Triguera; a genus of the class Pentandria, order Mono- 

 gynia. GENERIC CHARACTER. Calix: perianth one-leafed, 

 half five-cleft, permanent; segments unequal, acute. Corolla: 

 one-petalled, bell-shaped; tube very short; border ventri- 

 cose, plaited, five-cleft, longer than the calix, the two upper 

 segments reflexed; nectary membranaceous, short, five- 

 toothed, surrounding the germen. Stamina: filamenta five, 

 very short, inserted outwardly into the teeth of the nectary ; 

 antiiertE sagittate, converging. Pistil: germen roundish, 

 two-grooved ; style filiform, straight, a little longer than the 

 stamina; stigma obtuse. Pericarp: a dry berry, subglobu- 

 Inr, grooved, four-celled. Seeds: two in each cell, roundish, 

 compressed, rugged, one above another. ESSENTIAL CHA- 

 RACTF.R. Corolla: bell-shaped, with an unequal border. 

 Nectary: short, five toothed, surrounding the germen. Fila- 

 menta: inserted into the nectary. Berry: four-celled, with 

 two seeds in each cell. The species are, 



1. Triguera Ambrosiaca. Stem grooved and winged ; tipper 

 leaves obovate, toothed, pubescent; peduncles axillary, in 

 pairs : corolla resembling that of the Henbane, of a violet 

 colour: annual. This is said to possess the emollient nar- 

 cotic virtues of Deadly Nightshade and Hemlock, being, like 

 them, useful incancers. Native of Spain, found in Andalusia. 



2. Triguera Inodora. Leaves ovate-lanceolate, quite entire, 

 smooth. This is scarcely winged, the leaves a little, or not 

 at all, running down the stalk : annual. Native of Spain, 

 found iu Andalusia. 



Trilix; a genus of the class Polyandria, order Monogynia. 

 GENERIC CHARACTER. Calix: perianth three-leaved; 

 leaflets ovate, acme, spreading, flat, permanent. Corolla : 

 petals three, lanceolate, acute, less than the calix. Stamina : 

 filamenta numerous, capillary, length of the corolla ; antherse 

 roundish, twin, minute. Pistil: germen five-cornered; style 

 cylindrical ; stigma simple. Pericarp : berry subpentagonal, 

 five-celled, covered with the calix. Seeds: numerous, round- 

 ish, minute. ESSENTIAL CHARACTER. Calix: three-leaved. 

 Corolla : three-petalled. Berry : five-celled, many-seeded. 

 The only known species is, 



1. Trilix Lutea. A shrub two fathoms high, with very 

 numerous, round, roughish branches ; leaves alternate, peti- 

 oled, subpeltate, cordate, ovate, serrate, acuminate, veined, 

 pubescent; petioles round, smooth; flowers yellow, not from 

 the corolla but the antherae. Native of Carthagena. 



Trillium; a genus of the class Hexandria, order Trigynia. 

 GENERIC CHARACTER. Calix: perianth three-leaved, 

 spreading; leaflets ovate, permanent. Corolla: petals three, 

 subovate, a little bigger than the calix. Stamina: filamenta 

 six, awl-shaped, shorter than the calix, erect; antherse ter- 

 minating, oblong, length of the filamenta. Pistil: germen 

 roundish ; styles three, filiform, recurved ; stigmas simple. 

 Pericarp: berry roundish, three-celled. Seeds: many, round- 

 ish. ESSENTIAL CHARACTER. Calix: three-leaved. Co- 

 rolla: three-petalled. Berry: three-celled. These plants 

 all grow in shady situations and a light soil, and require 

 the same treatment as Dodecatheon, and Round-leaved 

 Cyclamen. They continue to be rare plants in this country, 

 because they require much attention in their culture, admit 

 of little increase from their roots, and can only be raised from 

 seeds by a tedious process. Sow the seeds upon a shady 

 border soon after they are ripe, and then the young plants 

 will come up in the next spring, but if the seeds be sown in 

 the spring, they will remain in the ground a year. When 

 the plants appear, keep them clean, and in autumn, after 

 their leaves decay, transplant the roots to a moist shady place, 

 where they are to remain. The species are, 



1. Trillium Cernuum; Drooping Trillium. Flowers pedun- 

 cled, drooping; petals lanceolate, acuminate; leaves dilated. 

 Root perennial, tuberous ; stem erect, a foot high, simple, 

 round, slightly striated, smooth ; leaves three together, ter- 

 minating, on short footstalks, spreading, rhomboidal, pointed, 

 entire, smooth, veiny, paler beneath ; flower-stalk round, a 

 little waved, smooth ; petals the length and figure of the 

 calix, whitish, marked with bluish lines, reflexed. The 

 flowers appear in April, and the berries ripen in June. 

 Native of woods in many parts of North America. 



2. Trillium Erectum ; Upright Trillium. Flower pedun- 

 cled, erect. This has a taller stalk than the preceding: the 

 three leaves are placed at a distance from the flower, which 

 stands upon a long footstalk, and is erect; the petals are 

 white, or deep purple, longer, and end with sharper points. 

 Native of Virginia, Canada, and other parts of N. America. 



3. Trillium Sessile ; Sessile-flowered Trillium. Flower 

 sessile, erect. Stalk purple : the three leaves grow at the 

 top like the first, but they are much longer, and end in acute 

 points ; the petals are long, narrow, and stand erect, they 

 are of a dark brownish-red, nearly the same colour as the 

 Carolina Allspice. Native of Carolina and Virginia. 



4. Trillium Petiolatum. Flowers sessile, erect; petals 

 linear-lanceolate, erect, a little longer than the calix ; leaves 

 petiolated at great length, oval-lanceolate, acute. Grows 

 near the sources of the Columbia. This singular species, 

 whose flowers resemble those of the preceding species, has 

 leaves very much like Plantago Major.
