450 REPORT OF THE CONFERENCE ON GENETICS, 
(the pollen-bearing parent not stated); ‘Richmond’ (H.T. ‘Lady 
Battersea’ x ‘ General Jacqueminot’) ; ‘ Kénigin Carola’ (H.T. ‘ Caroline 
Testout’ x H.T. ‘Viscountess Folkestone’); in the flowers of this 
variety the colour and characteristics of each parent are clearly dis- 
cernible; ‘Madame Jules Gravereaux’ (Noisette ‘Réve d’Or’ x H.T. 
‘Viscountess Folkestone’); ‘Etoile de France’ (H.T. ‘Madame Abel 
Chatenay’ x H.P. ‘Fisher Holmes’); ‘Madame Léon Pain’ (H.T. 
‘Caroline Testout’ x Tea ‘Souvenir de Catherine Guillot’) ; ‘ Billiard et 
Barré’ (H.T. ‘ Alice Furon’ x Climbing Tea ‘Duchesse d’Auerstaedt ’). 
In the case of M. Pernet-Ducher’s later series of Hybrid Tea roses which 
include ‘Madame Ravary,’ ‘Le Progrés,’ ‘Prince de Bulgarie,’ ‘Joseph 
Hill,’ ‘Mélanie Soupert,’ ‘Marquise de Sinety,’ ‘Instituteur Sirdey,’ 
‘Paul Ledé,’ ‘Madame Philippe Rivoire,’ and others, I have seen no 
authoritative statement of the crosses employed, but I think we shall not 
be far wrong in assuming that the rich yellow and orange tones of colour 
in the flowers may be due to the direct or indirect employment of 
pollen from varieties of R. lutea. With the ever-increasing store of 
material available, there are surely possibilities of further distinct and 
valuable advances in the Hybrid Tea and Hybrid Perpetual classes. 
Although botanically closely allied, from a horticultural standpoint 
the Chinese or Bengal and the Tea-scented roses have been regarded as 
distinct classes; but of late years, by the crossing of varieties, we have 
obtained a class of Chinese roses which are approximating in size and 
form of flower as well as in shades of colouring to the Tea roses, whilst in 
the Tea section we have a new series of decorative varieties which combine 
the stronger habit of growth in the Tea roses with the excessive freedom 
of flowering of the Chinese. To the former category, which may be 
termed ‘Tea-Chinas,’ may be referred such varieties as ‘Madame 
Laurette Messimy,’ ‘Madame Eugéne Résal,’ ‘Irene Watts,’ ‘Queen 
Mab,’ ‘Aurore,’ ‘Comtesse de Cayla,’ and others, whilst to the latter, 
which may be termed ‘China-Teas,’ belong ‘Corallina,’ ‘Souvenir de 
Catherine Guillot,’ ‘Souvenir de J. B. Guillot,’ ‘Enchantress,’ and others 
possessing similar characteristics. All these are most valuable for 
garden ornamentation, especially in the late summer and early autumn 
months, and further distinct introductions will be most welcome. A new 
hybrid Chinese rose, possessing traits peculiar to itself, is ‘ Petrus 
Donzel’; in the colour of the flowers and the habit in which they are 
produced there appears to be some affinity with ‘Gruss an Teplitz,’ but 
the growth of the plant is not so vigorous. 
A remarkable example of the variations to be obtained by hybridisa- 
tion in voses is afforded by the dwarf-growing Polyantha or Multiflora 
roses now so largely used for massing and edging in gardens as well as 
for pot culture. This series commenced some years ago with ‘ Paquerette’ 
(Guillot), ‘Perle d’Or’ (Dubreuil), ‘Anne Marie de Montravel’ (Ram- 
baux), ‘Gloire des Polyantha’ and others, which were obtained by 
crossing R. multiflora (polyantha), a strong-growing summer-flowering 
species, with the dwarfer-growing R. indica or other autumnals, the 
result being quite a new class, possessing the floriferous habit and 
large corymbs of flowers of R. multiflora combined with the autumnal 
flowering qualities of the other parents and a dwarf and regular habit of
