EVENING PRIMROSE FAMILY. Onagraceae. 
rows of spines in stars along the ridges, and ornamented 
during May and June with handsome, large, whitish, wax- 
like flowers, very perfect in form, opening in the daytime, 
blooming most abundantly on the sunny side of the plant 
and remaining open but a short time. Woodpeckers 
often make holes for nests in the branches, which are used 
afterwards by a little native owl, the smallest kind in the 
world, and by honey-bees, and these holes often lead to 
decay and to the ultimate death of the tree. The fruits, 
with: crimson fiesh and black seeds, are valued by the 
Papago Indians for food, and mature in enormous quan- 
tities in midsummer, but birds eat up many of the seeds 
and of the millions reaching the ground only a very few 
germinate and develop into odd, little round plants, a few 
inches high, often eaten by some animal before they become 
sufficiently prickly for protection. 
EVENING PRIMROSE FAMILY. Onagraceae. 
A large family, widely distributed, most abundant in 
America; herbs, with no stipules; flowers usually perfect, 
their parts usually in fours; calyx-tube attached to the 
usually four-celled, inferior ovary and usually prolonged 
beyond it; stamens four or eight, inserted with the petals, 
on the throat of the calyx-tube, or on a disk; style single 
with a four-lobed or round-headed stigma; fruit usually a 
four-celled capsule, containing small seeds ora nut. The 
flowers are generally showy and many are cultivated. 
This is the only kind of Eulobus. It 
Eulob 
eee would be a pretty plant, if more flowers 
Yellow were out at one time and if they did not 
Spring close so soon. The smooth, hollow, loosely- 
Sa ye branching stem is from one to three feet 
tall, with a ‘‘bloom,”’ the leaves are smooth, rather light, 
dull-green, and the buds are erect. The flowers are about 
three-quarters of an inch across, with a very short calyx- 
tube, light-yellow petais, fading to reddish-pink, eight 
stamens, four of them smaller and shorter, and the light- 
green stigma with a round top. The slender pods are 
three inches long, smooth, cylindrical, and turning stiffly 
down, with many seeds. This grows in mountain canyons.
