VOL. I. | Flora of Yo Semtte. 161 
The columbine ( Aguzlegia truncata) is nearly as common as in 
our coast region, the flowers rather larger. The meadow rue ( 7ha/- 
ictrum polycarpum ) is the same as the one found about San Fran- 
cisco, but the monk’s hood (Aconitum Columbianum) does not in 
our latitude approach the coast. 
The yellow water-lily ( Nuphar polysepalum ) is found in Hutchings 
Meadow, Eagle Meadow, etc. 
Dicentra formosa, DC., which is also found in the immediate 
vicinity of San Francisco, makes a much better showing than with 
us. D. uniflora Kell. the second species of Yo Semite is peculiar 
to mountainous regions. 
Among the cruciferee Avabis repanda with its rather broad falcate 
pods; Streptanthus tortuosus Kell. with rounded clasping leaves and 
purplish flowers; Chetranthus asper Ch. & Sch. with its showy head 
of deep yellow or orange, sweet-scented flowers, and the delicate 
“‘lace-pod’’ Thysanocarpus curvipes are found in all collections. 
The violets are Viola blanda, V. canina var. oxyceras, V. nuttallit, 
V. glabella and V. lobata. ; 
Of the Caryophyllaceze Szlene antirrhina, S. Californica, 5S. 
Bridgesit and S. Douglasti; Stellaria nitens, S. longipes, and SS. 
Jamesti; Arenaria congesta, and A. pungens are all that are con- 
tained in the collections. 
The widely distributed C/ayionia perfoliata is usually found in 
smaller forms with the cauline leaves not so completely united as in 
the coast form. C. exigua forms low and dense glaucous tufts with 
linear leaves, C. Chamissonis and C. parvifolia occur in wet places, 
often clinging to the crevices of dripping rocks about the falls. C. 
triphylla is found usually at considerable altitudes above the valley. 
Spraguea umbellata known as “ pussy paws’’ is abundant on the 
floor of the valley towards the lower end. Its flowers, which vary 
from nearly white to deep pink, are showy and handsome, and as it~ 
_ loves the sand, its deep biennial root might be a somewhat useful, 
and its flowers most surely a welcome addition to the flora of our 
dunes. 
Linum micranthum and the rare L. digynum are the species of our 
native flaxes found near Yo Semite. 
Geranium incisum is found in all collections. 
The Lupines of the region are not many but among them is found 
the handsomest of all the species, which was named Lupinus Stivert,
