Leaves opposite to alternate, subsessile, lanceolate, ovate or deltoid, apically acute, basally cuneate or truncate, the margins crenate to dentate, the teeth often salient, mostly 2-4 cm long, 8-16 cm wide, the midvein prominent on both sides and a pair of flanking longitudinal veins conspicuous beneath, the minor pinnate venation evident beneath, obscure above, scabrous above, scabridulous beneath with short, acicular hairs on multicellular bases, shiny above; petioles flat, broadly cuneate, 1-2 mm long. Inflorescences solitary flowers in the upper leaf axils, sometimes aggregated to appear racemose, the pedicels stout, glabrate, ca. 2 mm long, a linear to narrowly obovate hirsute bract arising from just below the apex. Flowers with the calyx broadly campanulate, hirsute, ca. 8 mm long, lobed about 1/3 way down, the lobes somewhat unequal, deltoid with subulate tips; corolla yellow, only slightly exserted, 1.0-1.3 cm long; stamens 4, didynamous, the anther theca forming an inverted U, 1.5 mm long over the filament apex; style circinnate in bud, 2-lobed.

Note
|
Although a number of collections were available from Central America, none had well preserved flowers, hence the omission of floral details above. All Panamanian collections of Alectra aspera are from the Canal Zone and most are from the Pipeline Road just north of Gamboa, an area of slight dis- turbance in premontane wet forest. It grows in the open.

|
Distribution
|
ranges from Brazil to Guatemala and it occurs in the Antilles.
