52 FLOKA OF JAMAICA Mucuna 



4 segments or 4-5 teeth. Standard auricled at the base, shorter 

 than the wings. Uppermost stamen free, the rest united ; 

 anthers alternately basifixed and versatile, the latter bearded 

 and with filaments somewhat thickened above. Pod thick, 

 leathery, hairy, often with stinging hairs ; the seeds separated 

 by partitions or by tissue; hilum enlarged. 

 Species 30, growing in the tropics.

 DC.) ; leaflets elliptical, abruptly and shortly acuminate, glabrous 

 on both sides ; peduncle about 10 times as long as the petiole, 

 with several flowers, 1, 2 or 3 together in a contracted raceme at

Bare ; in fl. Sept. and Oct. ; Browne ; St. Mary, McNab \ mountain 

 woods, Manchioneal, Wilson. West Indies, Panama, Brazil. 



Stem climbing high over trees, glabrous. Leaflets 8-16 cm. L, 

 5-7*5 cm. br. ; petioles 5-13 cm. 1. Peduncle to 1;5 m. 1., slender, 

 pendulous. Flowers blue-purplish with a yellowish keel. Calyx, tube 

 1-1 - 2 cm. L, truncate, toothed, uppermost tooth emarginate, lateral 

 nearer to the lowest which is the longest, about 4 mm. 1. Corolla : standard 

 3-4 cm. L, adpressed to wings and keel, three-fourths to nearly as long as 

 the wings, very broad ; wings with a long claw which is 1-1 '5 cm. 1. and 

 tomentose at the edges ; keel slightly longer than the wings. Pod 12-23 

 cm. l v 5 cm. br., hispid with bristly stinging hairs and also pubescent. 

 Seeds about 4, flattened-rounded, almost surrounded by the hilum, 3 cm. 

 in diam., or even larger. 



Dolichos urens L. Syst. is based on Browne's description of Zoophthal- 

 mum and on Plukenet's figure. Plukenet's specimen in Herb. Sloane has 

 leaves which are glabrous on both sides, and Browne's description states 

 that the peduncle is " seldom under four or five feet in length " ; it is 

 therefore clear from these two diagnostic details to which species Linnseus's 

 name, as given in the Systema, belongs. Jacquin in Sel. Stirp. Amer. 202, 3, 

 has given long and careful descriptions of this and a second West Indian 

 species, which he calls respectively D. altissimus and D. urens, thus 

 applying Linnseus's name to the wrong species. De Candolle followed
