40 to 50 feet high \ young branches Blender, almost blaclc when dry 
when very young covered by deciduous furf uraceous rufous stellate 
hairs. Leaves thinly coriaceous, very inequilateral, oblong to ovate or 
lanceolato-oblong, entire, acuminate ; the base broad, unequally cordate, 
one side auriculate or sab-auriculate ; upper surface very dark when 
dry, glabrous, shining; the lower densely but minutely tawny or rufous- 
tomeutose with many deciduous ctnuamoneous stellate hairs on the 
surface ; main nerves 5 to 7 pairs, prominent beneath ; length 3 to 
5-5 in., breadth 1*35 to 2 in. ; petiole *15 in. ; stipules subulate-lanceo- 
late. Flowers 2 in. long, solitary, or in 2-3- flowered cymes, axillary, 
or (by the suppression of the leaves) in terminal racemes : pedicels 
*6 in. long, bracteate, cylindric in bud. Sepals coriaceous, narrowly 
linear, acute, Bcurfy, stellate-pubescent externally as are the pedicels 
and bracteoles, pubescent internally. Petals membranous, obliquely 
oblong-oblanceolato or sub-spathulate, shorter than the sepals, glabree- 
cent. Staminal tube and gynophore about "5 in. long, the free part of 
the filaments rather longer; fertile anthers about 10; staminodes 5, 
scaly- pubescent above. Ovary ovoid, villous, 5-celled. Style shorter 
than the staminal tube, glabrous: stigma narrowly ovoid. Capsule 
woody, oblong, 5-angled, sub-acute, gradually and slightly narrowed at 
the base, glabrous when ripe ; 3 to 4 in. long and 1'5 in in rliam. Seeds

A very common tree in Perak. Korthal's Bornean species P. fuscuub 
appears to me to be nothing more than a very cinnaraoneous-tomentose 
form of this. And the Peninsular- Indian P. rubiginosam, Heyne, 
(Mast, in Hook, fil. Fl. Br. lud. i. 368) cauuot be very different. I 
should be induced to reduce both to the oldest described species which 
is this. Of the absolute identity of Kurz's P. cinnamoneum with this 
1 have no doubt whatever. 
3. P. Jackianum, Wall. Cat. 1164. A tree: the small branches 
slender, rather dark, when young covered by a layer of white 
minute tomentum with many rufous stellate hairs on its surface. 
Leaves sub-coriaceous oblong or elliptic-oblong, slightly inequilateral, 
entire, or sinuate towards the rather abruptly acuminate apex ; the baso 
sub-acnte, or truncate and minutely cordate or cmarginatc, never 
auriclod ; upper surface pale brown when dry, trlabrous except the 
puberulouB midrib and nerves; under surface pale brown or buff, with
