lineari-oblongis lanceolatisve apice obtuso vel apicnlato ; racemis brevi- 

 bus laxifloris ; dentibus calycis lato-subulatis tubo brevioribus ; legu- 

 mine gibboso-ovoideo, sutura ventrali fere recta. — California, near the 

 coast, Douglas, Fremont, Brewer. 



64. A. MACRODON. Phaca macrodon, Hook. & Arn. 1. c. Ad- 

 scendens vel erectus, villosulo-canescens, nunc glabriusculus : stipulis 

 lanceolato-subulatis discretis ; foliolis 11 - 14-jugis lineari-oblongis apice 

 obtuso mucronato ; racemis breviusculis ; floribus demum deflexis ; den- 

 tibus calycis sericei filiformi-subulatis laxis tubo gequilongis corolla (fla- 

 vida) paullo brevioribus. — California, Douglas ; in flower only. — A 

 specimen with forming fruit, like that of the foregoing, collected by Dr. 

 Gibbons, is ambiguous between the two, being glabrate, but with the 

 calyx-teeth nearly of the present species, and with subulate rigid stii^ules. 



h. Corolla alba vel ochroleuco-purpurascens, e calyce longius exserta, 

 recta apice subincurva, alarum et carinarum unguibus lamina 

 suba3quilongis. Pedunculi folia superantes : racemi elongandi, 

 multi- et conferti-flori, floribus mox deflexis. Foliola multijuga, 

 conferta, apice saepius retusa, infima cauli approximata. 



65. A. Crotalari^. Phaca Grotalarice., Benth. PI. Hartw. p. 

 307 ? P. demifolia, Torr. Bot. Whippl. Exped. (Pacif. R. E. Surv. 

 4, p. 24, 80), non Smith. Glabratus vel subglaber ; caule valido ad- 

 scendente ; stipulis triangularibus discretis ; foliolis aut lineari- aut 

 obovato-oblongis petiolulatis (6-lG lin. longis) ; corolla alba; legu- 

 mine ovoideo 1 - l|-pollicari chartaceo (rigidiori et minus inflato quam 

 subsequentis). — California. Near Monterey, Coulter, if the plant here 

 described be really Mr. Bentham's species, as I am disposed to con- 

 clude, from a study of sketches and notes kindly furnished by him. 

 But the specimens here described are by no means canescently pubes- 

 cent, nor should I quite term their legumes " sub-coriaceous," although 

 the mature ones are considerably firmer in texture than those of the 

 related species, — chartaceous they may be called : moreover, the teeth 

 of the calyx are much shorter than the tube in Coulter's plant, little 

 shorter than the tube in our specimens ; yet the following species 

 shows a similar diversity in this respect. The flowers of Coulter's 

 plant, moreover, seem to be fewer, and the leaflets more cuneate- 

 obovate ; in all ours they are oblong. (It is certain that Coulter's 

 plant is not that figured by Dr. Torrey, our no. 57.) The matei-ials 

 before me are from the three following sources. Near San Francisco ?
