front, and of any required length ; dig out the original soil 

 within the frame to the depth of 1 6 inches, and fill up to the 

 old level with the following compost; viz. one third leaf mould, 

 one third turfy peat recently taken from the moor, the remain- 

 ing third half sphag'num, (that is, living plants of bog moss,) 

 and half sand, the whole well broken and mixed together, but 

 not sifted. In this the roots are planted, and some care taken 

 to keep the surface higher for those kinds which require less 

 moisture, such as Cypripedium arietinum and others. Regular 

 watering and ocasional shading is necessary ; and sufficient air 

 must be admitted to prevent the plants from being drawn. 

 The plants flower in the early part of summer : — in autumn 

 the old stems are cut away, and a slight dressing of the compost 

 given, and during hard frost the frame has a covering of mats. 

 A North American summer and winter are thus successfully 

 imitated, and the American Orchideae cultivated with the most 

 complete success. {To be continued.)

No. IV. for April, contains 



2727 to 2728. — Caryocar nuciferum, Souari, or Butter Nut of the shops, 

 16 and 4, and Rhizoboleae. Arborescent, the tree attaining a very considerable 

 size ; native of S. America. The flowers are very large, the calyx two inches 

 broad ; the corolla consists of five large elliptical concave petals, purplish 

 brown outside, and yellow and red inside ; stamens exceeding 4900. This 

 plant has not been introduced in a living state, but the present figure is from 

 drawings by the Rev. Landsdown Guilding of the island of St. Vincent. 

 {Gard. Mag. vol. i. p. 193.) The kernel of the butter nut is said to be of 

 a pure ivory white, soft and fleshy, somewhat oily, and of a very agreeable 

 flavour ; it is not uncommon in the London fruit-shops. 



2729 to 2735. — Maxillaria Parkeri, Neottia grandiflora, Houttynk cor- 

 data, Scaevola Kcenigii, and Campanulata Prismatocarpus. 



That distinguished botanist, Dr. Hooker, having undertaken the editor- 

 ship of this parent of botanical periodicals, has conferred on it a new inter- 

 est and vigour, such as might reasonably have been expected from the 

 author of the " Exotic Flora." One feature, which we entirely approve, is 

 the introduction of figures and descriptions of plants, which, though not
