In Mitten's herbarium we find a specimen labeled Leskea micro- 

 carpa "fl. Ind. occ. Swartz. Hb. Hooker." This must have been 

 a manuscript name of Swartz, because it does not occur in his 

 flora Indiae occidentalis, as stated. It is evidently the type of 

 Sematophyllum microcarpum Mitt, which he placed in the section 

 Trichosteleum (p. 492), but it does not agree with other species 

 of this genus, because although there are occasional small obscure 

 papillae on a few of the young leaves, most of the leaves are 

 entirely smooth and the specimen agrees with Sematophyllum 

 xylophilum Mitt. (1. c. p. 490) to which it must be referred as 

 a synonym.
