Aphanocalyz. | XLVII. § CHSALPINIEH (OLIVER). 319 
obovate-cuneate or roundish exceeding the bracteoles, lateral and 
anterior petals obsolete, or one of the Yateral 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 futnre disco- 
veries will materially modify our treatment of the few species of Cesalpiniee, distributed 
in almost as many genera as species, in which the calyx is either obsolete or reduced to 
minute squame, and the buds enclosed between valvate bracteoles. 
1. A. cynometroides, Oliver in Hook. Ic. Pl. t. 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 ; 24-3} in. long, 
1-lfin. broad; petiole stout, Jin. or less. Racemes dense, rusty- 
pilose, axillary and terminal, solitary or fascicled, not exceeding 1-1} 
in. in our specimens. Bracts broadly rotundate-ovate obtuse or broadly 
pointed, firm, or scarious in texture, longitudinally o -nerved, about 
2lines long. Pedicels 1-2 lines. Bracteoles persistent during flower- 
ing, inserted immediately under the flower, broadly ovate-elliptical, 
mucronate, strigose-pilose outside, 2lines long. Petal rotundate or 
broadly ovate, subcuneate at base, slightly exceeding the bracteoles. 
Upper Guinea. Mount John, Kongui river, Mann! 
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 estivation. 
Stamens 10, antheriferous; filaments rather short; anthers oblong, 
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, pinne 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 iy of the branches.
