SWEETS HORTUS BRITANNICUS; or, a Catalogue of 



all Plants cuLTivATEDintheGARDENs, or found wild in Great Britain, 

 arranged according to the Natural Orders to which they belong. By Robert 

 Sweet, F. L. S. One thick vol. 8vo. 1/. Is. 



" It certainly is the most complete and useful Catalogue that has yet appeared, as, In 

 one line, it gives the systematic and English names, where described, of what country it 

 is native, the year introduced, the months when in flower, whether hardy or tender, its 

 duration, and reference to the books in which it is figured ; and where any names have 

 been lately changed, a synonyme is given in Italics, to shew what it is changed from. It 

 also contains nearly double the number of plants contained In any other Catalogue that 

 we have seen ; so that, on the whole, we believe it could not have been more complete. 

 In our opinion, the arrangement according to the natural system is far preferable to that 

 of an artificial one, particularly for cultivators ; and on this account the present work 

 should be in the hands of all gardeners and cultivators of plants ; and the reference to 

 the figures will also render it very useful to the botanist." — Gentleman's Magazine for 

 Jan. 1829. 



A Fifth Edition, considerably enlarged, is in t!ie Press, of 



The HOTHOUSE and GREENHOUSE MANUAL, or BOTANI- 

 CAL CULTIVATOR; giving full Practical Instructions for the Management

 ders, in the Gardens of Great Britain. With Plain Directions for the Manage- 

 ment of Bulbs and Plants in Rooms, &c. 12s. By Robert Sweet, F.L.S. 



M Indeed, what Mr. Sweet has said on the culture of Bulbs and Epiphytes, in the last 

 edition of his Botanical Cultivator, may be considered as the ultimatum on this subject for 

 the British Gardener.*' — Gardener's Magazine.
