Leaves glabrous or sparingly pubescent, i'-3' 

 long, tapering to an obtuse callous tip. Scapes 

 slender, 2 '-20' tall, 2-4-angled, clothed with long 

 soft appressed upwardly pointed hairs; sheaths 

 equalling or shorter than the leaves; heads glo- 

 bose, i "-3" in diameter; involucral bracts ovate 

 or oblong, shorter than the flowers, usually 

 brown; flowers about i" high; scales brown, 

 spatulate, surrounded at the base by the yellowish 

 silky hairs of the receptacle and white-bearded 

 at the apex; perianth of the staminate flowers 

 short-stalked, pubescent at the base, woolly and 

 fimbriate at the summit ; segments of the pistil- 

 late perianth white, glabrous, obtuse; ovary 

 densely villous around the base; seeds strongly 

 ribbed.

 brown staminate ones impart a mixed gray and dark appearance to the heads. March-June. 



Family 17. BROMELIACEAE J. St. Hil. Expos. Fam. i : 122. 1805. 



PINE-APPLE FAMILY. 



Epiphytic herbs (some tropical species terrestrial), mostly scurfy, with elon- 

 gated entire or spinulose-serrate leaves. Flowers spiked, panicled, or solitary, 

 regular and perfect, usually conspicuously bracted. Perianth of 3 thin distinct 

 or somewhat united sepals, and 3 clawed distinct or united petals. Stamens 6, 

 usually inserted on the base of the corolla. Ovary inferior or superior, 3-celled; 

 ovules numerous in each cell, anatropous ; style short or elongated ; stigmas 3. 

 Capsule 3-valved in our species. Seeds numerous, the testa membranous. Em- 

 bryo small, situated at the base of the copious endosperm. 



About 35 genera and 900 species, all natives of tropical and subtropical America. 



i. DENDROPOGON Raf. Neogen. 3. 1825. 



Epiphytic pendulous much-branched plants, with very narrow entire leaves and yellow 

 or greenish flowers. Sepals distinct and separate or very nearly so. Petals distinct. Stamens 

 long, the three inner ones inserted on the bases of the petals; filaments filiform; anthers 

 linear. Ovary superior; style columnar; stigmas short. Capsule septicidally 3-valved. Seeds 

 erect, narrow, supported on a long funiculus which splits up into fine threads. [Greek, 

 meaning tree-beard.] 



About 3 species; the following is the type of the 

 genus. 



i. Dendropogon usneoides (L.) Raf. Long 

 Moss. Florida Moss. Fig. 1146. 



Renealmia usneoides L. Sp. PI. 287. 1753. 

 Tillandsia usneoides L. Sp. PI. Ed. 2, 411. 1762. 

 Dendropogon usneoides Raf. Fl. Tel. 4: 25. 1838. 



Stems very slender, thread-like, flexuous, 

 hanging clustered in festoons from the branches 

 of trees, 3-2o long, gray and, like the filiform 

 leaves, densely silvery-scurfy all over. Leaves 

 scattered, i'-^' long, scarcely *" thick, their bases 

 somewhat dilated ; flowers sessile and solitary or 

 rarely 2 together in the axils of the leaves; sepals 

 about 3" long, pale green ; petals yellow, the 

 blade about 2" long; stamens about as long as 

 the_ calyx; capsule linear, <)"-i$" long, at length 

 splitting into 3 linear valves.

 Mexico. Very widely distributed in tropical America. 

 Vegetable hair. Hanging, Spanish or Black moss.
