  1. Alangium kurzii Craib, Kew Bull.

Pelser (18-Jan-20): not reported from the Philippines by Bloembergen (1935).
  2. Alangium ridleyi King, J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 71 (1902) 78; De Wilde & Duyfles, Blumea 62 (2017) 45; Type: from Singapore (lecto). Distribution: Borneo, Malay Peninsula, ?Philippines, Singapore, Sumatra, Thailand. ?MINDANAO: Zamboanga del Norte. Notes: Note by Pieter B. Pelser & Kean Roe Mazo (9-May-21): The photos presented here are of a specimen that is part of the Alangium oblongum species complex and blurs the distinction between the three species in this complex, i.e. Alangium meyeri, Alangium oblongum, and Alangium ridleyi. Its leaves are quite a bit larger than those of Alangium meyeri and also has more robust twigs, and in fact seem to match those of A. ridleyi better. Also the petals seem a bit too large for Alangium meyeri. However, the plant does not match Alangium ridleyi well in some of the flower characters: its anthers seem considerably smaller and the length of the styles matches Alangium meyeri better than Alangium ridleyi and Alangium oblongum. Perhaps it would be better to adopt a more broadly delimited Alangium ridleyi of which Alangium meyeri and Alangium oblongum would be considered synonyms.
