TO LOWER SIAM. 187 



spreading as it does in well grown plants of typical P. 

 javana The structure of the ilowers and the form of the 

 achene is identical. P. acaulis, is a native of Penang 

 and has long been in cultivation in Singapore Botanic 

 Gardens, where it has spread on the rock tables like 

 the other species. It seems, however to maintain always 

 its dwarf form, I would propose to call it therefore. P. 

 javanica var. acaulis. 



A more distinct variety is the following which was 

 sent some years ago to the Botanic Gardens, Singapore 

 from Penang and obtained originally on the East Coast of 

 Siam somewhere I believe in the region of Trang. 



Pcllionia javanica var. pulclicvrima, Stem creeping, Leaves 

 oblique lanceolate, acuminate, base , oblique peltate, mar- 

 gin entire, bullate, dark green mottled, lighter beneath 

 pale, nerves elevated, pubescent, 6 inches long, 1\ inches 

 wide, petiole 1-li inch long, stipules lanceolate, caudate, 

 i inch long. Peduncle 3 inches long, stout, succulent red, 

 branches four, dichotomous, 1-li inch long, densely 

 lloriferous. Male flowers rV inch across. Perianth lobes 

 4, oblong, pale green, tinted pink. Stamens 4, anthers 

 short, pale "pink, filaments thick, pale green. Females 

 in a sessile head, i inch through, perianth green on 

 pedicels as long as the perianth, lobes 4, acute, pubescent. 

 Achene flattened, obovoid, shortly beaked, violet with a 

 white elevated margin. 



East Lower Siam, exact locality doubtful. 



This has been for some time cultivated in Singapore 

 being introduced by Mr. Curtis. 



It is certainly closely allied to P. javanica, Wedd. 

 the Penang plant, but the leaves are more fleshy, bullate, 

 and of a different color, the nerves on the underside are 

 more hairy. The inflorescences male, female and mixed 

 are similar to those of P. javanica, and the flowers are 

 quite similar. The achenes, however are not distinctly
