SOUTH AFKICAN FERN NOTES. 279 



Further investigation is also I'equired as to' the relationship 

 oi Asplctiium cylcsii, Sim; .4. pumilitni, Sw. ; and A. marlothii, 

 Hieron, a. group not yet sufficiently well known. 



Concerning Dryopictis patens, O. Kuntze, C. Christensen, 

 in "A Monograph of the Genus Dryapteris," Part I., 1918, 

 page 177, writes: " Specimens from Africa and Polynesia are 

 often determined D. patens; this species is, however, no' doubt 

 confined to America; the Polj'nesian plant is partly D. Harvcyi 

 (]\Iett) and partly D. Brackenridgei' (Mett) ; the African D. Ber- 

 giana (Mett), and D. Gueintziana (Mett)." 



Concerning Elapltaglossn}n lincare (Fee), ^loore, I may 

 mention that through a slip it is wrongly described in the synopsis 

 in " Ferns of South Africa," page 285, as having fronds two inches 

 wide; this should be ^in. to ^in. wide. 



Collections of ferns received from Kilimandjaro and jNIount 

 Meru, and from the bamboo- zone of Mount Elgon, Uganda 

 (7,000 ft. to 9,000 ft.), demonstrate that most of the common 

 ferns there are also Ehodesian, and that probably 90 per cent, of 

 all species of Pteridophyta found tliere occui- in Soutli Africa also.
