are thus red in C. xanlhorliiza Roxb, in the "tenia lawac" they are light- 

 red, this difference is but little. As to the short pubescence of the leaves, 

 it is unknown how K. Schumann comes to this characteristic not mentioned 

 by Roxburgh, it seems to me of little value. 



The tenm-lawac is spontaneous in Java in the teak forests. Specimens 

 from Ngarengan (Rembang) and Tomo (West-Java) are cultivated here; 

 they have not yet flowered but are unmistakeable by the dimensions, and 

 colour of the rhizomes; They do not, however, always possess the peculiar 

 taste and smell of the cultivated form. 



There are also specimens from Mt Yang, 500 M. (Backer 9560) and 

 from Mt Idjen by Koorders in the Herbarium, probably belonging here, 

 but without notes sufficient for a certain determination. 



Outside of Java this species is known from Malacca, where it is 

 cultivated by the natives under the name "temii lawas" (Ridley 1. c.) Spe- 

 cimens cultivated in the Bzg. Gardens from rhizomes received from Singa- 

 pore with that name flowered here and proved identical with the Javan 

 "temu lawac." 



The type specimen as mentioned above was collected by Roxburgh 

 in Amboina yet apparently Rumph did not see it, for he certainly would 

 have mentioned the orange coloured filipendulous tubers, which so highly 

 struck . the attention of Roxburgh. He mentions however the name "temu 

 lawas" as given by the Balinese to the species called by him, not without 

 doubt, Tommon Zerumbet, the description of which is very obscure (Rumph 

 V. 169). The drawing added to this description and wrongly quoted by 

 many authors as representing C. Zedoaria Roxb. belongs to a central 

 flowering spec, (see above).
