tube : the corolla has five petals, obcordatc, 

 aciirtiinate, flat, from upright spreading : claws 

 narrow, inserted into the tube of the calyx : the 

 stamina have five awl-shaped filaineiits, shorter 

 than the corolla, inserted into ihe tube of the 

 calyx: anthers acuminate, erect: the pistiikmi 

 is a conical germ : styles three: fihform, length 

 of the stamens : stigmas capillaceous-multifid : 

 the pericarpium is an ovate capsule, one-celled, 

 three-valved : receptacles anne.\ed,to the valves 

 lono;itudiiially, linear : the seeds numerous, ob- 

 long, obtuse. ♦ 



The species cultivated is T. ulmifolia. Elm- 

 leaved ''\irnera. 



It has a shrubby stem, eight or ten feet high, 

 sending out branches on every side the whole 

 length : the leaves ovate-lanceolate, two inches 

 and a half long, and an inch and half broad, 

 rough on their upper side, and of a lucid green; 

 their under side has many strong veins, and is 

 of a lighter green, the edges are serrate: the 

 flowers sit close upon the footstalks of the 

 leaves, having two pretty large leafy appen- 

 dages to the calyx: the croHa Is large, and of 

 a bright yellow. It is a naiive of the West 

 Indies. 



There is a variety with narrow leaves, which 

 •rises with a shrubby stalk to the height of eight 

 or ten feet, with branches less slender and stiff 



than in (he broad -leaved sort : the leaves narrow- 

 lanceolate, hairy, near three inches long, and 

 about three quarters of an inch broad, tenuina- 

 ting in acute points, obtusely serrate on their 

 edges, and standing upon very short footstalks; 

 when rubbed, they emit a disasreeable odour : 

 the flowers are of a pale yellow :^the petals larn-e 

 and oval, with the tails or claws twisted and 

 joining: they are not so large or of so bright a 

 yellow as in the true Elm-leaved sort. It is a 

 native of Jamaica. 



Culture. — These plants are easily raised from' 

 seed, which should be sown in the sprinsi, in 

 pots, and plunged in the bark-bed, or any other 

 hot-bed, under glasses; and when the plants 

 are come vip two or three inches in height, they 

 should be planted separately in sm°all pots, 

 plunging them in the stove of the bark-bed, to 

 forward them a little in growth: they may af- 

 terwards be placed in any part of the stove, and 

 be managed as other stove exotic plants. They 

 are also capable of being increased by cuttings, 

 planted in |)ots, and forwarded in the abcTvc 

 manner. They aflbrd a good variety among 

 stove plants.

 PapiUo/n/cecE or Legumhiosa; . 



The characters are : that the calyx is a two-

 than the keel : upper leaflet two-toothed, lower 

 three-toothed : the corolla papilionaceous, five- 

 petalled : standard obeordate, emarginate, erect, 

 very large : wings oblong, obtuse, shorter than 

 the standard : keel two-petalled, straight, ob- 

 tuse, converging by the lower margm : the 

 stamina have diadelphous filaments, sim))!e and 

 nine-cleft: anthers simple: the pislillum is an 

 oblong germ, cylindrical, hirsute: style fdi- 

 form, rising: stigma obtuse, very small: 

 the pericarpium is an oblong legume, turgid, 

 scarcely longer than the calyx, straight, one-

celled, two-valved: the seeds few, roundish, 

 emarginate. 



The species cultivated are : 1 . U. Enropceus, 

 Common Furze, Whin, or Gorse ; 2. U. 7iaiius, 

 Dwarf Furze; 3. U. Capaisis, Cape or African 

 Furze. 



The first is a well known shrub, which has 

 its branches very close, deeply furrowed, wool- 

 ly or hirsute, full of thorns, which are stretched 

 out, branched, angular, very sharp, smooth, 

 evergreen, leafy, frequently flower - bearing '; 

 according to Withering, awl-shaped, a little 

 bowed downwards, woolly at the base, yellow 

 at the ends : the leaves at the base of the spines 

 and spinules, solitary, awl-shaped, terminating 

 in sharp yellowish thorny points, somewhat 

 rugged, often hirsute, deciduous: the peduncles 

 axillary, single or two together, one-flowered,
