nate the recurvedly divaricated branch, and incline down- 

 wards as well as the flower. 



The species is of the same division as. Cactus speciosus 

 already figured in this work (v. 4. foK 304). It has how- 

 ever sevend peculiar features, of which a ringently slanted 

 reflexed expansion of the flower, ascending stamens, and 

 crescentwise foreshortened joints of the branches seem the 

 most prominent. 



Stem very short, soon and repeatedly divided ; branches 

 widely and divaricately extended, horizontally recurved, 

 foliaceously compressed, the edges perpendicular, glaucous, 

 jointed, the joints cuneately oblong, lunately truncate at 

 the upper end, about an inch long, with a few irregular 

 axillary pencilled notches at the edges.
