Suborder VI. OPHIOGLOSSACEZ.. 
_ Besides the two genera represented in Mexico, there is one other, namely Helmin- 
thostachys, an Asiatic and Australian monotype. Presl’s Botryopteris mexicana is a 
synonym of it, and was by mistake published as Mexican. Fournier queries the latter 
as a synonym of Anemia phyllitidis. 
47. OPHIOGLOSSUM. 
Ophioglossum, Linn.; Hook. et Bak. Syn. Fil. p. 444. 
Almost universally spread, except in the arctic regions. Hooker and Baker reduce 
the numerous species described by various authors to ten. 
1. Ophioglossum palmatum, Linn. ; Hook. et Bak. Syn. Fil. p. 446; Eaton, 
Ferns N. Am. ii. p. 269, t. 81. figg. 11-14; Fourn. Mex. Pl. Enum. i. p. 141; Mart.

Sour Brazit and Perv; also in the SEYCHELLES and Bourson. Hb. Kew. 
Galeotti seems to have been the only collector who has met with this striking species 
in Mexico, and we have no record of it in Central America.
