bark, shading them from the sun until they have taken new 

 root ; they then may have free air every day admitted to 

 them, in proportion to the warmth of the season, and must 

 neither be drawn up weak, nor should they have too much 

 water. In the autumn the plants must be removed into the 

 stove, where they should have a temperate warmth in winter, 

 but during that season little water should be given them, 

 nor should they have too much heat ; for either of these will 

 soon destroy them. As the plants obtain strength they will 

 become hardier, and may be set in the open air for two or 

 three months in the heat of summer, but should always be 

 placed in a sheltered situation ; in winter they must be placed 

 ia a stove, kept to a moderate temperature of warmth, for 

 the plants will not live in a green-house here. This plant 

 was formerly shewn for the Tea-tree, in many parts of the 

 European gardens ; and passed for it during many years, 

 among those who knew no better. 



2.Dodonsea Angustifolia ; Narrow-leaved Dodoncea. Leaves 

 linear. It resembles the foregoing : the fructification is po- 

 lygamous. It flowers from May to August ; and is a native 

 of the Cape of Good Hope. The second sort is less tender 

 than the first, and requires only the protection of a green- 

 house or glass-case.

Dolicluis; a genus of the class Diadelphia, order Decan- 

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

 very short, four-toothed, equal ; the superior tooth emar- 

 ginate. Corolla : papilionaceous ; standard roundish, large, 

 emarginate, the whole reflex ; two calluses oblong, parallel 

 and longitudinal, growing to the standard beneath towards 

 the base, compressing the wings, not hollowed on the back ; 

 wings ovate, obtuse, length of the keel ; keel lunulate, com- 

 pressed, beneath converging closely, length or the wings, 

 ascending at the tip. Stamina : filamenta diadelphous, simple 

 and nine-cleft, the simple one curved at the base ; antherse 

 simple. Pistil : germen linear, compressed ; style ascend- 

 ing ; stigma bearded, running on inwardly from the middle 

 to the tip of the style, which on the fore part is callous, ob- 

 tuse. Pericarp : legume acuminate, large, oblong, two- 

 valved, two-celled. Seeds : several, elliptic, usually com- 

 pressed. ESSENTIAL, CHARACTER. Two parallel oblong 

 calluses at the base of the standard, compressing the wings 

 underneath. Most of these species come from the East and 

 West Indies, are tender, and seldom perfect their seeds in 

 England ; they are principally annual plants, and are fre- 

 quently lost in our stoves. Several species are cultivated for 

 the table in warm countries, but seldom perfect their seeds in 

 England ; and were they to thrive here as well as in the warm 

 countries, they would be little esteemed, because we already 

 have much better sorts in our gardens; for the scarlet-flower- 

 ing kidney-bean is preferable to all of them for eating, and 

 deserves to be cultivated more than any other. The spe- 

 cies are, 



* Twining. 



1. Dolichos Benghalensis. Shrubby ; legumes ending in 

 long dagger-points. This is perennial ; the stem is rather 

 roughish to the touch, and scandent, as well as producing 

 several branches ; leaves roundish, ovate, ending in a point, 

 furnished with a bristle ; stipules lanceolate ; peduncles ra- 

 cemose, four or five inches long; flowers seated on very short 

 peduncles, uncertain as to number, snow-white, and slightly

odorous; legume oblong, pointed, compressed, first green, 

 afterwards growing pale ; seeds few, roundish-oblong, com- 

 pressed, brown, with deeper-coloured points, and with along 

 protuberant, snow-white hilum. 



2. Dolichos Lablab ; Black-seeded Dolichon. Legumes 

 ovate, salver-shaped; seeds ovate, with a bowed eye towards 

 one end. Stems and branches round, scabrous backwards ; 

 peduncles forming half whorls ; seeds three or five, flatted a 

 little, smooth, but not shining, black or ferruginous, edged 

 on one side with a fungous snow-white callous, proceeding 

 from the umbilicus, they have no albumen. Alpinus says, 

 that this plant grows wild in Egypt : Hasselquist, however, is 

 certain it does not grow wild in Lower Egypt, but is only 

 cultivated there in gardens. The Egyptians call hful Frangi, 

 or European bean ; and thence we may conjecture that the 

 Europeans first brought it into Egypt. The natives make 

 pleasant arbours of it, notonly supporting it with trellis work, 

 but fastening it with twine, by which means the leaves form 

 an excellent covering and an agreeable shade. 



3. Dolichos Sinensis ; Chinese Dolichos. Legumes pendu- 

 lous, cylindric, torulose ; peduncles erect, many-flowered. 

 Stem annual, long, round, slender,twining,somewhat branch- 

 ed ; leaves ternate, broad-lanceolate, smooth, with two or 

 three lanceolate stipules at the base of the common petiole ; 

 flowers pale violet,on few-flowered, suberect, axillary pedun- 

 cles ; standard ascending, very blunt. Native of Amboyna, 

 China, Cochin-china, and the East Indies generally. 



4. Dolichos Uncinatus ; Hook-podded Dolichos. Legumes 

 cylindric, hirsute, with a hooked sububite claw at the end ; 

 peduncles many-flowered ; stem rough with hairs. Native 

 of Jamaica. 



5. Dolichos Luteolus. Legumes in several cylindric heads ; 

 seeds rounded. Stem rather angular, branched, round. A 

 sc'andent plant ; branches three or four cubits long; leaves 

 ovate, entire, subacute, glossy; stipules small, and roundish ; 

 peduncles axillary, supporting from six to ten elegant yellow 

 flowers ; the stigma bearded. Native of the Society Isles. 



6. Dolichos Unguiculatus ; Bird's-foot Dolichos. Legu- 

 mes in subcylindric heads, recurved, and concave at the 

 tip. This is an annual smooth plant, with a climbing stem ; 

 leaves lanced-ovate, and sharp ; peduncles upright, sup- 

 porting but few flowers ; flowers whitish ; stigma long and 

 bearded ; seed whitish, with a snow-white hilum. Native 

 of the West Indies. Loureiro says it is a native of Chinay 

 and was imported into Portugal. 



7- Dolichos Tranquebaricus. Legumes few, in cylindric 

 heads, with a straight dagger-point. The whole plant is very 

 smooth ; the vexillum, or standard of the flowers, pale yellow- 

 behind, and blush red in front, the wings more blue, and 

 the keel white. 



8. Dolichos Enslformis ; Horse Bean. Legumes gladiated, 

 three-keeled at the back ; seeds arilled. Stem three or four 

 feet high, with shoots running much farther; the legumes are 

 between ten and fourteen inches in length, and generally 

 contain ten or eleven seeds. This species is distinguished 

 by its large falcated legume and white seeds, with a saffron- 

 coloured scar. Native of Jamaica. 



9. Dolichos Tetragonolobus. Legumes quadrangular- 

 membranaceous. Stem herbaceous, round, slender, scandent, 

 long, branching; leaflets broad-lanceolate, smooth, pale 

 green ; stipules lanceolate, minute ; flowers pale blue, on 

 long, lateral, flew-flowered peduncles ; seeds about eight. 

 Native of the East Indies, China, and Cochin-china. 



10. Dolichos Sesquipedalis ; Long-podded Dnlichos. Le- 

 gume subcylindric, even, very long; standard of the flower 

 pale above, reddish within ; legume more than a foo; and a
