 middle lobe; column short; pollinia 2, on a wedge- 

 shaped stipe. About 20 species. Epiphytes of dwarf 

 stature, growing best on blocks; free-flowering; they 

 suffer from too much water at the root; give them a 

 warmhouse temperature. Prop, by division.

 sepals and petals obovate-lanceolate, inside maroon- 

 brown, with greenish tips, outside greenish; labellum 

 subquadrate, white, with a large purple spot on each of 

 the lateral lobes. Brazil. B.M. 5688. A.F. 6:609.

 disk. May. Cent. Amer. B.M. 7380. I.H. 24:282.

 becoming yellowish with 

 2 blood-red spots on the 

 disk. Philippines. T.Daw-

F. TRACY HTJBBARD. 



TRICHOL^ENA (Greek 

 for hair and mantle, refer- 

 ring to the covering of 

 silky hairs on the spike- 

 lets). Gramineae. Allied to 

 Panicum: spikelets loosely 

 paniculate, clothed with 

 long silky hairs; first 

 glume minute, remote 

 from the second; second 

 3836. Tricholasna rosea. glume and sterile lemma 



2-lobed, a slender awn from between the lobes. Species 

 10, all African, 1 extending to the Medit. region and 2 

 to India. 



rosea, Nees (T. violacea, Hort. T. grandiflbra, 

 Hochst. Panicum tonsum, Steud.). Fig. 3836. NATAL- 

 GRASS. Annual: culms usually geniculate at base, 1 J/-3 

 ft. high: panicle 3-8 in. long, the silky spikelets a rich 

 wine- color when fresh, 

 changing to purplish when 

 dry. S. Afr. R.H. 1897, p. 

 273. One of our most beau- 

 tiful ornamental grasses. 

 Sometimes called ruby- 

 grass. It has become natu- 

 ralized in parts of Fla. and 

 Calif. A. S. HITCHCOCK. 



TRICHOLEPIS (Greek, 

 hair and scale, the involu- 

 cral scales are narrow with 

 long hair-like tips). Com- 

 posite. Annual or perennial 

 herbs, which are branched 3837. Fructification of Tricho- 

 and unarmed: Ivs. alter- manes. (Enlarged.) 

 nate, entire, toothed or the 



lower pinnatifid: heads terminal, solitary, homogamous; 

 involucre ovoid or broader; bracts many-rowed, very 

 narrow, usually with long recurved hair-points: fls. all 

 hermaphrodite, similar and fertile, yellow, red, or 

 purple; tube slender; limb 5-cleft: achenes glabrous, 

 oblong or obovoid, ribbed. About 7 species, India. 



furcate, DC. Glabrous or puberulous herb, 1K~6 ft. 

 high, branched from the base: Ivs. 2-6x^-2^ in., 

 elliptic-lanceolate, acute or acuminate, denticulate, 

 short-petioled: head rather large, yellow; involucral 

 bracts needle-like. Himalaya. Grown for ornament. 



TRICHOMANES (Greek, soft hair). Hymenophyl- 

 Idcese. A group of filmy ferns distinguished by its tubu- 

 lar cup-like indusium and filiform elongate receptacle. 

 (Fig. 3837.) Very delicate in texture and capable of 

 being grown successfully only under shaded glass. Over 

 100 species are known. Various species may be found 

 in the collections of fanciers, but the following appear 

 to be the only ones regularly in the American trade. 

 For culture, see Ferns. 



radicans, Swartz. Lvs. 2-8 in. long, 1-1 J^ in. wide, 

 bipinnatifid; pinnae ovate, obtuse; indusia terminal, on 

 short lobes. Tropical regions, extending into the 

 southern states as far as Ky. 



Prieilrii, Kunze (T. dnceps, Hook.). Lvs. 12-18 in. 

 long, 6-12 in. wide, tri-quadripinnatifid; pinnae ovate- 

 lanceolate; sori 2-12 to a pinnule, small, in sinuses; 

 indusium with a much dilated lip. Trop. Amer.

TRICHONEMA: Romulea. 



TRICHOPILIA (Greek, hair and cap; the anther is 

 concealed under a cap surmounted by three tufts of 

 hair). Orchiddcese. Handsome orchids, usually grown 

 in pots, although epiphytal. 



Pseudobulbs crowded on the short rhizome, flattened 

 and often elongate, 1-1 vd., surrounded with dry scales 

 at the base: Ivs. large, solitary, erect, fleshy, keeled: fls. 

 abundantly produced on short, nodding or decumbent 

 scapes; sepals and petals narrow, spreading, often 

 twisted; labellum large, forming the most conspicuous 

 part of the fl., united with the column below, lateral 

 lobes convolute, middle lobe spreading; anther bent 

 over; pollinia on a triangular caudicle; clinandrum 

 fimbriately winged. About 20 species, ranging from 

 Mex. to S. Amer. The fls. keep fresh a long time, both 

 on the plant and when cut. They need an intermediate 

 or greenhouse temperature. If grown too warm, they 

 suffer. Prop, by division.
