This elegant plant was sent for figuring by Mr. Bull, of 

 Chelsea, with whom it flowered in November, 1866, and to 

 whom the Royal Gardens are further indebted for a living 

 plant that has also flowered. The plant is no doubt a native 

 of Peru, whence most of its congeners have been brought, 

 and it is evidently (if any dependence is to be placed on 

 descriptions) the 8 Humboldtianus, DC, of which, however, 

 I have seen no authentic specimens; it also approaches S. 

 Peruvianus, but is larger in all its parts, has broader leaves 

 and pubescent stems, and different calyx-lobes. The genus 

 /Siphocampylus is very nearly allied to Lobelia, and like it, 

 abounds in showy flowered plants. Upwards of fifty species 

 have been described, of which scarce a dozen have been in- 

 troduced into our gardens. Some are climbers, and. coming 



march 1st, 1867.
