Chromosome Numbers in Pteridophyta— Brownlie 
495 
Loxsoma 
The rather isolated position of this genus has 
been accepted in most classifications where, in 
association with the Central American Lox- 
somopsis, it is elevated to the position of a dis- 
tinct family. Cytologically this genus appears to 
be related to the older section within Lindsaea. 
Also to this group probably belongs the genus 
Leptolepia, with a chromosome complement of 
n = c.47 (Brownlie, 1961). 
T eratophyllum 
This genus was placed in close association 
with Bolbitis and Elaphoglossum by Holttum
