Abstract

ABSTRACT Hyptidendron Harley, one of the 19 genera recognized for the subtribe Hyptidinae, has some of its species with a narrow campos rupestres (a Brazilian vegetational formation) distribution, often restricted to a single mountain range. We report a new species, Hyptidendron pulcherrimum Antar & Harley, sp. nov., endemic to a single mountain in the Serra do Padre Ângelo, a disjunct area of campos rupestres from where some new angiosperm species have been recently described. The new species is unique due to the morphological combination of flowers arranged in dichasial cymes, indumentum composed of curved, rigid, broad-based hairs, leaves petiolate, glabrescent and bullate, corolla tomentose, with the tube curved, 7.5-10 mm long and one slightly winged nutlet per fruiting calyx. The new species is compared with Hyptidendron vauthieri (Briq.) Harley the most similar species morphologically. We also provide a complete description, diagnosis, illustration, distribution map with the new species and closely related species, a photograph plate, and a preliminary conservation status assessment.

巴西米纳斯吉拉斯州的一种狭窄特有种:Hyptidendron pulcherrimum Antar & Harley, sp. 11 . (Hyptidendron pulcherrimum Lamiaceae)

摘要:哈利水蛭属(Hyptidendron Harley)是水蛭亚科(Hyptidinae) 19属之一，其部分种具有狭窄的campos rupestres(巴西的一种植被构造)分布，通常局限于单一山脉。我们报告了一个新种，Hyptidendron pulcherrimum Antar & Harley, sp. nov.，特有种在Serra do Padre Ângelo的一座山上，一个campos rupestres的分隔区，最近描述了一些新的被子植物物种。该新种的独特之处在于其形态组合:花排列在二重聚伞花序中，毛被由弯曲的刚硬的宽基毛组成，叶具叶柄，后脱落，具苞片，花冠被绒毛，筒部弯曲，长7.5-10毫米，每果萼有一个微翅小核。并将新种与水蚤(Hyptidendron vauthieri, Briq.)进行了比较。哈利是形态上最相似的物种。我们还提供了完整的描述、诊断、插图、新种和近缘种分布图、照片和初步的保护状况评估。
