452 REPORT OF THE CONFERENCE ON GENETICS. 
last, as its name implies, is remarkable for its fine perfume. I think that 
as the newer varieties of this group become more widely known, their 
fine decorative qualities will receive wider recognition, and the thanks of 
rosarians are due to Monsieur Gravereaux of Paris for directing attention 
to this section. 
Probably no class of rose is more in evidence in gardens at the present 
time than the strong-growing varieties known as ‘Rambler’ roses. 
These owe their popularity as well as their current appellation to the 
‘Crimson Rambler,’ a variety of Rosa multiflora, which reached our 
shores from Japan, unheralded and unknown, about twenty years ago, and 
had already been in cultivation here for several years and under more 
than one name before its merits were finally demonstrated in the Slough 
nursery, where the magnificent effect of the established plants in full 
bloom procured for them the honour of a visit from her late Majesty 
Queen Victoria. I have never seen the parentage of this variety stated 
with authority, and it is probably unknown, but it was easy to foresee 
from the first that hybridisers would soon attempt to obtain counterparts 
of it in other shades of colour. The first to reach us were the yellow, 
pink, and white ‘Ramblers’ from Germany known as ‘ Aglaia,’ ‘ Kuphro- 
syne,’ and ‘Thalia,’ raised from the type 2. multiflora crossed with ‘ Réve 
d'Or,’ ‘Mignonette,’ and ‘Paquerette’ respectively, and which are still 
valuable climbing roses. Many other seedlings of varying degrees of 
excellence, and with both single and double flowers, have been raised 
and introduced since; some the result of natural fertilisation, others 
by hybridising or cross-breeding, R. Wichuraiana either as pollen or 
seed-bearer having been employed with good effect in some instances. 
Some of the best and most distinct of these may be particularised as 
follows : 
‘Blush Rambler ’—semi-double pink flowers. Parentage not stated. 
‘Débutante ’—pale pink, distinct both in foliage and form of truss. 
Parentage not stated. 
‘Gruss an Zabern’—‘ Euphrosyne’ x Tea ‘Mme. Ocker Ferenez’ ; 
double white, habit not quite so vigorous as others of the section. 
‘Héléne ’—(H.T. x ‘ Aglaia’) x ‘Crimson Rambler.’ 
‘Hiawatha ’—a seedling from ‘Crimson Rambler,’ other parent not 
stated ; single flowers, crimson with white eye. 
‘Kathleen ’—‘ Crimson Rambler’ x ‘Félicité Perpétue;’ single 
flowers, rosy-red with white eye. 
‘Leuchtstern ’—a seedling from ‘Crimson Rambler ;’ single flowers, 
pink with white eye. ; 
‘Non Plus Ultra’—a dark crimson form of ‘Crimson Rambler’ 
obtained by crossing this variety with the dwarf Polyantha 
‘Blanche Rebatel.’ 
‘ Philadelphia Rambler ’—‘ Crimson Rambler’ x H.P. ‘ Victor Hugo’ ; 
a brilliantly coloured form, but the flowers are produced singly or 
in small clusters. 
‘Psyche ’—‘ Crimson Rambler’ x Dwarf Polyantha ‘ Golden Fairy.’ ~ 
‘Rubin ’—fine brilliant red. Parentage not stated. 
‘Trier ’—‘ Aglaia’ x H.P. ‘Mrs. Sharman Crawford’; double white 
flowers; blooms in autumn.
