Abstract
A new species, Justicia darienensis T.F. Daniel & M. Vargas P., is described from a biodiverse “hotspot” in an isolated cloud forest of Darién Province in eastern Panama. It is compared to morphologically and palynologically similar species in southern Central America. Justicia darienensis is characterized by a complex inflorescence with heteromorphic (shape and fertility) bracts, white corollas with purple markings on the lower lip, glabrous anther thecae, 4-aperturate pollen, and pubescent capsules. Images of the plant and its pollen are provided.
新物种 Justicia darienensis T.F. Daniel & M. Vargas P. 描述于巴拿马东部达连省一个孤立云林中的生物多样性 "热点地区"。该物种与中美洲南部在形态学和古生物学上相似的物种进行了比较。Justicia darienensis 的特征是花序复杂，苞片异形（形状和生育力），白色花冠下唇有紫色斑纹，花药囊无毛，花粉 4钝，蒴果有短柔毛。本文提供了该植物及其花粉的图片。
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.
