possibility of its occurrence in our area should therefore be kept in mind. It is 

 readily distinguished from H. hrevipe^ by its much larger capitula, which reach -To in. 

 across, and by its calyx-teeth being shorter than the tube. There is nothing in the 

 description of the mysterious Leucas g lobulifer a {Hussk. Cat. Hort. Bogor. alt. 133), 

 which finds a place in various works of reference and which is obviously not a Leucas, 

 to prevent it from having been Hyptis capitata in cultivation, as Hasskarl says, at 

 Buitenzorg. Hasskarl's small 2-fid upper lip may stand for the two upper corolla-lobes, 

 the lateral lobes of the lower lip being the two lateral corolla-lobes ; the concave 

 mid-lobe, largest of the three in what Hasskarl terms the lower lip, explains itself. 

 Every other character agrees with Hyptis capitata, a,nd the combination of characters 

 will fit no other Labiate known to the writer as likely to be in cultivation in Java 

 when Hasskarl wrote.
