dant. A form with very minute flowers. 
Eriogonum compositum Dougl. Rather common in dry ground, 
Sisters. 
Eriogonum umhellatum Torr. Scarce; in very dry ground. Sis- 
ters. This form has a remarkable altitudinal range, occur- 
ring from Arid Transition to Arctic. It varies extremely 
in size, the high altitude forms, being very dwarf. Our ma- 
terial is possibly the subspecies majus Benth. 
GJiaenopodium boirys L. Frequent in damp ground along the 
Des Chutes. 
Monolepis spatulata Gray. Frequent in moist gTound near the 
Des Chutes. 
Monolepis nuttalliana (R. k S.) Greene. With the preceding, 
and about equally common.

cality. 
Silene menziesii Hook. A few specimens found in moderately

material represents a low bushy variety, with the leaves 
of the copious inflorescence greatly reduced. 
Silene sp. Frequent in very dry ground. Sisters. 
Cerastium sp. Several specimens found in rather dry ground 
at Sisters. A form resembling C. nutans Raf„ but the 
petals and pedicels too short.
