4.1.35. Macropsychanthus umbrinus (Elmer) L.P. Queiroz & Snak comb. nov.

Basionym: Dioclea umbrina Elmer, Leafl. Philipp. Bot. 1: 224. 1907. Type: Philippines, Leyte, Elmer 7249 (holotype: PHN; isotype: K! [000898375]).

Note.

In the protologue of the basionym, Elmer (1907) cited the type specimen as "9015, A. D. E. Elmer, Palo, Province of Leyte, Leyte, January, 1906". All of that information is on the label of the Kew specimen, although that label gives the collector number as 7249. As all of the other elements fit the protologue, we are considering the Kew specimen as an isotype.
