ROSE FAMILY. Rosaceae. 
There are several kinds of Cowania. 
bine nee Altitude and soil make a great differ- 
Gowdain ence in the beauty of this shrub. On the 
Stansburiana rocky rim of the Grand Canyon it is from 
Yellow four to eight feet high, picturesquely 
Spring, summer 
nt gnarled and twisted, but stunted looking, 
the gray bark hanging off the crooked 
branches and thick, distorted trunk in untidy shreds, the 
flowers pale, scanty, and but faintly scented. Halfway 
down Bright Angel trail it is a glorious thing, full of color 
and fragrance, about twelve feet high, luxuriant and 
healthy-looking. The small, leathery, evergreen leaves, 
crowded in bunches along the branches, are glossy and rich 
in color, setting off the light yellow flowers, with golden 
centers, which form long wands of bloom. The upper 
branches are clustered closely their whole length with 
‘blossoms, and when the wind sways the flowering branches 
to and fro they exhale an exquisite fragrance like orange 
flowers. The bloom is at its best in the Canyon in May, 
but there are still some lingering flowers in August. The 
calyx is top-shaped, with the petals and the two rows of 
numerous stamens on the throat of the tube. The pistils, 
from five to twelve, are densely woolly. The akenes have 
pale, silky-hairy tails, two inches or more in length, sug- 
gesting gone-to-seed Clematis. For some occult reason 
this shrub is called Quinine Bush at the Grand Canyon. 
There are two kinds of Aruncus, resembling Spiraea; 
with small white flowers, the stamens and pistils in separate 
flowers on different plants. Aruncus is a word used by 
Pliny to designate a goat’s beard. 
pias ie high, with somewhat branching stems and 
(Spiraea aruncus) smooth leaves, thin in texture. The 
White minute, cream-white flowers are crowded 
ceo 8 pbcee: closely along the many sprays which make 
up the very loose cluster, which is about a 
foot long, the effect of the whole being exceedingly airy 
and graceful and in fine contrast to the handsome foliage. 
This grows in mountain woods, across the continent and 
in Europe and Asia.
