16 NEW OK RARE MALAYAN PLANTS. 



Lankawi: Kwah (Curtis), also occurs at Bang- 

 taphan, Siam (Dr. Keith). 



This lias not previously been recorded for the Penin- 

 sula, but I think I am correct in referring the Lankawi 

 plant to Loureiro's species. 



POLYGALACEAE. 



Polygala cardiocarpa, Kurz. Journ. Roy As. Soc. Beng. 1812 

 * p. 291. 



Slender herb branched above glabrous 6 or more 

 inches tall. Leaves alternate thin ovate obtuse 1-2 inches 

 long I inch wide narrowed into the petiole which is J 

 inch long. Spike- slender 2 inches long, base nude, flow- 

 ers numerous very small yellow -^ inch long. Sepals 4 

 ovate rounded, outer ones larger. Petals oblong ovate. 

 Keel not crested, broad ovate with a prolonged tip. Sta- 

 mens 8. Capsule, sepals deciduous heart-shaped retire, 

 wings strongly ribbed, seed elliptic black pustulate with 

 a small black caruncle. 



Limestone rocks. Selangor : Gua Batu (Kidlev 

 8243); Lankawi: small islands (Curtis 3686), Pulaii 

 Sirih (Curtis 2581) ; Siam: Kasum (Curtis 3250). 



I have little doubt that this little herb is the plant- 

 described by Kurz. under the above name, though his 

 description is rather short. The original plant came 

 from Tenasserim, and this is another instance of this 

 Tenasserim limestone flora descending as far south as 

 the Kwala Lumpur Caves. On the top of the limestone 

 rocks of this spot I met with this little milkwort.

Hypericum japonieum, Thunb. Fl. Jap. 295 t. 31. Hook. ill. 

 Fl. Brit. Ind. I. 256.

 inches tall, with slender branched stems. Leaves ovate 

 sessile opposite glabrous about J inch long blunt.
