 ridges and 2-beaked at the apex. — Rich woods, e. Mass. to Ont. , Dak. and southw. 

 'Ji. U. grandiflbra Sm. Yellowish green, not glaucous ; stem naked or with 

 a single leaf below the fork ; leaves whitish-pubescent beneath, usually some-

12. OAKfiSIA Wats. 



Flowers resembling those of Vvularia, but the segments obtuse or acutish, 

 carinately gibbous and without ridges within. Capsule membranous, elliptical, 

 acutish at each end or shortly stipitate, triquetrous and acutely winged, very 

 tardily dehiscent. Seeds globose, with a very tumid spongy rhaphe. — Stem 

 acutely angled, from a slender creeping rootstock, with sessile clasping leaves 

 scabrous on the margin, and 1 or 2 flowers terminal on slender peduncles but 

 soon appearing opposite the leaves by the growth of the branches. (Dedicated 

 to William Oakes, New England botanist, 1799-1848.)
