Rediscovery of Ossaea alloeotricha, an endemic of the high-elevation Massif de la Hotte, Haiti, and its transfer to Miconia (Melastomataceae: Miconieae). Brittonia 56: 159–165. 2004.—Ossaea alloeotricha, described by Urban on the basis of material with very immature flowers, has been re-collected (in flower and fruit) in the cloud forests and moist forests dominated by Pinus occidentalis in the vicinity of Pic le Ciel, 2150 m, on Morne Formon of the Massif de la Hotte (western group), Haiti. The mature flowers of this species have broadly elliptic to suborbicular petals with rounded, asymmetrically notched apices, clearly indicating a placement in Miconia, not Ossaea or Leandra (which have acute to acuminate petals); the species is here transferred to Miconia (sect. Cremanium). Miconia alloeotricha is provided with an expanded description and compared with M. desportesii, M. monciona, M. sphagnicola, and M. tetrandra, the other species of Miconia sect. Cremanium occurring in Hispaniola (Dominican Republic and Haiti), and with the phenetically similar M. acuminata (sect. Chaenopleura), with which it occurs in the moist forests near and at the peak of Morne Formon. With the transfer of Ossaea alloeotricha to Miconia, we estimate that 58 species of Miconia occur on Hispaniola.
