ROSE FAMILY. Rosaceae. 



There are several kinds of Cowania. 



Altitude and soil make a great differ-

Stansburidna rocky rim of the Grand Canyon it is from 

 Yellow four to eight feet high, picturesquely 



Spring, summer rled and twiste d, but Stunted looking,

the gray bark hanging oft 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.

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.
