LEGUMINOS.E 475 



Leaves. No. 1. Pinnate ; leaflets linear-oblong, obtuse, entire, 

 sessile or subsessile. 



No. 2. Bipinnate ; leaflets linear, obtuse, entire. 



Acacia acanthocarpa, Willcl. 



Hypocotyl 2-5 mm. long, light green or colourless. 



Cotyledons thick, fleshy, broadly oblong, entire, slightly cordate 

 at the base, obtuse, shortly petiolate, glabrous, trinerved. 



Stem erect, terete, herbaceous at first, ultimately woody ; 1st 

 internode 2-3 mm. long, finely pubescent. 



First leaves compound, abruptly pinnate, petiolate, stipulate, 

 alternate, cauline ; leaflets opposite, shortly petiolulate, entire, oval- 

 oblong, obtuse, eight in first leaf; the petiole and petiolules are 

 slightly hairy. 



NOTE. The cotyledons are often three in number ; out of eleven 

 plants four had three cotyledons. 



TEIBE 



Pithecolobium Saman, Benth. 



Hypocotyl woody, erect, terete, glabrous, 6'5 cm. long, 2 mm. 

 thick, pale green. 



Cotyledons (dropped). 



Stem becoming woody, erect, terete, striate, densely hairy and 

 almost woolly on the younger parts, pale green ; 1st internode 

 2'5 mm. long ; 2nd 9 mm. ; 3rd 1-1 cm. 



Leaves cauline, compound, alternate (first two opposite), petio- 

 late, stipulate and stipellate, ciliate, pubescent beneath and on 

 the petioles, ultimately becoming glabrous except the petioles and 

 apparently the margin. 



No. 1. Simply and abruptly pinnate, with three pairs of opposite 

 leaflets ; lowest pair lanceolate, acute, slightly unequal at the 

 base ; second pair oblong, obtuse, cuspidate ; third pair obovate, ob- 

 long, obtuse, cuspidate, all petiolulate ; stipules free, subulate, acute. 



The primary rachis of the first leaf frequently ends in a 

 small, lanceolate, acute leaflet, thus making the leaf imparipinnate. 



No. 2. Bipinnate, consisting of one pair of pinnas or primary 

 divisions, and terminating abruptly ; pinnfe of two pairs of leaflets 

 with sometimes an odd one at the base laterally, terminating in a 

 subulate acute mucro, stipellate at the base ; leaflets unequal in 

 size, oval, oblique, obtuse, or subcuspidate, unequal at the base ; 

 one of the basal ones is frequently very small, namely the one on 

 the basal, anterior side of the pinna.
