only one flower is called the one-flowered 
Indian pipe. The one-flowered species grows in dense clusters, 
while the other has not this tendency. 
The Allotropa , or barber’s pole (fig. 2), is a beautiful red and white 
striped plant confined to the forest of the Pacific coast. It is, per¬ 
haps, the oddest of this strange group, because of its bright colors. 
The pine sap, Pterospora andromedea (fig. 2), may be recognized 
by its reddish-brown stem, 3 or 4 feet high, without leaves, and by 
the numerous globular flowers arranged along the upper part of the 
stem. This plant, like the Indian pipe, has a wide range, extending 
across the continent. Locally it extends from about 1,000 feet above 
sea level to about 3,800 feet. The rarest of this leafless group is 
Hemitomes congestum (fig. 2). It is so rare that it has no common 
name. Like the one-flowered Indian pipe, it grows in dense clusters. 
The writer saw one bunch collected below the park entrance that 
filled an ordinary milk pan. Not only do these plants grow in dense 
masses but the flowers on each plant are also massed together, as the 
specific name indicates. In its prime it is a beautiful rose-pink or 
sometimes nearly white, but with age it turns black like nearly all 
of the Indian pipe family. It extends from near sea level to an 
altitude of about 3,200 feet. On the southeast slope of Mount 
Angeles, near an old deserted cabin, the writer found the five species 
shown on figure 2. The plants were collected and placed hurriedly 
on an old table and photographed with the side of the log cabin for 
a background. 
Closely related to this leafless group is the Pyrola or wintergreen 
family, which is well represented and seems to be a connecting link 
between the Indian pipe family and that of the heath or heather 
family. In the old textbooks all three families are included in the 
heath family. The name pyrola means a little pear, from the fact 
that the thick shining evergreen leaves resemble those of a pear tree. 
These species are easily recognized in the dense forest. Pyrola 
secunda is known at once by its one-sided raceme of small greenish 
flowers or seed-pods. The wintergreen of commerce is not obtained 
from any of the western species, but from the false wintergreen or 
checkerberry of the East. This plant is more abundant in the second 
zone. Pyrola aphylla , as the specific name indicates without leaves, 
has small bracts. Pyrola bracteata has rather large round or elliptical 
leaves in a rosette with flowers in a raceme. This plant resembles 
the eastern “shin-leaf.” Still another, Pyrola picta, might be added. 
This may be recognized by the white spots or streaks in its rather 
long leaves. Moneses unijlora is a beautiful little plant of this small 
family. It may be known from the pyrolas by its single waxy 
flower. Its generic name signifies “delight.” It is needless to add
