454 REPORT OF THE CONFERENCE ON GENETICS. 
‘Gardenia,’ ditto x Tea ‘Perle des Jardins.’ 
‘Jersey Beauty,’ ditto x Tea ‘ Perle des Jardins,’ 
‘Pink Pearl,’ ditto x H.T. ‘ Meteor.’ 
‘Réné André,’ ditto x Noisette ‘ L’Idéal.’ 
‘ Wichuraiana rubra,’ ditto x ‘Crimson Rambler.’ 
‘Joseph Billiard,’ ditto x ‘Madame Eugéne Reésal.’ 
With the exception of Wichwraiana rubra, these will all be found to vary 
from the type (R. Wichuraiana) in flowering earlier in the summer, 
whilst, notwithstanding the crosses with autumnal-flowering varieties, 
none of them can be described as autumnal bloomers. 
My notes would not be complete without a reference to the hybridisa- 
tion of the sweet brier, which in the hands of the late Lord Penzance 
yielded some beautiful decorative forms, the early summer being their 
especial season for blooming. Mention should also be made of R. 
levigata, the ‘Camellia rose’ of the south of Kurope, already reputed to 
be one of the parents of the hybrid Banksian F'ortwneana, and which has 
given us of late years the beautiful single pink hybrid known as the 
‘Anemone rose’ (not to be confused with A. anemoneflora), which 
appears to be hardier than A. levigata. Attempts at fertilising flowers 
of the Anemone rose at Waltham Cross have hitherto failed to result in 
the production of seed. Some handsome single-flowered seedlings from 
R. macrantha—itself of hybrid origin—have also been recently added to 
the effective varieties of garden roses blooming in early summer. Of the 
many interesting crosses of other species and varieties of rcses now being 
carried out and tested in various botanic and private gardens and nurseries 
it is too early to speak from a horticultural point of view, as the results 
are not in general cultivation ; but it is reasonable to suppose that, when 
the time arrives for the next Conference of this Society on hybridisation 
and cross-breeding, substantial progress will have been recorded in the 
evolution of valuable new forms for the ornamentation of our gardens.
