or its beautiful blossoms. It produces a tolerable succession of flowers 

 for several months, and, it is hoped, will soon become common, as it in- 

 creases readily by its creeping root-stocks. It would be a most lovely object 

 if grown in a bed several feet long, where its gay colours could be seen in a 

 mass, and where new flowers would be constantly succeeding the old ones." 

 Mr. Sweet kindly informs us that this beautiful plant is by no means refer- 

 able to the genus i^ris, but that it is a genuine and third species of Salis- 

 bury's genus Dietes {dis, twice, etes, an associate; related to /^-is and 

 MoraeV, its species having been referred to both). — 1405. ffinothera 

 *bifrons. This very interesting garden variety was obtained in the Horti- 

 cultural Society's garden, by Mr. James Ewing, between (E. ?-6seo-alba 

 and CE. Lindley«HO. To the fine full flower of the former it adds the 

 deep crimson spots of the latter; and in mode of growth is, as it were, 

 intermediate between the two : less bushy than CE. ?'6seo-alba, more erect 

 than CE. Lindley«?20. Poor gravelly soil best suits the annual Oenotheras.

Ko. XXII. for March, contains 

 85. Jsclepiay virgata. A pretty white-flowering species from INIexico, 

 hardy enough to live through our winters without covering, if planted in a 

 warm sheltered south border. Succeeds well in heath mould, or in the 

 usual soil of gardens if light and rich. It is of elegant growth, and flowers 

 abundantly, and may be increased, by dividing at the root, or by seeds, 

 which sometimes ripen. — 86. LobehV? decurrens. A rare and interesting 

 species, raised at Bury Hill from seeds received from Chile in 1829. " In 

 the garden at Bury Hill it was planted by the side of a wall, in a southern 

 aspect, in rich light soil, it grew freely, and flowered in the autumn, 

 and was still in fine bloom at the beginning of last October. The milky 

 juice of this species is particularly acrid, and renders caution in the hand- 

 ling of it proper. " Cuttings of it will doubtless root readily in a little 

 heat, like the other species of this tribe ; but it will be best to dry them a 

 day or two before planting, to close the wound, otherwise they will be 

 liable to rot or damp off"." — 87. *Centrocarpha D. Don (kentron, a sharp 

 bristle, and karphos, chaff"; sharp bristles terminating the chaff") *grandifl6ra 

 Sweet, Great-flowered Centrocarpha. This, the Rudbeck/rt nudicaulis 

 Nut., but not of others, is a very ornamental herbaceous plant, and 

 most desirable in ever\' flower-garden. The genus Rudbeckia includes dis- 

 cordant species, and Centrocarpha will receive several of them. — 88. 

 Cummingia *trimaculata. A lovely addition to our collections, and " will 

 require precisely the same treatment as the other Chile and Mexican 

 bulbs; that is, to be planted in a light sandy soil, and to be covered up in 

 severe frost." Figured from the Chelsea botanic garden, the bulbs having 

 been presented to Mr. Anderson by Miss Reinagle, who had received them 

 from their native places of growth in the vicinity of Valparaiso, in Chile, 

 where they were collected by Miss White (now Mrs. Miller), daughter of 

 the British Vice-Consul at that place. With these bulbs several other 

 curious plants were forwarded, and amongst them apparently a third species 

 of Cummingirt ; which, however, has not j'et blossomed. In a collection of 

 dried plants lately received by INIr. Lambert, from Mr. Thomas Bridges, 

 now resident at Valparaiso, there are fine specimens of the present species, 

 C. trimaculata, and also of another, which it is ver}' probable will prove to 

 be the same with that one from Miss Reinagle which has not yet blos- 

 somed, and which Mr. David Don proposes to name C. *tenella." 



Ko. XXIII. for April, contains
