Description
Species Description - Macrophyllidious trees 5-12 m with trunk 1.5-2.5 cm dbh and lenticellate branchlets, appearing glabrous but the young branchlets and all lf- and inflorescence-axes thinly puberulent with incurved pallid hairs to 0.1-0.3 mm, the olivaceous lvs moderately bicolored, the lfts dull on both faces, a little paler beneath, commonly glabrous facially and minutely ciliolate but rarely (in Minas Gerais) rather densely puberulent dorsally overall, the inflorescence a series of short efoliate simple pseudoracemes or narrow panicles of few-fld umbelliform capitula, the lower pseudoracemes arising from the axil of coeval lvs and shorter than them, the upper ones forming a shortly exserted efoliate panicle; perulate buds axillary to many mature lf-stks, ovoid, 1-5 mm, the castaneous scales imbricate, dry, striately nerved, glabrous dorsally, sometimes minutely ciliolate. Bud-scales ovate to broadly triangular 0.3-2.5 mm long, proximal ones shorter than distal ones, striate, green or brown, thrown off as the new shoot begins to elongate, each leaving a linear transverse scar at base of branch. Stipules 0. Lf-formula (ii—)iii(—iv)/(8—)9—15; lf-stks 4-10.5 cm, the petiole 2.5-5.5 cm, the longer interpinnal segment 1.1-2.4 cm, the ventral groove continuous between pinna-pairs; petiolar nectary near or above midpetiole, sessile, cupular or shallow-cupular 1-1.6 mm diam, in profile 0.3-0.6 mm tall, often imperfect or eaten and in random lvs apparently immersed or even obsolete, minute nectaries at tip of some pinna-rachises, none between pinna-pairs; first pair of pinnae somewhat shorter than further ones, the rachis of these 5.5-10 cm, its longer interfoliolar segments (5—)6—10 mm; pulvinules in dorsal view 0.6-1.1 x 0.4-0.6 mm; lfts proximally decrescent, the anterior one of the first pair often greatly reduced or absent, the rest subequilong, the blades narrow-oblong from inequilaterally cuneate or wide-flabellate base, sharply deltate-apiculate, the larger ones 12-20 x 4—6 mm, 2.7-3.5 times as long as wide; venation of 4—5 primary nerves from pulvinule, the dorsally prominulous pallid midrib a trifle forwardly displaced, either straight or gently incurved, the inner posterior nerve expiring below midblade, the outer posterior and one anterior primary nerves very short, the midrib giving rise on each side to 5—8 ascending, very slender secondary nerves mostly expiring or only obscurely camptodrome within the plane margin, the whole venation of upper face immersed or finely engraved, prominulous only beneath. Primary axis of each pseudoracemose or paniculate element of the inflorescence 2-6 cm, the secondary axes, when present, not over 1.5 cm, some of them arising from same node as pedicels; peduncles 3-6 per node of inflorescence, the longest 8-13 mm, the capitula umbelliform 5-11-fld, the fls dimorphic, the peripheral ones slenderly pedicellate, the terminal one sessile on a short pedestal, the receptacular axis 1—2(—2.5) mm; PERIPHERAL FLS; pedicel 1.5-6 x 0.2-0.5 mm; perianth 5-merous; calyx turbinate-campanulate or somewhat urn-shaped 2-3 mm, externally either glabrous or minutely puberulent, the depressed-deltate ciliolate teeth 0.1-0.25 mm; corolla 4-5 mm, silky-strigulose externally, the ovate lobes 1.4-2.2 x 1-1.2 mm; androecium 26-38-merous 11-16 mm, the stemonozone 0.3-0.45 mm, the tube 1.5-2.2 mm, included in corolla; ovary glabrous, symmetrically conical at apex; style about as long as the white filaments, the stigma poriform; TERMINAL FL: calyx 2.2-3 x 2 mm; corolla 4.5-6 mm; androecium 30-46- merous, the tube 3.5-6.5 mm, the free portion of some filaments dilated at base. Pods solitary pendulous, the piano-compressed body in profile broad-linear straight 12-22 x 2.7-4.3 cm, abruptly contracted at base into a stipe 4-8 mm, rounded and mucronate at apex, when well fertilized 8-10-seeded, framed by almost straight, 2-ribbed and centrally sulcate sutures ±1.3 mm wide, the papery, brown or livid-brown valves glabrous but often minutely granular along the sutures, externally finely and sharply transverse-venulose, whitish and smooth within, quite free from each other between seeds; dehiscence through both sutures, inert; funicles filiform, sigmoidally contorted at apex; seeds transverse at middle of pod, disciform 10.5-12 x 8-10 x 0.8-2 mm, a trifle longer than wide, the pallid grapeskin testa translucent, produced around the seed’s periphery as a wing near 1 mm wide, pleurogram 0; the pale green cotyledons concealing the radicle; endosperm 0.
Distribution and Ecology - In semideciduous forest, mata de cipó, and cerrado, sometimes on granitic outcrops, between 400 and 1000 m, not uncommon along the crest and valleys of Chapada Diamantina between 10° and 14°S in Bahia, Brazil, extending W to Sa. do Açuruá and E down the Paraguaçú to Cruz de Almas; somewhat isolated in middle valley of Río Jequitinhonha in NE Minas Gerais at latitude 16-17°S. — Map 37. — Fl. X-XII; fr. II-VIII.
