47. LUPINUS. Tvurn. ; Gfertn. fr. I. 150 ; J. G. Agardh, synop, 

 gen. Lupin. (1835.) 

 Calyx deeply bilabiate, often 2-bracteolate ; the upper lip 2-fleft or 

 toothed, or rarely entire ; the lower entire or 3-toothed. Vexilluni with the 

 sides reflexed : wings foveolate-plieale towards the base, united at the sum- 

 mit : keel falcate, acmuinate. Stamens monadclplious ; the shealli entire : 

 alternate filaments longer : the 5 anthers opposite the sepals oblong and earlier 

 matured ; those opposite the petals roundish or reniform and later. Stigma 

 bearded. Legume coriaceous, somewhat oblong, more or less compressed, 

 often torulose or intercepted with cellular partitions. Cotyledons fleshy. — 

 Herbaceous or rarel}'' shrubby plants. Leaves palmately 5-15-foliolate, or 

 rarely reduced to a single leaflet. Stipides eidier free or adnate to the 

 petiole. Flowers in terminal racemes or spikes. — Lupine. 



§ 1. Annual : leaflets several : legumes more or less interrupted or constricted 

 between the seeds, dehiscent the following year. 



* Legumes intercepted with cellular partitions between the seeds : cotyledons 

 thick and large, sessile or nearly so in germination : primordial leaves 

 evident in the seed, opposite. Agardh. 



t Stena somewhat naked : spike elongated, with numerous flowers in regular 

 whorls : seeds elliptical, compressed, smooth. Agardh. 



1. L. Menziesii (Agardh) : flowers verticellate in a very long spike, pedi- 

 cellate ; die pedicels about the length of the somewhat setaceous persistent 

 bracts ; calyx without bracteoles, the lips entire ; the upper one scarious, 

 about half the length of the lower herbaceous one. Agardh ! syn. gen. Lu- 

 pin. jJ' 2; Hook. S^' Am. ! hot. Bccchey, suppl. p. 335. 



California, Douglas! — Silky-pu])escent. Peduncle elongated. Leaflets 

 obovate-S])atulate, nearly half the length of the petiole, the apex mucronate 

 and recurved. Whorls distant. Calyx pubescent. Corolla yellow. 



2. L. microcarpus (Sims) : flowers verticillate in an elongated spike, 

 nearly sessile ; bracts subulate, persistent ; about the length of the somewhat 

 2-cleft upjjer lip of the ebracteolate cah'x, and about half the length of the 3- 

 toothed lower lip. Agardh. — Sims, hot. mag. t. 2413 ; DC. prodr. 2. p. 408 ;

California, Douglas ! — This species is a native of Chili, and Agardh re- 

 marks that he cannot distinguish the Calilornian specimens, except that the 

 flowers are jierhaps a little smaller and the petioles longer. Leaves clustered 

 at the base of the stem. Stem about a foot high, and with the ])etiolcs and 

 lower surface of the leaves, a little -sillous. Calj-x densely villous. Corolla 

 puriilish-blue : vexillum yellowish in the centre, with purple spots. Le- 

 gume 2-seeded. 



3. L. densiflorus (Benth.) : flowers verticillate in a dense spike, subses- 

 sile ; bracts persistent, reflexed, about the length of the corolla ; calyx 

 ebracteolate ; the upper lip emarginate, half the length of the very villous 3- 

 toothed lower one. Agardh. — Benth.! in hort. trans, {n. ser.) 1. p. 409 ;
