 nogynia. GENERIC CHARACTER. Calix: perianth five- 

 leaved ; leaflets lanceolate, arilled below the tip, deciduous.

 backward just above the base. Stamina : filamenta sixteen, 

 equal, ascending, length of the corolla, awl-shaped, erect; 

 antherse simple. Pistil: germeu roundish ; style length of 

 the stamina; stigma bifid, acute. Pericarp: capsule globu- 

 lar, fenced on every side with hooked prickles, four-celled. 

 Seeds: one or two in each cell, convex on one side, angular 

 ontheother. ESSENTIAL CHARACTER. Cafe: five-leaved. 

 Corolla: five-petalled. Capsule: hispid, opening in four parts. 

 The species are, 



1 . Triumfetta Lappula ; Prickly-seeded Triumfetta. Leaves 

 emarginate at the base; flowers in densely whorled aggregate 

 spikes. Stem upright, six or seven feet high, becoming woody, 

 and dividing at top into four or five branches. The branches 

 are terminated by long spikes of flowers, which come out in 

 clusters from the side of the principal footstalk, at the dis- 

 tances of about an inch. The flowers are small, the petals 

 narrow, and of a yellow colour; and are succeeded by burry 

 capsules somewhat like those of Agrimony, but round, ani 

 with longer prickles placed on every side. It flowers in July 

 and August, and in warm seasons the seeds sometimes ripen 

 in England. Native of Jamaica, Martinico. and other 

 islands of the West Indies, the Bermudas, and Brazil. Sow 

 the seeds on a hot-bed early in the spring; when the plants 

 come up, transplant each into a separate pot, filled with light

fresh kitchen-garden earth, and plunge them into a moderate 

 hot-bed of tanners' bark, shading them from the sun until 

 they have taken new root, and then treating them in the 

 same manner as other tender exotic plants. In autumn re- 

 move them into the bark-stove, and refresh them with water 

 frequently, except in very cold weather, If they survive the 

 winter, they will flower in the summer following, and ripen 

 their seeds in autumn, and may be continued two or three 

 years, if carefully managed. 



2. Triumfetta Glandulosa; Glandular Triumfetta. Leaves 

 ovate-lanceolate, tomentose, hoary beneath; flowers axillary, 

 from the upper leaves ; branches woody, round, villose. It 

 differs from the fourth species in having the leaves only half 

 the width, not angular towards the outside, acute, not acumi- 

 nate, with the hairs beneath more distinct, and the stipules 

 setaceous, subulate. Native of Arabia Felix and India. 



3. Triumfetta Bartramia; Currant-leaved Triumfetta. 

 Leaves entire at the base, undivided ; flowers racemose, 

 partly aggregate, the lower ones axillary. Root annual ; 

 flowers small, purple, or rose-coloured ; capsule spherical, 

 white, tomentose, echinated, with bristle-shaped, hooked, 

 smooth little prickles, four-grained, quadripartile; grains 

 coriaceous, convex on one side, angular on the other, two- 

 celled, valveless, growing to the seeds; seeds solitary, two 

 in each grain, and eight in the whole, from an ovate drawn 

 to a point upwards, convex on one side, angular on the 

 other, rufescent. Sometimes the capsules are only three- 

 grained, and tripartile ; others may easily be divided into six 

 or eight parts, each seed being covered with its proper cell, 

 as in Marracese. Native of the East Indies. 



4. Triumfetta Velutina ; Velvet Triumfetta. Leaves ovate, 

 somewhat angular, acuminate, tomentose, hoary beneath ; 

 stem erect, softly villose, round ; stipules lanceolate, attenu- 

 ated, ciliate, ferruginous ; flowers from the bosoms of the 

 upper leaves. Native of the Isle of France. 



5. Triumfetta Procumbens; Procumbent Triumfetta. Leaves 

 roundish-cordate, subtrilobate, tomentose ; stem procumbent. 

 Native of the Society Isles. 



6. Triumfetta Hirta; Hairy Triumfetta. Leaves three- 

 lobed, acute; smooth above; panicle terminal, dichotomous, 

 rough-haired ; stem frutescent. Native of the island of Santa 

 Martha in America. 



7. Triumfetta Semitriloba; Mallow-leaved Triumfetta. 

 Leaves half three-lobed; panicle terminal, compound, downy. 

 This is an upright branching shrub, six feet high, and is so 

 like the first species in its habit, that at first sight they might 

 be easily mistaken. The flowers are yellow, not many toge- 

 ther. The leaves and tender buds infused in water, yield a 

 fine cle-ar mucilage ; from which the plant is thought to be a 

 good emollient. The bark is tough and strong, and serves 

 for ropes, and other things of that kind, in the West Indies, 

 where it is a native, and flowers in July. 



8. Triumfetta Grandiflora; Great-flowered Triumfetta. 

 Leaves subcordate-ovate, entire, serrate, somewhat hairy; 

 floral leaves lanceolate ; branches rough-haired. Stem 

 woody, round, with the branches smooth below, rough-hair- 

 ed above, bifid at the end. It differs from the other species 

 in having the corollas twice or thrice as large ; stipules lan- 

 ceolate, acuminate. Native of Montserrat. 



9. Triumfetta Macrophylla; Long-leaved Triumfetta. 

 Leaves ovate-cordate, entire, unequally serrate, acuminate, 

 tomentose, glandular at the base ; branches round and 

 tomentose, as is the whole plant. It resembles the first 

 species ; and may be distinguished from the next by the 

 form and tomentoseness of the leaves. Native of South 

 America.
