NEW AND RARE PLANTS. 89 



summer came blue, the succeeding one partially so, and the third 

 year they assumed their original rose-colour. I am very desirous to 

 grow the Hydrangea with blue flowers, and shall try the charcoal 

 plan mentioned by Mr. K.; but a friend of mine tells me that at 

 Neath he saw, in a gentleman's garden, some magnificent plants of 

 Hydrangeas in full bloom, both rose-coloured and blue, and thinks 

 that no difference was made in their treatment, and that they were 

 distinct in species. If you, or any of your intelligent readers, can 

 furnish us with some satisfactory information on this subject, it will 

 oblige. S. P.

LIST OF NEW AND RARE PLANTS. 



Androsace lanuginosa. Shaggy-leaved. (Bot. Mag. 4005.) Primulaceae. 

 Pentaudria Monogynia. Dr. Royle sent this plant from the Himalaya Mountains 

 to the Dublin Botanic Garden, where it bloomed last August. It promises to 

 be hardy. The flowers are of a delicate rose colour, with a yellow eye about a 

 quarter of an inch across ; they are produced in umbelliferous heads of near 

 twenty in each. 



Becium bicolor. Two-coloured. (Bot. Reg. 15.) Labiateae. Didynamia 

 Gymnospermia. A handsome conservatory, or warm greenhouse plant, seeds of 

 which have been received from Abyssinia by the London Horticultural Societr, 

 in whose garden at Chiswick it has bloomed. It is a shrub with downy stems 

 and ovate lanceolate leaves. The flowers are produced in verticillasters, and so 

 successively as to form spikes. Each blossom is in shape like the upper hall' of 

 a tubular formed honeysuckle, an inch across the mouth, white with lilac veins, 

 producing a handsome appearance. It grows rapidly, blooms profusely, and is 

 readily propagated. 



Brassia Wray^e. Mrs. Wray's Brassia. (Bot. Mag. 4003.) Orchidaceae. 

 Gynandria Monaudria. Seut from Guatemala by Mr. Skinner, and has recently 

 bloomed in the fine collection of J. C. Harter, Esq., of Broughton New Hall, 

 near Manchester. The flowers are produced numerously ia racemes. Each 

 blossom is about three inches across. Sepals and petals are very narrow, of a 

 yellowish-green, with a few brown blotches. The lip is broad, an inch long, 

 yellow, tinged with green, and having a few brown blotches. It is a very inter- 

 esting and pretty flowering species. 



Bromheadia palustris. Marsh Bromheadia. (Bot. Mag. 4001.) Orchi- 

 daceae. Gynandria Monandria. A tall-growing, graceful plant, from Sumatra, 

 and has recently bloomed in the collection at Kew Gardens. The stem grows 

 about four feet high, having terminal spikes of flowers. Each blossom is about 

 four inches across. Sepals and calyx white. Lip white on the outside, and 

 white streaked with purple, having too a yellow eye within. 



Campanula qrandis. Large Bell Flower. (Pax. Mag. Bot.) Campanu- 

 laceae. Pentandria Monogynia. A half-hardy herbaceous plant, similar to 

 C. pyramidalis, but in its blooming is more showy. Each blossom is two inches 

 and a half across, and sometimes three, of a deep blue. The flower stems rise 

 to three or four feet high. It may be treated in all respects as C. pyramidalis, 

 kept in winter in pots in a cool frame, &c, and grown eithur in the open border, 

 or in pots in a room, greenhouse, &c, during summer. It blooms profusely 

 even in small pots, when the flower stem is not more than a foot high. The 

 plant deserves a place in every fljwer garden.
