DESCRIPTION OF ALL SPECIMENS EXAMINED: 
Tree 7 m tall, 18 cm in diameter; bark with 
prominent tubercles or warts; prop roots 1-1.5 
m long, 4 cm in diameter, warty; leaves 1.3- 
1.6 m long, 5-7 cm wide near the base, 3.6- 
5.5 cm wide at the middle, coriaceous, in section 
depressed sinuous M-shaped, sword-shaped, 
tapering from the base to the subulate apex, but 
the actual tip not preserved, the very base 
amplexicaul and unarmed, but at 6-9 cm the 
margins with prickles 1.8-3 mm long, 3-11 mm 
apart, heavy subulate, ascending, brown or 
brown-tipped; the midrib below beginning at 
15-20 cm up with prickles 1.6-2. 2 mm long, 
13-45 mm apart, slender subulate, ascending; 
at the midsection the margin with subulate- 
serrae 1-2 mm long, 4-10 mm apart; those of 
the midrib below similar but 10-32 mm apart; 
near the apex the margins and midrib below 
with subulate-serrulations 0.2-0. 7 mm long, 
2-7 mm apart; peduncle 13 cm long, bracted; 
syncarp solitary, the core 13 cm long, 4.5 cm in 
diameter, cylindric-ellipsoid, obtusely deltoid; 
phalanges 4. 8-5. 6 cm long, 2. 5-4.7 cm wide, 
2.3-4. 1 cm thick, orange-yellow, pyriform or 
cuneate-pyriform, the apex rounded (rarely 
flattish), upper % free and in the free part the 
lateral sutures distinct from half to all its length, 
4- 7-angled, the sides smooth, shining, when 
dried light brown, gently curving or plane; 
apical central sinuses 3-6 mm deep, V-shaped; 
carpels 6-13, the central apices somewhat the 
smaller, pyramidal or slightly oblate pyramidal 
to semiorbicular and most of them with a small 
distal concavity, the tips ascending or on a few 
slightly divergent; stigmas 1-2 mm long, apical, 
oval to orbicular, dark, creased, oblique, centri- 
petal; proximal sinus deep, running p|“% wa y 
to valley bottom; endocarp supramedian, 2-2.2 
cm long, bony, dark brown, the lateral walls 
3-4 mm thick; seeds 12-15 mm long, ellipsoid 
or obliquely so; apical mesocarp in each carpel 
forming a cavern with a few strong longitudinal 
libers and white medullary membranes; basal 
mesocarp fibrous and fleshy.
