This paper completes my review of the annual and biennial 
lupines of North America, exclusive of Southern Mexico and 
southward. The next parer, therefore, will probably be con- 
cerned with scme one of the several perennial groups that have 
already received considerable of my attention. It seems appro- 
naa ae to append here notes concerning certain forms, as 
follow 
Sages microcarpus scopulorum, comb. nov. 
Lupinus densiflorus scopulorum C. P. Smith, Bull. Torr. Club 
45: 201. 1918,—as to Vancouver Island plants. 
When this variety was published I made certain reservations, 
expressed in the following words: 
While this form and var. austrocollinum may not be properly 
included in L. densiflorus, they certainly are less closely related 
to typical L. microcarpus. 
In July, 1922, I had the pleasure of visiting Victoria, Van- 
couver Island, and studying this plant in its natural home and 
type locality. It was abundant, in full bloom, fruit, and seed, 
and I followed it along the seacoast cliffs, throughout the area 
occupied, looking for variations. Much to my surprise, I found 
the flowers to be constantly and conspicuously suberect or as- 
cending in both the axial racemes and in all those of the branches. 
The petals are decidedly yellow in the fresh flowers, the fruits 
typical of the group, ovate, 10-12 mm. long, secund, the seeds 
dull, dark brown, unmarked, 5 X 4mm. The plants are widely 
branched at the base, often also above. 
Thus I was able to settle, in my own mind, all doubts as to 
the proper classification of the Victoria elements of my original 
treatment, the phrase, “floribus ad anthesin et postea panden-
