Checklist and typification of Heterostemma (Apocynaceae, Asclepiadoideae, Ceropegieae) Author Rodda, Michele text Phytotaxa 2016 2016-05-27 263 1 1 17 http://dx.doi.org/10.11646/phytotaxa.263.1.1 journal article 10.11646/phytotaxa.263.1.1 1179-3163 13671611 Heterostemma montanum Schlechter (1913: 158) [ 15 Apr 1913 ] TYPE:— PAPUA NEW GUINEA , Finisterre Range, 13 January 1909 , R. Schlechter 19057 ( lectotype K [K000894690], here designated, isotype BR [ BR 0000005211401], P [P03899068]) Notes: —The original material of H. montanum was indicated by Schlechter (1913) as ‘Nordöstl. Neu-Guinea: Liane in Nebelwäldern des Finisterre-Gebirges, ca. 1300 m ü. M. ( Schlechter n. 19057 blühend im Januar 1907 )’. The B material is lost ( Hiepko 1978 , Nicholas 1992 ) but duplicates are found at BR, K and P. Specimen [K000894690] is fertile and well-preserved and is therefore selected as lectotype of H. montanum .
