In the disposition of the sexes it agrees with Isachne, but differs 

 from it in habit, in the relative size of its glumes, and in the consist- 

 ence of its palese. From Chamseraphis this section differs only, we 

 are told by Mr. Brown, in the number of its styles. The curious 

 prolongation of the rachilla beyond the terminal spicula likewise 

 occurs in some genuine Panica.

Where the Malay peninsula terminates in the China sea, there is 

 a tongue of land, called by the natives Delhi Point, somewhere about 

 104 E. longitude, for it is not very correctly laid down. Reefs are

 is strewed with large masses of scoria many feet thick, hard, and 

 emitting a metallic sound. Specimens Nos. 1 and 4 will show the 

 kind of vesicular masses mentioned ; long lines of perpendicular strata 

 are found stretching generally parallel to the shore, from three to
