Heterostemma collinum Schlechter (1913: 156) [15 Apr 1913]

TYPE:— PAPUA NEW GUINEA, ‘zwischen Gebüsch an Waldrändern bei der Kaulo-Etappe’, February 1908, R. Schlechter 17272 (B, destroyed) ; Schlechter (1913: 157), Fig. 11 A–K (lectotype here designated) ( Fig. 3 )

Notes. Heterostemma collinum was described based on specimen ’Nordöstl Neu-Guinea: zwischen Gebüsch anWaldrändern bei der Kaulo-Etappe, ca. 180 m ü. M. (Schlechter n. 17272.—Blühend im Februar 1908)’. The B duplicate is lost ( Hiepko 1978, Nicholas 1992) and no duplicates have been located. The illustration that accompanied the publication of H. collinum ( Schlechter 1913: 157 Fig. 11 A–K) is to be considered as original material and is here selected as lectotype.
