ovaries. Stamens many, linear-oblong or cuneate, truncate ; anther-cells 

 dorsal, remote (small and ovoid in 0. glauca). Ovaries oblong, strigose ; 

 style oblong or clavate, recurved ; ovules 1-2, sub-basal, ascending. 

 Ripe carpels 1-seeded, stalked. — Distrib. About 28 species, Asiatic and 

 African. 



A genus of which the flowers have some resemblance to those of 

 Goniothalamus : but in this the inner petals are not contracted into a 

 claw as in Goniothalamus and the calyx in this is smaller and not 

 persistent. 

 Outer petals flat ... ... ... 1. 0. affinis. 



Outer petals concave. 



Pedicels slender, much longer than the flowers 2. O.filipes. 

 Pedicels shorter than the flowers. 



Leaves oblong-elliptic, more or less obovate, 



blunt ... ... ... 3. 0. calycina. 



Leaves oblong-elliptic to oblong-lanceolate 

 or elliptic-lanceolate, not obovate, acute, 

 or acuminate. 



Outer petals expanded and concave in 

 the lower third ; the inner only one 

 fourth as long as the outer, very 

 acuminate ... ... ... 4. 0. biglandulosa. 



Outer petals narrowly linear-lanceo- 

 late, slightly expanded and concave 

 at the veiw base ... ... 5. 0. glauca. 



1. Oxymitra affix is, Hook. fil. and Thorns. Fl. Br. Ind. I, 70. A 

 spreading shrub or climber : young branches at first densely rusty to- 

 mentose, afterwards dark-coloured and glabrous. Leaves membranous, 

 elliptic to oblong-elliptic, sometimes slightly obovate, acute or very short- 

 ly acuminate, rarely obtuse, the base rounded or slightly narrowed ; 

 upper surface shining, minutely scaly, glabrous except the pubescent 

 midrib ; under surface slightly glaucous, pubescent especially on the 

 midrib and nerves ; main nerves 8 to 14 pairs, spreading, ascending, 

 rather prominent on the lower surface ; length 35 to 10 in., breadth 

 1-25 to 4 - 5 in. ; petiole "3 in., tomentose. Flozvers solitary, extra-axillary ; 

 pedicels '25 to "4 in. Sepals slightly connate at the base, spreading, 

 broadly ovate or orbicular-orate, sub-acute, 3- to 7-nerved, adpressed- 

 pnbescent, - 5 in. long and slightly narrower than the base of the petals, 

 persistent in the fruit. Petals flat, very unequal ; the outer thinly 

 coriaceous, oblong-lanceolate, sub-acute, the midrib thick and with 

 several strong sub-parallel nerves, adpressed-pubescent on both surfaces, 

 15 to 175 in. long and '4 to "6 in. broad; inner petals thickly coria-
