 over the cylindrical 4 cm. long, and 1.8 cm. thick neck : leaves lanceo- 

 late, 1.2 dm. long, 1 to 2.5 cm. broad, narrowed at both ends, obtusish, 

 entire, glabrous on both surfaces : peduncle 2 to 2.5 dm. long : spathe- 

 valves lanceolate, attenuate, 4 to 5 cm. long, 12 mm. broad at the base, 

 thin and scarious: flowers 4 to 6 : perianth-tube 3.5 cm. long; seg- 

 ments somewhat exceeding the tube, narrow, 3 to 4 mm. broads 

 staminal-cup rather narrowly funnelform, 1.8 to 2 cm. high; free 

 portion of filament about equalling the tube : style slender, greenish ; 

 stigma slightly overtopping the anthers : ovary sessile, bearing two 

 ovules in each cell. — Mexico. State of Hidalgo : hillsides near Tula,

 1 to 2 dm. high, simple below, branched above, erect or very slightly 

 flexuous, hirsutish-pubescent to nearly glabrous : leaves linear-attenuate, 

 0.5 to 1.5 dm. in length: inflorescence branched, bearing several short- 

 pedunculate spathes ; peduncles mostly less than 1 cm. (rarely 1.5 cm.) 

 long ; bracts of the inflorescence foliaceous, 6 cm. or less in^ length, 

 ciliate: spathe of two slightly unequal bracts, 13 to 16 mm. in length, 

 rather strongly nerved, glabrous, the inner bract usually somewhat ex-
