  Note: Rolfe (in Fl. Trop. Afr. 7: 89, 1897) remarked that “Durand & Schinz (Consp. Fl. Afr. V. 29) confound this [= Lissochilus malanganus] with the quite different L. malangensis Reichb. f.”. This is also the case in Fl. Cameroun 35: p. 610, plate 255 p. 611, 2001. The drawing (pl. 255/F-I) was made from specimen Baum 564, collected in S Angola on the Jonkoa (“am Jonkoa”), at 1150 m alt., in sandy soil, flowering on 21st December 1899. This specimen figures under Eulophia malangensis (Rchb. f.) Schltr. in Warburg, Kunene-Sambesi-Expedition H. Baum: p. 218, 1903. However, E. malangensis (Rchb. f.) Schltr. is a synonym of E. livingstoneana (see above under that species). On the other hand, Figueiredo & Smith in Plants of Angola: 190-191, 2008, do not quote specimen Baum 564 in their list of Eulophia. The lip represented in Fl. Cameroun 35: pl. 255/F, 2001, does not correspond with that of E. malangana, and also not with the lip of E. livingstoneana. If the Fl. Cameroun drawing was really made from Baum 564, the flower lip rather resembles that of E. holubii (cf. Fl. Afr. Centr., Orchid. 2: pl. 98/8 on p. 631, 1992). The latter species occurs in, i.a., Angola and adjacent Botswana-Zambia, and its presence “am Jonkoa” is not excluded.
