A great part of Linnams's Didynamia Angiosp^rmia is found here, capsular fruit and didynampus stamens 

 being among the most obvious characteristics of the order. The species are generally herbs with opposite 

 leaves, very rarely shrubs : and natives of mountains, valleys, ditches, woods, and waysides, in all parts of the 

 world. The Personate have the palate so prominent as to close up the orifice of the corolla. Ringntes have 

 the palate open. Some are highly ornamental, as DigitMis, .Pedicularis, Calceolaria, &c., others are mere 

 weeds, as is the case with a large proportion of them. Most of them have a weak unpleasant smell, a bitterish 

 taste, and acrid and suspicious properties ; but this odour is sweet and aromatic in the Ambulia of Lamarck , 

 the taste is refreshing in jl/imulus luteus, which is a culinary plant in Peru, and the ordinary acrid properties 

 become emollient in some Antirrhinums. The Rhinanthacea? are remarkable for their astringent tonic bark 

 and leaves. The leaves and roots of Scrophularia aquatica, Gratlola officinalis and peruviana, and Calceolaria 

 act as purgatives, or in strong doses produce vomiting: these properties exist, in a high degree, in Digitalis 

 purpurea. The leaves of this plant, reduced to powder, excite vomiting and vertigo, excite urine and saliva, 

 and lower the pulse : in top strong doses they cause death ; in moderate doses they are useful in scrophula, 

 dropsy, asthma, &c. Cuttings, divisions, and seeds.

A portion of Diandria TVIonogynia, and the whole of Didynamia Gymnospt>rmia, of Linnaeus, make up 

 Labiataj, which are character! sod by their didynamous stamens, four little nuts or naked seeds, single style, and 

 irregular corolla. They are mostly natives of extra-tropical countries, although under the form of 'Hyptis, 

 Anisomeles, Leucas, CKcymum, &c., they are found in the hottest zones of the world. Many are extremely 

 odoriferous in the leaves, some bear handsome flowers, but by far the greater part are no better than weeds. 

 They are all remarkable for their tonic, cordial, and stomachic virtues : they contain both a bitter and an 

 aromatic principle, in different proportions. The bitterness which is given out in decoctions, resides in a gum- 

 resinous secretion, abounding in some Teucriums, which are particularly employed as stomachics^ and some- 

 times as febrifuges : those which abound in essential oil, and which are consequently aromatic, are used as 

 stimulants. From the different degree of combination of these principles in different plants, they have obtained 

 various uses ; such as savory,thyme, marjoram, for the seasoning of food ; sage, balm, ground ivy for tea ; marum, 

 tnajoram, lavender, and thyme for sternutatories ; others, such as lavender, mint, balm, and rosemary, for 

 perfumes. It is a remarkable fact, that the essential oil of all contains camphor, which exists in such quantity 

 in sage and lavender, that it has been supposed that the separating of it might become an object of commerce.
