Dear Folks 
People from all over the world were so kind to send me some 
Cryptostephanus vansoni. showing the utility of Email. I have 
measured from all 6 Cryptostephanus vansonii the nuclear DNA 
content. One out of six is an odd value I like to have your comment 
please
no1. no2 from G. Duncan Kirstenbosch
no3 Ken Smith Australia
no4 fr Connie and James Abel S Africa
no5 ( pink form!) from J Waddick USA
All had nearly the same value 44.6 picogram DNA per nucleus. 
However a ""typical but large leaved  white flowering form of J 
Waddick had 36.4 pg  This suggests that it a = hybrid b.= a new 
species. It would have been simple if the pink form was the odd 
one ! Moreover a leaf of the other two species might trow some 
light here too!
