26 PHLOX ORDER 
and deep red are the commonest colors. The blossoms are clustered 
along the slender stems which are 2-4 ft. tall. The plants are widely 
distributed on plains, foothills and open places in the mountains at 
6000-10000 ft. and they bloom throughout the summer. The hum- 
ming-bird is a regular visitor of this flower for the sake of its nectar. 
In fact, the latter can be secured only by humming-birds and butter- 
flies because of the length of the tube. In Indian legend, Ni nectar 
of the Trumpet Phlox was the drink of the wild dove. 
NECTAR CuP POLEMONIUM SPECIOSUM 
Plate 19, fig. 5 
The fragrant pale blue flowers of the Nectar Cup are hidden away 
on the highest peaks of Colorado at 12000-14000 ft. They grow in 
dense heads at the tips of stems about a foot tall and bloom in mid- 
summer. The name refers to the abundant honey at the base of the 
corolla tube. 
Jacos’s LADDER POLEMONIUM PULCHELLUM 
Plate 19, fig. 6 
Jacob’s Ladder doubtless receives its‘name from the ladder-like 
leaves. The flowers are delicately blue with white tubes and are clus- 
tered on giaceful stems a foot tall or less. They may be found in 
spruce forests on the mountains at 8000-14000 ft. and bloom in sum- 
mer, often so abundantly as to form a blue carpet on the forest floor. 
Tiny TRUMPET  COLLOMIA LINEARIS 
Plate 19, fig. 7 
The tiny white to reddish flowers of this plant may easily be over- 
looked on account of their size. They are grouped on stems which 
vary from a few inches to about 3 ft. in height, and grow in dry and 
sandy soil at 4000-9000 ft. They come into bloom in the spring and 
blossom throughout the summer.
