 ceous beneath ; raceme dense, spiciform, downy ; calyx much longer than the pedicels, 

 about as long as the large bracts, half as long as the ringent, lurid-red (or yellow) corolla ; 

 petal-scale basilar, reniform-emarginate, entire ; anthers much shorter than the filaments. —

 lax, glabrescent ; bracts as long as or shorter than the pedicel ; calyx about as long as the 

 pedicel, \{-\) as long as the rosy, ringent corolla; petal-scale basilar, reniform, entire ; au-

14. P. angustifolia, Ait. Leaves linear-acuminate, spiny-denticulute, furfuraceous 

 beneath ; raceme lax, often branched below : bracts short, about as long as the pedicel ; 

 calyx longer than the pedicel, %{-%) as long as the red, ringent corolla ; petal-scale distant 

 from its base, dentate ; [appendage of the seed truncate] .—Redout. Lil. t. 76. — P. Redoatiana, 

 Schult. — Leaves 4"'-12''' broad j corolla about .20'" long ; the character of the seed, having 

 been taken from a scarlet-coloured, narrow-leaved Guiana specimen, is to be confirmed. — 

 Hab. Antigua!, Wullschl., Dominica! ; [S. Croix; Guiana!, on trees]. 



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 flattish, endocarp often 

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

 (the pappus) : pappus spreading from their base. Embryo free below the albumen. — Leaves 

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

 or 2 of them united. 



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

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

 scales, the direction aud the torsion of flower-parts : natural sections however result from 

 the inflorescence, the leaves, their covering, and less so from 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 Tillandsieat depends upon the dehiscence of the capsule, peculiar in 

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

 racters, all our species are provided with a pappus, except T. pulchella, but I observed a
