Plectranthus?[ LablatcB. 37 1 



short oval obtuse teeth ; cor.-tube short, lips nearly equal ; 

 stam. exserted, achenes white, smooth and shining. 



Forests of the montane zone, 4000-7000 ft.; common. Fl. February, 

 Sept., &c.; pink. 

 Endemic (.'}. 

 Variable in form and pubescence of leaves. Dries blackish. 



2. P. Walkeri, Am. Pug. 36 (1836). 



Benth. in DC. Prod. xii. 58. P. Jtigrescens, Thvv. Enum. 237 (part). 

 C. P. 90. 



Fl. B. Ind. iv. 617. 



Stems bluntly quadrangular, slightly branched, pubescent, 

 1. numerous, 2-3 in., lanceolate or linear-lanceolate, much 

 tapering to base, subacute, upper part very coarsely dentate- 

 serrate, nearly glabrous or often pubescent on the veins, 

 petioles |- 1 1 in. ; fl. as in P. nigrescens. 



Sides of streams in forests of montane zone, 4000-7000 ft.; rather 

 common. Fl. Feb.; pink. 



Also in S. India. 



I follow Fl. B. Ind. in keeping this distinct from P. nigrescens ; I 

 should prefer to make it a variety. Thwaites combined them. Also dries 

 blackish.

This is made a variety of P. subincisus, Benth., of S. India in 

 Fl. B. Ind. 



P. subincisus., Benth., itself is recorded from Ceylon in DC. Prod. xii. 

 66 on the authority of Macrae. There is also an unlocalised poor 

 specimen (C. P. 2890) in Herb. Perad. alluded to in Thw. Enum. 237. It 

 has the leaf cordate at base. 



P. 2ey/a?tzcus, Benth. (originally described from a specimen sent from 

 Ceylon by Macrae), is the 'Iri-weriya' of the Singhalese, and grown in
