boellia Linn, and Juss., and described and figured two species. Under the 
first, 0. incurvata. are cited the descriptions of Aegilops incurvata L. and Rott- 
boellia incurrata L. f. Under the second, 0. corymbosa, are cited the descrip- 
tions of Aegilops exaltata L. and Rottboellia corymbosa L. f., the latter of which 
is based on Aegilops exaltata, the specific name being changed because of Rott- 
boellia exaltata L. f. appearing earlier on the same page of the Supplementum 
(1781, p. 114). The generic characterization covers both grasses; but the first 
species is more completely described, Gaertner not having any fertile flowers of 
the second, of which he remarks that it might prove to be very closely related 
to Digitaria if the flowers were better known. It would therefore seem neces- 
sary to consider the first species, 0. incurvata, as the type of the genus Ophiuros. 
As Aegilops exaltata is not now considered to be congeneric with 0. incurvata 
it must be referred to another genus. In 1829, Kunth (Revision des Graminees, 
vol. 1, p. 153) published the genus Mnesithea with one species, M. laevis, 
based on Rottboellia laevis Retzius. As this grass is considered to be congeneric 
with the species received as Ophiuros corymbosa, the latter is here placed in 
the genus Mnesithea, the earliest specific name, exaltata, being restored.
