NOTES

Thériot (1925) reported the genus Racomitrium Brid. as new for Madagascar based on collections by H. Perrier de la Bâthie from Mont Tsaratanana. Thériot reported these plants as “ Rhacomitrium Lepervanchei Besch. forma.” and they have subsequently been reported as Racomitrium crispulum var. tasmanicum (Hampe) E.Lawton ( Crosby et al. 1983) following the synonymy proposed by Lawton (1973). At the species rank (still following Lawton’s synonymy) the correct name for this taxon would be Bucklandiella membranacea (Mitt.) Bedn. -Ochyra & Ochyra and this was the

name reported in Marline et al. (2012). However, one of the Perrier de la Bâthie collections that form the basis of Thériot’s report (PC0708099, not seen) was annotated by R. Ochyra in 1997 as Racomitrium subsecundum (Ochyra in Ellis et al. 2020). In addition, we can report this same species (confirmed by H. Bednarek-Ochyra, in litt.) from the Andringitra region much further to the south. Based on this we believe it is safe to exclude Bucklandiella membranacea from the Malagasy flora and replace it with Bucklandiella subsecunda .
