S. Andaman : Kurz, Man, King's Collector. 



Allied to P. Jenkinsii, H. f. and T. ; but with much smaller flowers, 

 and leaves with broader bases. 



5. PoLYALTHiA MAGNOLi^FLORA, Maing. MSS. Hook fil. Fl. Br. Ind. 

 I, 64. A tree 30 to 40 feet high ; young branches rusty-tomentose. 

 Leaves thinly coriaceous, oblong to obovate-oblong, obtuse or acuminate, 

 the base rounded or minutely cordate ; upper surface glabi'ous, the 

 nerves and midrib minutely toraeutose ; under surface at first pubescent, 

 ultimately glabrous or glabrescent : main nerves 15 to 20 piirs, rather 

 straight, oblique, pi'omiuent beneath, the transverse veins almost 

 straight, distinct ; length 8 to 12 in., breadth 2'5 to 35 in. ; petiole "25 

 in. stout, tomentose. Flowers large, shortly pedunculate, solitary, axil- 

 lary, 2"5 to 3 in. long; peduncle "3 in. long, tomentose, with 2 large 

 ovate bracts. Sepals coriaceous, short, broadly ovate, acute, spreading, 

 tomentose. Petals coriaceous, white, linear-oblong or oblong- lanceolate, 

 sub-acute, tomentose. Torus conical. Ovaries hirsute. Carpels (un- 

 ripe) stalked, oblong-ovoid, blunt at either end, the apex mucronate, 

 pubescent. Seed with smooth shining testa. 



Malacca : Maingay. Perak ; King's Collector, No. 10039, 

 Evidently a rare species. I have seen only Maingay's imperfect 



specimens from Malacca, and two collected on Ulu Bubong by the late 



Mr. H. H. Kunstler. Collector for the Bot. Garden, Calcutta. Sir J. D. 



Hooker states (F. B. Ind. 1. c.) on Maingay's authority that the flowers 



have the colour and odour of those of a Magnolia. 



6. POLTALTHIA MACRANTHA, King n. sp. A tree 20 to 70 feet high ; 

 young bi'anches rather slender, glabrous. Leaves large, thinly coriace- 

 ous, oblong to elliptic-oblong, acute, slightly narrowed below the middle 

 to the rounded or minutely cordate base ; upper surface shining, 

 glabrous except the depressed slightly puberulous midrib ; lower surface 

 paler when dry, glabrous, very minutely lepidote ; main nerves 20 to 24 

 pairs, spreading, thin but prominent beneath; lengtli 12 to 18 in., 

 breadth 4'5 to 7'5 in., petiole "4 in., stout. Flowers solitary, axillary or 

 slightly supra-axillary, 25 to 45 in. in diam.; pedicels 15 to 2 in. 

 long (longer in fruit) glabrescent, with a sub-orbicular bracteole about 

 the middle ; the buds conical wlien young. Sepals thick, sub-orbicular, 

 spreading, connate by their edges and forming a cup "To in. in diam., 

 puberulous on both surfaces, corrugated outside. Petals much larger 

 than the sepals, white, thick, fleshy, flattish, oblong-elliptic, widest above 

 the middle, blunt, puberulous on both surfaces except at the glabrescent
