 locality, date and name of communicant. 



Thirdly. Perfect specimens, in a recent state, if possible, must be 

 transmitted to Devonshire Street for the purpose of being drawn, or 

 for comparison with drawings accompanying them. Drawings made 

 by the communicant will be preferred, and magnified details of diag- 

 nostic characters, where the new plant resembles a generally known 

 species, will be acceptable. 



Fourthly. A careful description must accompany the drawings, 

 &c. : if the plant be new to science this, of course, must be original, 

 but if previously known as a continental species, a translation from a 

 standard author will suffice. 



I sincerely hope that British botanists will see the great utility of 

 this project, and will cheerfully and heartily co-operate with me in 

 carrying it into execution. I have already received such manifest 

 proofs of kindness and goodwill from my contributors that I feel no 

 hesitation in again soliciting their assistance : an additional ex- 

 pense will now be incurred, and this can, I think, be readily defrayed 

 by an increased sale : a larger number of copies will be prepared, 

 and the exertions of my friends are most earnestly requested in the 

 obtaining of additional subscribers. 



In looking back on the past year, it does not occupy a prominent 

 place in the botanical annals of the country. Beyond sundry pro- 

 posed subdivisions and changes of name, thus imparting a superficial 

 idea of novelty, the botanical additions for the year 1849 have been 

 very few. 



Poterium muricatum of Spach, the P. polygamum of Waldstein, 

 has been found (Phytol. iii. 707) by several botanists near 

 Cambridge ; my valued correspondent, Mr. G. S. Gibson, 

 subsequently met with it at Heydon, in Essex, and at Box- 

 hill, in Surrey ; and Mr. Kirk (Phytol. iii. 715) has found it 

 in various places on the slopes of the Coventry and Leaming- 

 ton railway, in Warwickshire. This plant is to be regarded 

 as an old and probably not uncommon inhabitant of this
