invariably in an upright direction, and attaining tlie height of from 12-15 feet. At the 
base the circumference is equal to that of a man’s thigh, gradually tapering towards the 
top, where it shoots off its branches and leaves” (Pharm. Journ. and Trans. xii. 1853). 
As I saw this plant in Playfair's garden at Aden in September last, in young leaf and 
covered with bloom, I was much struck by its elegant singularity. : The long racemes of 
green star-like flowers, tipped with the red anthers of the stamens (like aigrettes of little 
stars of emerald set with minute rubies), droop gracefully over the clusters of glossy 
glaucous leaves; and every part of the plant (bark, leaves, and flowers) gives out the 
most refreshing lemon-like fragrance. 
It gave me the most lively pleasure to find the flowers which I had been so long seek- 
ing of so charming an originality, and in such a romantic spot; for Playfair's garden is 
a mere angle! in the shadow of two pumice rocks, which tower hundreds of feet above it, 
guarding in their shadows? the store of water for the garrison and town; and green 
leaves, shade, and water make Paradise in the east.

POSTSCRIPT. 
CARTER'S plant (** Maghrayt d'sheehaz ") was not before me when I was preparing this 
paper (see pp. 138, 139), and my description of B. Carterü was, and is, the description 
of * Mohr Madow. A flowering specimen of “ Maghrayt d'sheehaz ” was subsequently 
received from Mr. Gray, B.M., the present Director of the Victoria Gardens, Bombay, 
when it, was found that in it the stamens are inserted into the side of the disk, but it was 
_too late to add the character to the description of the species Boswellia Carterii and of 
the genus. This character therefore distinguishes the Arabian (Maghrayt d’sheeha:) 
from the Soumali (Mohr Madow) variety of B. Carterii.
