Roxburgh says of his 8. moluccana, " Habitat in insulis Molnccanis." His 

 description is extremely short and insufficient, and there does not seem to have been 

 a specimen in his herbarium nor was it figured by him. It is very improbable that 

 the plant he described was identical with the Penang plant, if he received it really 

 from the Molnccas, as the distribution of most species of the section Hexadon is 

 very local, and no specimens, referrable to S. paradoxa, have been discovered, so 

 far, east of the Malay Peninsula. On the other hand, it is possible that Roxburgh 

 meant 8. malaccana instead of " 8. moluccana " and insulis malaccanis for 

 11 ins. moluccanis," as the editors of his Flora Indica put it. There is at least nothing 

 in his description which would contradict the assumption that his brief diagnosis 

 was drawn up from the Penang plant. In view of this uncertainty we have preferred 

 to follow Naudin and to consider Roxburgh's 8. moluccana as a " species dubia " 

 and adopt Naudin' s name for the Penang plant. 



34. Sonerila begoniaefolia, Blume in Flora (1831), 490. An 

 ascending, usually unbranched herb, 2-6 in. high, moderately hairy with 

 the exception of the often glabrous upper side of the leaves ; hairs of 

 the stem, petioles and the inflorescence rufous, flexuous, more ov less 

 spreading, of the leaves confined to the nerves and veins of the under- 

 side, often scanty, very short. Stem rather slender, rooting below. 

 Leaves very dissimilar, the larger of each pair petioled, more or less 

 asymmetrical, obliquely elliptic, subacuminate, unequally cordate at the 

 base with a rounded lobe (2-*3 in. long) on the outer and a much 

 smaller on the inner side, entire or more or less obtusely serrulate, 

 ciliolate, membranous, dark- green above, pale brown (when dry) 

 beneath, 3-4 in. by 17-2 3 in., 6- sub-7-nerved from near the base 

 (with 3-4 nerves in the broader half), with usually very conspicuous 

 subhorizontal transverse veins; petiole '4-l'2 in. long; small leaves 

 ovate to rotundate, acute, cordate, very small, distinctly petioled. 

 Cymes terminal and axillary, peduncled, dense, at length up to *8 in. 

 long, deciduously bracteate ; peduncle slender, up to 1*5 in. long; bracts 

 linear-oblong, ciliolate, up to *1 in. long, deciduous; pedicels -07-1 in. 

 long. Calyx campanulate-oblong, teeth broad, triangular. Petals 

 ovate, acute. Anthers short, oblong, obtuse. Fruit shortly turbinate, 

 •18-22 in. long and wide, muricate-tuberculate, tubercles rather coarse, 

 acute, mostly passing into short fine bristles. Korth. in Verh. Nat.
