摘要：记述了产于西非几内亚的蝴蝶科唐菖蒲属一新种。该新种被归入唐菖蒲组。Decorati Goldblatt，并与该地区已知的9个物种进行了比较。开花植物高28-160厘米，开1-6朵明亮的橙色花，一次开一朵。对该新种的生态进行了详细的讨论，并对该地区的植被进行了描述。目前，只有在加勒比地区Kounkan Massif的两座无人居住的砂岩台山上才能发现唐菖蒲。在海拔650-1100m的石质土壤上发现了约210种植物，其中大多数植物(约160种)分布在无火灌丛中，每块1-4公顷，以火敏感植物为主，但草本植物很少。唐菖蒲似乎很容易受到草原火灾的影响。占地面积为28平方公里。该物种被评估为IUCN濒危物种类别。引文：Burgt X.M.van der，Konomou G.，Haba P.M.&Magassouba S.2019：剑兰属(蝴蝶科)，来自几内亚库恩坎山丘无火灌丛的一新种。-Willdenowia 49：117-126。DOI：https://doi.org/10.3372/wi.49.49112版本的Record于2019年4月17日在网上首次发布，2019年4月刊将纳入其中。
Abstract: Gladiolus mariae Burgt (Iridaceae), a new species from Guinea, West Africa, is described and illustrated. The new species is placed in Gladiolus sect. Decorati Goldblatt and compared with the nine species already known from that section. Flowering plants stand 28–160 cm high with 1–6 bright orange flowers, opening one at a time. The ecology of the new species is discussed in detail, and a description of the vegetation in the region is provided. Gladiolus mariae is at present known only from two uninhabited sandstone table mountains in the Kounounkan Massif, Forécariah Prefecture. About 210 plants were found, on rocky soils at altitudes of 650–1100 m. The majority of plants, about 160, were found in fire-free shrubland, in five patches of 1–4 ha each, dominated by fire-sensitive plant species, but grasses are infrequent. Gladiolus mariae seems vulnerable to grassland fires. The area of occupancy is 28 km2. The species is assessed to the IUCN category Endangered. Citation: Burgt X. M. van der, Konomou G., Haba P.
