Schistogyne pentaseta. 



Young stems and flowers minutely gray-downy, the lower

 oles at length 12 mm. long, and recurving, channelled above, 

 slightly dilated at the base. Blades 3 to 5 cm. long, i to 2 cm. 

 broad, ovate with deeply cordate base, the sinus narrow or 

 closed, the lobes rounded; the summit regularly acuminate

 side, the finer slender venation loosely reticulate. Peduncles 

 shorter than their le'aves, slender, terete, ascending, few flowered. 

 Calyx parted to the base, the lobes 5 or 6 mm. long, lanceolate,

 lobes 7 mm. long, narrow, regularly acuminate from the base. 

 Ligules of the crown linear, erect, as long as the androecium. 

 Stigmatic appendages 5, nearly i cm. long, filiform and attenu-

 which is a little longer than the stamen-column. 



Specimen unique. Collected in Yungas, Bolivia, by M.

 thirds of the way, the lobes ovate, acutish. Crown about
