sible, without being shaded by other plants ; 

 which induces mouldiness. These, like the an- 

 nual sons, require to be removed two or three 

 times in the summer into other p6ts, to prevent 

 their shooting their roots through the holes, and 

 being injured when taken up. 



From their being easily destroyed in the win- 

 ter, it is necessary to raise supplies annually 

 from cuttings in the summer season. 



And as many of the plants rise to the height of 

 three or four feet or more, and send forth many 

 branches, they require occasional pruning. 



As they flower both in the summer and winter 

 seasons, they are curious, and afford a pleasing 

 variety in the green-house or stove. 



ARDUINA, a genus comprising a plant of 

 the evergreen shrubby kind for the green-house. 

 The Cape Buckthorn. 



It belongs to the class and order Penlandria 

 Monogynia, and ranks in the natural order of 

 Contortce. 



The characters of which are : that the calyx 

 is a five parted, erect, acute, small, permanent 

 perianthium : the corolla one-petalled, funnel- 

 shaped : the tube cylindrical, a little curved in- 

 wards at top : the border fire-parted, acute and 

 spreading : the stamina consist of five simple 

 filaments, shorter than the tube, and inserted 

 into the lower part of it : the antherae are oblong, 

 within the throat of the corolla : the pistillum 

 is a germ superior and ovate : the style filiform, 

 the length of the tube, and the stigma bifid, 

 thickish : the pericarpium is a globular-oval, two- 

 celled berry : the seeds solitary, oblong and 

 hard. 



There is only one species, A. lispinosa, 

 Two-spined Arduina. 



It is alow shrubby plant, seldom rising above 

 four or five feet in height. It sends out spread- 

 ing branches in pairs from top to bottom, and 

 they are covered with a dark -green bark, and 

 armed with short strong thorns, which come 

 out by pairs 5 and sometimes there ate double 

 pairs upon the same foot-stalks, which are situa- 

 ted just below the leaves ; and where there are 

 four, two point upwards, and the other two 

 downwards. The leaves are heart-shaped, not 

 much larger than those of the Box Tree, or 

 about an inch long, and three-quarters of an 

 inch broad at their base, of the same consist- 

 ence and colour, terminating in acute points; 

 they are placed opposite in pairs pretty close to- 

 gether, and continue green all the year. The 

 flowers come out in clusters at the ends of the 

 branches, upon short slender peduncles, each 

 supporting five or six small white flowers, having 

 an agreeable odour. They commonly appear in 

 July and August, and are seldom succeeded bv 

 0' 



seeds in this climate. The berries do not ripen 

 till the following spring, and are then of a deep- 

 red colour. It is a native of the Cape of Good 

 Hope. 



Culture. — This plant is capable of being in- 

 creased by cuttings and layers of the young shoots, 

 the' former planted out in the summer season in 

 pots, plunged in moderate hot-beds, and shaded 

 from the sun. After they have taken root', they 

 should be removed into small pots, and placed in 

 the shade till they have taken fresh root : they 

 may then be removed to a sheltered situation till 

 autumn, when they must be put into a green- 

 house, or under a hot-bed frame, as they are too 

 tender to live in the open air. 



This is an elegant plant ; but requires to be 

 constantly kept in pots, in order to be removed 

 into the shelter of the green-house during se- 

 vere weather. 



ARECA, a genus comprising a tree of the 

 exotic Palm kind. The Fausel-nut Palm, or 

 Cabbage Tree. 



It belongs to the class and order Moncecia 

 Emieandria, and ranks in the natural order of 

 T?almce. 



The characters are : that in the male flowers 

 the calyx is a bivalve spathe, having the spadix 

 branched : proper perianthium three-leaved : the 

 corolla consists of three acuminate, rigid pe- 

 tals : the stamina consist of nine filaments, the 

 three outer longer than the rest : female flowers 

 in the same spadix : the calyx is a common spathe 

 with the males : proper perianthium three-leaved : 

 the corolla three acuminate rigid petals : the 

 pericarpium a subovate, fibrose berry, surrounded 

 at the base with the imbricate calyx : the seed 

 is ovate. 



The species is A. oleracca, or Cabbage 

 Tree. 



In this the sheaths of the leaves are very 

 close, and form the green top of the trunk, a 

 foot and half in length. Below this come out 

 green shining spathes, which fall to the ground 

 when the very branching spadix bursts forth. 

 The calyx of the flower is one-leafed, cut half 

 way into three segments. The fruits are ob- 

 long, obtuse berries, slightly bent, of a blue 

 purple colour, succulent, scarcely fibrose, the 

 size of a middling olive : the pulp dries away, 

 and becomes a brittle, wrinkled bark. The nut 

 or stone is oblong, smoothish, rather acute at 

 the base, membranaceous, brittle, thin, whitish- 

 brown frequently with a shade of red. The ker- 

 nel is oblong, cartilaginous, very hard, and has 

 a cavity in the middle of a small fissure. In its 

 native state the inhabitants cut off the green top 

 of the trunk, take out the white heart, and 

 make use of it as an article of food. But in
