 P. grandiflora. Hooker in Bot. Mag. t. 3618. 

 P. gracilis. Bon fide Steudel. 



This pretty twining plant is a native of Buenos Ayres, or 

 rather of Tucuman, whence its seeds were originally sent to 

 the Glasgow and Glasnevin Botanic Gardens by Mr. Tweedie. 

 It varies a good deal in the colour of its flowers and in the 

 quantity of down that covers it ; in wild specimens it soon 

 becomes woolly ; but these differences do not appear to be 

 specific. In respect of colour, the variety now represented 

 and that with pale yellow flowers, in the Botanical Magazine, 

 may be taken as the two extremes. 



The Philibertia gracilis of the Gardens has been referred 

 to this species by Steudel, and with reason. It is clearly no 

 more than a variety of P. grandiflora. 



* J. C. Philibert, after wh^m this genus has been named, was the 

 author of an Introduction to Botany published in 1799, of a Botanical Dic- 

 tionary dated 1802, and of some other elementary books.
