266 Watsons Distribution of British Plants. 



We now state that the author publishes his address, which 

 is " Newport Hill House, near Barnstaple, Devon," to the 

 end of inviting contributions from every one whose attention to 

 British plants has possessed them of facts likely to promote 

 the ends he has in view : these he thus distinctly details : — 



" The author is anxious to obtain all information that 

 he can, in order to insure accuracy in the charts, tables, 

 &c, intended to be given in the proposed future edition, for 

 the purpose of illustrating the distribution of British plants 

 both at home and abroad. [See, in Hooker's Botanical Mis- 

 cellany, parts viii. and ix., a notice of several species of 

 British plants found in South America.] He has it also in 

 contemplation shortly to publish a separate work, somewhat 

 after the plan of the useful Botanisfs Guide by Turner and 

 Dillwyn. Any communications in furtherance of these de- 

 signs will be carefully acknowledged when used ; and, several 

 of his botanical friends or correspondents having signified 

 their readiness to aid him by local information, the author 

 subjoins the topics in regard to which he most desires this. 



" Corrections of any errors, and supplying of any omissions, 

 in the present Outlines. 



" Lists of species, native and naturalised, in any county or 

 smaller district, of which a local Flora has not been published 

 since the last century. To facilitate this, he will send printed 

 catalogues of the British species to any one willing to oblige 

 him with such a list; so that nothing more will be necessary 

 than attaching a mark to the names. 



" Unpublished stations for any of the species not indigenous 

 in all the six districts subsequently mentioned, with confirm- 

 ations of those resting on the authority of former botanists. 



" The highest and lowest elevations at which any species has 

 been observed. 



" Information as to the zone (as afterwards explained) in 

 which any town, hamlet, residence, lake, mountain summit, 

 &c, is situate. 



" Unpublished (or here omitted) altitudes of towns, hills, 

 lakes, &c. &c. As also, results of observations on the tem- 

 perature of the air, earth, or springs : and the quantities of 

 rain in different situations. 



" Facts in regard to the apparent influence of soil and sub- 

 jacent rocks on vegetation. 



" The author is desirous of procuring specimens of species 

 not extending into all the six districts, from various stations, 

 and particularly those near their terminal limits. For such 

 he will be glad to return the rarer British species, which 

 may be desiderata to any botanist favouring him with the 

 former.
