Epiphytic (or on rocks, etc.); leaf margins not armed with spines. 



Leaves very wide (up to 10 or 15 cm. wide) with a widely rounded mucronate 



tip and finely serrate margins 192. Hohenbergia pendulifera. 



Leaves narrower, at apex not widely rounded, marginally not serrate. 



Grayish-green, linear-leaved, "moss-like" plants hanging from branches ot 



trees 199. Tillandsia usneoides. 



More or less erect plants growing on limbs of trees or from crevices of cliffs, 

 not pendent. 

 Flowers few (1-4) on a slender scape-like stem about 1-2 dm. high; 

 leaves setaceous-filiform from short dilated sheathing bases. 



198. Tillandsia reciirvata. 

 Flowers mostly more than four and stem not scape-like nor filiform. 

 Leav'es up to 2 or 3 dm. long, linear-subulate and abruptly con- 

 tracted from a very short dilated base. . . 195. Tillandsia tenuifolia. 

 Leaves wider and with a longer dilated base. 



Basal leaves shorter than the stems; stems considerably branched; 

 bracts not closely imbricated. 

 Upper leaves of the stem merely clasping scales. 



194. Tillandsia uiricidata. 

 Upper leaves of stem with long acuminate points beyond the 



clasping base 193. Catopsis nutans. 



Basal leaves usually longer than the stems, or at least verj- little 

 shorter; bracts often closely imbricated. 

 Leaves with bladder-like dilations of the base, widely spread- 

 ing and recurved or twisted; bracts rather narrowly ovate, 

 1.5-2 cm. long, looser, not lustrous. 



197. Tillandsia Balbisiana. 



Leaves dilated but not bladdery at base, erect or somewhat 



spreading. 



Leaves rather rigid and involute; bracts broadly ovate, 



2-3 cm. long, closely imbricated, 2-ranked, keeled, 



lustrous 196. Tillandsia fasciculata.
