 Var. NANUS (Hook.), R. domesticus, /9. nanus, Hook., 

 Bot. Bor. Amer. ii. (1840), 129, probably comprises the 

 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 I have seen are too 

 immature for satisfactory determination with my present 

 knowledge of the genus. Specimens referred here doubt- 

 fully: Wright, on Ringgold and Rodgers Exped. ; Stejne- 

 ger, 1882, 12, and 1883, 50; Doll, 1872; Muir, 1881, 125 

 and 217 (the last from Siberia) ; Murdoch, 1883; and 8tr. 

 Corwin, 1884. A very similar plant in hb. California 

 Academy from Golovnin Bay ( Yemans, 1884). 



8. R. PATIENTIA, L. Usually about three leet high, 

 erect, stout, subsimple ; leaves acid, usually quite wavy, 

 ample or the lowest very large, ovate-lanceolate and ellip- 

 tical, acute, the base rounded or decurrently acute, the 

 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
