species which are popularly known as " Motia " and " Sofia, " although, up to date, these have not been recognized as botanically distinct.

That there is a difference between the two well-known varieties called " Motia" and "Sofia " is evident from the inferior oil yielded by the latter, though Botanists have so far been unable to accept such a classification.

Mr. R. S. Hole, the Forest Botanist, says —

" The structure of the flowers in all the plants is practically identical and I can find no characters of importance to separate them. All the " Motia " plants, however, differ from " Sofia " as regards the wider angle which the leaf blade makes with the culm, a character which was first noticed and published by Mr. Burkill. It is doubtful, however, how far this character will prove constant and we must cultivate under varying conditions of soil and moisture the different forms here at Dehra, keep them under observation, collect the flowers at different seasons and prepare oil from them, before we can hope to define satisfactorily constant forms of value."

Uses : — The oil is regarded as officinal in the Indian Pharmacopœia. This oil, occasionally called also Oil of Namur, was first brought to notice in 1825 by Dr. N. Maxwell (Calcutta Med. Phys. Trans., vol. i., p. 367), and it was further described in 1827 by Dr. Forsyth (Ibid., vol. iii., p. 213). From a series of trials instituted with it at Madras, by Drs. Cole, Kellie, and Hunter, it appears that as an application in rheumatism its efficacy is chiefly limited to recent cases. In the severer forms and in the chronic stage, the oil, even when undiluted, afforded only slight relief (see Madras Medical Reports, 1855, p. 431, seq.) Favourable reports of it have been received from Dr. W. Dymock, Dr. L. W. Stewart, Dr. 2E. Ross., &c. (Ph. Ind.) The oil is believed to have the property of curing baldness, and to be useful in neuralgia. " A spirit is distilled from the grass with spices, and is said to be useful in indigestion and fever" (Stewart). " The decoction of the grass is a febrifuge and I have used it in cases of cold and feverishness with benefit." (Asst. Surg. Bolly Ch. Sen in Watt's Die.)
