Description.

Shrubs or small trees to 6 m tall, stems tetragonal but soon terete and densely pubescent with sessile and stipitate stellate hairs; the nodal line present yet slight. Leaves of a pair equal to subequal in length. Petiole 0.8-2.5 cm long. Leaf blade 6-18 × 2-6 cm, 3-5 nerved, narrowly ovate to elliptic or ovate, acute to rounded at the base, acute to acuminate or rarely obtuse at the apex, the margins entire or obscurely denticulate, adaxially glabrous, abaxially densely covered with stellate and stipitate trichomes. Inflorescence a terminal panicle 6-12 cm long branched above the base but sometimes appearing branched at the base because of multiple inflorescences arising at opposing meristems at the terminal node, accessory branches apparently absent; bracts and bracteoles to 3 mm long, linear, early deciduous. Pedicels 2-7 mm long, covered with stellate and branching trichomes. Flowers (4-)5(-6) merous, calyptrate. Floral buds 8-9 × 3-4 mm, pyriform to lachrimiform, truncate or rounded at the base, narrowly acute and acuminate at the apex, the apex with somewhat discernible lobes, the calyptra well differentiated from the hypanthium; hypanthium 4-5 × 3.5-4 mm, campanunlate, sparsely to densely beset with stellate hairs and minute brown glands. Petals ca. 5 mm long, white, obtriangular, spreading to a little reflexed, rounded apically, glabrous. Stamens 9-14, 3-3.5 mm long, radially arranged around the style but apparently becoming zygomorphic becasuse of the style bending to one side below the stigma, the filament ca. 1.5 mm long, white, lacking a geniculation, anthers 1.5-2 mm, linear and slightly recurved, yellow, the pore ca. 0.1 mm, terminal. Ovary 5-7 locular, inferior, apically glabrous and forming a low collar around the style base. Style 2-3 mm long, bent below the stigma, vertical and horizontal distance from the stigma to the anther absent; stigma truncate, ca. 1 mm wide. Berry 5 × 5 mm, blue black. Seeds 0.4-0.5 mm, ovoid, smooth.

Distribution

(Fig. 85View Figure 85). Cuba and the Dominican Republic, 750-1300 m elevation.

Note that in Dominican Republic a pubescent morphotype of Conostegia superba  has been collected in the same place. They are similar but when looking at the flower buds, Conostegia lindenii  has pubescent buds with the lobes somewhat evident in the calyptra apex. In Conostegia superba  on the other hand, the flower bud and calyptra are glabrous and the lobes not discernible at all.
