The names of the classes are of very little consequence in this method, and the number of orders is not 

 to be considered as fixed. That part of a system so new and so comprehensive necessarily admits of much 

 improvement by perfecting the groups, the progress to which will more frequently be attained by subdi- 

 viding than by uniting. The names of the orders indicate at the same time examples of each, as

Sect. I. The Hortus Britannicus arranged according to the Linneean System. 



588. The plants grown in Britain, whether native or exotic, are thus arranged according 

 to the Linneean system. The genera, of which there are species natives of the country, are 

 here marked (*), for the sake of those who may wish to arrange a herbarium or growing 

 collection of indigenous plants according to this method. The authorities followed are, 

 Sweet's Hort. Suburb. Land. 1818, and Smith's Comp. Flora Brit. 1816. 



which, having but two stamens, is separated from its natural 

 family in the third class. 1 Gen. 2 Sp. 

 3. Trigynia. It contains of Piperacea, Piper. 1 Gen. 28 Sp. 



Class III. Trtandria. Stamens 3. Orders 5. 



1. Monogynia. Valeriana is placed here because most of its 

 species have three stamens. Here also we find the sword- 

 leaved plants, Iris, Gladiolus, Ixia, &o, also Crocus, and 

 numerous grass-lite plants, Schanus, Cyperus, Scirpus, &c. —

 Cenchrus, *Sesleria, Limnetis. 56 Gen. 346 Sp. 



2. Digynia. This important order consists of the true Grasses. 

 Their habit is more easily perceived than defined ; their 

 value, as furnishing herbage for cattle, and grain for man, is 

 sufficiently obvious. No "poisonous plant is found among 

 them, except the Lolium temuUntum,&ziA to be intoxicating 

 and pernicious in bread. Their genera are not easily defined. 

 Linnaeus, Jussieu, and most botanists, pay regard to the 



"Class I. Monandria. Stamen 1. Containing only two Orders. 



1. Monogynia. Style 1. Containing of the natural order of 

 Jussieu, Cannea, the genera Canna, Maranta, Thalia, Phry- 

 nium ; of the beautiful order Scitaminea, Hedychium, Al- 

 pinia, Hellenia, Zingiber, Elettaria, Costus, Kasmpferia, 

 Amomum, Curcuma, Globba ; of Juncea, Philydrum ; of

Class II. Diandria. Stamens 2. Orders 3. 



1. Monogynia. This, the most natural and numerous order, 

 comprehends the elegant and fragrant Jasmines, the Jas- 

 mine, Lilac, Olive, &c. ; also Veronica, and a few labiate 

 flowers with naked seeds, as Salvia, Rosemary, Sec. natural 

 allies of the fourteenth class ; but having only two stamens, 



they are necessarily ranged here in the artificial system It
