FLORA OF EASTERN TROPICAL AFRICA. 433 
spike, and bear a long (nearly 2} lines) linear anther, the con- 
nective of which is prolonged into a short pointed sometimes 
recurving tip. The obconical separate drupes are 14-11 inch 
long, 7-1 inch broad above, the upper third or quarter free, 
smooth, and shortly rounded, with more or less indication of the 
angles, 5-6 in number, exhibited on the lower compressed fibrous 
portion. The flattened, generally oval stigmatic scars, varying 
from 1-5 in number, mostly 4, surround or are seated in a 
central depressed area. The mesocarp is coarsely fibrous and 
spongy, and passes rapidly into the hard woody endocarp, which 
surrounds the clavately oblong seed-chambers, and sends conical 
processes into the thicker spongy upper portion of the mesocarp. 
Approaches the Madagascar species Pandanus utilis, Bory, 
in fruit characters, but is separated by the spicate, not umbellate 
arrangement of the stamens, in which it approaches P. fragrans, 
Brongn., from New Caledonia, as figured in Ann. Sci. Nat. sér. 6, 
i.t. 15,and reproduced without acknowledgment by Solms Laubach 
in his review of the family in Engler and Prantl’s ‘ Pflanzenfami- 
lien’ [II. Theil, 1 Abth. fig. 147 (p. 188)]. The upper part of 
the fruit is also shorter and the leaf-spines are rather larger and 
not reddened. 
The spicate arrangement of the stamens separates our plant 
from all the known African, Malagasy, and Mascarene species.
