is not nearly so abundant as its dwarf congener A. androsemifolium 
of the valley borders and walls. 
Of the milkweeds, Asclepias speciosa and Gomphocarpus cordi- 
folius are abundant, especially the latter. 
The most beautiful of our species of Canchalagua, Lrythrea 
_ venusta, has been brought from the lower end of the valley. 
Two blue gentians, Gentiana Newberryi and G. calycosa, are 
found in high meadows—the latter especially, near the Anderson 
trail to the South Dome. 
The spreading Polemonium (P. humile) grows about the heights 
on shady and moist hillsides, the more showy P. ceruleum is less 
frequent. 
Phlox Douglasii abounds in tufts of white, lavender and various 
Shades of pink, on nearly all the heights, particularly about Sentinel 
- Dome. 
Gilia abounds in and about the valley, as nearly everywhere in 
‘California. The yellow-flowered G. grandiflora grows at the lower 
end of the valley. G. tenella, G. ciliata and G. heterophylla, are 
‘common. The diffuse and slender G. capil/aris grows near the 
upper end of Indian Cafion and G. aggregata and G. pungens, the 
latter of as many hues as Phlox Douglasii, are found on the heights. 
_ Draperia systyla grows at moderate elevations on the walls of the 
lower end of the valley ; yerba santa (Zriodictyon glutinosum) at 
lower elevations, and Mama Lodéii on the heights. The low Hes- 
‘perochiron Californicus grows above Glacier Point. Phacelia nam- 
atoides grows near the summit at the lower end of the valley. P. 
hydrophylloides about the heights and Nemophila parviflora is com-

Mertensia Sibrica grows on the heights and Echinospermum 
diffusum and Plagiobothrys Torreyz, which stains a bright blue, are 
frequent. 
The paint-brush ( Castlleia linariefolia) grows in red-tipped 
clumps about the heights ; Cod/ins¢a Torreyz is found on the higher 
slopes at the foot of the valley, and the pale C. ¢zctoria frequents 
shady banks. 
Mimulus luteus is found about the borders of springs and small 
streams; JZ, primuloides sends its slender scape-like stems from the 
‘borders of the damp meadows ; JZ. Fremonti and M. Torrey? grow 
on rocky slopes near the foot of the valley ; JZ Lewisiz, from the
