inches long, with the lamince f to 1 inch across ; the leaflets similar 

 to those of O. acetosella. Stipules ^ inch long, adnate to the 

 leafstalk ahrupt at the apex, fringed with hairs. Peduncles when 

 mature 1^ to 3 inches long. Bracts 3 or 4, very narrow. Pedicels 

 when in fruit equal to or a little shorter than the capsule. 

 Flowers f inch across, hright yellow. Sepals oval-lanceolate, with 

 adpressed hairs. Petals oblong-oblanceolate. Capsule three to five 

 times as long as the sepals, from -^ to f inch long, with 5 prominent 

 angles. Seeds reddish-brown, obovate-oval, flat, with very deep 

 transverse ridges. Plant light, rather gi'eyish-green, more or less
