DIAGNOSIS of holotype: Shrub, its main 
stem 5-7 m long, 3-4 cm in diameter, its verti- 
cal base usually decaying and vanishing, the 
middle section more or less horizontal, sup- 
ported by numerous horizontal or ascending 
prop roots 2-3 m long, 2 cm in diameter, green 
to gray, muricate; leaves 28-42 cm long, 4- 
7 mm wide, above green, below pale green with 
dark-green veins, at midsection with 8-9 par- 
allel secondary veins in each half, tertiary veins 
none, over the midrib with a broad, shallow 
furrow, then the sides gently down-curved but 
not pleated, blade ligulate but the outer y s 
gradually long tapering into a 10-15 cm flat- 
tened, subulate apex, this 10 cm down 2-3 mm 
wide, base amplexicaul, unarmed, dark shiny 
green even where covered, prickles all white, 
translucent, at base beginning at 6-10 cm up 
the margins with prickles, the lowest ones 
0.8-1. 2 mm long, 1.5-3 mm apart, oblique 
deltoid, slightly ascending, then the next series 
1.3-2 mm long, 2-6 mm apart, arcuate subu- 
late from a deltoid base, ascending; beginning 
at 4-5 cm up the midrib below with prickles 
0. 5-0.6 mm long, 2-5 mm apart, arcuate subu- 
late, ascending; at midsection the margins and 
midrib below with prickles 0.6-1 mm long, 
2.5-4 mm apart, arcuate subulate, ascending; 
on the subulate apex the margins and midrib 
below with subulate-serrulations 0. 3-0.6 mm 
long, 1.5-3 mm apart; infructescence terminal, 
bearing one syncarp; peduncle 2-2.5 cm long, 
3- 4 mm in diameter, straight, ascending, with 
several apical bracts closely subtending the 
syncarp, the two outer ones with the base 10— 
12 mm long, 4—10 mm wide, expanded, yellow- 
ish, lanceolate, navicular, bearing a foliaceous 
tip 3-12 cm long, 2-2.5 mm wide at base, 
subulate; syncarp 3.5-4 cm in diameter, globose, 
bearing (5)-6— (7) drupes, green (perhaps 
always so) ; drapes 16-21 mm long, 16-20 mm 
in diameter, 1 -celled, subglobose, green, 3-5- 
angled, the lower section cuneate with flattened 
sides, slightly more than upper y 2 free, smooth, 
shining; stigma apical, horizontal, 2-2.5 mm 
in diameter, orbicular-cordate, elevated, pale 
brown, papillose; endocarp supramedian, 13- 
14 mm long, bony, pale brown, broad ovoid, 
with median lateral flange, lateral walls 5-6 mm 
thick, within light chestnut-brown, smooth, 
shining; seed 5 mm long, 3 mm in diameter, 
oblique ellipsoid ; apical mesocarp of moist 
pith ; basal mesocarp fleshy and fibrous. 
juvenile PLANT (St. John 26,534) : Stem 
60 cm tall, 1.5 cm in diameter; leaves 45-55 
cm long, 8-10 mm wide, at midsection with 
10-11 secondary parallel veins in each half; 
near the base the principal marginal spines 
4- 4.5 mm long, 9-24 mm apart; midrib below 
unarmed to beyond the middle. 
holotypus: Malagasy Republika, Amani- 
nomby, 20 km N.E. of Majunga, 2 km inland, 
low scrub forest of Terminalia sp. and Side- 
roxylon sp., on dry sand plain, 10 m alt, Aug. 
8, 1961, H. St. John 26,533 (bish). 
discussion: P. subglohosus is a member of 
the section Microstigma, as is its closest rela- 
tive, P. oligocarpus Martel h, of the nearby 
plateau d’Antanimena, a species with the syn- 
carp bearing 9 drupes; drupes 13-15 mm long, 
ovoid, the upper % free; endocarp in longi- 
tudinal section irregularly ovate; and the leaves 
40-70 cm long. P. subglohosus has the syncarp 
with usually 6 drupes; drupes 16-21 mm long, 
subglobose, upper y 2 free; endocarp in longitu- 
dinal section irregularly cruciform ; and the 
leaves 28-42 cm long. 
The new epithet is the Latin adjective, sub- 
globosus, almost spherical, and is given in allu- 
sion to the shape of the drupes.
