Species 1 ; a Kunth (Enum, ii. p. 40) inter Luzuloides, a 

 Boeckeler (Linnsea, xxxv. p. 412) in Anosporum collocata; a 

 Bentham (El. Austral, vii. p. 264) et Steudel (Cyp. p. 315), C. 

 alternifolio &c. affinior habita. (Cf. ff. 7, 8, 9.) 



This is a very aberrant species ; even assuming, as I have 

 endeavoured to put forward, that the peculiar corkiness of the 

 cells of the nut is merely adaptative, there yet remains much to 

 connect it with Anosporum, i. e. to break down Anosporum as a 

 genus. On the inner face of the nut (fig. 8) two obscure chinks 

 can be made out which appear analogous with the correspondingly 

 situate deep grooves in the nut of C. cephalotes, which Boeckeler 

 interprets as indicating an absorbed perianth. The style is more 

 unlike that of Anosporum than of Cyperus proper ; it is deciduous 

 papillose-floccose nearly to the base, and more like that of some 

 Fimbristylis or Scirpus, whence E. Brown's excellent specific 

 name. The inflorescence will only do for this part of the genus 

 Cyperus, and has doubtless influenced Beutham in his view ; but 

 the spikelets themselves, contrd, have a hardness reminding much 

 of C. cephalotes. 



85. C. plattstvlis (B. Br. ! Prod. p. 214) ; robusta ; umbella 

 decomposita, densa, spiculis per 3-6 digitatis, pallidis aut aureo-
