Genus and species published first in Flora of British India 5: 189. 1886 as Hexapora, with a brief description (and therefore validly published?). However, J.D. Hooker soon realized his mistake (there are 6 stamens with 2 pores each, thus 12 pores, not 6) and changed the name to Micropora. In some copies (such as the one in HBG) even p.189 has been corrected, but the index still lists the name Hexapora for p.189 and 862. On p. 862 the genus and the species are formally described as Micropora, citing in synonymy "Hexapora curtisii, p.189 of this volume." According to Kochummen 1989 (under Hexapora): "collected only from Penang Hill at about 300 m." According to Richard Chung, personal communication to Jens G. Rohwer, 19 Nov 2010, there is no material of this genus in KEP, and Kochummen had seen nothing but the type. According to Khoon Meng Wong, personal communication to Jens G. Rohwer, 19 Nov 2010, there are 9 sheets in SING: Curtis 524, Dec 1885, Penang, close to Chalet, 1000 ft. (Herb Hort Bot Sing acc. no. 066470) Curtis 1214, March 1890, Penang, Government Hill.
