1919] Farwell,— Bromelica, a new Genus of Grasses 77 
in not possessing the spine-like elongation of the rachilla and in having 
glumes shorter than the lower floret. A genus of the Festuceae must 
then be sought for these species and amongst those genera having 
many nerved lemmas. They do not belong to Festuca because the 
lemmas are not entire. They do not belong to Bromus because the 
grain is not adherent to the palet nor pubescent at the summit. They 
do not belong to Melica because the lemmas are not subcoriaceous 
and the uppermost do not form a convolute club-shaped mass but are 
distinct. In Bromelica the glumes and lemmas are membranous, the 
former being somewhat unequal and shorter than the lowest floret; 
the latter are acute, notched or bidentate, generally with a terminal 
awn formed by the excurrent midrib between the teeth, the upper- 
most being similar to the others and distinct, the uppermost floret con- 
sisting of a single lemma only. Thus delimited, Melica and Bromelica 
consist, each of a clear, homogeneous group of species; united, Melica 
is a heterogeneous group. Bromelica is almost exactly intermediate 
between Melica and Bromus, with closer relationship to the latter than 
to the former, which is exemplified by habit and by the characters of 
the glumes and lemmas; if Bromelica is retained in Melica there is no 
good reason why Melica in its entirety should not be united with 
Bromus.
