NATURAL ARRANGEMENT.

ened embryo, and stipulate leaves, the vernation of which Is involutive, not circinate. From Passlflorera they 

 differ in their fruit being capsular, not berried ; in their albumen being compact and shining, not pitted ; in 

 their stamens being hypogynous, not perigynous ; in their anthers being attached along their whole length, not 

 fixed by their middle ; finally, in their stigmas being one and not three. The genus Calyptrion approaches 

 Passifloreee in its twining stem, and Hymenanthera borders upon Polygaleaj on account of its monospermous 

 pericarpium with solitary pendulous seeds. Divisions, seeds, and cuttings.

 The order of sun-dews is a small group of plants, natives of marshes or inundated grounds in all the tem- 

 perate parts of the world. The species are very remarkable for the abundance of glandular hairs with which 

 all the parts of the foliage are covered. Only two species are in any degree frutescent. The young leaves are 

 always rolled up in the circinate manner, so remarkable in ferns. Their medicinal properties appear to be 

 trifling : the leaves have the power of curdling milk. Divisions or seeds, some by leaves.

 Most of the plants of this order are interesting, and deserving the attention of the gardener some for their 

 neatness, some for their beauty, and some for their use in medicine. They are natives of most countries and 

 are either low herbaceous plants, occasionally less than an inch in height (small specimens of Polygala'pur- 

 purea), or shrubs varying from a dwarf, rigid, spiny habit, to a tall, graceful, drooping appearance. Polygalea? 

 are remarkable for the union of their stamens into a single body, their one-celled anthers opening with a pore 

 and their irregular flowers, one of which is often keel-shaped, and beautifully crested or bearded. The leaves 

 have generally a bitter astringent taste, which is much more abundant in the roots, combined with an acrid 

 and somewhat resinous flavor : these properties are particularly sensible in P. Senega, which is reputed a 

 sudorific, diuretic, sialagogue, cathartic, or mild emetic, according to the manner in which it is administered. 

 The Yelhoi of South America, the root of a species of Monnina, has the same properties as P. Senega and is 

 particularly used as a remedy for dysentery. The well known Rattany, or Ratanhia root, of Chile,' is the 

 produce of a plant of this order, and possesses powerful tonic and astringent qualities. According to the 

 analysis of a French chemist, it contains gallic acid, but neither tannin nor resin. Cuttings or seeds.

 A very small order, containing only seven species, all small bushes, natives of New Holland, and remarkable 

 for the peculiar neatness of their appearance. In habit, they may be compared to heaths, with which they 

 agree in the anthers bursting by a pore at the end. Nothing is known of their properties. Cuttings or seeds.

 Beautiful shrubs and small trees, with simple alternate leaves destitute of stipulas, and white or yellow 

 flowers, chiefly natives of New Holland and the African islands. The order is distinguished by the imbricate 

 aestivation of the sepals and petals, which last, as well as the stamina, are five and hypogynous, and by its 

 minute embryo. Cuttings and seeds.

 Distinguished from Caryophyllea? by the fruit not having a central separate placenta, but bearing the seeds 

 on the inner margin of the valves. The species are natives of arid situations in Europe, Africa, and South 

 America. They have not much beauty, and no known medical properties. Besides the genus here recorded, 

 there are two others mentioned by M. Decandolle. Cuttings, division, or seeds.

 These consist of herbs or low undershrubs, inhabiting the mountains and pastures of all parts of the world. 

 In Europe and Siberia they are particularly abundant, and least so in Africa and South America. Many are 

 common weeds, as most of the Cerastiums, Spergulas, and others. Several of the Silenes are very ornamental, 

 and among the Arenarias are to be found some dwarf species of considerable elegance. But it is in Dianthus 

 that the pride of the order consists : this genus is almost unrivalled for the brilliancy of its colours, the neat- 

 ness of its foliage, and the perfume of its flowers. From the finest of its species the title of the order has been 

 derived. The virtues of Caryophyllea? are slight. Saponaria officinalis, and one or two others, have been 

 praised for possessing antisyphilitic properties ; the root of Silene virginiana is reputed anthelmintic ; and the 

 Aien&ria oeploldes, being fermented, is used by the Icelanders for food. Cuttings, division, or seeds.
