摘要

南越魔芋属(Amorphophallus kienluonggensis)一新种。它在形态上接近A. brevispathus Gagnep。(泰国)和A. prolificus Hett。&加洛韦(泰国)。然而，它不同于这两个物种的柱头有一个中央凹陷和一个倒锥状的雄性部分。到目前为止，a.k enluonggensis只在越南南部的Kien Giang省的Kien Luong地区被发现。这种植物生长在石灰岩山上，由于开采水泥制造，其栖息地受到威胁。因此，该物种可以在IUCN排名中被列为CR(“极度濒危”)。

Amorphophallus kienluongensis (Araceae), a new species from the Mekong Delta, Southern Vietnam

Amorphophallus kienluongensis is described as a new species from southern Vietnam. It is morphologically close to A. brevispathus Gagnep. (Thailand) and A. prolificus Hett. & A.Galloway (Thailand). However, it differs from both these species by a stigma with a central depression and an obconic male portion. So far A. kienluongensis is known only from the Kien Luong district of the Kien Giang province, southern Vietnam. The plant grows on limestone hills where its habitat is under threat owing to quarrying for cement manufacture. Therefore this species could be ranked as CR (‘critically endangered’) in the IUCN ranking.
