FLORA OF THE CASCADES 
163 
Lonicera involucrata Banks. In a small canyon at the eastern 
edge of the lava fields. 
Lonicera co.erulea L. A small colony at the edge of a meadow, 
Sisters. 
Sambucus callicarpa Greene. A few specimens in the clefts of 
the rocks at the edge of the lava fields. 
Valeriana sitchensis Bong. Plentiful in a small canyon at the 
edge of the lava fields. The subspecies scouleri (Ryd.) 
Piper, is found regularly in the Canadian and often in the 
Transition, while the type is Hudsonian. Our form is quite 
typical, and is therefore out of its normal range. 
Ptiloria virgata (Benth.) Greene. Infrequent; in dry ground. 
Sisters. 
Agoseris glauca (Nutt.) Greene. Rather scarce, in damp mead- 
ows, Sisters. 
Agoseris Jieterophylla normalis Piper. Common in moderately 
dry ground, Sisters and Bend. 
Hieracium griseum Ryd. Frequent in rather dry ground. Sis- 
ters. 
Chrysothamnus puberulus Greene. High, dry ground. Sisters 
and Bend, more common at the latter place. This seems 
much to the westward of the regular range of the species. 
Chrysothamnus viscidiflorus (Hook.) Nutt. High dry ground, 
plentiful at Sisters, very abundant at Bend. 
Chrysothamnus nauseosus (Pall.) Britt. With the preceding and 
equally common. The two species are known as Rabbit 
brush”, and in the Upper Sonoran zone are second only 
to the sagebrush in abundance. * 
Solidago missouriensis Nutt. Frequent in moderately dry 
ground. 
Townsendia florifer (Hook.) Gray. Frequent in dry ground, 
Sisters. 
Erigeron poliospermus Gray. In dry ground. Sisters. Only one 
specimen found. ’ 
Erigeron linearis (Hook.) Piper. Frequent in very dry ground, 
Sisters and Bend. 
Erigeron armeriaefolius Turez. A high altitude species of the 
Blue and Rocky mountains, and the Sierras, seemingly not 
hitherto known from th6 Cascade region.
