Seemingly peculiar to the valley of the Yakima River in central 
Washington. The flowers are relatively large with broad petals. 
Perhaps the strongest individual character is that the floral bracts 
are tardily or not at all reflex-withering as the flower-buds open. 
The seeds are flesh-color, mottled with a pale reddish brown, the 
hilum of the darker color. Fic. 1 illustrates abnormal specimens 
of this variety. 
Fluviatilis is Latin for 
4d. Lupinus subvexus transmontanus var. nov. [Fic. 10.| 
A var. fluviatili differt foliolis oblanceolatis plerumque acutis; 
calyce 9-11 mm. longo, sinu labii inferioris plerumque dentis 
vestigio instructo; vexillo apice angulato, 11-12 mm. longo, prope 
6 mm. lato ad basin paullatim contracto. 
Similar to var. fluviatilis, but the leaflets are usually acute at 
the apex, the floral bracts usually reflex and wither as the flower- 
buds open, the lower lip of the calyx has the vestigial median tooth, 
and the banner is evidently acute at the apex. .
