摘要
Microlicia crenatifolia产自巴西东南部著名的植物特有性热点地区--迪亚曼蒂纳高原。这种植物的特征是叶片较小(长达 8.3 毫米),叶片上有明显的细圆齿或轻微锯齿,花梗较短(长 0.7-1.0 毫米),萼裂片呈线形,外部有腺刺,上面覆盖着 0.1-0.3 毫米长的短腺体。我们提供了线图、叶片、种子和毛被的扫描电镜照片、分布图以及 M. crenatifolia 和假定亲缘植物(M. canastrensis、M. pabstii、M. serratifolia 和 M. thomazii)的识别钥匙。
Microlicia crenatifolia (Melastomatacae), a new species from the westernmost limits of the Diamantina Plateau, Minas Gerais, Brazil
Microlicia crenatifolia is described from the Diamantina Plateau, a well-known hotspot of plant endemism in southeastern Brazil. It can be recognized by its small leaves (up to 8.3 mm long) that are conspicuously crenulate to slightly serrate, short floral pedicels (0.7–1.0 mm long), and linear calyx lobes that are externally glandular-punctate and covered with short gland-tipped trichomes 0.1–0.3 mm long. We provide line drawings, SEM photos of leaves, seeds and indumentum, a distribution map, and an identification key to M. crenatifolia and putative relatives (M. canastrensis, M. pabstii, M. serratifolia, and M. thomazii).
期刊介绍:
The Journal of the Botanical Research Institute of Texas, formerly called Sida, Contributions to Botany, publishes research in classical and modern systematic botany—including studies of anatomy, biogeography, chemotaxonomy, ecology, evolution, floristics, genetics, paleobotany, palynology, and phylogenetic systematics. Geographic coverage is global. Articles are published in either English or Spanish; an abstract is provided in both languages. All contributions are peer reviewed and frequently illustrated with maps, line drawings, and full color photographs.
