External characters. 
The trunk is simple, subexannulate, smooth in the lower 
and older parts, with the exception of irregular longitudinal 
fissures in the cuticle. In the later formed parts it is covered 
with the scars of the leaves, which scars of the leaves 
are arranged in indistinct annuli, the intermediate spaces 
being occupied by the remains of former inflorescences. 
No stress is to be laid on the annuli, which are by no 
means universal, and which when present, are very obsolete. 
The trunk is proliferous, each year producing 2 close rows of 
leaves and terminal inflorescence, which necessarily becomes 
pushed out by the succeeding formation of leaves. "These 
annuli may be traced from 5 to 7 formations, all traces of the 
scars of\the leaves becoming lost after that time, 
Dimensions: Erect, trunk 4 feet high, about a foot and 
half from its base, the circumference is 194 inches, and the 
diameter 5%, inches; across the last formed annulus 204 
inches : that of a trunk, 9 or 10 feet in length, (which was 
prostrate for about 3 of its length, the apy iene portion of the 
-gfostrate part had md out several strong roots,) 1 foot from 
the crown of leaves 16 inches, around the last distinct annu- 
lus 15 inches, at the base of the erect part, the diameter 5}. 
There is no distinction of bark, the great substance of the 
axis being composed of white dense cellular tissue. 
The axis is occupied by pith of enormous dimensions, of 
close white cellular tissue; adjoining this, is a broad zone of . 
fibrous wood of a yellowish brown colour. 'These zones vary 
in number from 2 to 3, and vary likewise in this, that they 
are close together, and are separated by white fibrous tissue. - 
The space between the outer zone which is small, and the 
cuticle is occupied by cellular tissue, white and dense, im i
