9. TILLANDSIA, L. {exclus. spec.) 



Petals distinct. Stamens hypogynous, or nearly so, distinct. Style filiform : stigmas 

 3, contiguous, or spreading. Capsule septicide : valves at length flatfish, endoearp often 

 loosened : seeds 00, rarely few, fusiform : funiculi long, erect, usually dissolved into hairs 

 (the pappus) : pappus spreading from their base. Embryo free below the album6n,-^Leaves 

 entire ; flowers in spikes, rarely solitary, supported by a bractlet ; sepals nearly distinct, 

 or % of them united. 



No generic characters are to be obtained from the adhesion of the ovary-base (appearing 

 in T.flexuosa as well, as it has been stated to be in the original Vriesea-species), the corolla- 

 scales, the direction and the torsion of flower-parts : natm-al sections however result from 

 the inflorescence, the leaves, their covering, and less so fi'om structural characters, not yet 

 verified in all species. The stigmas need still to be compared in life. I retain such generic 

 distinctions as are based upon cohesion of parts, but even these are less satisfactory, while 

 the primary division of Tillandsiece depends upon. the dehiscence of the capsule, peculiar in 

 the best genera, and upon the structure of the seed. The pappus presents no sectional cha- 

 racters; all our species are provided with a pappus, except T. pu/chella, hnt I observed a
