This approaches Guatteria sumatrana, Miq. in its leaves : but that 

 species has much lai-ger flowei-s. But this is still more allied to Guatteria 

 hypoglauca, Miq., from which it differs by its much larger fruit. The 

 plant named P. hyjwleuca 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 Andamans 

 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. Leaves coriaceous, oblong-lanceolate, acu- 

 minate, the base acute ; upper surface shining, the lower dull glaucous, 

 both pale (when dry) ; main nerves 15 to 20 pairs, very slender and 

 little more prominent than the secondary ; length 4-5 to 6*5 in., breadth 

 1-25 to 1-75 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, half-orbicular-ovate. Petals narrow- 

 ly linear-oblong, sub-acute or obtuse, puberulous, pale green to yellowish, 

 the outer slightly longer than the inner, 1*35 to I '75 in. long and '15 to 

 •2 in. broad. Ooaries 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. loner. Guatteria suviatrana, Miq. Fl. Ind. Bat. Suppl. 380. Monoon

Perak ; at elevations up to 2,500 feet, common. Distrib. : Sumatra, 

 Korthals, Beccari P. S., No. 613. Borneo, Korthals. 



This is allied to P. hypoleuca, H. f. and Th. ; but has larger leaves, 

 much larger flowers, and slightly different carpels. 



4. PoLYALTHiA ANDAMANiCA, Kurz Andam. Report (1870) p. 29. 

 A shrub : young branches slender, tomentose. 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 45 to 6 in., breadth 2 to 

 24 in. ; petiole "2 in., pubescent. Flowers axillary or extra-axillary, 

 solitary, 2 in. in diam.; the pedicel 4 to -75 in. long, sulj-pnbescent, 

 minutely bracteolate. SepaZs minute ("l in. long), broadly triangular, 

 pubescent. Petals thinly coriaceous, sub-equal, oblong, blunt, I iu. long. 

 Bipe carpels 6 to 8, oblong, smooth, glabrous, slightly apiculate, '5 or 6 in.
