this cause, it does not survive beyond two years. The 

 best method of cultivating it is found to be in cold damp 

 soil under a wall. It will not live in peat or light soil. 



That this is the same as Dillenius formerly cultivated 

 at Eltham, and as was afterwards published by Sir James 

 Smith from specimens obtained from Mr. Lee's Nursery, 

 we do not at all doubt. We have examined the Smithian 

 Herbarium in the possession of the Linnaean Society, and 

 the fragments therein preserved are clearly the same as 

 the plant now figured. Mr. Douglas is, however, of 

 opinion that his North-west plant is different from that 

 of Carolina. 



With regard to its genus, it has been referred by Linnaeus 

 to Polemonium, by Willdenow to Cantua, by Persoon, 

 whom Mr. Douglas follows, to Gilia, and by Michaux to 

 a particular genus called Ipomopsis. The idea of its being 

 a Polemonium has been long abandoned ; Cantua differs 

 essentially in its calyx and seeds ; and Gilia is a genus 

 founded in the Flora Peruviana upon plants with small 

 flowers, of which the stamens are inserted into the recesses 

 of the limb of the corolla, and of which Gilia capitata, now 

 common in our Gardens, is a legitimate species. To none 

 of these, therefore, can this plant be properly referred. 

 Ipomopsis must, therefore, be retained as a genus charac- 

 terised by the form of its corolla, the absence of foliaceous 

 involucrating bracteae, and the insertion of its stamens.
