PATCHOULI. 307 
according to Mr. Thiselton Dyer (‘ Kew Bulletin,’ March 1888, 
p. 74), there appears to be evidence of the existence of a plant with 
a patchouli odour, native to Khasia and Assam, which is widely 
different from any form of Pogostemon Patchouli, although it may 
have the true odour and be of commercial use in India. It is 
mentioned in the ‘Flora of British India,’ iv. p. 624, as “a 
doubtful Plectranthus (Plectranthus Patchouli, Clarke).” He 
adds :—“ There is no inherent scientific improbability in widely 
different plants elaborating the same essential oil.” 
Other varieties of Plectranthus are much esteemed in India for 
their perfume, as the P. aromaticus, Roxb. (Flor. Ind. 1. p. 466), 
synonymous with Coleus aromaticus *, figured by Rumphius +, and 
in the ‘ Botanical Register,’ tab. 1520. It is mentioned by Royle 
in his ‘Illustrations of the Botany of the Himalayas,’ i. p. 303. 
The vernacular name in India for this plant is Pathor chur—con- 
sequently considered distinct from the patchouli, which is equally 
widely known as Pucha-Pat. 
Amongst other plants to which the patcbouli plant is described 
as having an affinity is, according to Dr. Wallich {, the Marruéium 
odoratissimum Betonice folio of Burmann’s ‘Thesaurus Zey- 
lanicus.’ 
Its odour has likewise been compared with that of Gendarussa 
vulgaris, Nees. .This is described by Wallich, Plant. As. Rar. ii. 
p. 104; DeCandolle, Prod. xi. p. 410; Wight, Icones, tab. 468 ; 
Rheede, Hortus Malabaricus, ix. tab. 42 ; and is also figured in the 
Botanical Register, tab. 635. It is the Gandharusa of Rumphius, 
Amboinensis, iv. p. 70, tab. 28, and the Justicia Gendarussa, Linn. 
Sp. Pl. ed. Willd. i. p. 87, under which name it is described by 
Dr. Roxburgh, Flor. Ind. i. p. 129, as a handsome shrub indige- 
nous on the Malay Islands, common in gardens in India, growing 
readily from cuttings, and flowering during the wet season. The 
bark of the young parts is generally dark purple and very smooth, 
but in some varieties green. The branches are numerous and 
straggling except when cut back. The leaves are opposite, short- 
petioled and lanceolate, frequently a little scolloped, smooth; the 
nerve and veins dark purple, from 3 to 6 inches long, and from 
half an inch to an inch broad; spikes terminal, erect, verticilled.
