MAY 4, 1923 CHASE: IDENTIFICATION OF RADDI’S GRASSES 175 
61. NAvICULARIA HIRTA. “In saltibus montosis prope  Rio- 
Janeiro.”” (The locality of this is given with that of N. glabra.) The 
specimen could not be found in Pisa but in the British Museum is a 
specimen bearing the name in Raddi’s script. The plant agrees with 
Raddi’s description and also with that of Panicum loliaceuwm Bertol.,?° 
(not Lamarck, 1791) which Raddi cites, having pilose glumes and well- 
developed wings on the lemma, pubescent sheaths, and blades 
puberulent beneath. Bertoloni refers to the wings of the lemma as 
nectaries. This species was referred by Nees?! to Panicum cand- 
icans Nees, but in that the appendages of the fertile lemma are reduced 
to scars. 
Doell2 reduces Navicularia hirta to “Ichnanthus planotis Trin.” 
making it var. 6 pilosus Doell. Doell gives Trinius as the author of 
I. planotis, but Trinius® published it as Panicum planotis. 
Trinius’s description (including three varieties) seems to include 
more than one species. A specimen in the Trinius Herbarium named 
‘Panicum planotis m. var 6” by Trinius and labeled “Rio Janeiro 86” 
is like the Raddi specimen. ‘Trinius’s brief description of 6 agrees 
with this plant. A specimen named “Panicum planotis m. var. a,” 
“Rio Janeiro 269” is a species of Panicum. This agrees with 
“Append. nullis” given in the diagnosis of var. a. Raddi’s specific 
name is the earliest tenable one of this species: Ichnanthus hirtus 
(Raddi) Chase. 
Schultes** changes Panicum loliacewm Bertoloni, not Lamarck, to 
Panicum Bertolonianum Schult. 
Except the two specimens mentioned I have seen none which belong 
to this species. 
62. NAVICULARIA GLABRA. ‘‘In saltibus montosis prope Rio- 
Janeiro.”’ No specimen of this could be found. Hitchcock inter- 
prets Raddi’s description and publishes the name Ichnanthus glaber 
(Raddi) Hitche. The specimen cited by Hitchcock, Rose 20181, 
“on Corcovado, Rio de Janeiro,” agrees perfectly with Raddi’s 
description. 
63. NAVICULARIA LANATA. pl. 1. f. 5. “In herbidis prope Rio- 
Inhumirim.”’ The specimen is an immature plant of Ichnanthus 
leiocarpus (Spreng.) Kunth (Panicum leiocarpum Spreng. 1820), the 
20 Opuse. Sci. Bologna 3: 408. 1819.
