10 GRAMINE. 
Ovulum——(to determine the situation of the abortive style 
which ought to be opposite the large palea.) 
This plant I have understood, but on no satisfactory grounds, 
was known to Hamilton by the name Oryza coarctata. 
It differs from that genus somewhat in the consistence of 
the pales, in the arista being continuous, in the stami- 
na not becoming exserted ?, still more in the long stalk of the 
ovary, and perhaps in the ovulum, which appears to have at 
least one loose membranous coat, but on this I am not certain. 
And it is so distinct in habit, that I have little doubt of its 
being a new genus. 
` 1t is not as nearly allied to Oryza as Zizania ciliaris 
which differs only from Oryza in having no glumes whatever, 
a difference of less importance as there is a tendency to their 
suppression in rice itself. Our plant besides has not the 
cup-shaped apex of the pedicel, which both the others have.
