Rodriguez, abundant over the island, Barkly / Horne! Balfour! Endemic. A 
very variable plant, assuming marked forms in the individual drupes and shape of 
the heads. According to these variations it is known as Vacoa cale rouge , Vacoa cale 
blanc , Vacoa poteau, Vacoa parasol, Vacoa Sac, and Vacoa mule. F. ornatus, Hort. of 
which a young flowerless plant is figured by Andre in the Illustration Horticole, vol. 
xix. t. 97. and in Journ. Hort. Soc. Lond. Misc. I. 1866, is probably the same species. 
9. P. tenuifolius, Balf. fil. A small tree, about 15 feet high, 
growing usually in clumps, with a light brown smooth stem about 3 in. 
in diameter, branching freely at an acute angle, the thick erect branches 
ending abruptly in tufts of reflexed drooping leaves. Leaves coria- 
ceous, dilated and widely amplexicaul at the base, narrowed to a long 
point, 8-24 in. long, in. broad, dark green, often very glaucous at 
the base ; margins thickened, slightly tinged with red, armed throughout 
or except at the middle with sharp red spines; blade not reduplicate; mid- 
rib red, spiny above the middle ; lateral veinlets distinct beneath. Female 
heads subglobose, 3-5 in. in diameter, containing 20-40 drupes, pendu- 
lous from a curved peduncle 5-11 in. long. Drupes 2-5-celled, shortly 
pyriform, 1| in. long, lf-lj; in. broad, 1^-1 \ in. deep, free in the 
upper third or quarter, not compressed ; connate portion 5-6-angled, 
obversely pyramidal; apex dome-shaped, faintly 5-6 angled, with a 
somewhat flattened summit with a distinctly-bordered areole in the 
centre containing the flat sessile reniform stigmas, which are i in. 
broad ; endocarp smooth, more or less rounded, flattened at the top, 
with a prominence running to each stigma and sending out few fibres to 
pierce the mesocarp, which is thick round the endocarp. Seed -I in. 
long.

10. P. Iceryi, Horne , MSS. A tree 20-30 feet high, with an un- 
branched stem terminating in an erect tuft of leaves. Leaves 2-6 feet 
long, 3-6 in. broad, narrowed suddenly to the point, bright green above, 
glaucous beneath ; the margins armed except at the middle with closely- 
set white spines; blade reduplicate on each side of the midrib, with a 
tendency to split at the top. Female heads ovoid, 3-4 in. long, con- 
taining about 40 drupes, cernuous ; peduncle arising from the main 
trunk, under a foot long, with numerous small leafy bracts. Drupes 
2-5-rarely 1-celled, 1-li in. long, f in. broad, free in the upper third, 
slightly compressed, regularly 5-6-angular ; apex dome-shaped, with a 
depressed areole in the centre, enclosing the crowded flat sessile 
prominent, reniform stigmas, which are ± in. broad ; endocarp medial, 
sending out few fibres into the mesocarp, which is thin round the 
endocarp. Seed ± in. long.
