20-50 cm. long., 1:0-3'0 em. lat., margine leviter undulata, supra viridis, subtus 
albida; costee secundariæ 5-8 alternatim insertæ, sensim arcuate ; petioli non ultra

[ Paraguaria. | 
To this species, of which authentic material does not exist in England, undoubtedly 
belong specimens recently collected by Mr. Graham Kerr on the Pilcomayo River and 
named by Mr. N. E. Brown, to whom and to Mr. Jackson’s invaluable ‘ Index’ I am 
indebted for the reference to Mueller’s paper. Dr. Morong also brought back the same 
handsome plant from the Pilcomayo. 
The original collector of this plant was the late Dr. Weddell, since whose time it was 
not collected until the Pilcomayo explorers came upon it. There is some doubt where 
Weddell actually gathered his specimens. In his time the Brazilian frontier did not 
extend south of Coimbra, and inasmuch as he spent sixteen days in botanizing at Olympo, 
in the territory now disputed between Paraguay and Bolivia, it is most probable that 
he there found the plant now under notice. His party may well, however, have camped 
for the night upon the eastern side of the river, now, as far as the Rio Apa, in Brazilian 
hands, or indeed he might have secured the plant at some spot between Coimbra and the 
small Rio Branco, at the junction of which with the Rio Paraguay stands the boundary- 
mark erected by the Brazilio-Bolivian Boundary Commission. In either event the 
locality would nowadays be a Brazilian one. The extension in the range of this species to 
Corumbá is interesting. |
