 only in gardens. 



This plant seems to flower not infrequently in the Philippines ; there are specimens 

 from thence at Kew collected both by Vidal and by Loher. So far as is known, it has 

 flowered only three times in Europe : once in France, recorded by Pelletier (1844) ; 

 once in Italy, recorded by Tenore (1847) ; once in England, recorded by Sir W. J. 

 Hooker (1849) : Hooker's plant was obtained from Tenore. No flowering specimen 

 has ever been communicated from our area where, according to Wray and Curtis, it 

 is extensively cultivated by Chinese settlers. In the Pioyal Botanic Garden at 

 Calcutta the plant has been in continuous cultivation since 1834, when Wallich first 

 obtained it from Penang ; at Saharanpur, whence it was distributed from the 

 Calcutta Garden, it has also been long in cultivation. At Calcutta and at 

 Saharanpur all attempts to induce the plant to flower have consistently failed. 



This, which may be termed the Malayan, as opposed to the original or Indian 

 Patchouli, is not known to be cultivated anywhere in India except in botanical 

 gardens. 



There are indications that a third kind of Patchouli plant, the Chinese 

 Patchouli (Micvotoena cymosa, Prain), had atone time been introduced, not impossibly 

 by Chinese settlers, to Java. But its cultivation has not persisted in the Malayan 

 Archipelago, and there is no indication that it was ever introduced to the Peninsula. 

 The Chinese Patchouli seems at one time to have been cultivated to a considerable 

 extent in North-eastern India, and to have competed in the Calcutta market with 

 the Indian Patchouli [Pogostemon Heyneanus). Now, however, the Malayan 

 Patchouli, the product of Pogostemon Cahlin, appears to have so completely 

 supplanted both the others that neither are offered for sale, and the cultivation of 

 Pogostemon Heyneanus is restricted to native gardens in the Indian Peninsula, 

 while that of Microtoena cymosa only lingers in a few native gardens in the Khasia 

 Hills. 



In commercial samples of the leaves of Pogostemon Cablin, various extraneous 

 leaves are to be met with. The chief of these are leaves of Hyptis suaveolens, Poit., 

 in our area known as "Euku," also leaves of Urena lobata, Linn., known in our 

 area as "Perpulut." With Hyptis suaveolens, and under the same name "Euku," 

 are associated the leaves of Ocimum Basilicum, Linn., var. pilosum. These, how- 

 ever, are in much smaller quantity than those of the Hyptis.
