AND CAPPARIS MURRAYIT. 73 
I find, on reexamining my specimens, that the leaves of these 
plants differ in form, as well as in size and texture, and that the 
difference appears constant. 
C. galeata has broadly ovate leaves, which Dr. Anderson calls 
thick, and Decaisne cartilaginous, and which are entirely gla- 
brous even in their earliest stage; they are 2 inches long and 
lj broad. The leaves of Murrayii are orbicular, or nearly so, 
l inch long and 1 inch broad, very tender, almost membranous, 
and, in their young state, almost tomentose. 
The filaments, anthers, and pollen in C. galeata are white; in 
Murrayii these parts are purple. In the ovary of the former 
there are ten parietal placente; in that of the latter, only four. 
The peduncles in C. galeata are articulated with the stem, and, 
when they fall off, leave a circular scar, with a free smooth 
margin; in C. Murrayii there does not appear to be any articu- 
lation. 
These distinctions appear to be of essential value. 
Iam inclined to lay great stress on the improbability of a plant 
with two natural habitats, exhibiting in the desert one a degree 
of luxuriance to which it is a stranger in its other home in the 
tropical forest. If the circumstances had been reversed, it would 
be just what our experience of the effects of climate would 
induce us to admit. 
C. egyptiaca, which is also a native of Sind, has such a close 
resemblance to C. Murrayii that there is no difficulty in be- 
lieving them one and the same; but I must look on C. galeata as 
à very distinct species.

[From the printed descriptions and what materials are at 
Kew, it seems to me that Dr. Anderson was probably right in 
uniting Capparis galeata (Fresen.) and C. Murrayiana (not Mur- 
rayit), Grah. 
Mr. Dalzell lays much stress on the habit, size, &c. of this 
plant, in (1) Bombay proper and (2) Sind and Arabia, being the re- 
verse of what might be expected, on ordinary rules, as to the va- 
riation of a plant owing to more or less moisture; but these 
rules are not quite inelastic, or'always dominant. 
The various items touched on and expressed by Mr. Dalzell, 
with the views I have had to form on them, are these :—
