摘要

我们描述了巴西塞阿拉州的一个新物种:Wedeliafigueiredoana。它在形态上与 W.bonplandiana 相关,但区别在于叶片宽度为 0.25-1.05 厘米(vs. 1.5-2.6 厘米),叶片为线形至狭长圆形(vs. 椭圆形至匙形),总苞为 3 分裂(vs. 2 分裂),苞片长 3.9-4 毫米(vs. 6-7 毫米)。我们对胞果进行了解剖分析,并提出了一个更准确的术语来描述与蟛蜞菊相似的翅膀。我们还提供了该新种的科学图解、栖息地照片、其地理分布地图,并讨论了其分类亲缘关系,同时还提供了具有顶端明显翅片的蟛蜞菊种的分类检索表。

Wedeliafigueiredoana (Asteraceae, Heliantheae), a winged cypselae new species of Wedelia for Brazil.

We describe one new species from Ceará state, Brazil: Wedeliafigueiredoana. It is morphologically associated with W.bonplandiana, but distinguished by 0.25-1.05 cm leaf blade width (vs. 1.5-2.6 cm), linear to narrow oblong leaf blade (vs. elliptic to spatulate), 3-seriate involucre (vs. 2-seriate), and cypselae 3.9-4 mm long (vs. 6-7 mm). An anatomical analysis of cypselae is provided, and we propose a more accurate terminology to describe similar wings to Wedelia species. We also provide a scientific illustration of the new species, photos of habitat, a map of its geographic occurrence, and its taxonomic affinities are discussed with a taxonomic key to the Wedelia species with the apically pronounced wings in the cypselae.
