180 SMITH: STUDIES IN THE GENUS LUPINUS 
6g. Lupinus densiflorus glareosus (Elmer) comb. nov. [F1G. 24.] 
Lupinus glareosus Elmer, Bot. Gaz. 39:53. 1905. 
I quote from Elmer’s description, as follows: 
An almost acaulescent annual, 3s 5 dm. high, somewhat succulent though readily 
outer ones curved upwards from the middle . . . leaflets 10 . . . sparsely pubescent 
on both sides, soft and fleshy . . . the older ones with a very peculiar dead scarious 
pany spikes cylindrical . . . 10-15 cm. long, erect and exceeding the leaves 
wers. in whorls of 5, upon short pubescent pedicels . . . calyx . . . pubescent; 
ae lip rather broad, 7 mm. long, obtuse, 3-nerved; upper one thinner, 3 mm. long, 
notched; banner broadly elliptic, 12 mm. lon keel at least 12 mm. long, fal-

It is wholly confined to dry bteiels soil along water courses, hence its name. 
Fic. LUPINUS DENSIFLORUS GLAREOSUS (Elmer) C. P. Smith. 1. A. D. E. 
Elmer ar (US 465791); 2. Abrams & McGregor 262 (US 613146). 
I consider this one of the most extreme variations of L. densi- 
florus, and I would have upheld it as a species but for the evidence 
presented by Abrams & McGregor’s collection listed below. The 
following characters should also be mentioned. 
Foliage blackening in drying; verticils crowded or distinct, six 
to twelve or fewer; flowers spreading in anthesis, becoming secund 
later, 13-14 mm. ‘beng: calyx bracteolate, 6.5-8 mm. long, very 
shortly and almost sparsely appressed-pubescent, upper lip a little 
an I mm. long and cleft, or 2-3 mm. long and emarginate, 
lower lip entire and acute or minutely fer ba about 3 mm.
