LEGUMINOS^E 395 



Pachyrhizus angulatus, Rhynchosia viscosa, Flemingia Gra- 

 hamiana, &c. The first pair of leaves in the last species are 

 small and rotund, while those of Rtrynchosia viscosa are cor- 

 date. The lamina of the first pair in Pachyrhizus angulatus 

 is broadly triangular. Immediately above these the stem 

 becomes slender and twining, as also in Vigna vexillata. The 

 first pair of leaves and the leaflets of the succeeding ones in 

 the latter are comparatively small and lanceolate. The first 

 pair in V. lutea are ovate-subcordate. Lateral shoots from the 

 axils of the cotyledons in Phaseolus multiflorus are produced 

 if the primary axis gets destroyed, and the first leaf on them 

 is simple and subrotund. The first four leaves of Erythrina 

 Vespertilio are transversely rhomboid ; the fifth has small 

 rhomboid leaflets. Many of the above species have small 

 subulate stipules and stipellae. A very curious case occurs 

 in a plant questionably named Erythrina suberosa (fig. 287). 

 The cotyledons are subterranean, and the first pair of leaves 

 opposite ; but four at least of the primary ones are simple, 

 trifid, or trilobed, subpalmate and palmately five-nerved. 



The most striking exception observed in the tribe occurs 

 in Kennedya Marryattas. The cotyledons are linear-oblong, 

 fleshy, sessile, furrowed beneath, and 2-6-3 cm. long. The 

 first pair of leaves are suborbicular, simple, and often un- 

 equal in size. 



Tribe Dalbergiece. Few of the species of this tribe have 

 come under my notice, and those show modifications of the 

 leading type. Dalbergia hupeana has obliquely ovate cotyle- 

 dons cut away at the base on one side. The first two leaves 

 are opposite with five obovate leaflets. The cotyledons of 

 Lonchocarpus latifolius (fig. 292) are fleshy, but aerial and 

 falcate by an indentation on one side. The first two leaves 

 are opposite, ovate, and simple, reminding one of what occurs 

 in the Phaseolese. The third leaf is alternate. The sixth to 

 the eleventh inclusive have eleven leaflets. 



Tribe Sophorete. All the species observed in this tribe 

 have subterranean, fleshy cotyledons, varying considerably 

 with the seed in shape, size, and thickness. Sophora 

 secundiflora (fig. 293) has obovate somewhat oblique cotyle- 

 dons, and the first seven leaves at least are alternate, simple,
