Cryptangium C. M., 1843, should fall on account of a homonym of 
Schrader’s, used in the Cyperaceae, in 1842. Cryptocarpus C. M. is 
replaced by Austin’s name for a genus of Hepatics. Decodon (C. 
M.) Broth. is antedated by a synonym, Rhachithecium Broth. and by 
a homonym of Gmelin, used for a genus of Lythraceae in 1791. 
Lasia P. B., 1805, is antedated by Lasza -Lour., 1790, in the 
Aroideae, and should be replaced by Forstromia, Lindb., 1862. in- 
cluding F. Ohioensis (Sull.) Lindb. (Leptodon trichomitrium Mohr.) 
Mniopsis Mitt., 1860, is attended by two homonyms: one of Du- 
mortier, in the Hepaticae> the other of Martius in the Podos- 
temaceae. 
Three genera of Phanerogams are displaced by homonyms in 
mosses. They are Hedwigia Swartz, 1788, Burseraceae, by Hed- 
wigta Ehrh., 1781. Sporledera Bernh., 1842, Pedaliaceae, by Sfor- 
ledera, Hampe, 1827. Swartzia Schreb., 1791, Leguminosae, by 
Swartzia Ehrh., 1787. A table of hononyms in Bryophyta and 
Spermatophyta is given, and a long list of works he has consulted. 
There is also a complete index. 1n many cases the original cita- 
_ tions are quoted, which renders this criticism of particular value to 
those who cannot verify the original descriptions.
