Description
|
Tree to several m., the branchlets densely ferruginous-tomentulose. Leaves large, with a variable number of leaflets (5-10 pairs, fide N. Am. Fl.), 6-9 pairs in Panamanian specimens seen; petiole less than 2 cm. long, essentially terete, tomentulose like the branchlets; rachis up to 2 dm. long, similar to the petiole, not winged, bearing a sessile, cupuliform gland 1-2 mm. in diameter between insertion of the petiolules; leaflets few to several pairs, oblong or elliptic to occasionally ovate-lanceolate, mostly about 10 cm. long and 3-4 cm. broad in the terminal leaflets, 1,2 or less this size in the lowermost leaflets, acute or short-acuminate apically, rounded or obtuse and somewhat inequilateral basally, lightly strigose- puberulent or subglabrate above, rather densely pubescent and paler below; stipules apparently ovate, about 2 mm. long, caducous. Inflorescence of pedunculate spikes up to 6 cm. long, solitary, geminate or fasciculate from the axils of the leaves, the floriferous portion scarcely 2 cm. long; bracts ovate, very small, ferruginous- tomentose like the axis. Flowers congested, spicate on the axis, whitish; calyx tubular, up to 12 mm. long (reported as short as 5 mm. in Guatemalan and Costa Rican specimens), usually cleft on one side for as much as 1/3 its length, puberulent or tomentulose without, the teeth minute; corolla elongate, tubular, 20-25 mm. long, appressed-villous without, the lobes about 2 mm. long; stamens many, almost 4 cm. long, united below into a tube about equalling the corolla; style somewhat exceeding the stamens, the stigma expanded. Legume variously reported glabrous or tomentulose?, flat or subterete?, up to 25 cm. long and 1 cm. wide?, the valves expanded and costate at the edges.

Note
|
The usual concept of this species seems to include a remarkably variable group of specimens. Certainly various authors have been at great divergence in writing descriptions of it, and specimens seen show great differences in leaflet number, calyx size, etc. Dimensions given by Pittier (Contr. U. S. Nat. Herb. 18:187) for the Fendler 5i specimen at the Gray Herbarium in no way approximate those for Fendler 5i at the Missouri Botanical Garden. Yet in spite of such lack of constancy the species seems to form an unit distinguishable from most other Ingas within its range (especially by the large, elongate corolla, the several pairs of leaf- lets, the wingless rachis, and the spicate inflorescence).
