LepyrocUa Muelleri. — Benth. fl. Austral. VII. 216. 



It is ascertained now, that E. Brown's Lepyrodia stricta is 

 exclusively West Australian, as the inspection of the 

 original specimens has confirmed. 



CalorojpJms fastigiatus. — 

 Beatham (1. c. 237-240) proposes the union of the genera 

 Hypolaena and Calostrophus, giving preference to the 

 name of the former. In justice, however, to Labillar- 

 diere, who even illustrated Calostrophus with a good 

 figure four years before the publication of Hypolaena, 

 the name given by him should embrace the united 

 genera, the Greek Calostroj^hus being also significant 

 towards Eestio. 



Gentrolepis strigosa. — R. and S. syst., I. 43. 

 Includes Desvauxia tenuior of R. Brown, and seems distinct 

 from C. fascicularis. 



Centrolepis monogyna. — Benth. flor. Austral., YII. 205. 

 This, the Alepyrum monogynum, J. Hook, fl. Tasm. II. 77, 

 t. 138, is also admitted as a species by Bentham. 



Heleocharis acuta. — R. Br,, pr. 224. 



Bentham refers to this as distinct from H. palustris, not 

 admitting the latter as Tasmanian or even Australian. 

 Baeckehr (in Linnaea, XXXVI. 460) records distinctly 

 also as Australian, indeed almost as cosmopolitan, the 

 H. palustris. 



Isolepis crassiuscula. — J. Hook, fl. Tasm. II. 86, 1. 143 ; Scirpus 

 crassiusculus, J. Hook, in Benth. flor. Austral. VII. 326. 

 All workers on Cyperaceae concur that the genus Isolepis 

 is as artificially separated from Scirpus as Chaetospora 

 from Schoenus, and I gave expression to the same eifect 

 in the Fragm. phytogr. Austr. IX. 38. It remains there- 

 fore quite optional whether Isolepis and Chaetospora 

 should be adopted as full genera or merely as subgenera, 

 although on the presence or absence of hypogynous 

 bristlets, as a rule, is laid much stress in defining the 

 numerous other cyperaceous genera ; as a sequence it 

 almost becomes imperative to attach within the same 

 natural order on equal importance to the generic value 

 of an organ such as the hypogynous setae. There seems 

 thus no reason to change the nomenclature adopted for 

 the Tasmanian ccdsus. 



Cladium trifidum. — G-ahnia trifida, Labill. Non. Hall, plant, 

 specimen. I. 89, t. 116. 

 This plant proves that the disjunction of Gahnia from 

 Cladium is not advantageous, for so similar is this 

 species to C. filum, that most observers failed to recognise 

 any specific (much less generic) differences between them. 

 Both species stand ou record from the Derwent and
