I). Arandastrum appears to extend from Sumatra westward to 

 Singapore, Malacca, Perak, Pahang, Rangoon, and the Andaman 

 Islands ; and D. cannaformis from Java, Borneo, and the Philip- 

 pines, eastward to New Guinea, the Aru Islands, Admiralty Islands, 

 Solomon Islands, and the New Hebrides. D. cannaformis is very 

 common in the Philippines, being found in Miudauao, Palauan, 

 Mindoro, Culion, and in numerous provinces in Luzon. 



The foregoing have been so completely confused with Phrynium 

 dichotomum Roxb., now referred to Schumannianthns Gagnep., that 

 a revision of the synonymy of this genus also seems desirable; — -

 new, appears to be on the increase, and which would seem to 

 invalidate the principle of binominal nomenclature, already en- 

 dangered by the American method of combining the varietal name 

 with that of the species. An example will show more clearly and
