Crypsinus albidosquamatus (BL) Copel. 
Ilaga Valley, W. New Guinea 
n = 36 
( 1947 ) in a sub-family Lomariopsidoideae, and 
by Copeland ( 1947 ) close to these same genera 
in his family Aspidiaceae. Although the present 
count of n = c4Q is not certain, it supports 
this association. 
Blechnum 
The count of n = c.37 for Blechnum indi- 
cum appears somewhat unusual because previ- 
ously this genus appeared to have only two 
sections, one based on n = 28, the other on 
n = 33, 34. A greater variation in the base 
numbers gives the impression that the family 
may be older than has previously been thought. 
Other genera 
All remaining figures listed are in accord 
with previous records for these genera, the only 
two factors of interest being the constancy dis- 
played by the Hymenophyllaceae in New Zea- 
land, compared with the records from Asia, 
and the very high polyploidy of the New Cale- 
donian form of Psilotum nudum .
