646 MONOECiA POLYANDRiA. Sagittariit. 



• 

 Dr. Smith observes, in his description of S. sagittifolia, 

 that it discharges a white milky juice, a rare circumstance in 

 an aquatic plant. Our Bengal plant yields nothing of the 

 kind; whether this is a sufficient ground for considering ours 

 to be a distinct species, I will not presume to say, but must 

 observe, that I cannot discover any other difference. I do 

 not find that any use is made of the bulbs in Bengal.

 so as to occupy the whole of the centre of the flowers. An- 

 thers two-lobed. Hermaphrodite Jloivers, for there are no 

 male flowers, at least I have never found any, more numer-
