 the margin coarsely appressed-crenulate ; stipules deltoid-acuminate, lacini- 

 ate: flowers few in small mostly terminal clusters: involucre pyri form, 

 glabrous ; the lobes elongate-triangular, entire or nearly so, the 2 flank-

 stipitate ; appendages very narrow or wanting ; false gland aristate, 

 rising from the base of the sinus: capsule glabrous, ellipsoidal, 2.5 to

 the margins when young, soon glabrate ; stipules narrowly triangular, 

 fimbriate : flowers solitary, a single one accompan3'ing each pair of leaves, 

 on slender pedicels 2 or 3 mm. long: involucre campanulate, 1.5 mm. 

 long, glabrous outside ; the lobes triangular, about equal, hairy within ; 

 glands 3 or 4, brownish, mostly with suborbicular white appendages 

 1 mm. in diameter ; the 5th gland replaced by an elongated false-lobe 

 at the base of the shallcjor triangular sinus : ovary glabrous. — Morelos, 

 Puente de Ixtla, July 3, 1900 {Charles C. Deam, no. 25). Related to
