sirable plant. In many of our winters, a pit, cold frame, or even a mat 



nailed against a wall, will probably preserve its life through the winter. 



Bertero, the late botanical traveller in South America, had thought the 



shrub to be the type of a new genus ; but Dr. Hooker and Mr. Arnott 



have deemed it to belong to the genus Adesmia. 



Mr. Thomas Bridges, collector of natural productions in South America, 



in a letter dated Valparaiso), Oct. 25. 1832, thus speaks on this plant : — 



" Bertero has dedicated a genus to Mr. Loudon ; a beautiful plant found 



sparingly about Valparaiso, Loudon^ «nthylloides. If Mr. Loudon do not 



possess specimens [through the kindness of Mr. Hugh Cuming, he does], 



I will send one when I have returned from Chiloe." 



Ackcia. decipiens var. prEemorsa, noticed in our last (p. 365.), is figured in the Botanical Ma- 

 gazine for June, t. 3iJ4+. 



Mimosa latispinosa, the leaves of, have, we have been recently informed, 

 been observed to possess a degree of the sensitive property which is so 

 obvious and well known in the humble plant. Mimosa pudica.

C. speciosa, on a hot dry bank or bed, when the sun is shining full upon 

 it, with all its large rich crimson blossoms fully expanded, and reposing 

 upon the soft velvety bed formed by its succulent leaves, is a most beau- 

 tiful object. It is a hardy annual, propagated readily by seeds, which it 

 bears in great abundance. It loves dry and exposed situations, and flou- 

 rishes most in scorching weather; but it should be grown in tolerably 

 rich soil ; or, if in very poor soil, it should be sown thick. Under the 

 former circumstances, it forms a patch a foot and more in diameter ; in the 

 latter case, its branches are not above two or three inches long, as in the 

 wild specimens sent home by Mr. Douglas (who introduced the species), 

 and in the London Horticultural Society's possession. It flowers in May 

 or June, if sown early ; or in September and October, if later. It is a 

 plant eligible for cultivating on rockwork, in a sunny aspect. {^Bot. Reg.,

" Introduced by Mr. Lee. It flowered with us abundantly in May. 

 The flowers are very angular in their form ; and the opening is perfectly 

 square, which has suggested the specific name." (Bot. Cab., July.) 



'EricecB § WiodordcecB . Of i?hododendron campanulatum, introduced, 

 according to the Hortus Britannicus, in 1817, a figure is published in Lod- 

 diges's Botanical Cabinet for July, t. 1944. Messrs. Loddiges raised it 

 from seeds in 1825. The head of blossoms depicted show it to be a superb 

 species. The flowers are large, and in colour white ; but clouded and 

 margined with lilac or a pale purple. R. campanulatum is a native of 

 elevated situations in Nepal ; and may, perhaps, bear our winters unin- 

 jured. " During the last two, sevei'al plants have remained well out of 

 doors with us. The young leaves are at first purplish underneath ; they 

 then become milk-white ; and afterwards, when quite hardened, change to 

 a kind of tan colour. It flowered with us in April, kept in a cold frame. 

 We have succeeded in propagating it by layers as well as by cuttings, in 

 soil formed of loam and peat " Mr. Loddiges, sen., deceased, was the first 

 who had for sale the R. ponticum, now so general an ornament to the 

 flower-gardens of this country. " He also introduced the Chamseclstus 

 caucasicum and chrysanthum ; and, lately, we have added to the number
