would be 15s to 20s each volume, without plates, and 20s to 25s, with 

 plates. 



The Colonies marked with a star, all require to be explored by 

 collectors previous to the publication of their Moras ; the others might 

 be commenced forthwith. 



To secure uniformity of plan, and due attention on the part of 

 the authors to the convenience of the public and requirements of 

 the Colonies, the following instructions for their guidance were drawn 

 up at Kew, and after being submitted for approval to several expe- 

 rienced Botanists, have been adopted with regard to the only Flora 

 hitherto published, that of Hong-Kong. 



" The Floras of the British Colonies are to contain concise and 

 " characteristic descriptions of all Phamogamic plants and Ferns 

 " known to inhabit the several Colonies. These descriptions to be 

 " drawn up in English, from the actual examination of all available 

 " specimens, by the authors severally selected for the purpose.* 



" Each Flora to commence with an analytical table of the Natural 

 " Orders it comprises, containing the most prominent differential cha- 

 " racters only, as exemplified in the species representing the order in 

 " that particular Flora. 



" Under each Natural Order, after a concise ordinal character, 

 " drawn up with special reference to its representatives within the 

 " Flora, there shall follow a note of its distribution and such observa- 

 " tions as may be necessary to facilitate its recognition, or to under- 

 " stand its limits and affinities ; and following these, an analytical 

 " table of its contained genera, when more than one. 



" In like manner, under each genus, the generic character and dis- 

 " tribution, &c. will be followed by an analytic table of the species, 

 " when more than one. 



" Under each species will be given, 



" 1. The description above mentioned. 



"2. A select synonymy, with especial reference to works already 

 " published on the Colony, and to one work where the general syno- 

 " nymy, or a more detailed account of the species may be found. 



" The localities of the species, in more or less detail, according to 

 " the extent of the country it inhabits, together with the name of its 

 " discoverer or collectors when of unusual occurrence. 



" An abstract of the extra- colonial range of the species. 



" A notice of its economic value in arts, manufactures or medicine, 

 " where necessary. A general list of such useful species with their 

 " nature and colloquial names, when of sufficient importance, will be 

 " appended to each Flora. 



" The plants to be arranged under the Natural Orders contained 



* In the case of certain genera or even families, it may be found desirable that 

 they should be described by Botanists eminent for their knowledge of that particular 

 group, rather than by the author of the special Flora in which they occur. In all 

 such cases the selection of an author must be authoritatively sanctioned.
