92 ON TWO TUBERIFORM VEGETABLE PRODUCTIONS FROM TRAVANCORE. 



black continuous cuticle. The total absence of veins and different textui-e forbid its 

 junction with 3Iylitta. 



The second production, also sent by Dr. Waring to Mr. Hanbury from Travancore, is 

 known by the name of Carom-pallagum, which may be rendered Black Fallagnm, Pal- 

 lagum signifying a medicinal substance. It is dug from the chalk-beds in the mountains 

 Avhich separate Travancore from Tinnivelly. The hill people, who bring it occasionally 

 into Trevandrum for sale, state that it is the root of a small plant with a red flower. It 

 is much esteemed by the native doctors for various complaints. 



The account, however, which the natives give of its origin is evidently wrong ; for it 

 cannot be pretended that, like Pachyma, it may be a peculiar state of the root of some 

 Phsenogam. Its structure is in fact very like that of Mylitta australls ; and though there 

 is a slight difference in the outer coat, it is probably the same thing with the Ilylitta of 

 China, known under the name of Luy-imn, and to which Horaninow has given the name 

 of Mylitta lapidescens (' Catalogus Medicamentorum Sinensium,' Petropoli, 1856, p. 34). 



The specimens, indeed, are not so much advanced as those of the Luy-wan, so that the 

 peculiar sacs are few and only partially developed ; but there is no doubt that the struc- 

 ture of the two is identical.
