an inch and a half long, 8 or 9 lines wide, green above, bcneath Teiny and silvcry, 

 with a very ' iine and close whitish pubescence. Ilaccmcs strict, not intcrrupted, 

 many-flowered ; the " purple " flowers smaller than in G. glabella, 5 to 6 lines long. 

 Pedicels a line long, shorter than the lanceolate deciduous bracts. Calyx-teeth tri- 

 angular-lanceolate, nearly twice the length of the tube. Fruit not seen.

X Cologania A14GUSTIF0LIA {Kunth, Mimos. p. 209. t 58): "volubilis; foliis li- 

 nearibus obtusis subconcoloribus utrinque strigulosis; calycibus hispido-pilosis " 

 (Kunth ex D C .) \ leguminc falcati-gladiato hirto. — Kew Mexico, near EI Pasol 

 coU. of 1851. — This appears to be Kunth's C. angustifolia ; but I have not the 

 w^ork in which it is described and figured to refer to. Our plant has a strong and 

 deep perennial root ; from which proceed slender, branching, striate-anglcd, hcrba- 

 ceous stems, cinereous-hirsute, as is the foliage, &c., with copious short strigulose 

 hairs. Petioles 6 to 9 lines long. Leafletsfrom one io nearly two inches in length, 

 about two lines wide, of rather firm texture, exactly linear, very obtuse at both 

 ends, mucronate. Flowers in pairs, or sometimes solitary in the axils, on pedunclcs 

 half an inch long, which are bibracteate at the base and minutcly bibractcolatc next 

 to the villose-hirsute calyx : bracts and bractlets subulate. Corolla apparently vi- 

 olet-purple. Vexillum biappendiculate at the base with narrow inflcxed margins. 

 Legume narrowly linear, an inch to an inch and a half long, compressed, sabre- 

 shaped, 7 - 9-seeded. Seeds oval, with a small hilum, not strophiolate.

 Linnaa, 12. p. 287. New Mexico, near El Pasol coll. of 1851 ; in flower only. 

 The specimens are more pubescent and cinereous, the leaflets thicker and more 



h 



veiny, the flowers rather smaller and the calyx more hairy than in No. 603 of Coul- 

 ter's Mexican coUection, which is named C. pulchella by Bentham, and they belong 

 perhaps to a difierent species, but they accord well with Kunth's character.

 Honda and San Felipe ; June. " Flowers red." — This is more cinereous than I. 

 Anil (to which I had referred it in Pl. Lindh. 2. p. 172), and the pods are longer 

 and somewhat flatter, not tetragonal, but rather compressed (as De Candolle charac- 

 terizes I. Anil); I see no other essential diff^erence.

Psoralea Floridana, ShutfJewortJi, Pl Rugel, No. 163, appears to be just the same as V. Lupinellus; 



the legume of which should not have been called " small" in the Flora of N. America.
