202 SMITH: STUDIES IN THE GENUS LUPINUS 
tracted into an acute apex and an ill-defined slender claw, wings 
12 x6mm., non-ciliate, keel nearly straight: mature seed not seen. 
British CoLtumMBIA. Vancouver Island: sea cliffs, Beacon 
Hill, 4 July, 1889, J. Macoun 21 (Tyre, US 20837; type-duplicates, 
T, G); Aug., 1873, H. Edwards (NY); cliffs by sea, Beacon Hill 
Park, Victoria, A. J. Pineo (UC). 
WaAsHINGTON. Island County: Whidby Island, N. L. Gard- 
ner (UC). 
While this form and the var. austrocollium may not be properly 
included in L. densiflorus, they certainly are less closely related to 
typical L. microcarpus; and var. scopulorum is certainly specifically 
distinct from its nearest neighbor, the Yakima Valley form I have 
called var. fluviatilis of L. subvexus. 
Scopulorum, ‘‘of the cliffs,” is the genitive plural of scopulus. 
More extended and much more careful field study of these 
forms should contribute both taxonomic and ecological data. 
Interesting genetical data should also be obtainable from garden 
cultures; but one would have to devise first a suitable method of 
treating the seed in order to obtain proper germination, for the 
“‘hard-seed problem’’ would probably be the first stumbling stone 
to success in cultural studies—at least that has been my experience. 
The collection and identification of seeds should be pursued 
with especial care, as one may often carelessly, though uninten- 
tionally, mix in collecting, at one time and locality, seed of more 
than one species or variety. 
To the many friends who have generously assisted me in many 
different ways my full appreciation is herewith acknowledged. 
Listing of all of them will not be attempted here; but I cannot 
refrain from mentioning Drs. B. L. Robinson, H. M. Hall, and 
P. A. Rydberg, Professors H. H. Bartlett and L. R. Abrams, and 
Mr. Sidney F. Blake. Mr. Blake, while in England, looked up the 
old material of L. microcarpus, L. densiflorus, etc., and gave me 
certain valuable information.
