subconvex verruce, but without any apical pore or epithecium, 
and are apparently separate, but in reality covered with a con- 
tinuous membrane or excipulum, concealed partially by the thallus, 
but seen in a vertical section to be a continuous green gru- 
mous mass. Each of the nodules, when viewed horizontally under 
the microscope, appears as a green grumous mass, in which the 
asci are circularly arranged. ` 
EXPLANATION OF PLATE VI. 
Fig. 1: a, lichen, natural size; 4, apothecium of clustered nodules, magnified 40 
times; c, nodule, viewed horizontally, magnified 170 times ; d, vertical sec- 
tion of nodule, magnified 170 times ;“e, spore, magnified under pressure 
1000 times. The small circular bodies to the left of the spore (e) are gonidia.

On the Determination of three imperfectly known S cies of 
Indian Ternstreemiacee. By W. T. Tutserron Drér, B.A.,

[Read April 18, 1872, and January 16, 1873.] 
Tur synonymy of the species of Ternstroemiacee contained in 
the catalogue of Dr. Wallich’s herbarium has become in many 
cases involved. This has been probably in a great measure the 
result of the misplacement of labels in the sets of specimens origi- 
nally distributed. It was almost inevitable that such a displace- 
ment should take place to some extent, inasmuch as the specimens 
corresponding to the several numbers in the catalogue were not 
kept separate in the distribution; on the contrary, they were 
often laid one upon the top of the other, the numbers being written 
on loose labels, the juxtaposition of which with the specimens 
might easily become disturbed. 
No great harm would result from this in cases where the type 
collection is available for correcting mistakes. It so happens, 
however, that Ternstroemiacee is one of the orders in the Walli- 
chian herbarium in which many of the type specimens are want- 
ing. They appear to have been sent abroad for description, and
