Flora of Barro Colorado Island

Conostegia speciosa

Naud., Ann. Sci. Nat. Bot., sér. 3,16:109.1851

Shrub, seldom more than 2 m tall, very densely pubescent on all external surfaces, the trichomes of stems and in­florescences stalked-stellate. Petioles 1-4 cm long; blades ± ovate, acuminate, obtuse to rounded at base, 10-27 cm long, 5.5-13 cm wide, rugulose and mostly simple­-pubescent above, with both stalked-stellate and simple trichomes below, minutely serrate, pliveined, the veins 5-7, raised below. Panicles congested, ± maroon, ter­minal; flowers ca 1.5 cm diam, opening few at a time, often on same inflorescence with fruits, the buds violet, ovoid; petals 6 or 7, white to pink, ± rounded; stamens 12 or 14, directed to one side, geniculate below anther; anthers all with apices clustered around stigma; style short and thick, strongly bent to one side near apex; stigma green. Berries densely pubescent, dark purple, ca 1.5 cm diam; seeds minute, numerous. Croat 6340.

Common in clearings; occasional along the margin of the lake. Flowers and fruits throughout the year. Foster 1134 and 1211, collected along the shore on Peña Blanca Point, represent an extreme variation of C. speciosa or possibly a distinct variety of it. It has been suggested by C. Schnell (pers. comm.) that they are hy­brids between C. speciosa Naud. and C. subcrustulata (Beurl.) Tr. In general appearance they look like C. specliosa, but they have only sessile stellate trichomes on the lower leaf surface as in           C. subcrustulata.

Costa Rica to northern South America; Jamaica. In Panama, known principally from tropical moist forest in the Canal Zone, Bocas del Toro, San Blas, Veraguas, Panama, and Darién, known also from tropical dry forest in Panama (Taboga Island), from premontane moist forest in the Canal Zone and Panama, from premontane wet forest in Coclé, and from tropical wet forest in Colon and Coclé.
