mass on a sliort tliick anthophore ; anthers oblong, bluntly apiciilate, 

 filaments varying in lengtli (the inner the longest). Female perianth 

 of 5 unequal pieces : styles 2, rather long, combined at the base. Cap- 

 sule not seen.

Specimens of this plant are rather scanty. They resemble B. megaptera, but 

 are nob caulescent like that species. In the Calcutta Herbarium there is, under 

 the name Diploclinium tuherosum, Miq., a specimen collected by Knrz in Western 

 Java which apparently belongs to this species. There are also two plants 

 from Sumatra collected by Forbes (Herb. Forbes 2333a and 2255) which appear to 

 belong to this. The genus Diploclinium is inseparable from Begonia and the specific 

 name tuherosa is'pre-occupied in the latter by a species described by Lamack from 

 the Moluccas which has a rounded tuberous root. 



17. Begonia Maxwelliana, King n. sp. Rhizome as thick as a 

 swan-quill, bearing many broadly lanceolate scales. Leaves broadly 

 and obliquely ovate to ovate-rotund, more or less acuminate, the edges 

 minutely ciliate-denticulate, the base very oblique, one side of it rounded 

 the other rounded-auriculate, the sinus wide ; both surfaces with a few 

 coarse compressed rusty hairs, most numerous on the nerves near the base ; 

 the lower surface with minute white scales ; main-nerves 7 to 9, radiat- 

 ing from the base, prominent ; length 5 to 6 in. ; breadth 4 to 7 in. ; 

 petioles 4 to 10 in. long, compresed (when dry) like the peduncles 

 and like them rusty-pubescent. Peduncles unequal, those bearing only 

 male flowers often shorter than the petioles ; those bearing female and 

 male, or females only often longer than the petioles ; all ebracteate 

 below the inflorescence, dichotomously branched and few-flowered at the 

 apex ; the bracts short, broad. Male flowers densely clustered ; sepals 

 2, oblong-ovate, blunt, '4 in. long, puberulous outside ; 'petals 2, similar, 

 but much smaller. Stamens numerous, without anthophore ; anthers lin- 

 ear, bluntly apiculate, slightly shorter than the filaments. Female peri- 

 anth of 5 unequal pieces diminishing in size inwards ; styles 2, short, much 

 lobulate. Capsule 2-celled, 1*4 in. broad (to the ends of the wings) and 

 •6 in from base to apex ; the 2 lateral wings sub-quadrate, obtuse ; the 

 posterior oblong, blunt, more than three times as long as the lateral.

The flowers of this are white tinged with pink and the leaves green, the nerves 

 beneath being red. This resembles B. megapteroidea, King, but the flowers are 

 smaller, and the leaves and inflorescence are not glabrous as in that species. 



18. Begonia pr^eclara, King n. sp. Rhizome creeping, very scaly. 

 Leaves obliquely ovate, acuminate, the base rounded on one side of the
