 water ; styles several or all bifid. Spathe loosely enclosing the fruit, 

 inflated, filled with water, compressed, broadly ovoid, purple-banded 

 on the outside, mouth bidentate finally torn. Leaves originally some- 

 what stiff, fragile, bright pellucid green ; scape slightly flattened, 

 shortly 2- winged, gradually thickened a little below the spathe, 

 tetragonal, lateral angles acutely winged. Ovary in the several fruits

Boottia crassifolia Eidl., I.e., p. 239; Durand k Schinz, I.e.; 

 Wright, I.e., p. 9. 



As the flowers are ? and solitary in the spathes, the species 

 belongs to the genus Ottelia, as Welwitsch suggested, and not to 

 Boottia.
