There are two forms of this species, diiFering very slightly from each other. 

 The first was found in Cusco, in Peru, and was sent to SpofForth, under the 

 name of the red narcissus, by J. B. Pentland, Esq., in compliment to whom 

 the genus is named; and the other was found by Commodore Sulivan, during 

 his command on the west coast of South America, in 1837. Both varieties 

 flowered for the first time in England in August, 18S9. (^£ot. Reg., Dec.)

This little plant, though its stems are very slender, has them so curiously 

 interlaced that they support themselves. Seeds of it were sent home from 

 the Swan River in 1838. It is grown in sandy loam and peat, and requires 

 plenty of water during the growing season, with perfect drainage. (^Paxt. Mag.

Art. VI. On Conservative Walls, and their Superiority, as Sources 

 of Botanical and Floricultiiral Interest, to Green-houses and Con- 

 servatories. By the Rev. T. Bainbridge, M.A. 



I HAVE often wondered that more has not been said in your 

 Magazine, than has hitherto appeared, on the subject of con- 

 servative vi^alls. No one who has watched, for the last six or 

 seven years, the conservative wall in the Horticultural Society's 

 garden, can have failed to be struck with the great beauty and 

 variety, joined to rarity, which that wall has displayed. Not 

 only may the plants of the South of Europe, which are too 

 tender to stand in the open garden, be brought to flower and 

 fruit against such walls, but almost all the shrubs and trees of 

 New Holland and Australia will grow against them with great 

 vigour in the summer season ; and, even if they are killed down 

 to the ground during winter, if their roots are kept dry and 

 protected through that season, they will spring up again the fol- 

 lowing summer with vigour. How different the appearance of 

 the acacias and eucalypti of New Holland, when grown against 

 such walls in the open air, from what they are when grown 

 in pots under glass ! The appearance made by the common 

 myrtle, the pelargonium, the passion-flower, the loquat, the ca- 

 mellia, Lagerstroe^mm indica, metrosideros, melaleuca, myoporum, 

 and hundreds of others that will readily occur to every gardener, 

 when planted against such walls, and properly treated, surpasses,
