latitude, and continues to increase till, in the south, it is Ww 
far the most common species. It seems to make its appear- — 
ance in Greece in the same latitude, and is perhaps the treè — 
called Entanodrys and Hemeris by Theophrastus, but its — 
eastern station seems to need further investigation; for it is 
not impossible that the Hemeris of Theophrastus may belong 
to the varieties of Q, Robur, mentioned as eatable by Pro- 
fessor Tenore (Syll. page 469). The distinctions between — 
the Ilex and Ballota, are frequently little apparent in isolated 
specimens, but I observed that the peasant distinguished the 
two, accurately, at a distance, which I was for a long time 
unable to do. The leaves of Ballota have always a tendency . 
to assume a round rather than an elliptic form: toothed and 
entire leaves are mingled on the same branch, and the down —— 
with which they are clothed is much thicker and of a differ- _ 5 
ent quality, the branches are stiffer, and the fruit, besides 
being sweet, is very long and cylindrical. It is of a much 
less hardy nature than the Zez, which becomes a large forest 
tree when cultivated in England; whilst a Ballota which I 
preserved for near twenty years in a warm exposure, had 
scarcely reached six feet during that period.”—IV. Cocci-

Under Rhododendron Ponticium, L., (the common species 
of our gardens,) the author remarks, “this species originally s 
discovered by Tournefort in Pontus, was found likewise by — 
Labillardiére in Syria near Seyde. I have not had occasion — 
to compare the Spanish specimens with those of the original 
locality, but they are certainly identical with the Syrian 
plant. Thus it appears that under the same latitude the 
plants of the eastern extremity of the Mediterranean are 
reproduced in the west. The Cedar of Lebanon reappear- 
ing on the mountains of El Rif in Morocco, and the oak of 
the east which produces the gall-nut covering the hills of 
Spain, are other not less striking examples; whilst the sub-
