NATIVE COUNTRY OF ABVM CAKAKIENSE, 15i 
lato consideration llie distinct habit of the Trochodendrece as expressed 
by their serrated leaves, we shall have good evidence in favour of the 
above conclusions. 
It remains for me to express my thanlcs to Dr. Seemann, for kindly 
reminding me to examine the structure of the wood of Euptelia^ with 
the view of ascertaining how far it agreed with that of Ti^Qcltodendron 
described in my paper. In complying with his wish, I found that 
Euptelia had the usual structure of deciduous woods, — a close dotted 
prosenchyma, traversed by numerous net-like vessels without any ob- 
servable peculiarities, and without any special characteristies agreeing 
with those of TrocJiodendron, We have here the same evident diffe- 
i 
rences of anatomical structure as in the allied Winteracem between 
Illicium and Drimys, and an additional proof that botanical affiaities 
and internal structure do not always go together.

In an early number of the * Journal of Botany' (Yol. I. p. 25) was 
published a paper on Jriim Canariense, its introduction and successful 
cultivation as a starch-yielding plant in the Channel Islands, w^hich 
was of special interest to one who, for many years, has made the vege- 
tation of the Canary Islands his study. I may be allowed to supple- 
ment that paper by a few remarks on the supposed native country of 
the plant. I say emphatically supposed, as the only station recorded 
by Webb and Berthelot (*Phytographia Canariensis,' iii. p. 294) was 
calculated to raise some doubts respecting it.
