1. Dendropogon usneoides (L.) Raf. Scurfy with silvery-gray scales. Stems 
string-like, spiral-zigzag, hanging in festoons 1-6 m. long, from the branches of trees: 
leaves scattered, slender, linear-filiform, 2.5-8 cm. long, pubescent like the stem: flowers 
fragrant, especially at night: peduncles shorter than the leaves: sepals green, oblong or 
oblong-lanceolate, 5-7 mm. long, acute: petals linear-spatulate, about twice as long as the 
sepals, their spreading tips yellowish green: capsules linear, 15-30 mm. long.  [ Tilland-

2. TILLANDSIA L. 
Rigid epiphytes, or rarely terrestrial herbs. Stems firm, often scape-like. Leaves 
mainly basal, commonly crowded, mostly dilated or saccate at the base, tapering to the 
apex, entire or variously toothed. Flowers perfect in terminal simple or branched spikes. 
Sepals 3, firm, distinct. Petals 3, deciduous, with erect claws and narrow blades. Stamens 
6: filaments free. Style filiform. Stigmas spreading. Ovules ascending. Capsule oblong 
or narrowly prismatic, septicidally 3-valved. Seeds nearly erect from an erect stalk, 
which separates into delicate hairs, acute. Our species are all epiphytic. AIR PLANT.
