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, how T ever, 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 Patcha are 
applied exclusively to the scented cultivated state of P. Heyneanus, 
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 Pogostevwn Patchouli, var. snavis. 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 Pogosiemon 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
