TRICHOP1LIA 



1849 



2367. Fructification of Tricho- 

 manes. 



to which fact the cultivated species owes its ornamental 

 appearance. Allied to Panicum, from which it differs in 

 having the second empty glume (which, on account of 

 the first glume being small or wanting, is apparently 

 the first) provided at the base with a conical callus, and 

 this and the third glume more or less awned between 

 the cleft apex. 



rdsea, Nees (T. violacea, Hort. Panicum Teneriffce, 

 R. Br. ). First glume wanting; spikelets (second and 

 third glumes) clothed with violet silky hairs; awns 

 short or wanting; culm 2-3 ft. South Africa.

TKICH6MANES (Greek, soft Mir}. Hymenophyl- 

 lacece. A genus of filmy ferns distinguished by its 

 tubular, cup-like indusium and filiform elongate recep- 

 tacle. Fig. 2567. Very 

 delicate in texture and 

 capable of being grown 

 successfully only un- 

 der shaded glass. Over 

 100 species are known. 

 Various species may 

 be found in the collec- 

 tions of fanciers, but 

 the following appear 

 to be the only ones 

 regularly in the Amer- 

 ican trade. For cul- 

 ture, see Ferns. 



radicans, Swz. Lvs. 

 2-8 in. long, 1-1% in. 

 wide, bipinnatifld ; 

 pinnse ovate, obtuse; 

 indusia terminal, on 

 snort lobes. Tropical regions, extending into our 

 southern states as far as Kentucky. 



Prieiirii, 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, axillary; indu- 

 sium with a much dilated lip. Tropical America.

TBICHOPtLIA (Greek, hair and cap,- the anther is 

 concealed under a cap surmounted by three tufts of 

 hair). Orchiddcea?. About 20 species, ranging from 

 Mexico to South America. Pseudobulbs crowded on the 

 short rhizome, flattened, and often elongate, 1-lvd., sur- 

 rounded with dry scales at the base: Ivs. large, solitary, 

 erect, fleshy, keeled : fls. abundantly produced on short, 

 nodding or decumbent scapes; sepals and petals nar- 

 row, spreading, often twisted; labellum large, forming 

 the most conspicuous part of the flower, united with the 

 column below, lateral lobes convolute, middle lobe 

 spreading; anther bent over; pollinia on a triangular 

 caudicle; clinandrum fimbriately winged. The flowers 

 keep fre^h a long time, both on the plant and when cut. 

 Handsome orchids, usually grown in pots, although 

 epiphytal. They need an intermediate or greenhouse 

 temperature. If grown too warm, they suffer. Prop, 

 by division. 



Galeottiana, A. Rich. & Gal. Pseudobulbs narrow, 

 flattened, 5 in. long: Ivs. oblong, acute, about 6 in. long: 

 scapes short, mostly 1-fld. : sepals and petals cuneate- 

 lanceolate, yellowish green, sometimes with a band of 

 cinnamon down the middle; labellum trumpet-shaped, 

 whitish with some purple streaks and dots in the center, 

 and yellow in the throat. Aug., Sept. Costa Rica, 

 Mexico. I.E. 6:225 (as T. picta). B.M. 5550 (as T. 

 Turialwe). 



fragrans, Reichb. f. (PiUmna fragrans, Lindl.).

 Ivs. oblong-lanceolate, acute, 6-8 in. long: scape pen- 

 dent. 1 ft. long, about 6-fld.: fls. on pedicels 3 in. long; 

 sepals and petals spreading, linear-lanceolate, 2K-3 in. 

 long, wavy and twisted, greenish white; labellum folded 

 over the 'column, spreading in front, and somewhat 

 lobed. white with ' yellow stain in the throat. Summer. 

 Colombia. 'B.M. 5035.-Fls. almond-scented. 



n6bilis, Reichb. f. (Pilumna it6bili*, Reichb. f. ' 

 cdndida, Linden). Pseudobulbs large: Ivs. broadly 



oblong-acute: fls. white; sepals and petals linear-oblong, 

 acute, 2 in. long, scarcely twisted; Inlx-llum :

 19:94 (as T. frnyrans, var. nobilis). F.M. 1872:21 (as 

 T. fragrans), This has larger, stouter pseudobulbs and 

 shorter broader Ivs. than T. fragranx. The labellum is 

 larger and the petals shorter compared with the size of 

 the flower. 



tbrtilis, Lindl. Pseudobulbs oblong, compressed, 

 somewhat curved, 2-4 in. long: Ivs. solitary, oblong, 

 acute, 6 in. long: fls. solitary, on decumbent stalks 

 shorter than the Ivs.: sepals and petals linear-lanceo- 

 late, 2 in. long, spirally twisted, brown with yellowish 

 margins; labellum forming a tube around the column, 

 upper portion expanded, 4-lobed, white with crimson 

 spots, becoming entirely crimson within. Fls. pro- 

 fusely in summer and sometimes again in winter.
