摘要

Three new species of Gladiolus L. are described from South Africa.? G. dolichosiphon is the second known member of series Blandus from the mountains of the Little Karoo in Western Cape, and is distinguished from other members of the long tubed, pink-flowered G. carneus complex by its 5 or 6 linear leaves, creamy pink to salmon flowers with a tube 30-50 mm long and longer than the dorsal tepal, and its late summer flowering. G. karooicus from the Klein Roggeveld and the northern foothills of the Witteberg, is a spring-flowering species allied to G. permeabilis but has bright, canary-yellow flowers with the lower part of the lower tepals involute and conspicuously auriculate.? G. reginae is an edaphic endemic of the Sekhuk- huneland Centre of Floristic Endemism in Mpumalanga, and flowers in autumn. It is evidently a glabrous member of section Densiflorus series Scabridus, distinguished by its long-tubed flowers, streaked with red on the lower tepals and blotched with red in the throat. Anomalously, however, it has the tubular inner bracts and large capsules diagnostic of section Ophiolyza series Oppositiflorus. A re-examination of the morphology suggests that series Scabridus is better placed in section Ophiolyza and a slightly revised classification of Gladiolus in southern Africa is proposed. We also propose the replacement name G. sulculatus for the Tanzanian species, G. sulcatus Goldblatt, a later homonym of G. sulcatus Lam. Finally, a recent sighting of what appears to be G. rubellus from northern Namibia constitutes the first record of this species in the country and a major range extension from its previous known occurrence in southeastern Botswana.

Allemabilis结盟的春天开花的物种，但有明亮的金丝雀黄色的花朵，下部的花被片渐渐开出，明显地无耳。 G. reginae是姆普马兰加（Mpumalanga）的Sekhuk-huneland植物特有种中心的特有种，秋天时开花。它显然是Densiflorus系列Scabridus的无毛成员，以长管花为特征，在下部的花被上有红色条纹，在喉咙上有红色斑点。然而反常的是，它具有管状的内部片和大的胶囊，可以对Ophiolyza系列对生的Ophiolyza系列进行诊断。形态学的重新检查表明，刀ab鱼系列更好地放置在蛇形目部分，并建议对南部非洲的唐diol蒲进行稍作修改的分类。我们还为坦桑尼亚物种G. sulcatus Goldblatt提供了更名为G. sulculatus的替代名称，G。sulcatus Lam的后来同名。最后，最近从纳米比亚北部发现的红假单胞菌构成了该物种在该国的第一个记录，并且是其先前在博茨瓦纳东南部已知的大范围延伸。
