STARCHES. 



of Benares, Chittagong, and Travancore, and eaten by the natives ; a very 

 excellent kind, called tikur, is also made at Patna and Boglipore from 

 the tubers of Batatas edulis" Aiuslie states C. anyustifolia to be the 

 Malabar species. 



Curcuma caulina. Graham. 



Linn. Syst. Monandria Monogynia. 



The fecula of the tubers, Mahableshwur Arrow-root. 

 Vernacular. Chowur, By. 

 Habitat. Mahableshwur. 

 Remarks. This is the undoubted source of Mahableshwur Arrow-root. 



Curcuma pseudo-montana. Graham. 



Linn. Sysf. Monandria Monogynia. 



The fecula of the tubers, Rutnagherry Arrow-root. 



Vernacular. Kutcherra (Dr. De Crespigny), Sinderbur, Sinder- 

 wanee Shindelwan, Hellownda (Graham), By. 



Habitat. The Concans. 



Remarks. I have not seen the Rutnagherry Arrow-root in flower, but 

 it is probably the plant described by Graham under the above name 

 from its resemblance to Roxburgh's C. montana. Is Graham's plant iden- 

 tical with Royle's C. Kuclioor of Sirmore and Bissehnr? 'The other Cur- 

 cumas on this side of India are, C. decipiem, Dalz. C. Zedoaria, Rox. and 

 C. Amada, Rox. Alpiaia Galanga, Swartz, is also indigenous, and can 

 yield Arrow-root. 



Canna glauca. Roscoe. Glaucous Indian Shot. 



Linn. Syst. Monandria Monogynia. 



The fecula of tubers. 



Vernacular. 



Habitat. South America. Naturalized in Bombay. 



Remarks. This plant yields a valuable starch, and is stated by Sim- 

 monds to be one of the sources of Tous-les-mois, which is obtained chiefly 

 from Canna edulis, Ker. Simmonds also gives C. coccinea, Roscoe, and 

 C Achiras, Bot. Reg. tab. 1358, as sources of that West Indian product. 

 But C. coccinea has a fibrous root like the C. indica, Roscoe, of Bombay 

 gardens, and the Achira of Peru is probably a variety only of C. edulis, 

 Ker. C. glauca flourishes luxuriantly in Bombay, but is not used. 

 " Portland Arrow-root" is prepared from the tubers of Arum maculatum, 

 Linn. Common Arum, Cuckoo Pint, Wake Robin, or Lords and Ladies 

 of Britain. N. 0. 257.
