This Brazilian plant would appear to have been discovered by 
Herr von Martius! near Mandiocca and Boto Fogo, also near 
Capocabara: we saw his specimens. Prince Max von Neu Wied! 
found it near Rio Belmonte. Luphnath! collected it in the 
woods of Capocabona (perhaps the same as Martius’ Capocabara) 
on decayed leaves. Beyrich! gathered it near Novo Friborgo. 
A. de Chamisso! found it near St. Catherine. Riedel! collected 
it near Mand (so they wrote the place on the label of the plant 
given from St. Petersburg Botanic Garden) and Rio Janeiro ; 
collected also there by Gaudichaud ! 
Roots terete, acute, villous. Stems short, ascending, with a few 
rosulate leaves. Leaves petiolate, the petioles partly sheathing at. 
their base, cuneate-oblong, acute, adorned on the upper surface 
with silvery net-work or a silvery disk. Common flower-stalk 
glandular-hairy, elongated, with generally five acute hairy short 
distant sheaths. Raceme many-flowered. Flowers crowded. Braets 
lanceolate-acuminate, one-nerved, glandular-hairy outside, nearly 
equalling in length the curved stalked ovary, covered with glan- 
dular hairs. Perigone milk-white. Sepals and tepals with a 
median black streak in the middle, seldom reaching to the base, 
never to the tips, quite smooth outside, or with a few glandular
