may 4, 1923 CHASE: IDENTIFICATION OF RADDI’S GRASSES 177 
Gaudichaud 288, Rio Janeiro, the type of Panicum auriculatum B 
fasciculosum Doell®* and of Panicum Januarium Mez, and Pabst 706, 
from Brazil, both in the Berlin Herbarium, belong to Panicum con- 
densatum Bertol. Of the eight collections cited by Mez*! under 
P. Januarium, Gaudichaud 288, Rio de Janeiro, is taken as the type, 
because Mez cites ‘‘Panicum auriculatum var. fasciculatum Doell” 
(error for fasciculosum), and this is the only specimen Doell cites for 
the variety. The specimen in the Berlin Herbarium bears this name 
in Doell’s script. The name in Mez’s writing is not Januarium but 
one that was not published. The species belongs in Hymenachne 
Beauv. as described by Chase,?2 Hymenachne condensata (Bertol.) 
Chase. The species is represented in the U. 8. National Herbarium 
by Wilkes Expl. Exped. 6, Rio Janeiro. 
70. PANICUM DONACIFOLIUM. “In sepibus prope fossas udas in 
viciniis Rio-Janeiro.”” The specimen consists of two flowering culms, 
both lacking the base, with auriculate-clasping blades. It belongs to 
the species at present known as Hymenachne auriculata (Willd.) 
Chase,®* or Panicum auriculatum Willd.,*4 the type specimen of which, 
labeled “‘Amer. merid. Humboldt,” was examined in the Willdenow 
Herbarium in the Berlin Herbarium. Since Raddi’s name is earlier 
it must replace that of Willdenow, Hymenachne donacifolia (Raddi) 
Chase. This species is represented in the U. 8. National Herbarium 
by Smith 2748, Santa Marta, Colombia; Eggers 14633, Balao, Ecuador; 
Goeldi 52, Para, Brazil: and Morong 693, Paraguay. 
Panicum cordatum Doell,®* the type of which, Glaziou 4326, Rio de 
Janeiro, so named in Doell’s script, was examined in the Berlin 
Herbarium, belongs to this species. 
71. Panicum paspALompEs. “Ad fossas udas prope Rio-Janeiro.”’ 
The specimen belongs to Panicum geminatum Forsk. as described by 
Hitchcock and Chase,?* North American Species of Panicum. 
72. PANICUM DIVARICATUM. “In sepibus proximus Rio Janeiro, ut 
etiam alibi, praecipue ad fossas udas.’’ Raddi does not publish this 
as his own species, but gives Linnaeus as author. The specimen is 
Lasiacis ligulata Hitche. & Chase.*7
