the holotype of P. dauphinensis, Perrier de la 
Bathie 11,888. This consists of a dried fruit 
rhachis; a piece of a leaf 20 cm long, 11 cm 
wide, and one half of it continuing 55 cm 
more; a single syncarp 18 cm long, 7 cm in 
diameter, cylindric but one side flat, complete 
except that about 9 phalanges have been re- 
moved. The phalanges are nearly all 24-26 mm 
long, only one near basal one on the narrow 
angular side is 3 cm long. Thus, it is clear that 
there are no significant differences between this 
holotypic collection from Bas Matitana and the 
writer’s from Fort-Dauphin, here illustrated. 
The specimen here described was in a partly 
sheltered habitat, in a dune hollow, 75 m 
back from the beach. The others on dune crests 
or nearer the beach were wind battered and 
the syncarps were smaller. They were as small 
as 12 cm long, and 5 cm in diameter, but they 
had the same elongate oblong profile. 
The inhabitants regularly gather the leaves, 
especially the larger ones borne by young plants, 
for the making of mats.

diagnosis OF holotype: Tree 15 m tall, 
25 cm in diameter; trunk erect, unbranched 
almost to the top, the few branches 0.5-1 m 
long, 15 cm in diameter, strictly ascending; 
bark brown, with short conic spines ; prop roots 
few, 20 cm long, 1.5 cm in diameter, light 
brown, spiny; leaves 3.2-3.25 m long, 15-16 cm 
wide, rigid, thick coriaceous, stiffly erect, but 
the outer ones % breaking and pendent, olive- 
green above, paler and somewhat glaucous be- 
low, broadly V-furrowed above the midrib, 
and beyond the middle with 2 lateral pleats, 
the veins rather obscure but at midsection with 
83 parallel secondary veins in each half, blade 
ligulate, gradually tapering in outer third to 
a stout, trigonous subulate apex, this about 
10 cm down 5 mm wide, the base amplexicaul, 
unarmed, white, with membranous, entire 
lateral flanges 38 cm long, 2 cm wide; at base 
beginning at 38 cm the margins with prickles 
2-2.5 mm long, 3-6 mm apart, subulate, diverg- 
ing, then the upper ones ascending; the midrib 
below unarmed for 90 cm; at midsection the 
margins with prickles 1.5-2. 2 mm long, 
5-11 mm apart, arcuate subulate, closely as- 
cending, white, with small brown tips ; the 
nearby midrib below with serrations 0.6-1 mm 
long, 3-7 mm apart, brown tipped; on the 
subulate apex the margins and midrib below 
with serrulations 0. 2-0.9 mm long, 1-2.5 mm 
apart; infructescence terminal, erect, spicate, 
bearing 10 syncarps attached in three rows; 
peduncle 53 cm long, 6 cm in diameter at apex, 
clavate, 3-sided, subtended by two basal, leafy 
bracts 1.7 m long, 8.5 cm wide; rhachis 23 cm 
long; syncarps seen only as remnants; phalanges 
2.6-3. 1 cm long, 1.5-2. 2 cm wide, 1.4-1. 9 cm
