“…The diverse and highly endemic flora of the Sierra de Baoruco is also treated in Hager & Zanoni (1993) and García et al (2001). The description of Henriettea uniflora adds to the species of Melastomataceae that are known to be endemic (or nearly endemic) to the eastern peaks of the Sierra de Baoruco; others include Mecranium ovatum, which also occurs farther west, in the mountains south of Puerto Escondido (Skean, 1993), Miconia alainii (Judd & Skean, 1994b), M. howardiana (Judd et al, 1995), and Sagraea gracilis (Liogier, 1971). A striking tree of these forests, which is also endemic, is Magnolia hamori (Howard, 1948;Guerrero, 1993).…”

Henriettea uniflora, which is known only from a diverse moist montane forest in the vicinity of Loma Trocha de Pey (or "Monteada Nueva"), Loma Pie de Palo, and Loma Remigio, the easternmost peaks of the Sierra de Baoruco, is described and illustrated. It is compared to species of the Henriettea squamulosa complex, especially H. squamulosa and H. ciliata. The species of this complex are characterized by an indumentum of ferruginous, stellate-lepidote hairs.

“…subcompressa, especially some plants from the Sierra de Bahoruco occurring west of the Hoyo de Pelempito. It may seem surprising to find a distinct subspecies isolated in the "Monteada Nueva" region (= Loma Trocha de Pey), however several species of Melastomataceae are similarly restricted to this small geographical area, i.e., Henriettea uniflora Judd et al (2008: 219), Mecranium ovatum (except for a single collection in the mountains south of Puerto Escondido, see Skean 1993), Miconia alainii, M. howardiana, and Sagraea gracilis (Liogier 1971, 2000, Judd & Skean 1994, Judd et al 1995, Judd 2007.

The pattern of morphological variation in Miconia subcompressa, a species endemic to the mountains of southern Hispaniola, is assessed by a consideration of numerous herbarium specimens (many collected by the authors) and a phenetic (Principal Components) analysis of 14 vegetative characters, and morphological entities are compared with a phylogenetic hypothesis based on nrDNA-sequence variation (ITS, ETS) including several accessions of this species (from across its geographic and elevational range) as well as related species of Miconia sect. Chaenopleura, especially those of the Massif de la Hotte, Haiti. Our morphological data, incorporating recently collected herbarium material, indicate that the populations of M. subcompressa from the Monteada Nueva region (= Loma Trocha de Pey) are diagnosable morphologically from those of the Massif de la Selle and Massif de la Hotte, and these plants are described here as Miconia subcompressa subsp. beverlyana. Additionally, this study supports the recognition of the populations from moist pine forest/cloud forest habitats of the Massif de la Hotte, occurring mainly from 1450-2300 m, as M. subcompressa subsp. plumieri (= M. plumerii, sic). Finally, Miconia subcompressa may be paraphyletic, as preliminary molecular evidence suggests that M. xenotricha may have arisen within its phylogenetic structure. ResumenEl patrón de variación morfológica en Miconia subcompressa, una especie endémica de las montañas del sur de la Española, está revisado considerando numerosos especímenes de herbario (muchos colectados por los autores), un análisis fenético (Componentes Principales) de 14 caracteres vegetativos y las entidades morfológicas están comparadas con una hipótesis filogenética basada en datos moleculares (ITS, ETS) que incluye varias accesiones de M. subcompressa (de todo su rango geográfico y de elevación) y otras especies de Miconia sect. Chaenopleura, especialmente las especies del macizo de la Hotte, Haití. Nuestros datos morfológicos, los cuales incorporan colecciones recientes, indican que las poblaciones de M. subcompressa de la región Monteada Nueva (=Loma Trocha del Pey) son reconocibles morfológicamente de las poblaciones del macizo de la Selle y del macizo de la Hotte, y aquí están descritas como Miconia subcompressa subsp. beverlyana. Adicionalmente, este estudio apoya el reconocimiento de las poblaciones de los hábitats del bosque de pino húmedo/nuboso del macizo de la Hotte, que ocurre mayormente de 1450-2300 m, como M. sucompressa subsp. plumieri (=M. plumerii, sic). Finalmente, es probable que la especie Miconia subcompressa es parafilético, dado que evidencia preliminar de datos moleculares sugiere que M. xenotricha se originó adentro de la estructura filogenética de M. subcompressa.JUDD ET AL. 62 • Phytotaxa 197 (2)

Calycogonium formonense, a new species, is here described from the floristically diverse Massif de la Hotte of southern Haiti. It is compared to C. hispidulum, to which it is likely related. Although the genus Calycogonium is not monophyletic, C. formonense and C. hispidulum are probably related to other species, e.g., C. calycopteris, C. heterophyllum, and C. reticulatum, that exhibit reduced inflorescences and 4-merous flowers having hypanthia with four conspicuous lobes separated by longitudinal grooves and external calyx lobes that are flattened parallel to the floral radii. These distinctive species may form a clade. Calycogonium formonense is distinguished from C. hispidulum by its smaller leaves with the tertiary veins not raised on the abaxial surface, with entire margins (i.e., margin without elongate multicellular hairs), and usually solitary flowers.
