 Octandria Monogyuia. 'J'ropeoleK. This plant has been lately introduced 

 from Buenos Ayres. It has a tuberous root, from whence arises a climbing 

 stem to the height of two feet or more, producing abundance of flowers during 

 the summer months. It requires the greenhouse protection, and may be in- 

 creased by cuttings, and should be potted in rich loamy soil. Flowers, a fine 

 light red; the end of the petals green. The flowers are very singular and 

 handsome. Tropceolum, from Tropseum, a trophy; leaf and flower.

 of New Holland; introduced in 1831. It grows rapidly, and forms a good 

 sized bush, with many succulent branches-, each producing plenty of flowers, 

 which continue successively from June till Autumn. Flowers campanulate, 

 one inch across, pale blue. Culture : it requires a warm greenhouse, increases 

 readily by cuttings, and sometimes bears seeds; the soil should be a rich loam.

1. Dianfhus superhus. Superb Pink. Decandria Trigynia. Caryophyllese. 

 Old authors extol this species for its fragrance. Parkinson calls it the 

 feathered pink of Austria, and says it is of a most fragrant scent. The 

 Dianthus superbus is of short duration, which accounts for its scarcity in small 

 collections. It requires to be propagated annually, by layers or by cuttings. 

 It merits a place iu every flower garden. Its ])retty pale lilac coloured fea- 

 thery flowers, being produced abundantly, gives the plant a most pleasing ap- 

 pearance, in addition to theirperfume. There is awhite variety of this species; 

 but it is rare. The plant grows from two to three feet high, and flowei-s from 

 June to September. Dianthus, from dias, Jove; and anthos, a flower. 



2. Li/ium martagon, white martagon. Hexaudria Mouogyn'a. Tulipacea. 

 The white variety of martagon is of somewhat more delicate habit than the 

 common, and of a smaller growth. It succeeds best in sandy loam. Lilium : 

 the Greeks are supposed to have derived their Leirion, a lily, from Leios, 

 handsome.

 dria, Monogynia- Tropreoleffi. See page 154. 



4. Eryngimn alpiniim, Alpine Eryngo. Pentandria, Digynia. Umbelliferae. 

 The Eryngium alpinum, with its fine feathery involucre beautifully tinted 

 with blue, long continuance in perfection, and general singularity of effect, 

 is worthy of a place in every garden. Culture: it may be propagated by 

 division of roots, or by short cuttings of them, and also by seeds. Eryngium, 

 from Eryggauo, to belch; expels wind. 



On the Cultivation of Epiphytes of the Orchis Tribe. By Dr. 

 LiNDLET, F.R.S. &c.. Assistant Secretaiy. 



This class of plants is comparatively new to Europe, having been generally 

 speedily lost after their introduction. The Vanilla seems to have been almost 

 the only species that was known in Euglaud in the time of Miller, and little 

 more than twenty were to be found in the Kew Garden during the last ten 

 years of the last century. Not more than twelve or fourteen species had beeu 

 added to the same garden, in the first thirteen years of the present century ; 

 and «m)y nineteen species are mentioned as iu the Berlin Botauic Garden, one 

 of the richest iu Europe, in 1822. 



It was supposed that this want of success was owing to some peculiar diffi-
