examples of T. hybridum in a clover-field between the church 

 and Ribble downs. We might have seen more if we had looked 

 for them ; but as we were in quest of more interesting plants 

 than cultivated Trefoils, we did not delay in the clover-field. 



To use the nomenclature of geographical botany, the plant 

 in question may take rank, if this can be called rank, among the 

 casual stragglers which have a very uncertain and limited distri- 

 bution through cultivation ; but it will be yet perhaps centuries 

 before it is dignified with the honoured name of colonist, denizen, 

 or some one or other of the names of the numerous categories 

 invented by phytogeographers. 



It is at least a century since this species claimed and ob- 

 tained a charitable notice from the father of British systematic 

 botany ; how many hundreds or thousands of years must elapse 

 ere it is entitled to take rank in some one or other of the 

 above named or implied classes ? 



Let botanical geographers answer this question, if they can.

Campanula rotundifolia. By F. Y. Brocas, Botanist. 



This form of the commonest of our Campanulas abounds by 

 the roadsides about Horsham, in Sussex, and as it grows every- 

 where in the above-said places, it is unnecessary to enter its 

 special localities. 



The root of this variety is very large, with a well developed 

 crown ; the latter is furnished with a more than usually nume- 

 rous tuft of radical leaves on long filiform petioles. These root- 

 leaves are cordate at the base, lobed or toothed, of all sizes, from 

 one-tenth of an inch to an inch in diameter. The stem-leaves 

 are like those of the common form. 



The stems are stout and branched, but not at all like those of 

 C. patula, nor like any other Campanula of British growth except 

 C. rotundifolia. They are from two to four feet high, with nume- 

 rous long slender branches which bear a multitude of flowers. 



The prominent difference between the Horsham plant and the 

 common form consists in the numerous radical leaves, the tall 

 slender stems, and the panicled flowers. 



In ' Historia Plantarum ' of the celebrated Clusius there is the 

 following description of a plant called by him Campanula minor,
