Summary During the preparation of a revision of the Cyrtandra terrae-guilelmi complex, endemic to Papua New Guinea, several new species were identified from material that had been misidentified as belonging to this group. Here, we formally describe two of these. Cyrtandra menyamyana S.Hatt & Bramley can be distinguished from all other Cyrtandra by its densely hairy whitish-cream to orange yellow flowers with corolla lobes in 2...

However, New Guinea Cyrtandra have not received a taxonomic revision since Schlechter in 1923, who recognised 14 sections. A taxonomic revision of the red-flowered Cyrtandra terrae-guilelmi K.Schum. species complex (within Schlechter’s Cyrtandra sect. Loxanthe ) is presente...

Species of Hydnora are characterised by their underground habit, unusual fleshy flowers and complete absence of leaves or photosynthetic tissue. This is the first detailed monograph of the genus Hydnora since 1935 and is informed by a comprehensive survey...

Summary We revise and update the records of strict and near-endemic species of the Bali Ngemba Forest Reserve, the largest known surviving patch (c. 8 km 2 in area) of submontane or cloud forest in the Bamenda Highlands, Cameroon which have lost >96 % of their original forest due to human activities. Nine strict endemics, and 11 near endemics are now documented, a drop from the number recorded after the first survey in 2004, s...
