Knrz describes the calyx-lobes and petals as 6 each, and in thnt he is quite 

 wrong; for dissection of Griffith's siDecimen (which is the type of the species) shows 

 10 of each. Although the structure of the flowers is the same in the gatherings 

 of this plant from Burma, Kedah and Trang, there is considerable difference as to 

 the amount of hair on the leaves and also as to their edges. The Burmese specimens 

 are rather obscurely crenate except when very young ; the Kedah plant lias its adult 

 leaves boldly crenate and minutely pubescent on the lower surface and glabrescent 

 on the upper (except the midrib and main nerves) ; while the Trang specimens are 

 glabrescent on both surfaces, with the exception of the nerves and midrib. The 

 flowers of the Trang plant are moreover slightly larger than those either from 

 Kedah or Tenasserim. 



5. HoMALiUM FRUTESCENS, King. A tree 20-30 feet high ; young 

 branches slender, pale when dry, glabrous, striate. Leaves thinly 

 coriaceous, elliptic-oblong to elliptic, shortly acuminate, tapering slightly 

 to the base ; main nerves 7 or 8 pairs, curving upwards, prominent beneath ; 

 both surfaces glabrous, minutely reticulate, the lower pale-brown and 

 the upper olivaceous when dry; length 3-5 in., breadth 1-75-2-25 

 (rarely 2*75 in.), petiole *! in. Baceiues axillary, sometimes with 2 or 3 

 branches, about as long as the leaves or sometimes longer, the rachis 

 puberulous ; the flowers numerous but not crowded, in pairs or solitary, 

 about '25 in. long, and *! in. or '15 diam. at the mouth ; the pedicel 

 under *1 in. in length. Calyx narrowly cylindric-conic, boldly ridged ; 

 teeth 6, lanceolate, acute, erect. Petals larger than the petals, oblong- 

 lanceolate, pubescent on both surfaces but especially on the upper. 

 Stamens 4 opposite each petal and slightly exceeding it in length, 

 glabrous. Ovary hairy, elongate; styles 5, as long as the stamens, 

 cylindric, erect. Fruit unknown. Blackwellia longijiora, Miq. Flor,
