of its habitat has been noted, whether in India, Malaya, or the 

 Philippines, the records are very uniform ; it is stated to occur in ex- 

 posed sunny waste places ; in waste ground near villages ; at or near 

 cleared camping grounds ; near sites of abandoned dwellings ; or in 

 native gardens. The form that occurs in native gardens in India and 

 Ceylon is also met with in gardens in Java ; the same form has also 

 been collected in Tonkin. So far, however, it has not been reported 

 from Sumatra, the Malay Peninsula, or Borneo. 



Though the name Patchapat — Patchouli leaf— is probably applied 

 indifferently in Indian bazaars to any leaf that has the characteristic 

 Patchouli odour, there is no doubt that in Indian gardens in which 

 the plant is grown the vernacular names Patchouli and Patch a are 

 applied exclusively to the scented cultivated state of P. Heyneauus, 

 with leaves rather thicker than those of the wild plant. The name 

 P. Patchouli, which was first applied to P. Heyneanus by Dalzell and 

 Gibson [Flor. Bomb. Addend, p. 66, in 1861, and was subsequently 

 adopted in the Flora of British India, vol. iv., p. 633, is on this account 

 very appropriate. Unfortunately, however, the name P. Patchouli 

 connot be employed for the plant to which the vernacular term 

 Patchouli is alone applied ; first, because the Indian plant known to the 

 natives as Patchouli or Patcha had already been named P. Heyneanus 

 in 1828 ; again, because the name P. Patchouly , which was used by 

 Pelletier for the first time in 1844, was not applied by him to the plant 

 known in the Indian vernaculars as Patchouli, but was given to the 

 Patchouli of commerce, which is not an Indian plant at all. 



This Patchouli of commerce, as already explained, stands in the 

 Flora of British India as Pogostemon Patchouli, var. suavis. Now, 

 however, that fuller material is available, it is found that the two 

 Pogostemons which possess the Patchouli odour, viz. : — P. Heyneanus, 

 Benth., or P. Patchouli, Dalz. and Gibs., the cultivated plant known in 

 Indian native gardens as Patchouli, and P. Patchouli, var. suavis, the 

 Patchouli of commerce, are even more distinct than they were thought 

 to be when the account of the genus Pogostemon was drawn up for the 

 Flora of British India. They admit of being treated as specifically 

 separable. In P. Heyneanus the leaves are much thinner and are 

 sparingly puberulous, are almost smooth ; the flowers, which are freely 

 produced in all the countries in which the plant has been found, are 

 in small whorls less than half an inch across, separated by distinct 

 interspaces throughout the spikes in which they are arranged ; the 

 corolla is glabrous outside except for a few hairs on the margin of the 

 lower lip. In the Patchouli plant of commerce the leaves are thicker 

 and firmer, and are densely pubescent, especially beneath ; the flowers, 

 which are freely produced only in the Philippines but which have 

 occasionally been met with also in European cultivated specimens, are 

 in larger whorls, three-quarters of an inch across, which are con- 

 tiguous throughout the spikes in which they are arranged, or have 

 only the lowest whorl separated by an interspace from the rest of the 

 spike ; the corolla is uniformly pubescent outside. 



The Patchouli plant of commerce has been differently named by 

 different authors. Tenore, who flowered it in Italy in 1847, described
