Tbis approaches Guatteria sumatrana, Miq. in its leaves : but that 
species has much larger flowers. Bat this is still more allied to Gicatteria 
kypoglauca, Miq,, from which it differs by its much larger fruit. The 
plant named P. hypoleuca by Kurz in his Forest Flora of Burmah is, as 
he himself informed Sir Joseph Hooker in a letter, really P. sumatrana. 
Neither species, however, appears to me to occur either in the Anclamans 
or Burmah. 
3. Polyalthia SUMATRANA, King (not of Kurz.) A tree 30 to 60 
feet high: young branches pale, the older much furrowed : all parts 
glabrous except the flowers. Loaves coriaceous, oblong-lanceolate, acu- 
minate, the base acute; upper surface shining, the lower dull glaucous, 
both pale (when dry) ; main nerves 15 to 20 pnirs, very slender and 
little more prominent than the secondary ; length 4*5 to (5*5 in., breadth 
1-25 to 3*75 in., petiole *25 in. Flowers 1*4 to 1*75 in. long, solitary or 
in fascicles of 2 or 3 from the younger branches below the leaves, or 
axillary ; their pedicels "6 to 9 in. "long, minutely bracteolate near the 
base, glabrous. Sepals very small, hal£-orbicular-ovate. Petals narrow- 
ly linoar-oblong, sub-acute or obtuse, puberulous, pale green to yellowish, 
the outer slightly longer than the inner, 1*35 to 1*75 in. long and *15 to 
*2 in. broad. Ovaries glabrous, sub-cylindric, with a single ovule: stigma 
hairy. Carpels ovoid, tapering to each end, ridged (when dry), pubes- 
cent or glabrous, about 1 in. long and *6 in. in diam. ; their stalks "5 to 
•6* in. long. Guatteria sumatrana, Miq. PI. Ind, Bat. Suppl. 380. Monoon

Tbis is allied to P, hypoleuca t H. f. and Th, ; but has larger leaves, 
much large* llowers, and slightly different carpels. 
4. Polyalthia. andamanica, Kurz Andam. Report (1870) p. 29. 
A shrub : young branches slender, tomentoso. Leaves membranous, 
ovate-lanceolate, acute ; the base broad and rounded, slightly unequal ; 
some of the larger nerves underneath and the midrib on both surfaces 
pubescent near the base, otherwise glabrous and shining ; main nerves 
6 or 7 pairs, distant, spreading and forming bold arches far from the 
margin : reticulations minute, distinct: length 4*5 to 6 in., breadth 2 to 
2*4 in. ; petiole "2 in., pubescent. Flowers axillary or extra-axillary, 
solitary, 2 in. in diam.; the pedicel '4 to "75 in. long, snb-pn Descent, 
minutely bracteolate. Sepals minute ('1 in. long), broadly triangular,
