Luzox, Province of Pampanga, Mount Arayat (5025 Merrill) February, 1906, 

 det. Rolfe as P. patchouli Pellet.: Province of Rizal, Montalban (2442 Ahern's 

 collector) January, 1905. In forests and thickets, perfectly wild, not cultivated. 



The only record of tliis plant as a Philippine species that I have seen is 

 F.-Villar's, who states that he saw living specimens in Luzon, this record, 

 like so many of F.-Villar's and Naves', being subject to doubt, and accordingly 

 it has been thought best again to record the species as a Philippine one, 

 with citation of specimens. I have followed Hooker /., in considering Pogos- 

 temon heynianus Benth., identical with P. patchouli Pellet., but the former name 

 being the earlier is retained. In consideration of the fact that Hooker f. 

 states "perhaps only a var. of P. parviflorus", it seems probable that the 

 plant recorded from Luzon by F.-Villar. 1. c, as Pogostemon parviflorus Benth., 

 was only a form of P. heynianus. 1 have not seen the species cultivated in 

 the Philippines and the specimens collected on ]Mount Arayat were growing 

 on steep forested slopes at an altitude of about 400 m., remote from any 

 dwelling or settled region, while Ahern's collector informs me that the Mon- 

 talban specimens were from o]ien forests.

Luzon, Manila (14 Merrill) April, 1902, in waste places; Province of Bataan, 

 Lamao River (B. S. 1612 Foxworthy) October, 1906. 



A native of tropical Africa, now widely distributed in the tropics of both 

 hemispheres. 



The species has apparently been distributed by cultivation as an ornaniciital 

 plant, and undoubtedly was so introduced into the Philippines, although I have 

 not seen specimens in cultivation in the Archipelago, where it is perfectly si)onta- 

 neous, although not conunon. It has not previously been reported from the 

 I'hilippines.
