 throat, converging, acuminate: the pistillum 

 is a giolMilar sujierior germ : style simple, length 

 of the stamens, club-shaped : stigma circum- 

 cised, entire : the pericarpium is a globular

The species cultivated are: 1. T. hirsvtissbna, 

 Hairy Tournefortia ; 2. T. I'ohd'i/is, Climbing 

 Tonrnefortia ; 3. T.fceluUssbna, Fetid Tourne- 

 fortia ; 4. T. humilis, Dwarf Tournefortia ; 5. 

 T. ajmosa, Broad-leaved Tournefortia; 6. T. 

 argentea, Silvery Tournefortia; 7« T, suffniti- 

 cosa. Hoary-leaved Tournefortia. 



The first has a shrubby stem, somewhat scan- 

 dent, branched, covered with a ferruginous 

 shagginess : the leaves oblong, entire, nerved, 

 hairy all over, but extremely so beneath : the 

 spikes or racemes very much branched, stiff and 

 straight, spreading a little: the flowers white, 

 directed all one way. It is a native of the islands 

 in the West Indies. 



The second species has a twining woody stalk, 

 which twists about the neighbouring trees for 

 support, and rises to the height of ten or twelve ' 

 feet, sending out several slender woody branches: 

 the flowers are produced in branching spikes 

 from the side and top of the branches; are small 

 and white, and succeeded by small white suc- 

 culent berries, having one or two black spots on 

 each. It is a native of Jamaica, flowering in 

 July and August. 



The third has shrubby stems, ten or twelve 

 feet high, sending out many branches : the 

 leaves alternate, five inches long, two inches 

 and a half broad in the niiddle, hairy on their 

 under side, standing upon short foot-stalks : 

 the branches are terminated by long branching 

 spikes of flowers, ranged on one side ; some of 

 the foot-stalks sustain two, others three, others 

 again four spikes of flowers, near five inches in 

 length, reflexed at the top: the flowers are of a 

 dirty white colour, small, and closely set ; they 

 are succeeded by small succulent fruit. It is a 

 native of Jamaica. 



The fourth species has low shrubby stalks, 

 which seldom rise more than three feet high, 

 sending out a few slender woody branches : the 

 leaves are rough, dark green on their upper, but 

 pale on their under surface : the flowers come 

 out in single axillary spikes ; are white, and 

 succeeded by small succulent berries. It is a 

 native of South America. 



The fifth has the stem a fathom in height : the 

 branches herbaceous, angular, grooved, smooth : 

 the leaves ovate-lanceolate, long, petioled, 

 smooth, wrinkled beneath : the flowers sessile.

on one side, disposed in two rows. It is a na- 

 tive of Jamaica, flowering in July. 



The sixth S])ecies is a shrub, scarcely the 

 heiglit of a man : the trunk is very short, co- 

 vered with a deeply cloven bark : the branches 

 spreading very much, hirsute: the leaves at the 

 ends of the branches, alternate, approximating 

 into a rose as in Sempcrvivum Canariense, ovate 

 or tongue-shaped, (being narrowed into the 

 petiole,) sessile, rounded at the end, white all 

 over, with a silky hairiness pressed close to 

 them : the panicle large, divided into spikes, 

 directed one way, and rolled back: the flowers 

 snow-white. It is a native of the shores of the 

 sea of Ceylon, &c. 



The seventh has woody stalks which rise five 

 or six feet high, from which spring out many 

 slender woody branches : the leaves about two 

 inches long, and an inch broad in the middle, 

 rounded at each end with acute points; of a dark 

 green on their upper surface, but having a white 

 down on their under side, and sitting close to 

 the branches : the flowers terminating and axil- 

 lary, in slender branching spikes, which are re- 

 curved ; and the flowers ranged on one side of 

 them, white, and succeeded by small succulent 

 berries. It is a native of Jamaica. 



Culiure. — These plants may all be increased 

 by seeds, which should be procured from the 

 countries where they grow naturally, and sown 

 in small pots filled with light earth, and plunged 

 into a hot-bed of tanners bark. They some- 

 times grow the first year, but often remain in 

 the ground a whole year : therefore, when the 

 plants do not come up the same season, the pots 

 should be plunged in autumn into a tan-bed in 

 the stove, where they should remain all the 

 winter, and in the spring be removed and 

 plunged into a fresh tan-bed, which will soon 

 bring up the plants if the seeds were good. 

 When these are fit to remove, they should be 

 each planted in a small pot, and plunged into a 

 tan-bed, where they must be shaded from the 

 sun till they have taken new root, and then be 

 treated in the same way as other tender plants 

 from the same countries, which require to be 

 kept constantly in the bark-stove. They may also 

 sometimes be increased by cuttings, which should 

 be planted in pots and plunged into the bark-bed. 



They afford variety in stove collections.
