摘要

描述和说明了两个新树种，Didelotia korupensis和Tessmannia korupensis(豆科，Caesalpinioideae)。Didelotia korupensis是该属的第12种。这是一种矮林树，高15米，茎部经常倾斜，直径30(-53)厘米。在喀麦隆Korup国家公园南部沿P样带的永久地块及其附近，仅在面积约4平方公里的区域内发现了Didelotia korupensis，迄今已记录了51棵树。根据IUCN的标准，korupensis被评估为濒危物种。Tessmannia korupensis是该属的第13种。它是一棵39米高的树冠树，茎直径105厘米。在Korup国家公园南部沿P样带的永久地块及其附近，以及在喀麦隆山附近的低地雨林中采集的单一集合中，已知的Tessmannia korupensis有7组，每组9到43棵树。根据世界自然保护联盟的标准，科鲁普塔斯曼尼亚被评估为濒危物种。

Didelotia korupensis and Tessmannia korupensis (Leguminosae, Caesalpinioideae), two new tree species from Korup National Park in Cameroon

Two new tree species, Didelotia korupensis and Tessmannia korupensis (Leguminosae, Caesalpinioideae), are described and illustrated. Didelotia korupensis is the 12th species in the genus. It is an understory tree to 15 m tall with an often leaning stem to 30(–53) cm diam. Didelotia korupensis is only known from an area of c. 4 km2 in and near the permanent plots along the P transect in the southern part of Korup National Park in Cameroon, where 51 trees have been recorded so far. Didelotia korupensis is assessed according to IUCN criteria as Endangered. Tessmannia korupensis is the 13th species in the genus. It is a canopy tree to 39 m tall with a stem to 105 cm diam. Tessmannia korupensis is known from seven groups of trees of 9 to 43 trees each, in and near the permanent plots along the P transect in the southern part of Korup National Park and from a single collection made in the lowland rain forest near Mt Cameroon. Tessmannia korupensis is assessed according to IUCN criteria as Endangered.
