208 HEXANDRIA TRIGYNIA. RlimeX. 



Panicles oblong. Flowers solitary, valves of the calyx 

 equal in length, and awnless, but amplyciliate on the 

 back. 



Pharus ciliatus. Retz. obs. 5. p. 23, 



A native of Bengal, where it occupies with its primitive 

 roots the margins of pools, lakes, &c. of sweet water, 

 sending forth innumerable, several-fathoms-long, float- 

 ing stems, and branches over the surface of the water, 

 to a much greater extent than L. aristaia, which grows 

 in the same manner, but rarely extends more t&an a few 

 feet. Cattle are fond of the former. 



Compare with Leersia hexandra of Swarf z, and Leer- 

 sia australis Brown's Prodromus, In both the foregoing 

 species I have never found the flowers completely herma- 

 phrodite.
