摘要

摘要根据形态学证据，将圭亚那盾区一新种Terminalia L. (combretacae)描述为T. carinata Sabatier & J.Engel, sp. 11。这个新种经常被误认为是T. guyanensis Eichler，它与其他新热带终种的不同之处在于，它的叶下表面浅灰色，略带短柔毛，叶柄很长，果实有两个比身体宽的翅膀，明显是一面龙骨，另一面平。根据国际自然保护联盟(IUCN)的标准，对T. carinata Sabatier & j.e engel, sp. 11和T. guyanensis的保护状况进行了评估，并提出了对这两个物种的最不关注(LC)地位。

Terminalia carinata Sabatier & J.Engel, sp. nov. (Combretaceae), a new large tree species from the Guiana shield revealed by re-examination of material previously identified as T. guyanensis Eichler

ABSTRACT A new species of Terminalia L. (Combretaceae) from the Guiana shield is described as T. carinata Sabatier & J.Engel, sp. nov. based on morphological evidences. This new species was often misidentified as T. guyanensis Eichler from which it differs, as well as from other neotropical Terminalia, by its leaf undersurface palish-gray and slightly pubescent, quite long petioles and fruits with two wings wider than the body that is distinctly keeled on one face and flat on the other. An updated description of T. guyanensis is provided and the conservation status of T. carinata Sabatier & J.Engel, sp. nov. and T. guyanensis is evaluated according to IUCN criteria and a status of Least Concern (LC) is proposed for these two species.
