FLORA OF MADAGASCAR. 283 
Mauritius, fide Bojer. (Ab insulis Mascariensibus in Kew 
nondum recepta.) 
Isolepis Micheliana, Reem. et Sch. Syst. ii. p. 114, has the 
glumes attached in a true spire to the top of the spikelet; the 
distinction between this and Cyperus pygmeus is easily seen in 
the fruit-spikelets. In the young spikelets the upper part of the 
spikelet is often not developed; in the fruit the notches on the 
rhachidia can be observed after the nuts have fallen. The nut 
of Isolepis Micheliana has the outer hyaline cells large, thick, 
quadrate; so that the margin of the nut under the microscope 
appears surrounded by a glistening, barred edge, a structure 
common in Isolepis &c., but occurring in no Cyperus. The nut 
moreover in Isolepis Micheliana is narrowly oblong, suddenly 
narrowed at the apex.
