84 AMERIMNON. 
This group seems best referred, on general grounds, to Miscolohium; the single species of which 
it is composed bears a considerable general resemblance to various American species of this section. 
The peculiar arrangement of the stamens, which recalls what is met with in the genus Pterocarpus, 
shows, however, that the group serves as a link between the sections Dis:olobium, where the stamens 
are normally monadelphous, and Dalbergaria, where they are normally isodiadelphous. 
61. DALBERGIA POL Prain sp. nov. 
А small to medium tree, 15—80 feet high. Leaves 4—8 in. long; leaflets usually 
9, sometimes 7, occasionally 11—19, ovate-lanceolate, base cuneate or in the proximal 
sometimes rounded, apex gradually narrowed to the obtuse slightly mucronate tip, 
chartaceous, dark-green and glabrous except the puberulous midrib above, glaucescent 
and finely sparsely adpressed-puberulous beneath, the distal the largest, 1:5 in. long, "65 
in. wide, rarely 5:5 in. long, lin. wide, gradually diminishing to the proximal “б in. 
long "35 in. wide; rachis 3—4 in, long, and petiolules *12 in. long, finely puberulous; 
stipules ovate-lanceolate, pubescent, very caducous. were in rather dense thyrsoid 
axillary or infraaxillary panicles, 2:5 in. long, 2 in. wide; peduncle stout, glabrous; 
branches short, rusty-pubescent; slender pedicles “2 in. long, very sparingly pubescent; 
bracts small, ovate, deciduous; epicalycine bracteoles deciduous, sparingly pubescent, 
ovate-lanceolate ; calyz campanulate, tube externally glabrous below sparsely puberulous 
above, “2 in. long; teeth unequal, lowest lanceolate as Jong as tube and longer than 
the subequal acute lateral and the ovate subeonnate upper pairs; corolla distinctly 
lineate, standard wide-ovate, emarginate, the cuneate base passing into the short broad 
stout claw; wing-petals oblong, sagittate on upper side, long-clawed; keel-petals long- 
clawed united above, blades hastate on upper side below; sfamens 10, connate at the 
base in a very short sheath, split on upper side, the filaments rather irregularly separated 
downwards from one-third to nine-tenths of their length so as to become irregularly 
and incompletely 38—5-adelphous; ovary glabrous except the long pubescent stipe; 
style subulate-conical, stigma minute; ovules 3—4. Pod oblong, coriaceous, glabrous 
except the short but distinct stipe, cuneate less often rounded at base, acute ог 
acuminate at the apex, 2:5—3'5 in. long, 1 in. wide, strongly reticulated opposite 
the 1—2 seeds; seed subreniform-oblong, much compressed, :35 in. long, “95 in. 
wide, "07 in. thick; testa black, shining.

A very distinct species, the precise localisation of which is rather difficult; the leaves and pods 
recall certain American Jfiscolobia more than they do any of our Asiatic Daltergias; the calyx and 
corolla are however equally suitable for the sections Miscolobium and Dalhergaria and at first sight 
the fact that the staminal sheath is divided would suggest Daibergario, where the normal arrangement 
of stamens is an isodiadelphous one, as the most suitable place for this tree. Тһе careful examin- 
ation of many flowers shows, however, that по matter how deeply divided the stamens in 
D. polyatelpha may be, and no matter how many groups they are arranged in, the filaments are 
always monadelphous at the base, not quite divided into two bundles as in а normal Dalbergaria. 
This fact, combined with the likeness of the species to several undoubted Miscolobia from other 
regions, renders it advisable to treat JD. polyadelpha also as a AMiscolobium,
