BLAKE—REVISION OF RINOREA, 501 
subentire or remotely serrate, hirtellous, glabrescent ; racemes 6 to 8 cm. long, 
erect, hirtellous; pedicels 4 to 6 mm. long; sepals lanceolate, 1.5 mm. long, 
acute, 1-nerved, puberulous; petals lanceolate, 5 to 6 mm. long, acutish, sparsely 
pubescent dorsally, erect ; filaments much shorter than the anthers, the anthers 
oblong, unappendaged (according to description, but apparently figured as with 
2 appendages), the connective scales about one and one-half times as long, 
oblong-lanceolate, obtusish, woolly on the back below; ovary villosulous, the 
placentae 1-ovulate. 
TYPE LOCALITY: Southeastern Brazil, probably in the Province of Espiritu 
Santo. Type collected by Prince Maximilian von Neuwied. 
Not seen ; description condensed from Hichler’s original. To be distinguished 
from R. physiphora, its only close ally, by its shorter-petioled leaves, with 
cordate bases.

SPECIMENS EXAMINED: 
Brazit: Near Praia Grande, Rio de Janeiro, 1868, Netto (G). Rio de 
Janeiro, Wilkes Expedition (N). Without definite locality, Riedel 
(G, N, Y). 
This species is apparently known only from the vicinity of Rio de Janeiro, 
where it is common. St. Hilaire gives its native name as “lobolobo,” and 
states that the leaves become mucilaginous when cooked and are eaten by 
negroes. He believed that the plant might be improved by cultivation and be- 
come of value for food purposes, but I can find no record of any attempt to 
do this. According to Baillon, the bark of this species is bitter and astringent, 
and is used as a febrifuge. -
