Ohio, where he occasionally took me to see some illustration of 
the non-attachable forms. I could see nothing but a mere condi- 
tion. Plants that would not cling, as it was said, at Dayton, Ohio, 
clung well enough for me after I brought them here. At Cleve- 
land I was taken by some friends to see a kind that was said not 
to cling, and the grape-vine-like tendrils it was producing, freely 
commented on. But I pointed out a branch that had found 
out an old post for a friend, which was climbing by disk-attach- 
ment. There is about the same relation between these two forms 
as between Rhus radicans and Rhus Toxicodendron, when there is 
something it likes to attach itself to, it suits its habits to the fact,— 
and does not when the circumstances are repugnant. We might 
with as much reason say there are three forms of Ampelopsis,— 
for when it finds a dead tree to run on, it throws out a mass of 
annual rootlets along the stem, precisely as Rhus radicans does. 
It would probably do so under other conditions, though I only 
remember the rootlets on these rotten trees. That there are 
variations worth noting as distinct varieties, I have long thought 
probable. The Horse-chestnut-like foliage common to the Am- 
pelopsts as we see it along the great lakes, impresses ‘one at a 
glance as being distinct from the narrower, and less regularly 
toothed forms further south.

Botanical Notes. 
Hlooker's Icones Plantarum, the third series, now being pub- 
lished by means of a legacy left for the purpose by Mr. Bentham, 
are to be edited hereafter by Professor Daniel Oliver. Vol. xi. 
is devoted to Indian orchids, Vol. x. being in course of publica- 
tion at the same time. Only 250 copies are printed, and it would 
be well for American libraries to secure the work before the edi- 
tion is exhausted, after which this valuable serial will be difficult 
to obtain. The subscription price is very low, considering the 
expense of drawing and engraving, 100 plates of new or rare 
_ plants being produced annually.
