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 Linnsean 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 Linnzus 
to Polemonium, by Willdenow to Cantua, by Persoon, 
whom Mr. Douglas follows, to Gilia, and by Michaux to 
a Saba 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 bractez, and the insertion of its stamens.
