This species might well be viewed as a connecting link between 
the Pusilli and the Microcarpi. Its possession of verticillate 
flowers is my only excuse for referring to it in this paper. Forms 
of L. subvexus transmontanus, of northern California and Oregon, 
are the only specimens of the Microcarpi that have already been, 
and may yet be expected to be, confused with L. malacophyllus. 
Seeds in my collection, collected by Heller, from about Reno, are 
from pale flesh-color to dark reddish.

[Fics. 2, 3.] 
The original description is as follows: 
Lupinus microcarpus; foliis digitatis, calycibus verticillatis in ane Pap AS 
labio rate emarginato inferiore bifido ter breviore, leguminibus rhombeis hir- 
sutis disperm 
Descr ea branched. Leaves aaa cuiated 9-10, lanceolate, hairy on 
the under surface, smooth on the petioles twice the length of the 
leaflets, pubescent. Stipules ae ney go ncle terminal. Flowers blue, in a 
verticillate ane six-flow red. Bracts small, hairy. Calyx Wace late 
( which are asta from the calyxes, are to be called the appendices) 
bilabiate; Mie pat much the shortest, emarginate; lower lip bifid. aun oblong. 
g the vexillum arina monopetalous, sharp-pointed. Anthers 10, 
five Pasi pe five hac. Style the length of the stamens. Stigma capitate. 
Legume small, rhomb-shaped, mucronate by the persistent style, hairy; seeds two, 
variegated with black lines and dots. 
This species of Lupin is a native of Chili. It has not, we believe, been heretofore 
described; and differs from all the known species by its small two-seeded We 
regret however that we did not receive these in time enough to be added to me en- 
graving.
