22 MISCELLANEOUS INTELLIGENCE. 



dots at the base, and a heart-shaped blue spot above the base, which at 

 bottom is tomentose and black." The Iris tricuspis : — " Border of the larger 

 petals white, suborbiculate, (roundish,) with a point, claws green on the outside, 

 yellow within, dotted with black. Smaller petals several times shorter, claws 

 convex on the outside, green, concave within, dotted with brown, the length of 

 the larger ones but narrower. It varies in the shape of the larger petals and 

 very much in the colours, blue, purple, yellow, white, and, spotted." He then 

 gives Curtis's description of [the flower: — "Three of the petals large and white 

 with a brilliant blue spot at the base of each, edged on the outer side with deep 

 purple." - 



Redoute, a French botanist who wrote upon liliaceous plants, changed the 

 name of the genus to Vieusseuxia, which, although rejected by Aiton, has been 

 adopted by Sweet and Loudon, and will probably be retained, having been 

 adopted by De Candolle. 



It appears to me that the confusion has arisen from Curtis, in his Magazine, 

 calling the tricuspis " Iris pavonia." From Burriensis's statement, it is ap- 

 parent that the bulbs sold in the seed shops as Iris pavonia, arc the fieus- 

 setixia tricuspis, and the Iris pavonia, second size, (Lockhart) or Iris pavonia 

 minor of other shops, is the Morcea tenuis or brown flowered Morsea of the 

 Hortus Kewensis, of which a figure will be found in the Botanical Magazine, 

 1047. This plant was introduced in 1807, and is, like the two others, a native 

 of the Cape of Good Hope. 



It' Burriensis wishes to get the true Vieusseuxia (Iris or Moreea) pavonia, he 

 must apply to some of the great nurserymen near London, in particular any 

 of them who have a correspondent at the Cape of Good Hope; and failing 

 there, to the Botanic Gardens of Liverpool or Glasgow, both of which dispose 

 of plants. 



1 observe both Iris pavonia and Iris tricuspis in page of Southampton's Pro- 

 domus, published in 1818; but, as he makes the colour of both black and white, 

 there appears some danger of a mistake.

On Euf.ction of a Greenhouse, &c. — I shall not pretend to give instruct ion 

 to your " Country Subscriber" (page 89, April, 1839), regarding his greenhouse, 

 but would recommend him to consult some of the new publications on the 

 subject. I can, however, give him some hints, having myself erected one many 

 years ago. After it was built a professional man recommended a flat stage, 

 which I had accordingly, but J found it kept the plants too far from the glass, 

 (which would be still more objectionable for geraniums, which grow better near 

 the glass) and drew the plants, and I was forced to put up the usual stage. 1 

 do not like the back light as exhibited in the sketch, as it will make the house 

 cold in winter, and will recpaire an additional power of betting. I have no 

 practical knowledge of Amott's stove; (although the objection of a dry heat 

 would be easily removed by putting a flat iron dish with water on the top of it;) 

 I would prefer the heating with hot water, or even common flues to it. I would 

 recommend good Norway timber well seasoned before it is put together, (and 

 if Kyanized, cut before it is done so) ; and if I were building a greenhouse at 

 present, I would do it upon the plan of Messrs. Chandler's camellia house at 

 Vauxhall, where the top sashes are all fixed, every third or fourth astragal being 

 stronger than the rest, whereby a great saving of material is effected. Your 

 correspondent will find a picture of it in the "Gardener's Magazine" some 

 years back. I would ventilate the house from the front upright sashes, and 

 two ventilators at the back. The panes of glass should be square, either four, 

 five, or six inches; if one is broken it can be used by turning it. I had vines in. 

 my house for some years, but took them out because they required heat in the 

 spring more than suited a general collection of greenhouse plants ; but gera- 

 niums bear forcing better than the heaths and other plants usually found in 

 greenhouses. The panes of the roof should be puttied with black putty — it 

 prevents breaking from frost. 



From the alteration in the mode of charges in postage, it is obvious that 

 many of the smaller flower seeds can be sent by post at a small expense. It 

 would saye correspondence if your advertisers would annex the prices, (more
