1. Rhododendron arboreum, var album. Tree Rhododendron; white-flowered 

 variety. Synonym, R. album. Decandria, Monogynia. Ericeae. This 

 beautiful variety of the Tree Rhododendron, flowered in great perfection in 

 the Conservatory of Robert Baxter, Esq. Dee Hills, near Chester, in 

 February, 1831. It was raised from seeds sent by Dr. Wallich to Mr. 

 Shepherd, of Liverpool, about twenty years ago. In the List of Plants of 

 the Hon. the East India Company's Museum, Dr. Wallich gives this plant 

 as a native of the high mountains of Nepal, where he gathered it in 1821. 

 Dr. Hamilton appears to have first discovered the plant on a mountain at 

 Karainhatty, in 1803. It flowered for the first time in Europe, in j\lr. Bax- 

 ter's collection. Rhododendron, from Rhodo, a rose; and deudron, a tree. 



2. Tradcscantia pilosa, Hairy Spiderwort. Hexandria, Monogynia. Com- 

 melineoe. Roots of this plant were suit by Dr. Drummond, from Louisiana, 

 to the Glasgow Botanic Garden, where it flowered during the autumn of 1833. 

 Stem grows two to three feet high. Flowers numerous in terminal umbels, of 

 a bright purplish blue, with yellow showy anthers. Culture— it requires the 

 same treatment as the common border T. Viginica, from which plant it differs 

 by having extremely hairy leaves. Tradcscantia, from Mr. John Tradescant, 

 Gardener to Charles I. 



3. Lobelia pubcrula ; Blue downy Lobelia variety. Syn. Lobelia puberala, 

 var. glabella. Pentandria, Monogynia. Lobeliaceae. This is a highly in- 

 teresting addition to our Garden Lobelias, and was introduced last year by 

 Mr. Drummond, who sent the seeds from Jacksonville, in Louisiana. The 

 species appears, indeed, to be little known even to the American Botanists, 

 and is probably confined to the Southern States. lis nearest affinity is per- 

 haps with L. syphilitica, but its spike is less dense, and vastly more elongated, 

 its flowers smaller, of a brighter purplish yellow, with two white spots on the 

 lower divisions of the corolla. The spike rises about a foot high. Culture — 

 The plant is perennial, and increased by division. Lobelia, from M. Lobel, 

 a celebrated botanist.
