TRI 



Trichope'talum. From thrix, trichos, a hair, and 

 petalon, a petal ; the inner perianth segments 

 are fringed. Nat. Ord. Liliacece. 



T. stellatum, the only described species, is a 

 curious, half-hardy perennial, with a thick 

 rhizome and greenish-white flowers, and suc- 

 ceeds best if planted out in a frame from 

 which the frost is entirely excluded. It was 

 introduced from Chili in 1828, and is increased 

 by division of the rhizome. 



Trichopi'lia. From thrix, trichos, a hair, and 

 pilion, a cap ; in allusion to the anthers being 

 concealed below a cap surmounted by tufts 

 of hair. Nat. Ord. Orchidacece. 



A small genus of very beautiful epiphytal 

 Orchids, natives of Central America and the 

 West Indies. The flowers are white, yellow, 

 pale pink, or greenish white. T. suavis, a 

 species from Central America, is one of the 

 finest of the genus. Its flowers are very large, 

 pale nankeen color, with white lip very clearly 

 marked with lilac, and are very beautiful and 

 fragrant. T. coccinea, T. crispa, T. fragrans 

 and T. tortilis are all desirable kinds. All the 

 species may be grown in a cool house, and 

 succeed best in pots. Syn. Pilumna. 



Trichosa'nthes. Snake Cucumber. From thrix, 

 trichos, a hair, and anthos, a flower ; the flow- 

 ers are ciliated. Nat. Ord. Ciicurbitacece. 



A genus of climbing annuals from China and 

 the East Indies, commonly known as Snake 

 Cucumbers. T. anguina(syn. T. colubrina) is a 

 very curious plant with white flowers, every 

 petal of which appears surrounded with long, 

 knotted fringe. The leaves and tendrils re- 

 semble those of the common Cucumber ; but 

 the fruit is curiously striped, and is so long 

 and narrow as to resemble a snake. Speci- 

 mens have, indeed, been grown more than 

 six feet long, and not thicker than the body 

 of a common snake. The plant is an annual, 

 a native of China, and is only worth cultivat- 

 ing as an object of curiosity. Many botanists 

 include Eopepon under this genus. 



Tricho'sma. Hair Orchid. From thrix, trichos, 

 hair, and kosmos, ornament. Nat. Ord. Orchid- 

 acece. 



T. suavis, the only introduced species, is a 

 very scarce and distinct epiphytal Orchid, in- 

 troduced from Assam in 1840. Its flowers 

 are white, striped with brownish-crimson ; 

 very showy and fragrant. It succeeds best 

 when grown in a well-drained pot or pan, and 

 when growing must be kept moderately 

 moist ; as it has no pseudo-bulbs, it must 

 never be allowed to get quite dry. Syn. 

 Caelogyne coronaria. 



Trichoste'ma. Blue Curls. From thrix, trichos, 

 hair, and sterna, a stamen, referring to the 

 slender, hair-like stamens. Nat. Ord . Labiatce. 

 A genus of native plants found in sandy 

 fields from New England to Kentucky. They 

 are of no horticultural value. 



Tricho'tomous. Branching in threes. 



Trico'ryne. From treis, three, and koryne, a 

 club; in allusion to the form of the capsules. 

 Nat. Ord. Liliacfoe. 



A small genus of green-house perennials 

 with fibrous roots, natives of Australia. The 

 species are easily increased by division, but 

 are more of botanical than horticultural inter- 

 est. 



TRI 



Tricuspida'ria. From tricuspis, three-pointed; 

 alluding to the petals. Nat. Ord. Tiliacece. 



A small genus of green-house plants, natives 

 of Chili. T. hexapetala is a very t>eautiful, 

 free-flowering shrub, producing pendulous, 

 conical blooms of thick, waxy texture, resem- 

 bling that of Lapageria rosea, and of the same 

 bright, rose color. The leaves are oblong- 

 lanceolate, serrated, or rarely entire. This is 

 the only species yet in cultivation, and is 

 propagated by cuttings of the half-ripened 

 wood. Syn. Crinodendron Hooker ianum. 



Tricuspidatus. Having three points. 



Tricy'rtis. Japanese Toad Lily. From treis, 

 three, and kyrtos, a convex; alluding to the 

 three outer sepals having bags at their base. 

 Nat. Ord. LiliacecB. 



T. hirta, the best known species, is a very 

 beautiful, hardy, herbaceous plant, found in 

 China and Japan. The flowers are axillary, in 

 panicles about six inches long, resembling, in 

 their peculiar form and markings, some of the 

 more singular Orchids. This plant is very 

 desirable for the open border. It produces 

 its flowers in October and November, at which 

 time the plant may be removed to the sitting- 

 room, and they will remain several weeks in 

 flower, after which they may again be returned 

 to the border. It was introduced in 1855 and 

 is propagated by division. 



Tri'dax. From treis, three, and akis, a point ; 

 alluding to the ray florets. 



A genus of Composite, natives of Central 

 America and comprising seven or more spe- 

 cies of hardy perennials of but little beauty. 

 T. bicolor rosea is a Mexican half-hardy annual 

 of comparatively late introduction and of easy 

 management. Its flowers are of a pleasing 

 rose color, the disk florets being yellow, and 

 are produced in profusion during the whole 

 season. The typical T. bicolor has the ray 

 florets pure white. 



Tridentate. Trident pointed ; when the point 

 is truncated and has three indentations. 



Trienta'lis. Chickweed Winter-green. A Latin 

 term signifying one-third of a foot high, in 

 reference to the stature of the plants. A 

 small genus of Primulacece, the species of 

 which are found in Europe and in cold, damp 

 woods from New Jersey northwards. They 

 are low, smooth perennials with simple, erect 

 stems, bearing a whorl of thin, veiny leaves at 

 the summit, from which spring one or more 

 slender peduncles supporting the pretty, 

 single, white, star-like flowers. 



Trifid. Split half-way into three parts. 



Trifoliate. Composed of three leaflets, as the 

 leaves of Clover. 



Trifo'lium. Clover, Trefoil. From treis, three, 

 and folium, a leaf ; three-leaved. Nat. Ord. 

 Leguminosce. 



Of this very extensive genus there are sev- 

 eral species under cultivation as forage plants. 

 They include T. pratense, the common Red 

 Clover, a native of Great Britain ; T. reftexum, 

 Buffalo Clover, indigenous in New York and 

 westward ; T. repens, White Clover, introduced 

 from Europe, but indigenous in the Northern 

 States ; and T. hybridum, or Alsike Clover, a 

 hybrid variety introduced from near Stock- 

 holm, Sweden. This is a very hardy peren- 

 nial sort, valuable for pasturage and soiling, 

 and being very productive and floriferous,
