LEGUMINOS.E 423 



No. 1. Rotund, obtuse, entire or shallowly emarginate (appa- 

 rently deformed in specimen sketched). 



No. 2. Pinnately trifoliolate ; lateral leaflets opposite, elliptic, 

 small, shortly petiolulate ; terminal leaflet similar but much larger 

 and with a longer petiolule. 



Nos. 3-5. Pinnately trifoliolate, very similar to the 2nd. 

 Branches in the axils of the first and second leaves similar to those 

 of the primary stem. 



Carmichaelia pilosa, Col. 



Hypocotyl erect, terete, slender, about 7 mm. long. 



Cotyledons opposite or subalternate (perhaps accidental), oblong- 

 spathulate, obtuse, entire, narrowed to the base. 



Stem shrubby, slender, spreading, or diffuse and branching at 

 the base, striate, terete at the base, and becoming dilated and 

 flattened upward, deep brown and covered with an ascending, ad- 

 pressed, white pubescence. 



Leaves cauline, simple and ternately compound, alternate, stipu- 

 late, distichous, petiolate and petiolulate, pubescent on both surfaces 

 as well as the petioles, becoming glabrous on the upper surface 

 when old ; pubescence adpressed upwards ; petiole subterete, chan- 

 nelled above, about 5-8 mm. long, articulated at the base and apex 

 below the leaf or leaflets ; stipules small, scarious, and greyish, 

 triangular or rounded and toothed, adpressed to the stem and 

 petiole. 



No. 1 to some indefinite number. Simple, obcordate, entire, 

 articulate with the petiole, indistinctly penninerved. 



Ultimately some leaves show a terminal with one lateral leaf- 

 let. Occasionally a few leaves have three leaflets ; lateral ones 

 similar but much smaller than the terminal one ; petiolule of terminal 

 leaflet about 2 mm. long ; lateral ones much shorter. As the branch 

 weakens towards the tip, the leaves are again reduced to a single 

 leaflet. 



Sesbania aegyptiaca, Pers, (fig. 276). 



Fruit a legume, linear, terete or tetragonous, transversely 

 septate between the seeds, dehiscing by two valves or not at all. 



Seed transversely oblong, terete, obtuse at each end, smooth, 

 shining, pale yellow ; testa thin ; hilum conspicuous above the 

 middle on the ventral aspect, thickened, brown ; chalaza ventral, 

 towards the opposite end, but not quite basal. 



Endosperm in the mature seed rather copious, cartilaginous,
