148. LATHYRUS. 



(3102.) L. Nuttallii, Watson, Proced. Amer. Acad., XII., 450. 

 L. venosus, Macoun, Cat. L, 121, in part 



Stout and tall, more or less pubescent throughout, with loose woolly 

 hairs ; stipules, semi-sagittate, rather narrow ; leaflets, 3 to 6 pairs, 

 variable, narrowly or broadly elliptical, usually acute or acutish at 

 both ends, apiculate, 1 or 2 inches long ; rachis, tendril-bearing ; 

 peduncle shorter than the leaves, few-flowered ; calyx teeth triangular, 

 acuminate, the lower somewhat larger ; petals reddish purple, 6 

 to 8 lines long ; pod, glabrous, oblong, attenuate to a very short thick 

 stipe, 1 to 1J inches long by 4 lines wide; seeds, globose, brown. Com- 

 mon in thickets in British Columbia and Vancouver Island. In Part 

 I., 121, this species was included in L. venosus, but is now separated 

 by Dr. Watson. 



155. PRUNUS. 



(573.) P. Virginiana, Linn., Var. (?). 



A form of this species, with very long deciduous sepals occurs in 

 British Columbia, extending from the Fraser Yalley northward to 

 Telegraph Creek. 



157. SPIR/EA. 



(580.) S. Douglasii, Hook. var. Menziesii, Presl ; Macoun, 

 Cat. L, 127. 



This variety is very common throughout British Columbia and 

 Vancouver Island, while the type of the species is confined to Van- 

 couver Island, as far as our knowledge of it extends. 



A variety which we refer to S. satitifoUa, was gathered at Sicamous 

 in July, 1 889. It would pass in the east for S. salicifolia, as it has a 

 large branching panicle, white flowers, and long exserted stamens. 

 So far S. salicifolia has not been found west of the Rocky Mountains, 

 but is reported from the far north. 



158. PHYSOCARPUS. (Neillia.) 



(584.) P. opulifolius, Maxim. ; Gray, Man., ed. VI., 153. (1890.)
