ADEXOPHOR.V VERTICILIATA. 115 



not quite unattainable, they are very rare. All are natives of California and the 

 frontier between Mexico and that province. The species figured is not expensive, 

 at least when its rarity is considered ; from 2s. to 2s. 6^. will purchase a bulb. 



Cijcloboihra is derived from hjUos, a circle, and bothros, a well or pit, in reference 

 to the nectary occurring on each petal. 



ADENOPHORA VERTICILLATA. 



JFTiorl-leaved Adenophora. 

 linnean Class — Pentanduia. Order — Monogynia. Natural Order — Campantjlaceje. 



Oue readers will hardly need to be apprised of the relationship of the plant to 

 which we now direct their attention, for it presents unmistakeable evidence 

 of belonging to the family of Bell-worts. The genus Adenophora was, indeed, 

 formerly included with the true Campanulas, but has been separated from 

 tbem by Dr. Fischer on grounds which we will briefly state. 



The leading features of the genus Campanula have already been pointed 

 out at page 136 of Vol. I, and it will therefore be sufficient to observe 

 that the Adenophoras differ chiefly in the presence of a curious cylinder 

 or annular gland, varying in size in the different species, which surrounds 

 the base of the style. In some of the species it is inconspicuous and of 

 a membranous character, as in coronopifolia ; but in others it is quite 

 fleshy, and, in the case of A. verticillata and A. latifolia, from one-sixteenth to 

 one-eighth of an inch in length. This glandular body is concealed beneath 

 the dilated filaments, which connive closely at their base, as in the genus 

 Campanula. If to this evident distinction we add that, in Adenophora, 

 the style usually projects beyond the mouth of the flower to a greater 

 de"Tee, and is much more attenuated at its base than in Campanula, and 

 that the seeds of the former are much larger, we have named the only 

 differences between the two genera which are of any importance. The five- 

 chl't, superior, calyx and corolla; five stamens with their filaments 

 dilated at the base, and generally fringed with hairs; and the trifid stigma, 

 are common to both. 



The latter organ is furnished with the same brush-like apparatus for collecting 

 and retaining the pollen, referred to under the head Campanula coronata, the 

 anthers discharging their contents whilst the flower is in bud, as in the allied
