Blume gives as part of the generic character, the connivence of the teeth of the calyx ; 

 a character very difficult to observe in dried specimens, and which does not appear to me 

 to run through all the above species, which are too closely alhed together to be generi- 

 cally separated. The form of the anthers, and the bearded stamina, are constant in the 

 whole of them. Blume describes the stamina as declinate ; but if they are so in the hving 

 state it can only be in a very slight degree. This genus, different in habit both from 

 Mentha and Pogostemon, is intennediate between them in characters. 



13. Pogostemon. Desf. — Calyx aequalis, 5-dentatus. Corolla 4-fida, subbilabiata, 

 labio superiore 3-fido patente, inferiori integerrimo acuto subdeflexo. Stamina 4, exserta, 

 distantia, sul)declinata. Filamenta barbala. Antherae terminales, 1-loculares, rima trans- 

 versali dehiscentes.

Blume (Bijdragen, p. 827) describes another species, under the name of P. menthoides, 

 of which the filaments are without the hairs I have found on every other species both of 

 Pogostemon and Dysophyllum. If he be right in his description, either bis plant muse 

 belong to some other genus, or the character of this one must be modified accordingly ; 

 but not having seen his plant, I cannot determine this point. This genus has usually the 

 stamina slightly dechnate, and on this account would belong to the Ocymoideaj ; but the 

 declination is in general so slight as to be scarcely perceptible in dried specimens ; and 

 the close connexion between the two latter genera (which cannot be separated from one 

 another) and Mentha has induced me to place them in this tribe.
