 spreading hairs on the stems above each node, narrower and more obconic iiivolucie, 

 glands often with appendages and tlie larger hairy capsule.

 and 5 minute fringed lobes; glands \-\ lin. in their greater diam., 

 transversely oblong, all without or 2 or all with a small white petaloid 

 appendage. Ciipsule nearly 1 lin. in diam., somewhat acutely trigonous, 

 glabrous, exserted on a curved pedicel -J lin. long, which is dilated at
