CAUDALEJEUNEA 
In the subgenus Lopho-Leseunea as originally proposed Spruce 
included a Brazilian species which he called ZL. harpaphylla, 
remarking at the same time that it differed from the other mem- 
bers of the subgenus in several important respects. A few years 
later Stephani * proposed the subgenus Cauda-Lejeunea for the 
reception of L. harpaphylla and its allies. Meanwhile Spruce had 
also reached the conclusion that his species ought to be separated 
subgenerically from Lopholejeunea and suggested, in a paper by 
Pearson,} that it be made the type of a new subgenus, to which he 
gave the name Cadlistolejeunea. Since Stephani’s name was more 
formally published and clearly had the right of priority, it was 
used by Schiffner as the proper name of the group when he raised 
it to generic rank. 
Schiffner accredits eight species to the genus and enumerates 
seven of them by name. The omitted species is Z. (Cauda-Ley- 
eunea) Lehmanniana, which ought really to be considered the type 
Species because it is the first one mentioned by Stephani. Of the 
listed species three are from tropical America, two from Africa, one 
from various islands of the Pacific, and one from tropical Asia. 
L. Lehmanniana is also from tropical America. Stephani has 
Since added two species to the genus, one from Cuba and Brazil 
and the other from New Guinea, so that it now apparently con- 
tains ten species in all. The species from Asia, however, has 
Never been published except as a “omen nudum, and in the opinion 
of the writer the five so-called American species are simply forms

well-established spécies left in the genus. The American species,
