simple, the length of the stamina, club-shaped ; stigma bare, 

 innbonate. Pericarp: berry globular, two-celled, perforated 

 by two pores at top. Seeds : four, subovate, separated by 

 pulp. ESSENTIAL CHARACTER. Corolla: funnel-shaped; 

 throat naked. Stamina : in the tube. Stiyma: umbonate. 

 Berry: two-seeded, superior, perforated at top by pores. 

 The plants of this genus are propagated by seeds, which 

 must be procured from the countries where they grow natu- 

 rally. The seeds should be sown .in small pots rilled with 

 light earth, and plunged into a hot-bed of tanners' bark. They 

 sometimes grow within the first year, but oftener remain in the 

 ground a whole year; therefore if the plants should not come 

 up in the same season, the pots should be plunged in autumn 

 into the tan-bed in the stove, where they should remain all 

 t'he winter, and in the spring be removed out, and plunged into 

 a fresh tan-bed, which, if the seeds be good, will soon bring 

 up the plants. When they become fit to remove, plant each 

 in a small pot, plunging them into a tan-bed, where they 

 must be shaded from the sun till they have taken new root, 

 and must then be treated in the same way as other tender 

 plants from the same countries, which require to be con- 

 stantly kept in the bark-stove. They may also be increased 

 by cuttings. The species are, 



1. Tournefortia Serrata; Serrate-leaved Tournefortia. 

 Leaves ovate, serrate; petiole spinescent; spikes terminat- 

 ing, recurved. Native of South America. 



2. Tournefortia Hirsutissima; Hairy Tournefortia. Leaves 

 ovate, petioled, acuminate; stem hirsute; spikes branched, 

 terminating; berries hirsute; flowers white, directed all one 

 way. Browne says, that in the West India Islands, where 

 this plant is a native, it raises itself generally by the help of 

 the neighbouring trees, and shoots sometimes to a consider- 

 able height in the woods. 



3. Tournefortia Volubilis; Climbing Tournefortia. Leaves 

 ovate, acute, deflexed, rough with minute points; petioles re- 

 flexed ; stem twining. The flowers are produced in branching 

 spikes from the side and top of the branches; they are small and 

 white; and are succeeded by small, white, succulent berries, 

 having one or two black spots on each; seed one in each cell. 

 It flowers in July and August. Native of Jamaica. 



4. Tournefortia Syrengsefolia ; Lilac -leave d Tournefortia. 

 Leaves subcordate, ovate, acuminate, smooth ; spikes branch- 

 ed; branches petioled; midrib of the leaves on both sides, 

 and the nerves beneath, and peduncles, villose ; flowers 

 alternate, approximating ; corollas somewhat villose on the 

 outside. Found in Cayenne. 



5. Tournefortia Foetid issitna; Fetid Tournefortia. Leaves 

 ovate, lanceolate, rough-haired ; peduncles branched ; spikes 

 pendulous. Stems shrubby, ten or twelve feet high, sending 

 out many branches, which are terminated by long branching 

 spikes of flowers, ranged on one side like those of the Helio- 

 trope. The flowers are of a dirty white colour, small, and 

 closely set. Native of the West Indies. 



6. Tournefortia Humilis; Dwarf Tonrncfortia. Leaves 

 lanceolate, sessile; spikes simple, recurved, lateral. Stalks 

 low, shrubby, seldom rising more than three feet high, send- 

 ing out a few slender woody branches. The flowers come out 

 in single axillary spikes; they are white, and are succeeded 

 by small succulent berries. Native of South America. 



7. Tournefortia Bicolor ; Two-coloured Tovrncforlia. 

 Leaves ovate, acuminate, smooth, somewhat wrinkled above; 

 spikes cymed, erect, recurved. Trunk round, branched, 

 even ; branches hirsute, alternate, almost upright, round, 

 smooth ; corollas greenish-white, with an hoary tube. 

 Native of Jamaica, in coppices. 



8. Tournefortia Cymosa; Broad-leaved Tournefortia. 



Leaves ovate, quite entire, naked; spikes cymed; stem a 

 fathom in height. Native of Jamaica ; where, Browne in- 

 forms us, it is sometimes observed in the woods, and remark- 

 able for the thickness of its upper branches, and the length 

 oi' its pendulous flower-spikes. It flowers in July. 



9. Tournefortia Argentea; Silvery Tournefortia. Leaves 

 ovate, obtuse, tomentose, silky; spikes terminating, com- 

 pound. Truny-* very short, covered with a deeply cloven 

 bark ; branches'spreading, very much hirsute ; panicle large, 

 divided into spikes, directed one way, and rolled back ; 

 flowers snow-white ; tube short ; border recurved ; berries 

 not perforated. It is the handsomest species of the genus. 

 Native of the shores of Ceylon, &c. 



10. Tournefortia Sericea; Silky Tournefortia. Leaves 

 ovate, lanceolate, beneath tomentose, silky; spikes lateral 

 and terminating, dichotomous, paniclcd. This has the ap- 

 pearance, of the third species ; flowers small, distinct, alter- 

 nate. -Found by Ryan in Montserrat. 



11. Tournefortia Suffruticosa ; Hoary-leaved Tournefortia. 

 Leaves snblanceolate, hoary ; stem suffruticose. Branches 

 slender, woody; flowers terminating and axillary, in slender 

 branching spikes, which are recurved; they are white, and 

 succeeded by small succulent berries, which contain two or 

 three seeds. Native of Jamaica, by the sea-side. 



12. Tournefortia Scandens ; Climbing Tournefortia. 

 Leaves cordate, hirsute; spikes racemed, reflexed ; stem 

 twining, shrubby, branching, rising to the height of ten or 

 twelve feet; the flowers come out at the ends of the 

 branches, in very slender branching spikes; they are small, 

 and of a dirty brown colour. Found in Jamaica. 



13. Tournefortia Tomentosa; Downy Tournefortia. Leaves 

 cordate, tomentose beneath; spikes racemed, short; stem
