CHARACTERS OF TRIBES AND GENERA. 137 
than in these two genera, but even in that character 
there are instances of different degrees ot anastomo- 
sing found in the same or on different fronds of the same 
plant, therefore, setting aside the general acrostichoid 
character, Pecilopteris naturally associates with Meniscium, 
Fée refers sixteen species to this genus which in the 
“Species Filicum" are reduced to twelve, and in the 
“Synopsis Filicum” the species are placed under two 
sections, Gymnopteris and Chrysodium, which between them 
contain 36 species, part of which have no natural affinity 
with either the original species of Pecilopteris or Gymnop- 
teris; several even have articulate vernation and consequently 
belong to the division Eremobrya.

P. costata ( Wall.) ; P. punctulatum (Linn.) (v v.) ; P. flu-

The two latter are natives of Tropical West Africa, the 
others of India and Malayan region.

Vernation uniserial, sarmentum short or elongated,

feet high, pinns 6 to 8 inches in length, ovate lanceo- 
late, Primary veins costeform, venules compound
