36 MISSOURI BOTANICAL GARDEN. 
Presl described 15 new genera, of which three are now 
retained, viz.: Pereilema, Epicampes, and Cathestecum. 
The others have either been reduced to other genera or had 
previously been characterized. He described as new 334 
species of grasses, and very many of these are now main- 
tained as good species. Some have been reduced to varie- 
ties of other species, while not a few had already been 
published by older authors. 
The volume of Reliquiae Haenkeanae, in which the grasses 
are described, was published in 1830, and very naturally 
contains the original descriptions of a large number of new 
species. The work now is quite inaccessible to ordinary 
students; it has long been out of print and copies when 
obtainable are expensive. It is hoped, therefore, that the 
present paper illustrating some 68 types of Presl’s species 
of grasses, with the notes concerning some, will be of inter- 
est to American botanists. Only those species represented 
in the Bernhardi herbarium are referred to below. The 
citations of habitats are those given by Presl. 
I would briefly call attention to a few of the species in the 
list enumerated. 
Bromus secundus Presl is a variety of Festuca rubra 
with rather densely pubescent flowering glumes, found in 
Alaska. 
Bromus virgatus is Gouinia virgata Scribn. = Gouinia 
polygama Fourn. 
Paspalum kora Willd. = Paspalum scrobiculatum Linn., 
a species represented in the United States by No. 5760 
A. H. Curtiss, 1896, collected at Jacksonville, Florida. 
Poa secunda Presl appears to be without doubt Sclero- 
chloa californica Munro, which has heretofore included 
a large number of varieties or forms and a few species 
which botanists did not well know what to do with. The 
species of this group have recently been defined in Circular 
No. 9, Division of Agrostology, U. 8. Department of Agri- 
culture.
