THE LABIATES OF THE MALAY PENINSULA. 107 



(2). Herbs growing in the jungles and obviously in- 

 digenous the Gomphostemmas, and I believe Pogostemon 

 Ileyneanus, Benth. the Indian patchouli. 



The Pogostemon is not so far as I am aware cultivated 

 here, but it is possible that it is. I have met with it on 

 stream banks in forests, at Eawang in Selangor (No. 7603 of 

 my collection) and at Taka Tahan on the Tahan River (No. 

 2031) also in Sarawak at Lundu (No. 1238) and it is in 

 Haviland's collection from Penkulu Ampat in Sarawak. In 

 the Tahan River locality it was growing near Colocasia anti- 

 quorum at an old Sakai camping ground, and was probably 

 carried there by the Sakais, but there was nothing to suggest 

 it had been introduced in the other localities. It is known 

 to the Malays as Rumput Ruku, Poko Nijao, Nilam Bukit 

 and Chilam Bukit. It is used as a poultice in cases of head- 

 ache, rheumatism and boils, and in the form of a decoction is 

 drunk for dropsy. The flowers the colour of which is not 

 given in the Materials are pale violet. 



P. Cablin, Benth. the commonly cultivated patchouli is 

 described fully in the Materials. Its native home is quite 

 unknown. 



Dysophylla auricularia, Bl. is undoubtedly wild here, I 

 think. It grows in swampy open ground, edges of rivers, etc. 



Scutellaria discolor, Benth. was once collected by Scor- 

 techini in Perak and is probably wild. I have never seen it. 



(3). The third set of indigenous Labiates are all from 

 the limestone rocks of Ipoh and near by. They are Plectran- 

 thus Kunstleri, Prain., Paraphlomis rugosa, Pram, and 

 Cymaria dicliotoma, Benth., Acrymia ajugiflora, Prain. The 

 occurrence of four species of this order out of so small a 

 number of indigenous species on such a limited area as this 

 range of limestone hills is very remarkable. 



Tims this large order is represented in the Malay pe- 

 ninsula by only 15 species which can be considered to be truly 

 indigenous.
