36 ON THE GALLS OF TEREBINTHUS AND PISTACIA. 
velopment of a flowering bud, still retaining at its base ves- 
tiges of scales impregnated with a resinous juice. From the 
base, the pierced bud appeared to divide into three or four 
branches, each bearing a gall ; but of these galls there only- 
remain one entire, and a portion of a second. The entire 
gall, in rising from the peduncle, is enlarged rapidly into a 
fan-shape, and separates itself near the middle in two unequal 
parts, on which are prominent points indicating other divi- 
sions less marked, or more completely merged and con- 
founded. The greatest length of the gall is forty-seven 
millimetres, and its maximum breadth thirty-two. This gall, 
when fresh, must have been covered with a yellowish down, 
which remains in the hollow places, while the prominent 
parts have become brown and polished by friction. The 
substance of the gall is rather more than a millimetre in 
thickness, whitish, and translucid in its fracture, and so com- 
pact and gorged with juice, that it presents, when cut, the 
appearance of a dried gum-resin. It has no reticulated ex- 
udation, and possesses a very astringent taste, without any 
resinous flavor or smell. 
The gall fragment, which was sent me by M. Ledanois, 
only differs from that which I have just described, by its uni- 
form dull greyish-red colour. It has the same yellowish 
down on the exterior — the same compact, translucent, and 
whitish substance within, and the same astringency, without 
aromatic or resinous taste. Some small entire galls which 
are with it, resemble the small angular excrescences in the 
figure of Lobel {Adversaria, p. 412;) however, they differ 
from the black horn-shaped gall above described (the 2d 
sort.) 
It is evident that this third gall is the most important of 
the three, from the large proportion of tannin which M. 
Ledanois has found in it. It is to be regretted that it is so 
rare, and so little known. 
Idib.
