HENDERSON'S HANDBOOK OF PLANTS. 



TRI 



ceedingly beautiful plant. Petals maroon 

 brown inside, and yellowish green outside; lip 

 large, white, with two bright purple spots. 

 One or two other species have very beautiful 

 flowers. They should be grown on blocks or 

 cork, or in small baskets in a moderate tempera- 

 ture. They bloom freely, and require but little 

 care. Introduced in 1835. 



Tricholeena. From thrix, a hair, and cUaina, a 

 cassock. Linn. Triandria-Digynia. Nat. Ord. 

 tframinaceai. 



A small genus of very pretty grasses, gener- 

 ally included in the genus Panicnm. A few are 

 found in collections of ornamental grasses in the 

 green-house. 



Trichomanes. From thrix, a hair, and manos, 

 soft; the shining stems appear like soft hair. 

 Linn. Cryptogamia-Filices. Nat. Ord. Polypo- 

 diacece. 



An extensive, varied, and beautiful genus of 

 Ferns, found abundantly in the moist, shady 

 woods of the tropics in both the Old and 

 New Worlds. T. radicans, a beautiful species, 

 is found on the coast of Ireland. Many of the 

 species are cultivated for the beauty of their 

 fronds, which have an almost transparent ap- 

 pearance. Propagated by division or from 

 spores. 



Trichonema. From ihrix, a hair, and nema, a 

 filament; stamens clothed with minute hairs. 

 Linn. Triandria-Monogynia. Nat. Ord. Iridacece. 

 A genus of beautiful little crocus-like, bulbous 

 plants, with red, yellow, purple, and white 

 flowers, borne singly on slender scapes. They 

 are natives of Spain, Italy, and the Cape of Good 

 Hope. Like most bulbs from those localities, 

 they require to be grown in the green-house. 

 Propagated by offsets. Introduced in 1818. 

 Trichopilia. From Ihrix, a hair, andpilion, a cap ; 

 in allusion to the anther being concealed below 

 a cap surmounted by tufts of hair. Linn. Gy- 

 nandria-lfonandria. Nat. Ord. Orchidacece. 



A small genus of very beautiful epiphytaFOr- 

 chids, natives of Central America and the West 

 Indies. The flowers are white, yellow, pale 

 pink, or greenish white. T. snavis, 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 

 clear lilac. It is very beautiful and fragrant. 

 All the species may be grown in a cool house, 

 and succeed best in pots. 



Tricb.08antb.es. Snake Cucumber. From thrix, a 

 hair, and anthos, a flower ; the flowers are ciliat- 

 ed. Linn. Monoecia^Decandria. Nat. Ord. Cacur- 

 bitacefK.. 



A genus of climbing annuals from China and 

 the East Indies, commonly known as Snake Cu- 

 cumbers. T. colubrina is a very curious plant 

 with white flowers, every petal of which appears 

 surrounded with long, knotted fringe. The 

 leaves and tendrils resemble those of the com- 

 mon Cucumber; but the fruit is curiously 

 striped, and is so long and narrow as to resem- 

 ble a snake. Specimens have, indeed, been 

 g rown , more than 8ix feet Ion 8> and not thicker 

 than the body of a common snake. The plant 

 is an annual, a native of China, and it should be 

 grown like a common Cucumber or Melon. It 

 is of no use, and only worth cultivating as an 

 object of curiosity. 



Tricyrtis. From treis, three, and kurtos, convex ; 

 alluding to the three outer sepals having bags 

 at their bases. Linn. HemndrUi-Trigynia Nat. 

 Ord. Afelanthacece. 



TRI 



T. hirfa, 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 de- 

 sirable 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 is much used by the bouquet mak- 

 ers in the fall months. Propagated by division. 

 Introduced in 1855. 



Trifolium. Clover, Trefoil. From treis, three, 

 and folium, a leaf ; three-leaved. Linn. Diadd- 

 phia-Decandria. Nat. Ord. Fabacem. 



Of this very extensive genus there are several 

 species under cultivation as forage plants. They 

 include T. pratense, the common Red Clover, a 

 native of Great Britain; T. reflexum, Buffalo Clo- 

 ver, 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 in- 

 troduced from near Stockholm, Sweden. Be- 

 sides these there are a number of other species 

 that have been considerably cultivated, but those 

 named are almost wholly preferred for pasture 

 and hay. Those who are accustomed to consider 

 the Trefoil as only the common Clover of the 

 meadows, will probably be surprised to learn 

 that there are nearly a hundred and fifty spe- 

 cies, all more or less ornamental. Some of these 

 are perennials and some annuals; and the color 

 of their flowers varies from dark crimson, and 

 sometimes scarlet, to purple on the one hand, 

 and to white, cream-color, and pale yellow on 

 the other. Some of our dealers in hardy herba- 

 ceous plants have catalogued some of the more 

 showy species, and highly recommend them for 

 border plants. 



Trillium. From irttix, triple ; the parts of the 

 flowers in threes : the calyx has three sepals, 

 the corolla three petals, the pistil three styles, 

 and the stem three leaves. Linn. Hexandria- 

 Trigynia. Nat. Ord. TrUliacece. 



A singular and beautiful genus of hardy herba- 

 ceous plants, belonging exclusively to the United 

 States and the Canadas. The stems have three 

 leaves, and the flowers three petals. The flow- 

 ers are large, white, purple, or pink, produced 

 from April to June. They are common in moist 

 woods, but are improved with ordinary garden 

 cultivation. They are tuberous rooted, and do 

 not divide readily, but may be increased rapidly 

 from seed, which should be sown as soon as ripe 

 in a frame, where it may be shaded, or sown in 

 the open ground and slightly covered with leaves. 

 Triosteum. Feverwort, Horse Gentian. From 

 tre'is, three, and osieon, a bone ; three bony 

 seeds. Linn. Pentandria-Mbnogynia,. Nat. Ord. 

 Caprifoliacece. 



A genus of coarse-growing, hardy herbaceous 

 plants, common in the Middle and Southern 

 States. The roots of one of the species were es- 

 teemed by the Indians as a medicine. They 

 are not now considered either ornamental or 



Triteleia. From treis, three, and teleios, complete ; 

 parts of the flower and fruit in threes. Linn. 

 Hexandria-^^onogynia. Nat. Ord. LUiaccce. 



A small family of very pretty bulbs, natives of 

 California and South America. They are quite 

 hardy. The flowers are yellow, blue, and white.
