458 JR.ivers's Catalogue of Roses. 



read before the Society on May 21. 1832. The structure of 

 the flower in the genus T^eseda has been differently explained 

 by Drs. Brown and Lindley, the latter deeming it a compound 

 flower, in which much metamorphosis and abortion obtains, and 

 Dr. Brown maintaining that the structure of the flower is sim- 

 ple. Professor Henslow has exhibited, in fullest detail, in six 

 pages of text, and thirty-eight figures, the conditions in the 

 structure of a most remarkable monstrosity of jReseda odorata, 

 with a view to its relation to the question at issue. The conclu- 

 sion he has drawn agrees with Dr. Brown's, and is opposed to 

 that of Dr. Lindley. The pamphlet, or paper, is an interesting 

 one to students of the anatomy and physiology of plants. 



Rivers, T. and Son, Nurserymen : A Catalogue of Roses cul- 

 tivated at the Sawbridgeworth Nurseries. 



This we consider to be the most useful catalogue of roses 

 in the English language ; because the species and varieties 

 are not only classed, and their colours given, as in our 

 Hortus Britanniciis, and in the Hortus Addlestonensis and 

 Hortus Duroverni, but a short description of each flower is 

 added. To convey an idea of the completeness of the assort- 

 ment, we may mention that there are 13 varieties of hardy 

 climbing roses; 17 of climbing China roses; and 16 of iZosa 

 indica odorata. A strong recommendation to this catalogue, 

 in our eyes, is, that it does not contain half the number of va- 

 rieties that are to be found in the French, and in some of the 

 English, nursery lists, but a careful selection of sorts which 

 are perfectly distinct. Every person intending to purchase 

 roses should possess himself of this catalogue, which may be 

 done through the post-office, as it is only a single folio sheet 

 printed on three sides. 



The following very judicious observations on the culture of 

 roses are placed at the end of the lists. They contain the 

 essence of all that can be said on the subject : — 



" The rose, perhaps, more than any other ornamental shrub, 

 requires constant culture to make it bloom in perfection, unless 

 in the most favourable rose soils, which, in my opinion, is a 

 rich cool loam. Roses require to be removed, and to have 

 their roots trimmed, every third year : when taken up, these 

 roots will be found to have lost most of their fibres ; but, naked 

 as they are, if they are then trimmed, the branches thinned 

 and shortened, and plenty of well-rotted manure mixed with 

 the soil they are planted in, the plants will be quite renovated, 

 and bloom as fine, and often finer, than young plants. This 

 treatment, perhaps, is most applicable to standard roses ; 

 with dwarfs the trouble is too much, unless with the choicest
