ODORIFEROUS GRASSES OF INDIA. 65 



variety "I Nard/US, to which it is joined by numerous intermedial e 

 forms. Some specimens of these, found in this Presidency, and 

 others in the N.-W-. Provinces, and kindly lent by Mr. Duthic of 

 Saharanpore, are laid on the table. 



A. citrattLS, D.C. This grass, the leaves of which arc sold in the 

 bazaar, .under the name of Oil and Lili Cha (green tea), yields 

 lemon-grass oil, or the " oil of verbena " of commerce. In India it 

 occurs in the cultivated state, being found only in gardens. In my 

 paper above-mentioned, I have, following Munro and other authors, 

 described this grass as growing wild in Ceylon, side by side with 

 A. Nardus. I pointed out the close resemblance it {A. citvatus) 

 bears to the latter {A. Nardus), and that this would seem to suggest 

 the idea that it is only a cultivated variety of A. Nardus. In 

 the monograph on Andropogone recently published for DeCandolle's 

 Prodromus, in April, 1 888, Professor Hackel says : " A. citralus, 

 mentioned by DeCandollo, in the catalogue of the Herbarium of 

 Montpcllier, without the description of flowers, belongs either to 

 A. Nardus or A. Sclttcua/tthus," thus confirming my surmise. 



Please compare plate 280 given by Wallich in his Plant ce 

 Asiaticce Rariores, under the name of Andropogon Sc/twiiaidl/us, with 

 the plate of Trimcn and Bentley above referred to, and the two 

 dry specimens exhibited here, one collected in the garden of the 

 Bishop of Damaun at Colaba, and the other sent by Mr. Duthic, and 

 marked A. Nardus. These specimens closely resemble each other.* 



A. Sclacnairfhus, Linn., known to Europeans as ginger-grass, and 

 to the people of this country as Rosha, Boos/ia, &c, is, as I said in 

 my former paper, the best known of all the scented Audro])<v/oux. 

 It is found growing wild all over India, Ceylon, Macao, and Africa. 

 In this Presidency it is common everywhere. Those who have 

 been in Poona or Mahableshwar will have found its hi<>h culms 

 hanging by the roadsides, specially as one approaches Panchgani. 

 In Khandcish, an oil named Rosha oil, is distilled from it. 



A. irr.veolor, Noes, Steud. Synop. Plant. Glum., Vol. I., p. ?jS*, is 



given by Hackel as a variety of A. Schcenanthus, Linn. It grows in 



Ceylon, the Nilghiris, Africa, and Mauritius; see a specimen on
