which should be done when it is at rest. Plants of it have been flowering at 

 Kew for these last two months, and are now in great perfection. 



Phaius Wallichii. This stately Orchid belongs to a genus which contains 

 some of the most ornamental plants in cultivation. They are natives of the 

 East Indies and China. Potted in turfy loam, intermixed with rough peat and a 

 little sand, they grow vigorously, and produce abundance of large rich-coloured 

 flowers. 



Phaius grandifolius (or the Tankerville Phaius), although an old plant, 

 richly merits cultivation. Several plants of it are flowering at Kew in great per- 

 fection ; some of the flower-stems are five feet high, with eighteen expanded 

 flowers on them. 



Phaius intermedius resembles the other two in habit, and is a very hand- 

 some species. The leaves are from three to four feet long ; the flowers are 

 large ; the sepals and petals are white externally, and of a yellowish brown 

 within ; lip whitish, mixed with purple. 



Phaius bicolor. This is a very elegant species, much resembling P. Wal- 

 lichii, but of a somewhat dwarfer habit ; it grows about two or three feet high ; 

 sepals and petals pale yellow externally, and of a deep chocolate-brown within; 

 lip yellow, Avhite, and rose-colour. Several other species belong to the genus, 

 but these four may be considered the best for general cultivation. 



LupiNus Hartwegii is a half hardy annual, and very showy. If raised in a 

 frame and bedded out, it attains the height of one and a half or two feet, and 

 has a raceme of brilliant blue flowers tinged with red or purple. Its native 

 country is Mexico. 



LupiNus PUBESCENS. A half-hardy species, allied to L. Bogotensis. It re- 

 quires a treatment similar to L. Hartwegii ; it grows from one to two feet high, 

 and bears a raceme of violet-blue flowers. Native country Guatemala. This 

 and Hartwegii are figured in the Magazine of Botany for March. 



Thibaudia macrantha. a rather straggling evergreen stove or warm green- 

 house shrub, of easy cultivation, allied to the common Bilberry. It is one of 

 the handsomest of the whole tribe, having large pendent flowers two inches and a 

 quarter long and one inch in diameter, of a red, yellow, and pure china white, 

 beautifully marked with wavy red lines, resembling some handsome pieces of 

 porcelain. They are produced from the woody portion of the stem, extra-axil- 

 lary, two or three springing from the same point. It was raised from seed im- 

 ported from the Kola mountain, Moulmein, by Messrs. Veitch of Exeter. 



Medimlla javanensis. An erect evergreen stove-shrub, having a terminal 

 or lateral panicle of pale rose-coloured flowers. It was imported by Messrs. 

 Rollisson of Tooting from Java. This species belongs to a genus which con- 

 tains some very magnificent flowering plants ; the present one, although forming 

 a handsome shrub, is not one of the most showy kinds. 



SoBRALiA SESsiLis. A terrestrial Orchid, rather pretty, of erect growth, about 

 two feet high, and having small flowers produced on the apex of the stems. The 

 sepals and petals are nearly white ; tinged with rose lip yellow, deeply stained 

 with rose-purple. It is a native of British Guiana, and was introduced about 

 ten years ago. 



Echixopsis campylacantha. a very handsome flowering-plant of the Cactus 

 tribe, about a foot high, between ovate and globose. The flowers are produced 

 near the summit of the plant; they are funnel-shaped, nearly six inches long, 

 with pale rose-coloured petals. It is a native of the Argentine province of Men- 

 doza, at the eastern foot of the Andes. The above four plants are figured in the 

 Botanical Magazine for March.
