Usually abundant where found, especially in the Bay Region. 
As recorded by both Dr. Greene (Pittonia 1: 171. 1886) and 
myself (Muhlenbergia 6: 141. 1911), this species is the least 
conspicuous of all when in flower; yet in fruit it is more con- 
spicuous than L. bicolor. 
Just one variety do I care to characterize here. 
7b. Lupinus micranthus Congdoni, var. nov. 
Erectus 5-8 cm. altus, caulibus gracilibus pubescentibus 
pilis brevis ascendentibus; foliis paucibus, peti iolis 1-3 cm. 
fonigis, foliolis sex ad octo spathulatis 4 m “il I-I.5m 
latis utrimque pubescentibus; rac ongis, floribus 
paucibus alternis 6-7 mm. longis, bedivellig cit circa I mm is, 
petalis iis plantae typicae persimilibus; legumina seminaque non 
vidi 
Erect, 5-8 cm. tall, the slender stems pubescent with ‘short 
ascending hairs; leaves few, the petioles 1-3 cm. long, the leaflets 
4-6 mm. long by I-1.5 mm. wide, six to eight, spatulate, pubes- 
cent on both sides; raceme I-2 cm. long, flowers 6-7 mm. long, 
few and scattered, pedicels about I mm. long, petals not dif- 
ferent from those of the typical plant. 
CALIFORNIA. Tuolumne County: Big Oak Flat, Smith 
Ranch, Yosemite road, April, 1902, J. W. Congdon (TyPE, G; 
type-duplicates US 466,501 and 466,502 
Labelled, “ZL. gracilis Agardh,” and annotated, “‘n. sp.” Tat 
first freely accepted it as a new species; but after making dis- 
sections and drawings of the floral parts, came to the decision 
followed here. It is certainly an odd extreme, evidently re- 
presenting the result of a keen struggle for existence. My 
drawings are included in Fig. 94. 
The abbreviations used herein, in citing specimens, are 
explained in the list below.
