404 PHANEROGAM I A. 



4. Indigofera Obrajillensis, Sp. Nov. 



I. herbacea, cinereo-strigosa ; caule decurnhente ; foliis pinnatis; foliolis 

 Q-S-jugis obovatis oblongisve mucronatis utrinque canescenti-strigosis 

 supra suhglabratis ; racemis breviier pedunculatis folio brevioribus; 

 mucrone antherarum nudo; legumine deflexo lineari recto canescenti- 

 puberulo. 



Hab. Obrajillo, Peru ; abundant. (Also gathered by Mr. M'Lean.) 



Apparently an herbaceous perennial, cinereous throughout with the 

 close strigose pubescence of the related species. Stems decumbent or 

 spreading, a foot or more in length. Stipules subulate-awned, 5 lines 

 long, or the lower broader and shorter, brownish, strigose-pubescent 

 externally, rather persistent. Leaves pinnate, very short-petioled. 

 Leaflets 6 to 8 pairs, obovate or oblong, from 4 to 8 lines in length and 

 about 3 lines wide, mucronate, some of them rather conspicuously so, 

 canescently strigose both sides, at least when young, the upper surface 

 becoming more or less glabrate with age, veinless, slightly petiolulate. 

 Peduncles (half an inch to an inch or rather more in length), with the 

 short and dense spike or raceme, shorter than the leaf. Pedicels less 

 than half a line long. Bracts subulate, as long as the calyx. Calyx 

 strigose-hirsute ; the lobes subulate-acuminate, longer than the tube. 

 " Corolla scarlet, showy :" vexillum 4 or 5 lines long, a little hairy 

 outside. Anthers uniform, strongly mucronate ; the mucro naked (not 

 bearing a tuft of short bristles). Legume deflexed, linear, an inch and 

 a half long, straight, canescently puberulent, pointed, turgid, several- 

 seeded. 



Our specimens are in flower only: the fruit is described from a 

 plant in the Hookerian herbarium, gathered by Mr. M'Lean. The 

 species is manifestly allied to I. tephrosioides, H. B. K. ; but the leaflets 

 are broader, strigose-canescent both sides, and destitute of the fine 

 parallel veins which are delineated in Kunth's figure of that species, 

 nor have they a long and awn-like mucronation ; the peduncles are 

 shorter; and there is no trace of a tuft of bristles surmounting the 

 cusp of the anthers. It needs, however, to be more critically com- 

 pared with that species.
