obovate-cuneate or roundish exceeding- the bracteoles, lateral and 

 anterior petals obsolete, or one of the lateral ones occasionally deve- 

 loped shorter than or nearly equalling* the posterior. Stamens 10, all 

 antheriferous, filaments filiform, glabrous, free or minutely coherent 

 at base ; anthers small, broadly elliptical, versatile, dehiscing longi- 

 tudinally. Ovary densely hairy, shortly stipitate, biovulate ; style 

 filiform, stigma terminal, capitate. Legume not seen. — Tree, unarmed, 

 glabrous excepting the inflorescence. Leaflets unijugate, coriaceous, 

 2-3-nerved. Flowers in short, dense, axillary racemes. Bracts sca- 

 rious, deciduous ; bracteoles enclosing the bud, spreading or reflexed 

 during flowering. 



Based upon the following species which I met with sorted away in Cynometra, with 

 which genus it agrees remarkably in habit. It is highly probable that future disco- 

 veries will materially modify our treatment of the few species of i 'cesalpiaiece, distributed 

 in almost as many genera as species, in which the calyx is either obsolete or reduced to 

 minute squamae, and the buds enclosed between valvate bracteoles. 



1. A. cynometroides, Oliver in Rook. Ic. PL 1. 1066. A tree of 50 ft. 

 (Mann), wholly glabrous excepting the inflorescence. Leaflets uni- 

 jugate, coriaceous, shining, obliquely subsemi-elliptical or obovate- 

 oblong, shortly and rather acutely acuminate, distinctly 2-nerved with 

 a third outer faint nervure soon evanescent, sessile ; 2J-3-J in. long, 

 1-1 f in. broad ; petiole stout, -J in. or less. Racemes dense, rusty- 

 pilose, axillary and terminal, solitary or fascicled, not exceeding 1-1 A- 

 in. in our specimens. Bracts broadly rotundate-ovate obtuse or broadly 

 pointed, firm, or scarious in texture, longitudinally oo -nerved, about 

 2 lines long. Pedicels 1-2 lines. Bracteoles persistent during flower- 

 ing, inserted immediately under the flower, broadly ovate-elliptical, 

 mucronate, strigose-pilose outside, 2 lines long. Petal rotundate or 

 broadly ovate, subcuneate at base, slightly exceeding the bracteoles.

32. BURKEA, Hook. ; Benth. et Hook. f. Gen. Plant, i. 587. 



Flowers small, subregular. Calyx campanulate 5-fid, lobes 5, rounded. 

 Petals 5, subequal obovate or elliptical obtuse, imbricate in aestivation. 

 Stamens 10, antheriferous; filaments rather short; anthers oblon«- 

 with a minute, apiculate connective, versatile, 2-celled, dehiscing lon- 

 gitudinally. Ovary subsessile, hirsute, 1-2-ovulate ; style very short, 

 thick, stigma obliquely truncate or concave. Legume oblong or ellip- 

 tical, obtuse, flat, thinly coriaceous. Seed compressed, albuminous ; 

 cotyledons thin, flat; radicle short, thick, included in basal notch. — 

 Small unarmed tree or shrub, with stout extremities. Leaves abruptly 

 bipinnate, pinnae 1-3-6-jugate opposite or subopposite, leaflets usually 

 6-12 to each pinna, alternate, petiolulate or subsessile, ovate to oblong, 

 obtuse. Stipules minute or obsolete. Flowers small, in slender, simple, 

 or sparingly branched axillary spikes, collected with the tufted leaves 

 at the ends of the branches.
