EVENING PRIMROSE FAMILY. Onagraceae. 
deep-red and the flowers form a handsomer cluster, 
shorter than the last, with leafy bracts, each flower from 
one to over two inches across, with reddish-pink sepals, 
deep-red outside, and magenta petals veined with deeper 
color, sometimes notched, one petal longer than the 
others; the anthers purplish; the pistil drooping and pur- 
plish, with a smooth style. This plant is also covered with 
tufts of white down when gone to seed. The contrasting 
purples and reds of the flowers give a very vivid effect, 
set off by the bluish-green foliage, especially when growing 
among the gray rocks of moraines, watered by icy glacier 
streams. It reaches an altitude of ten thousand feet, 
growing in the East and in Europe and Asia. 
- There are many kinds of Epilobium, differing from 
Chamaenerion chiefly in the calyx-tube, which is prolonged 
beyond the ovary. 
Willow Herb A perennial, not especially pretty, with 
Epilobium a stout, reddish stem, from one to three 
Franciscanum feet tall, slightly downy above, and dull 
Pink green leaves, mostly smooth and the 
Spring 
lower ones opposite. The flowers are 
less than half an inch across, with bright 
or pale, purplish-pink petals, deeply notched and not 
spreading. This grows in wet spots around San Francisco. 
There are several kinds of Gayophytum; differing from 
Epilobium in the capsule and seeds, and easily distin- 
guished from them by the hairy buds; leaves alternate, 
long, narrow, and toothless; flowers small; petals four, 
white or pink, with very short claws; stamens, with 
swinging anthers, eight, four shorter and usually sterile; 
capsule club-shaped. The species are difficult to dis- 
tinguish, because of the smallness of the flowers.
