4 Leguminosce. 



A small tree, 20-30 ft., twigs smooth, purple, young parts 

 puberulous ; 1. simple (unifoliolate), articulated on the short 

 petiole, 2-3 in., oval, rounded at base, acuminate or slightly 

 caudate, glabrous, rather coriaceous, reticulate venation pro- 

 minent beneath ; fl. f in., articulated on short pubescent ped., 

 3-5 together, arranged in small axillary racemes less than 

 I in. long ; cal.-segm. linear-lanceolate, acute, rigid, pubescent; 

 pet. longer than cal., obtuse, finely and densely pubescent ; 

 fil. hairy at base ; ov. pubescent ; follicle 1-1 \ in., much falcate 

 when young, afterwards nearly straight, tapering at base into

 tube, often declinate, fil. frequently diadelphous (9 and 1) or 

 monadelphous, rarely distinct ; ov. superior, with i-many 

 ovules on ventral suture, style simple, often declinate with the 

 stam.; fruit a dry pod (legume), dehiscent along both 

 sutures, or breaking up into joints, or indehiscent, rarely

 cotyledons large, generally plane-convex. 



It is necessary to divide this vast Order into 3 Sub-orders, 

 as follows : — 



I. Fapilionaceae. Pet. unequal, papilionaceous, imbricate, the 

 upper one (standard) outside in bud, the two lateral (wings) and two
