simpler and more dwarf purple-stemmed plants of north- 
west Arctic America and the adjacent islands, which have 
been variously referred to domesticus, longifolius, and 
arcticus. They have commonly rather thick and succulent 
stems and subelliptical leaves, but all that Ihave seen are too 
immature for satisfactory determination with my present 
knowledge of the genus. — Specimens referred here doubt-

ger, 1882, 12, and 1883, 50; Dall, 1872; Muir, 1881, 125 
and 217 (the last from Siberia); Murdoch, 1883; and Str. 
Corwin, 1884.—A very similar plant in hb. California 
Academy from Golovnin Bay ( Yemans, 1884).

erect, stout, subsimple; leaves acid, usually quite wavy, 
ample or the lowest very large, ovate-lanceolate and ellip-

principal veins often slightly papillate below; panicle 
strict, very dense in fruit, with few small leaves; whorls 
compact and approximate; pedicels nearly twice as long 
as the fruit, tumidly jointed near the base or below the
