          April 14th - Agrimonia eupatoria & Prunella vulgaris
from you appear just the same as ours. Aspidium
augustum I should consider distinct from
Aspelina folium however I may be wrong in
what I take to be the latter. I never saw
a Potamogeton like the one you have such.
Certainly it cannot be a variety of P. perfoliatus.
It is more near P. serratus which [Karl Ludwig] Willdenow
says has the leaves entire. I shd rather
suspect it is a new species.

I have mislaid my specimens of 
Calymperes hobsonii but will secure one
for you when I find them again.

Yrs faithfully
R.K. Greville
