Sagraea 分支（Melatomataceae，Miconieae 部落）被简要描述、典型化，并被正式视为 Miconia 内的一个部分。此外，还有米康教的两个新种。 Sagraea 是海地西南部多样化植物区系的 Massif de la Hotte 特有物种，是在对本节加勒比物种进行系统修订的过程中发现的，在此进行了描述和说明。 Miconia hottensis 和 M. navifolia 形态相似，可能是姊妹种，我们将它们彼此进行比较，并与广泛分布的加勒比海物种 M. capillaris 和多米尼加共和国西南部特有的 M. tetraptera 进行比较；这四个物种共享矩形茎，具有四个低脊或翅，以及细小、短茎、盾状或拟盾状毛，并且可能形成一个分支。
The Sagraea clade (Melastomataceae, tribe Miconieae) is briefly characterized, typified, and formally treated as a section within Miconia. In addition, two new species of Miconia sect. Sagraea, endemic to the floristically diverse Massif de la Hotte of southwestern Haiti and discovered during the course of a systematic revision of the Caribbean species of this section, are here described and illustrated. Miconia hottensis and M. navifolia, morphologically similar and possible sister species, are compared to each other and to the widespread Caribbean species M. capillaris and the southwestern Dominican Republic endemic M. tetraptera; these four species share rectangular stems with four low ridges or wings and minute, short-stalked, peltate or pseudopeltate hairs and likely form a clade.
