6. CATHEA Salish. 
Seape erect from a solid tuber, sheathed below by the base of the 
grass-like leaf, naked above, bearing several large flowers, with lanceo- 
late-ovate spreading sepals and petals nearly alike, lip (the ovary or 
stock not twisting) brought to the upper or inner side of the flowers 
(dilated at apex, bearded on face, narrowed to a hinge-like claw), the 
free slender column winged at apex, terminal lid-like sessile anthers, 
and the 4 pollen-masses (of soft powdery grains) lightly connected by 
delicate threads. 
1. C. tuberosa (L.) Salisb. Leaf linear: scape (8 dm. high) 2 to 6-flowered: 
flowers 2.5 em. broad, pink-purple: lip as if hinged at the insertion, beautifully 
bearded toward the dilated summit with white, yellow and purple clavate hairs, 
(Limodorum tuberosum L, Calopogon pulchellus R,Br.)—Moist ravines, near the Pecos. 
7. HABENARIA Willd. (REIN-ORCHIS.) 
Herbs, with fleshy fibrous roots, leafy stems, spiked flowers, nearly 
equal sepals (the lateral reflexed) and petals, pendent lip spurred 
below, contiguous and nearly parallel anther-cells, 2 pollinia of coarse 
waxy grains, and 2 naked glands. 
1. H. flava (L.) Gray. Stems 15 to 30 em. high: leaves ovate-oblong or oblong- 
lanceolate, the upper linear-lanceolate and pointed, passing into the bracts of the 
elongated (at first dense) raceme: lip furnished with a tooth on each side and a 
strong nasal protuberance in the middle of the base, oblong, truncate-obtuse, about 
the length of the sepals, half the length of the slender clavate spur: glands dilated 
orbieular and incurved. (Orchis flava L. H. virescens Spreng.)—From Hockley to the 
Trinity. 
BROMELIACER. (PINE-APPLE FAMILY.) 
Herbs (or searcely woody plants), the greater part epiphytes, with 
long rigid persistent scurfy leaves, 6-cleft perianth free from the ovary, 
6 stamens, introrse 2-celled anthers, and a 3-celled 3-valved berry-like 
fruit with stalked seed. 
1. Hechtia. Tall diwcious plants: not epiphytes. 
2, Tillandsia. Flowers perfect: epiphytes. 
1. HECHTIA Klotsch. 
Terrestrial herbs, with densely rosulate long rigid strongly spinose- 
dentate leaves, a long terminal peduncle bearing a large panicle (or 
raceme), free ovate imbricate sepals, the slightly connate petals a little 
longer, stamens in the staminate flowers (staminodia in the pistillate) 
atlnate to the base of the corolla, and a 5-suleate pod with short-appen- 
dliculate seeds. 
1. H. Texensis Watson. Leaves 3.5 to 4.5 dm. long, 3 to 5 em. broad at base, 
white scurfy beneath, glabrous above, with 10 to 12 large curved teeth: fertile 
flower-stems 6 to 12 dm. high, bearing a simple pubescent panicle (6 dm, long) with 
ascending branches: flowers solitary and sessile along the branches, subtended by 
a broadly deltoid-ovate scarious brownish bract: sepals broadly ovate, acute, 4 mm,
