EvANS: TAXILEJEUNEA PTEROGONIA 133 
Other allusion to T. debilis in the literature add very little to 
our knowledge of the species. Gottsche* mentions it briefly in 
connection with his Omphalanthus laevis and O. leioscyphus from 
Colombia, and Spruce,} in connection with his Lejeunea (Taxi- 
Lejeunea) chimborazensis from Ecuador. It is listed also, without 
comment, by Bescherellet from Martinique, by Duss|| from the 
same island, and by the writer from Peru.$ Several of the speci- 
mens recorded from the French Antilles have been verified. 
Although the species is known from so many of the Lesser Antilles 
it is not listed by Spruce {] in his account of the Hepaticae collected 
by W. R. Elliott on the islands of Dominica and St. Vincent.. 
It is rather remarkable that it has not been found on the latter 
island since the time of Guilding. 
T. martinicensis, which is here included among the synonyms 
of T. debilis, was based on material collected by L’Herminier on 
the island of Martinique. When Stephani published it in 1896 
he made no mention of Gottsche as author, but in his Species 
Hepaticarum (5: 472), seventeen years later, he cited ‘‘Omphalan- 
thus martinicensis Gottsche ms.”’ asasynonym. Strictly speaking 
this name is not wholly a manuscript name. It was published in 
1864 by Gottsche (as already noted in the synonymy), in connec- 
tion with his Omphalanthus leioscyphus from Colombia. Although 
he gave no formal description of his O. martinicensis he distin- 
guished it from O. debilis (to which he considered it allied) by its 
smooth perianth and entire bracts, and also pointed out numerous 
differencés between O. martinicensis and O. leioscyphus. The 
name O. martinicensis appears also in Husnot’s catalogue of the 
bryophytes collected in the French Antilles, where the specimens 
distributed in his ‘‘ Plantes des Antilles’ are enumerated.** These 
specimens were determined by Gottsche and the one issued under 
the name O. martinicensis presumably agrees with L’Herminier’s 
type. Although Gottsche apparently knew his species from
