C. B. Clarke, in Hook. f. Fl. Brit. Ind. 6: 651 (1893), attributed the genus Bul- 

 bostylis to Kunth (Enum. PI. 2: 205. 1837), citing the following combinations: B. 

 barbata Kunth, Enum. 2: 208, B. capillaris Kunth, Enum. 2: 212, and B. puberula 

 Kunth, Enum. 2: 213. Kunth, however, merely suggested that one of his sections 

 of Isolepis could be regarded as a separate genus and mentioned Bulbostylis as z 

 suitable name. In fact, he treated this name as a synonym in his mdex^ by italicis- 

 ing it, and, after mentioning it (p. 205) in a short description of a section of Iso- 

 lepis, proceeded to describe all the members of the section as species of Isolepis. 

 Kunth, therefore, is doubtfully the author of Bulbostylis, and certainly not the au- 

 thor of the combinations under this name attributed to him by Clarke. It seems, 

 therefore, unfortunate that "Bulbostylis Kunth" has been conserved, against Bul- 

 bostylis DC. (1836), Bulbostylis Stev. (1813), and Stenophyllus Raf. (1825).
