Votomita roraimensis Morley (Memecyleae, Melastomataceae), nuevo registro para Venezuela
Leyda Rodríguez,Omaira Hokche
Ernstia , 2009,

Abstract: El género Votomita, tribu Memecyleae, agrupa árboles o arbustos con hojas simples, pinnatinervias, opuestas, usualmente glabras, flores tetrámeras en cimas de 1-3 flores, axilares. Incluye 10 especies con distribución Pantropical, reportándose para Cuba, Panamá, Guyana, Guayana Francesa, Surinam, Brasil, Perú y Venezuela. En el país se conocían dos especies endémicas, V. orinocensis y V. ventuarenis. Este trabajo tiene como finalidad documentar la presencia de Votomita roraimensis por primera vez para Venezuela, la cual se había reportado para Roraima, Brasil. Como resultado de recientes exploraciones botánicas en la cuenca media del río Cucurital, afluente del río Caroní, estado Bolívar, se encontró material vegetal de Votomita con características morfológicas diferentes a las de las especies venezolanas conocidas. Se analizó la morfología de las muestras botánicas y se consultó literatura pertinente. Posteriormente se corroboró la identificación mediante comparación con la descripción original de la especie y consulta de fotografías del tipo vía Internet. V. roraimensis se diferencia de V. orinocensis por presentar cuatro lóculos y numerosos óvulos; la presencia de estambres libres, pecíolos más cortos, hojas y frutos más peque os permiten distinguirla de V. ventuarensis. Se presenta la descripción de V. roraimensis y una clave para las especies venezolanas de Votomita. The genus Votomita, tribe Memecyleae, comprises trees or shrubs with simple, pinnately-veined, opposite, usually glabrous leaves, flowers 4-merous in axillar cymes with 1-3 flowers. It includes ten species with Pantropical distribution, including Cuba, Panama, Guyana, French Guiana, Suriname, Brazil, Peru and Venezuela. In this country two endemic species were known, V. orinocensis and V. ventuarenis. This paper documents the presence of Votomita roraimensis for the first time in Venezuela, previously known only from the State of Roraima, Brazil. As a result of recent botanical explorations in the middle Cucurital river basin, an affluent of the Caroní river, Bolívar State, material of Votomita with morphological traits different from the known Venezuelan species was found. The samples were analyzed by taxonomical techniques, compared with herbarium specimes,and by consulting specialized literature. The identification was corroborated by comparison with the original description and with the images the type of V. roraimensis, available in Internet. V. roraimensis differs from V. orinocensis in having four locules and numerous ovules; the presence of free stamens, shorter petioles, and s
