ter, bearing seven more or less perfect, alternate patent 
branches, each about 4 inches long. These branches are 
much more slender than the main stem, and taper remark- 
ably at their insertion; they are naked in their lower part, 
but above are distantly pinnate; the pinne are alternate, 
either simple or pinnulated, and regularly and closely whorled 
with very slender straight simple jointed ramuli, 8-10 times 
longer than the distances between the whorls, and having 
cylindrical joints 5-8 times longer than their diameter. 
Colour rosy red. Substance not very tender, the stem only 
imperfectly adhering to paper. Externally the stem and 
branches appear inarticulate, but internally they are many 
tubed.

George Town, V. D. L., R. Gunn, Esq., n. 1303 in part.— 
Fronds 4 inches, or probably much more in length, 3 of a 
line in diameter at the base, gradually smaller upwards, 
irregularly divided many times in a pinnate manner, the 
divisions patent with rounded axils. Branches rather flexu- 
ous, opake, and not distinctly jointed, but divided at inter- 
vals of 4-5 diameters into portions resembling joints nar- 
~ Towed at their base and swelling upwards, almost pyriform ; 
from the swollen part of which spring lesser branches or 
Pinnules, also inarticulate, but furnished with jointed single 
tubed ramuli, which are not of much less diameter than the 
Pinnules, These ultimate ramuli are contracted at the basal 
"oint, and gradually taper to an acute apex ; they are simple 
àt the lower part of the pinnule, erecto-patent and rather 
distant; those in the upper part of the pinnule are alter- 
nately divided or pinnulated:—thé joints in all about 2-3
