摘要

Dalea verticillata 是产自墨西哥瓦哈卡州的一个新种，该种被描述并绘制了插图。Dalea verticillata 与 D. filiciformis 相似，但其区别在于轮生叶片（与 D. filiciformis 的互生叶片相比），小叶数量较多（(31-)39-63(-69) vs. (11-)13-29(-37) ），托叶较长（4.5-8 毫米 vs. 0.3-3 毫米）。(11-)13-29(-37)），托叶较长（4.5-8 毫米对 0.3-1.5 毫米），反折（对上升），宿存（对落叶），顶生圆锥花序（对腋生总状花序），翅瓣近椭圆形（对卵形）。这是迄今为止单种亚属 Psoropteris 的第二个种，轮生叶片特征首次在 Dalea 属中被记录。

Dalea verticillata (Leguminosae, Papilionoideae, Amorpheae), una nueva especie de Oaxaca, México y segunda para el subgénero Psoropteris

Dalea verticillata is described and illustrated as a new species from Oaxaca, Mexico. Dalea verticillata is similar to D. filiciformis, but it is distinguished by having whorled leaves (vs. alternate in D. filiciformis), with a greater number of leaflets ((31–)39–63(–69) vs. (11–)13–29(–37)), longer stipules (4.5–8 mm vs. 0.3–1.5 mm), reflexed (vs. ascending), persistent (vs. deciduous), terminal panicle inflorescences (vs. axillary racemes), and the wing petals subelliptic (vs. ovate). This is the second species of the hitherto monospecific subgenus Psoropteris, and the whorled-leaf character is recorded for the first time in the genus Dalea.

期刊介绍： Since 1931, Brittonia, assuming the broadest possible definition of the field of systematic botany, has been an important outlet for the publication of original research articles on anatomy, botanical history, chemotaxonomy, morphology, paleobotany, phylogenetic systematics, taxonomy, and phytogeography. Each issue contains articles by the staff of The New York Botanical Garden and outside contributors, book reviews, and announcements.
