Cenchrus catharticus Delile, Cat. Hort. Monsp. 183$; Schlecht. Linnaea 13: nf °<Xn^, 

 Litt. 103. 1839. Apparently described from specimens grown in the botanical 

 garden at Montpellier from seeds sent from Nubia, Africa, by Dr. Lush. The 

 description, though inadequate, mentions the characteristic tomentose-ciliate 

 inner side of the inner involucral bristles. We are unable to verify the refer- 

 ence to the Montpellier seed catalogue of 1838. The full title as given by 

 Schlechtendal reads, " Index complectens semina in horto botanico regio Mon- 

 speliensi anno 1838 collecta, pro mutua commutatione oblata, additis caracter- 

 ibus specificis plantarum quarundam, vel ex toto novarum, vel accuratius 

 nuper observatarum. 8vo." This would seem to indicate that the species was 

 described in the index. Delile's name does not appear, but he was director
