Gerahiacecr, or the Natural Order of Geraniums, 

 by R. Sweet, F.L.S. 



This work belongs more to the florist than the botanist ; for 

 out of the four plates in this number, only one represents a 

 real species, the Pelargoimim Cotyledonis of Willd. 



This plant is formed into a new genus by the name of Iso- 

 petalum Cotyledonis, of which the following are the characters : 



Gen. Ch. Cal. 1-sepalus, 5-partitus, lacinia suprema desi- 

 nente in foveolum nectariferum. Pet. 5 aequalia rugosa. Stam. 

 tubo brevissimo : 5 — 6 fertilia patentia apice incurva ; sterilia 



inaequalia subulata incurva. Spec. Ch. I. pedunculis pro- 



liferis : umbellis compositis, foliis cordatis peltatis rugosis pu- 

 bescentibus subtus tomentosis, caule crasso carnoso. 



In a work like the present, intended more for amateurs, it 

 would have been much better had the Latin characters been 

 rendered into English ; and those given to the mule plants left 

 out altogether, as being equally useless both to the botanist and 

 to the cultivator. 



AMonograph of the British Grasses, by G. Graves, F.L.S. No. 1. 

 This is a very useful and a very cheap publication, got up 

 with great neatness, and the plates on much better paper than 

 the last three works. Indeed, while on this subject, we would 

 strongly reconmiend the publishers, both of the Register and 

 Magazine, to pay a few shillings more per ream for their plate 

 paper ; for the beauty of the figures is greatly lessened by the 

 letter-press bemg seen through the thin paper they now use for 

 the plates. Of this work, the first number contains twelve 

 plates, at the price of 4s. 6d. plain, or 65. coloured. The de- 

 scriptions are iiitelligible to every one, and the work alto- 

 gether promises to become a particularly useful one, as being 

 within the reach of the farming community. 



Loddigei Botanical Cabinet. No. 64. Price 2s. 6d. 

 It is a great pity this neat and moderate priced little work 

 does not contain either botanical characters or synonyms; 

 these additions would render it as valuable to the botanist, as it 

 now is to the cultivator : From this cause we are unable to 

 ascertain those which are already described. The designs and 

 the engraving of the plates are very neat and accurate, but we 

 think the portions of each which are coloured, should be done 

 with more care. We should then strongly recommend this 

 work to young persons fond of flower drawing, as offeruig them 

 a pleasing and an improving occupation in finishing and colour- 

 ing the plates, according to the portion which is done in each.
