Java, Sumatra. 
This species has usually been placed in Sect. Lirmocarpus as believed to 
have the acorn completely attached to the cupule, but as after cutting through 
a good, quite ripe specimen I find this not to be the case, I have followed Oersted 
in transferring it to Sect. CycnoBatANnus. King considers the Peninsular 
‘material to belong to Blume’s var. convexa, but I cannot agree in this. 
Scortechini’s specimens agree well with both Blumes’ and Oudemans’ figures, and 
the rest of the material differs only in having the fruit (much more mature) 
very broad and obconic instead of cylindrical. The thickness and hardness 
of the pericarp is most remarkable. 
26. PASANIA LAMPADARIA, Gamble in Kew Bull. 177 (1914). A 
small tree ; branchlets very stout with smooth dark-grey or nearly 
black bark, rough with dark rounded lenticels. Leaves very coria- 
ceous ; lanceolate, acuminate at apex with an oblique obtuse acumen, 
attenuate at base and more or less decurrent on the petiole ; upper 
surface smooth, shining, lower whitish when fresh with a minute 
felted pubescence, grey when dry ; margins entire, recurved ; 20—25 
cm. long, 6—10 em. broad ; midrib very thick and prominent; main 
nerves 12—14 pairs, at first nearly straight, curving to vanish along 
the margin; transverse nervules many, subparallel, slightly arched ; 
reticulation obscure ; petiole very stout, wrinkled, 1—1:5 em. long, 
bordered partly by the decurrent margins of the blade. Flowers not 
known. ruts (immature) sessile in stout spikes about 10 cm. long, 
usually 3 together, occasionally more, sometimes (the lower ones) 
single or in pairs; cupules enclosing about three-fourths of the half 
mature acorn ; lamellae to each acorn about 5, minutely denticulate ; 
acorns white-sericeous ; umbo prominent, conical.
