A collection of British Plants is exhibited in glazed frames fastened by hinges to uprights. The classification of the Flowering Plants and Ferns is that used in Bentham’s “Handbook of the British Flora,” and descriptions are attached as labels to each plant.[29] Three series of frames contain specimens of the British Flowering Plants and Ferns. The fourth frame is occupied with the Mosses and Stoneworts (Characeæ), and forms the beginning of the exhibition of Cellular Plants. The series is continued in the frames on the other side of the gallery containing the lower Fungi and coloured drawings of the larger Fungi; a small series of the larger kind of Fungi found near London is also shown. In the first bay to the right on entering are series of coloured drawings (natural size) of edible and poisonous fungi, and of field and cultivated mushrooms and poisonous or worthless species often mistaken for mushrooms. A _Guide_[30] to the latter series has been prepared. The British Lichens are arranged in a cabinet of shallow glass-topped drawers. [Sidenote: Herbarium.] Above the entrance to the great Herbarium is a life-size photograph of an Orchid (_Phalænopsis_) from the Philippine Islands. The portion reserved for the use of the scientific student consists mainly of the great Herbarium of Flowering Plants. This is a collection of dried plants, respectively fastened on single sheets of stiff folio paper, and representing, so far as it has been possible to obtain them, every species of living plant and the distribution of each of these on the surface of the earth. The various species are collected under their respective genera, which are arranged in their natural orders; the whole being classified according to the system of Bentham and Hooker’s “Genera Plantarum.” The plants of the British Isles form a small separate collection. The important herbarium of Sir Hans Sloane is kept distinct in its original form, the plants being pasted on the pages of 333 large folios. There are other ancient herbaria of great historic and scientific interest, as well as an excellent working library and a collection of drawings of plants. The Herbarium of Vascular Cryptogams (Ferns) and Cellular Plants (Mosses, Liverworts, Algæ, Lichens, and Fungi) is in a separate room entered from the head of the great staircase.
