membranous, infolded over the ovary, and adhering 
to the pentagonal disc-like stigma.  Pollen-masses

large disc-shaped stigma. 
We append a translation of Mr. Naudin's letter :— 
It із now some years ago that you sent me some 
seeds of Chlorocodon Whitei, I duly raised them, 
one plant, growing on a wall, h hem 
d sent time is 
covered with flowers and will — — ce seed, 
The heat just now is torrid, and the sunshine of 
Antibes rivals that of Natal or the Cape of Good 
Hope. I thought Mete you would be interested in 
seeing of my plant, and send you a piece 
of it, which I hope will arrive in a fresh condition,

Chloroe odon Whitei is a fine decorative plant, is 
worth cultivating as aclimber in any Orange-growing 
district such as France and North Africa. Thus, it 
grows perfectly at Oran, whither I some time ago sent 
some seeds to a plant-lover fond of acclimatising
