FIRST 



ADDITIONAL SUPPLEMENT. 



V* The alphabetic mode of arrangement has been adopted to avoid the necessity of a second Index. The 

 number prefixed to each genus and species declares the relative place for each in the Hortus ; and 

 such genera as have not been inserted there have here a star (*) prefixed to them, their etymology- 

 given, and their Linnean class and order, and Natural order, stated. In the copies of the Hortus 

 Britannicus which may hereafter be printed, stars will be inserted into the plates wherever the addi- 

 tions made in the Supplement come in, in order that the reader may be apprised of their existence, and 

 lose as little time as possible in turning to them. 



The species to which this character ($) is prefixed are those which have been raised in the Exotic Nur- 

 sery of Mr. Joseph Knight, King's Road, Chelsea, from seeds collected and brought home by Mr. Baxter. 

 The names of these species have been verified and authenticated by Mr. Knight's very able and intelli- 

 gent foreman, Mr. Alexander Scott, who, while he trusts that each may be found accurately denomi- 

 nated, nevertheless reminds us that Proteaceous plants are subject to great variation in foliage, in their 

 progress upwards from a seedling state. Besides the above, Mr. Baxter's seeds have produced various 

 other species of Banksia and Dryandra, and species of Petr6phila, Oxylobium, Mirbeb'a, Gompholobium, 

 Hdvea, Burtom'a, Pultense^a, Brachysema, Kennedya, Daviess, &c. : many of which, when farther 

 advanced in growth and age, may prove to be new species. 



Whoever wishes to ascertain the additions and improvements made subsequently to the present Addi- 

 tional Supplement may consult the Gardener's Magazine; in which, under the article, which will 

 henceforth be contained in every number, entitled, " Floricultural and Botanical Notices of New Plants, 

 and of Old Plants of Interest, supplementary to the latest editions of the Encyclopaedia of Plants, and 

 of the H6rtus Britannicus," will be found the name of every plant newly introduced or originated, and 

 every recent improvement in botanical nomenclature. At the close of every year, or of every two 

 or three years, according to the accumulation of matter, these names and improvements will be collected 

 and published in additional Supplements similar to the present one.
