the Palazzo rooga La Mortola, sr has the largest collection of these 
plants on the Riviera to pay him a visit. I stayed at his house more 
na eek, and had therefore full opportunity of studying all the 
forms Sabet in his collection in a leisurely manner; and he kindly 
also took me to a ae of other gardens at Mentone, Monte Carlo, 
Bordighera, and San Rem I also went with him to Genoa to see the 
magnificent botanical institute which he has recently founded there, 
and had the opportunity of going = ue ofessor Penzig through the 
Genoa botanic garden. I worked a day making notes upon the

Å. pers Salmdyck. Grown Se ei all along the Riviera, 
from Hyères to Genoa, in a great variety of forms, flowering freely. It 
does sa difer. materially from the plant of English conservatories. It 
is quite clear that A. filamentosa, Salmdyck, is a mere form of the 
same species, 
A. schidigera, Lemaire. La Mortola. This is just the plant of English 
ayong s. It is very doubtful whether this is more than a variety 
o 
Group MARGINATÆ.
