[Fournier, Joc. cit., describes three other species of Vilfa of which we have seen no 
specimens; they are:—V. liebmanni (Liebmann, without locality), V. pubescens (Cafion 
de las Minas, Karwinski), and V. sacatilla (San Luis Potosi, Virlet d’ Aoust, and Cha- 
pultepec, Schaffner). Vilfa orizabe, Rupr. in Bull. Acad. Brux. ix. reprint, is a naked 
name. | 
53. EPICAMPES. 
Epicampes, Presl, Relig. Henk. i. p. 235, t. 89; Benth. et Hook. Gen. Plant. iii. p. 1148. 
An exclusively American genus, ranging from California and Mexico to the Andes. 
Sixteen species have been proposed, but several of them are not, in our opinion, 
distinguishable as such. 
1. Epicampes berlandieri, Fourn. Mex. Pl. Enum., Gram. p. 89. 
SoutH Mexico, the city of Mexico (Berlandier, 670), Orizaba (Miller, 2130; Botteri, 
102; Schaffner), near Tacubaya (Schaffner). 
2. Epicampes bourgei, Fourn. Mex. Pl. Enum., Gram. p. 88, cum var. 
£. mutica. 
Sout Mexico, Escamala, Orizaba (Bourgeau, 2973), Mirador and Tlaltengo (Lied- 
mann). Hb. Kew. 
This is exceedingly near H. mutica, and perhaps, as well as E. expansa, should be 
referred to that species. 
3. Epicampes buchingeri, Fourn. Mex. Pl. Enum., Gram. p. 88. 
Sout Mexico, Orizaba (Thomas in herb. Buchinger). 
4, Epicampes expansa, Fourn. Mex. Pl. Enum., Gram. p. 88. 
South Mexico, Orizaba (Bottert). 
5. Epicampes gigantea, Fourn. Mex. Pl. Enum., Gram. p. 88. 
Sout Mexico, Rio Blanco, near Orizaba (Bourgeau, 3137). 
We have not seen Bourgeau’s number cited for this species, and the description of 
E. gigantea, as of most of the other new ones proposed by Fournier, is limited to two or 
three lines, so that it is impossible to deal with it without examining the type. The 
inference is that most of them are founded upon very slender characters, for all the 
Mexican specimens in the Kew Herbarium are referable to five or six species,
