 Ubi, or, as it is often called by the Mexicans, Agua Bonita. 



GiLiA GLORIOSA (Plate IX). Shrubby, densely branched 

 and forming rounded clumps 3-4 feet high, and as broad, 

 glandular-pubescent, strongly spinose from the persistent 

 divaricate leaves, which in the older branches remain as 

 blackened thorns subtending crowded fascicles of much 

 shorter simple acicular ones : principal leaves stout-subulate, 

 an inch long or less, with four remote subulate lobes, the 

 lower near the base, those of the axillary fascicles flattened, 

 acerose, not half as long: flowers on short peduncles from 

 the upper axils: calyx 10-12 mm. long, nearly twice the length 

 of the peduncle, the linear-acerose lobes nearly as long as 

 the tube, which is membranous in the intervals: corolla 

 pale pink, or nearly white, shading into rose-color; tube 

 funnelform, twice as long as the equally-cleft oval, entire 

 lobes, and. three times as long as the calyx; filaments
