66 FLORA OF JAMAICA Phaseohis 



Benth.). Stem erect, a foot or more bigh, shrubby at base, with whitish 

 deflexed hairs. Leaflets 3-7 cm. 1. Racemes 7-12 cm. 1. ; peduncles 

 1 • 5-3 dm. 1. ; pedicels very short, geminate. Bracts and bracteoles bristle- 

 like, deciduous; bracts 6 mm. 1., bracteoles 3 mm. 1. Calyx 4-6 mm. 1. ; 

 teeth much shorter than the tube, upper triangular, lower lanceolate, 

 awned. Corolla blood-coloured; standard about 1-5 cm. 1., concave, 

 narrowed at the base, pale red ; wings about twice as long as the standard, 

 deep crimson; keel whitish.. Pod spreading, many-seeded, 8-10 cm. 1. 

 Seeds ellipsoidal, brown. 



The Linnean species P. lathyroides is based on the Jamaican specimens 

 of Sloane & Browne, which have narrow leaves ; this form is distinguished 

 by Bentham as P. semierecttis v. angustifolia. The typical P. semierectus 

 (Plukenet in Herb. Sloane xcvii. 84 in Herb. Mus. Brit.) has ovate-elliptical 

 leaves. Both forms occur in Jamaica. Plukenet's specimen has the leaves 

 and pods of this species, and also the pods of apparently P. Mungo L., and 

 these pods of another species have been drawn in Plukenet's figure as 

 attached to the leafy twig.
