196 LEGUMINOSJD. 



10"'-12"' long, yellow and purplish-variegated ; legume 4" long, 2"' diam. : seeds 2'" long. 

 — Hab. West Indies (Benth.) ; [Cuba ! and Panama ! to Brazil and Ecuador !, tropical 

 Africa! and Australia!, East Indies]. 



Several species of Vigna and Dolic/ios, not occurring in recent collections, are mentioned 

 by Macfadyen as cidtivated in Jamaica : viz. V. unguiculata, Walp. (Bolichos, Jacq. Vind. 

 t. i3, 23); Dolichos spharospermus, DC. (SI. t. 117); B. tuberosus, Lam. (Plum. Ed. 

 Burm. t. 220. Desc. Fl. 8. t. 554); and B. sesquipedalis, L. (Jacq. Vind. t. 67). — B.fili- 

 formis, Macf. (non L.), is unknown to me, but from its " monadelplious stamens'* is no 

 congener of either of these genera: by its "falcate legumes" and "ovate leaflets" it differs 

 from B.filiformis, L., which likewise is an unknown Jamaica plant, and has " linear leaflets, 

 the middle twice as long as the lateral ones :" both are to be compared with Teramnus. 



35. DOLICHOS, L. 



Calyx campanulate, shortly 4-5-fid. Standard roundish, auricled at the base, bicallous 

 in the middle. Stamens diadelphous. Style cartilaginous, usually compressed above, and 

 hairy : stigma terminal. Legume compressed : valves convex or flat : seeds separated by 

 thin, spurious dissepiments. — Leaflets 3, stipellate ; inflorescence axillary, fascicled-race- 

 mose. 



96*. D. Lablab, L. Stem twining ; leaflets rhomboid-ovate ; racemes pcduncled ; calyx 

 4-fid, the upper lobe broader ; keel beaked-falcate ; style compressed ; legume scimitar- 

 shaped, flat-convex, with an oblique, or recurved, straightish point : margins submuricate : 

 seeds subcompressed : rhaphe thickish, white, two-thirds as long as their diameter.— Mart. 

 Fl. Bras. 24. t. 51. /. 2.— Lablab vulgaris, Sav. 



a. Corolla violet | legume 2"-3" long, 10"'-12'" broad: seeds oval, black, 5"'-6 r " long. 



£. albiflorus, DC. Corolla white ; legume 2i" long, 8'" broad: seeds oval-roundish, 

 black, 4'" long. — SI. t. 113. — Lablab leucocarpus, Sav. 



y. nankinicus,Sa.v. Corolla white ; legume 2"-3" long, 8"'-10"' broad: seeds oval, less 

 compressed, white, 5'" long. — L. perennans, BC. 



S. purpureus, Jacq. Corolla purple ; legume 3" long, 6"'-8'" broad : seeds oval-roundish, 

 purple, 4'" long.

 7); [all tropical countries]. 



36. PHASEOLUS, L. 



Calyx campanulate, 4-5-fid or 4-5-toothed. Standard roundish : keel spirally twisted ! 

 Stamens diadelphous. Style cartilaginous above : stigma oblique or lateral. Legume com- 

 pressed or subcylindrical. — Leaflets 3 (-1), stipellate, lateral usually oblique : inflorescence 

 axillary, fascicled-racemose. 



97. Ph. lunatus, L. Stem usually twining; leaflets ovate, pointed; peduncles shorter 

 than or as long as the leaves ; calyx 4-toothed, much longer than the bracteoles -. inferior 

 teeth 3-angular, superior truncate; legume scimitar-shaped, compressed, arcuate-beaked, 

 3-4-seeded : seeds subquadrate-roundish. — Besc. Fl. 8. t. 558. Ph. bipunctatus, Jacq. ; 

 inamoenus, L.; saceharatus, Macf.!; latisiliquus, Macf !; foecundus, Macf; limeusis, Macf. ? 

 — Flowers usually greenish-white ; legume 1"-\\" long, 8"'-5"' broad : seeds purple or 

 white. — Hab. Spontaneous, and cultivated in Jamaica!, Macf.; Al.; Antigua!, Wullschl.; 

 [Cuba! and Mexico! to equatorial Brazil!, tropical Africa ! and Asia !]. 



98*. Ph. vulgaris, L. Stem usually twining, leaflets ovate, pointed; peduncles 

 shorter than the leaves ; calyx 4-toothed, as long as the bracteoles : inferior teeth 3-angular, 

 superior subtruncate ; legume oblong-linear, subcompressed, subtorulose, straightish, few- or 

 many-seeded: seeds ovoid-oblong. — SI. t. 115. f. 2, 3. — Ph. nanus, L.; gonospermus, Sav.; 

 compressus, BC; dumosus, Macf. ? — Flowers usually white ; seeds variable in colour. — 

 Hab. Naturalized, and cultivated in Jamaica (SI., Macf); [tropical Asia ! and Africa]. 



99. Ph. adenanthus, Mey.l (1818). Stem usually twining: leaflets ovate, pointed; 

 peduncles few-flowered, usually exceeded by the leaves ; calyx 4-fid : inferior lobe lanceolate- 

 linear,- as long as the tube, lateral shorter, falcate, superior truncate ; corolla large, 3-4 

 times exceeding the calyx; legume linear, compressed, straightish or curved. — Wight. Ic. t. 

 34. — Ph. truxillensis and cirrhosus, Kth. (1823). Ph. rostratus, Wall. Ph. amcenus, Macf!
