be either entirely parenchymatic, or the cell walls may be thick- 
ened evenly, or even papillose. This character he made use of 
in describing six new species, but he ignored the spores and para- 
physes, so that it is hard to compare his species with those > 
scribed and figured by Fee. Luerssen * followed Mettenius in 
reducing V. Deppeana to V. filifolia, in spite of the differences of 
the scales as figured by Müller, and maintained V. curvidentata to 
which he referred V. graminifolia as a variety. 
GEOGRAPHICAL DISTRIBUTION 
In the following list the type locality is given first, and then 
the distribution as cited by Fée, the authors of the species and sub- . 
sequent lists, without any attempt to verify the determinations : 
V. lineata, Haiti; West Indies, North and South America, 
East Indies (?). 
V. graminifolia, Brazil; Peru, Mexico. 
V. stipitata, Peru; West Indies and South America. 
V. Gardneriana, Brazil; South America and Mexico. 
V. filifolia, Mexico; Central and South America, West Indies. 
V. Ruiziana, Peru and South America. (V. Moritziana, Peru.) 
V. scabrida, Brazil; Mexico. 
V. remota, New Granada, South America and West Indies. 
V. Karsteniana, United States of Colombia. 
V. gracilis, United States of Colombia. 
V. Orbignyana, Bolivia. 
V. longipes, Ecuador. 
V. intramarginalis, Jamaica. 
V. dimorpha, Mexico. 
V. curvidentata, Brazil. 
V. pachydictyon, South America, Surinam. 
V. Deppeana Mexico. 
Leaving out of consideration the South American species, it 
from Mexico and the West Indies. Of these the Mexican species 
are most interesting and need revision. V. scabrida and V. 
Deppeana have not been seen in any American herbarium. In V. 3 
scabrida Fée t gives the length as 90 cm.; this is probably a mis- 4
