Q. Lusitanica, Lam. It has been the fate of this remark- 
able tree to have been overlooked for more than two hundred 
years after the time of Clusius, and then to have been almost 
simultaneously rediscovered and described under a multitude 
of names by various authors. This too is the more singular 
as regarding a tree which produces an object of primary im- 
' portance, namely, the gall-nuts of commerce. Clusius indeed 
remarks, *galli autem extremis ramulis nascuntur, iisque in 
officinis venales reperiuntur, perquam similes, and in fact 
when compared with the Quercus infectoria, both as originally 
collected by Olivier, and as found by Labillardiére in Syria, 
and by myself and M. Parolini in Phrygia, the Spanish 
plant turns out to be identical with the Levant species, whose 
product is so universally employed. This oak begins to 
appear both in the eastern and western portion of the old 
world between the forty-first and forty-second degrees of 
northern latitude. It does not seem to pass the Pyrenees in 
the west, and I found it to the east to the north of Constan- 
tinople in the valley of Domoüz Deréh, which opens on the 
Black Sea. How much farther northwards in this direction 
I am unable to say. It descends as far south as Syria, but 
how far it follows in the west the chain of Mount Atlas can- 
hot be yet ascertained. It is not indigenous in the Canaries, 
but as well as the chestnut trees has been introduced’ by the 
Spanish colonists.”—5. Q. Hispanica, Lam. This is the 
famous oak cultivated in this country as the ** Luccombe,” 
Or * Exeter” oak.—III. Irices. 6. Q. Suber. T. Q. Ilex, 
L. 8. Q. Ballota, Desf. “ Clusius confounds this species 
with the Ilez, though the figure of his Ilex major, (Mar. Pl. - 
Hisp.), evidently belongs to Ballota. Lamarck first mentioned 
a variety of this plant with entire roundish leaves such as it oc- 
curs frequently under thename of Q. rotundifolia. Desfontaines 
described the species accurately, and the name he gave it is 
far preferable to that of Lamarck, which refers to a peculiar 
form of the plant, to which alone it should remain attached. -
