 are like those of Campanula minor, which grows in several parts 

 of Belgium and Germany, in open places and under bushes in 

 woody places, and about the borders of fields. 



TerresMal Orchids. By John Lloyd. 



Among botanical cultivators it is a generally received opinion 

 that any plant may be successfully cultivated if the condition 

 under which it exists in a natural state can be made applicable 

 to it under cultivation. The Terrestrial Orchids have long been 

 especial favourites with the botanist, and many attempts have 

 ^een made to bring them under cultivation, but hitherto with 

 very partial success, the cause of which I take to be is that the 

 periodicity of the plants has not been taken into consideration 

 by those who have attempted to cultivate them. 



The period of duration of our British species varies from two 

 to five years ; the Bird's-nest and the Twayblade may be cited as 

 examples of the former, Avhilst the palmate species may be taken 

 as examples of the latter. It should also be borne in mind that 

 no increase can ever be expected from parting of the roots, as 

 they never produce offsets ; and as to the fact of a bunch being 

 sometimes found growing together, that is easily accounted for
