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!
