found in India in the district between the Nilghiris and Ceylon, and 

 also in Ceylon itself, where it is very characteristic for the vegetation 

 of certain districts, and is said to grow at altitudes up to 5000 feet. 

 It grows to a height of 5 feet and more. As already mentioned above, 

 it is probably the wild mother-plant of citronella grass, and it has also 

 the same odour as the latter, but it only gives a small yield of oil, 

 of whose properties nothing is known. The Singhalese name for it is 

 "Mana", whilst in the Nilghiris it is known as "Bambe". 



5. Cymbopogon flexuosus Stapf (Syn. Andropogon flexuosus Nees ex 

 Steud., A. Nardus var. flexuosus Hack.), Malabar or Cochin grass, 

 is distributed in the Tinnivelli district and in Travancore. It was 

 found there only in the wild state, and not cultivated, as erroneously 

 stated in Gildemeister and Hoffmann's work The Volatile Oils, 

 p. 285, for this plant which yields the Malabar or Travancore lemon- 

 grass oil. Only during the last few years, large areas have been planted 

 there with this grass. According to Stapf, the oil which is known 

 in commerce as lemongrass oil is obtained from two wholly different 

 plants, the oil coming from the Malabar coast being produced from 

 C flexuosus Stapf, whilst the other species of lemongrass, designated as 

 C. citratus Stapf, yields an oil which, though very similar, is not identical 

 with the former; this matter is discussed more in detail further down. 



C. flexuosus appears to have often been confused with citronella 

 grass; in the Medicinal Plants of Bentley and Trim en, for example, 

 it is illustrated under the name Andropogon Nardus, but it differs from 

 the latter by the large, loose, grey- or slate-coloured panicles, of which 

 the particularly thin and long diagonals are curved and frequently 

 hanging down, and further by the less distinct spathes and the smaller 

 and usually very thin and sharp aristae. The sheaths of the ground- 

 leaves are somewhat narrower than those of citronella grass, and not 

 reddish inside. 



6. Cymbopogon coloratus Stapf (Syn. Andropogon coloratus Nees, 

 A. Nardus var. coloratus Hook, f.) is found from the Tinnivelli district 

 to the Anamalai mountains, and also in the district Karnatik (Madras 

 Presidency), and belongs to the lemon grasses of the Malabar district. 

 It differs from C flexuosus among others by the fact that it is much 

 smaller. An essential oil of this plant is not known. 



7. Cymbopogon citratus Stapf (Syn. Andropogon citratus D. C, A. Schoen- 

 anthus L., A. citriodorum Desf., A. Roxburghii Nees, A. ceriferus Hack., 

 A. Nardus var. ceriferus Hack., Schoenanthum amboinicum Rumph.), lemon 

 grass, in Malayan „Sereh". Contrary to Malabar grass, C, citratus 

 only occurs in the cultivated state. It is found in most tropical 

 countries, especially in Ceylon and the Straits Settlements, also in 

 Lower Burmah and Canton, Java, Tonquin, Africa, Mexico, Brazil, 

 the West Indies, French Guyana, Mauritius, Madagascar, New Guinea, etc.
