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 5 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 whom 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.
