TYPE:— PHILIPPINES, Luzon, Batangas, February 1915, A.D. Merrill species Blancoanae 807 (neotype K, here designated, isotype L [L2720409], BM)

Notes: — Heterostemma cuspidatum is based on Cuming 1449 in P ( Decaisne 1844). P houses two duplicates of Cuming 1449 [P03899073, P03899078]. The best-preserved sheet, [P03899078] is selected as lectotype of H. cuspidatum .

Blanco collected very few specimens and none are available for S. quadrangula ( Merrill 1918) . Merrill’s interpretation of S. quadrangula as a synonym of H. cuspidatum is accepted and Merrill’s specimen (Merrill species Blancoanae 807 (K)) is selected as neotype for S. quadrangula .
