‘* A slender tree about 20 ft. high, with bright-blue flowers,

PRUNUS GUANAIENSIS Rusby, Mem. Torrey Club 6: 31. ‘A tree 
about 20 feet high, with white flowers, growing in forest-mould 
near river.” Coripata, April 9, 1894. (Vo. 2770.) The same 
as 7432 and Mandon 677. A form with narrower leaves, with 
cuneate base, distributed as *‘ 2770a,” may be distinct. 
Prunus Britronrana Rusby, Mem. Torrey Club 3°: 24. (lVo. 
z938.) The same as S2z. 
Rusus Bouiviensis Focke, Bremen Abh. 4: 158. 1874. (Or 
Fubus sp. nov.?) ‘* Grows in hedges, and climbs to a height of 
8 or 10 feet; the flowers white, the fruit edible. Local name 
‘Cari-cari.?. Abundant.” Coripata, April, 1894. (Vo. 2747.) 
The same as Rusby 468, in part. The limits of this species are 
extremely doubtful. Azsdy g68 includes two forms, which may 
well be distinct. 
RUBUS BOLIVIENSIS (or sp. nov.?). ‘Along roadsides, climbing 
to a height of 6-10 feet, the flowers light-red.” Coroico, July 
24, 1894. (Vo. 2376z.)° There is little doubt that this number 
represents a distinct species, but I do not care to publish it until I 
know it better. 
Rupus ciaucus Benth. Pl. Hartw. 173. (lVo. 78596.) The 
same as Ausby 471. 
Rusus mEcatococcus Focke, Bremen Abh. 4: 157. 1874. (Vos.
