" This species, interesting as the parent of the innumerable 

 garden varieties with round petals, is the largest of all the wild 

 tulips. Its tall, strong, tough scape, and its broad round petals (in 

 the wild plant, uniformly red), sufficiently distinguish it, at first 

 sight, from all its congeners. It is perfectly smooth all over." 

 It is found, without any disposition to vary, in fields at three 

 places near Florence. For the notice of this plant. Dr. Lindley 

 informs us, he is indebted to the Hon. W. F. Strangways. " No 

 synonymes beyond those of Linnaeus are quoted, because they 

 are both uncertain and uninstructive." [Bot Meg., Sept.)

A new species of this curious genus, obtained from the Swan 

 River, by Robert Mangles, Esq., in whose collection it flowered 

 in May, 1837. " It grows very well in a green-house, and would, 

 probably, succeed if planted out in a pit which is well protected 

 during winter." [Bot. Beg., Sept.)

Before we give our opinion on this pamphlet, we shall quote 

 the first four paragraphs, as a fair specimen of the style and 

 manner in which the whole is written. 



" Knowing that the materials general!}' used in the construction of all hor- 

 ticultural erections, viz. wood and cast iron, has been a controverted subject, 

 and that a great diversity of opinion exists as to what description of materials 

 are of most avail, it is my intention in this brief Treatise to point out, 1st, the 

 advantages of wood over cast iron in the framework, for all horticultural 

 designs ; 2dly, the superiority of hot water over heated air and steam as a 

 medium for conveying genial heat to plants ; 3dly, the consumption of fuel ; 

 4thly, in time and labour of attendance ; 5thly, the advantage gained by water
