Description
|
Shrub, mostly scrambling or scandent to 3.5 m tall; twigs scurfy to cobwebby- pubescent with mostly sessile, slender-radiate stellate hairs, white. Leaves ovate or elliptic, sometimes broadly so, to 18 cm long, short-acuminate apically, basally obtuse or rounded, sometimes slightly oblique or dimidiate, glabrescent on the lamina, the veins puberulent above, ca. 5 on each side of the midvein; petioles 2-3 cm long; minor leaves mostly wanting. Inflorescence a several-flowered fascicle on a short, peduncle-like base at a node of the stem; pedicels filiform, 10 mm long, glabrate, becoming stouter and 15 mm long in fruit. Flowers with the calyx ca. 2 mm deep with a few scattered, persistent stellae, the teeth slender, 3 mm long; corolla 13 mm long, glabrous near -the. base, pubescent on the upper portion with sessile stellae; stamens unequal, 4 filaments ca. 1 mm long, the fifth 4 mm long, the anthers 4 mm long, the longer stamen with a slightly larger anther, slender and elongate; ovary ellipsoid, glabrous, 2.5 mm long. Fruit ?globose, red, 15-20 mm across, the calyx somewhat accrescent, the cup be- coming woody and the teeth ultimately at least partially reflexed and stouter but not much longer.

Note
|
The slender radii of the whitish cobwebby stellae and the long, filiform calyx teeth on the flower buds distinguish this species from other Panamanian taxa. It is closely related to L. multiflora Bitt. of Costa Rica, but that species has short calyx teeth in bud. The calyces of mature fruits tend to resemble those of L. guianense of Panama and South America, but there are usually a few hairs remaining at the base of the calyx; L. guianense usually has none. This species is most common in the lowlands of Bocas del Toro and in Cocle at middle elevations. Lycianthes hawkesiana is dedicated to Professor J. G. Hawkes of Birmingham, a long-time student of the Solanaceae.
