GREEN-HOUSE — REPOTTING. [March 



AcMmenes—^oui sixteen species. The type of this new 

 genus has been long known in our collections under the 

 name of Trevirdnia coccineaj now A. coccinea, flowers bright 

 scarlet; A. longifloraj large blue; A. gramliflora^ fine rose; 

 A. hirsuta^ bright rosy purple ; A. rosea^ profuse flowering, 

 and A. pictay the foliage of which is beautifully variegated 

 and striped; A. pedunciilata, spotted; A. elegans, purple; 

 A.pi/ropa- A. patens 'y with a host of other new and worth- 

 less sorts, all inferior to the above, though some of them 

 cost us half a guinea each. They have all scaly tuberous 

 roots requiring the pots to be kept entirely dry during winter; 

 in this month they should be taken from the old soil and 

 planted into fresh, giving gentle waterings till they begin to 

 grow. They delight in a warm close moist atmosphere, and 

 will bloom freely from July to October. (Soil No. 10.) 



Aloe. Nearly a hundred species of grotesque-looking 

 succulent plants, and are principally natives of the Cape of 

 Good Hope, and, consequently, will do well in the warmest 

 part of the green-house, although, when convenient, they 

 frequently get a situation in the hot-house. A. vulgaris, 

 known as A. harbadensis, has orange yellow flowers; A, 

 ohliqua, now called Gasteria obliqua ; A . dichotoma, and A, 

 variegdfa, which is perhaps the finest of the genus: the 

 leaves are beautifully striped, and commonly known as the 

 partridge-breast Aloe; flowers scarlet and green. They ought 

 to have very little water; once a month is sufiicient. They 

 would grow without it, and several of them would also grow 

 by being suspended in the house, without earth or any sub- 

 stitute about their roots, by being frequently sprinkled with 

 water. Few of them are admired for the beauty of their 

 flowers, but the whole are considered curious. They flower 

 from May to September. (Soil No. 9.) 



Alo7isdas, five species, all soft- wooded, small, shrubby 

 plants, with scarlet flowers. A. incisifolia is known among 

 us under the name of Hemimerls urticifolia^ and A. linedris 

 as H. linedris. If well treated they form very handsome 

 plants, and flower freely. They will not bear strong fumi- 

 gation ; and, when the house is under that operation, they 

 must be put on the floor of the green-house, where they will 

 not be so much afi'ected. They flower from April to August.
