CROSSINGS MADE AT NATURAL HISTORY MUSEUM, PARIS. 225 
The object sought for (change of colour of the flower) has therefore 
been obtained in as satisfactory a manner as possible, whilst preserving 
the habit of growth of the Bretschneider Lilac. 
2. Syringa Josikzwa (Jacq.) xS. Bretschneideri (Hori.). 
From crosses made in 1890 I have obtained thirty-two plants, which 
have commenced to flower in 1897. 
The result has turned out fairly the same as in the inverse cross (see 
above). In comparing, however, the two results it may be noted that 
in this cross :—The leaves are longer, with more attenuated points, and 
less hairy, sometimes altogether glabrous. The inflorescences are 
narrower and a little less furnished; the rachis is of darker colour. The 
buds are redder, and the divisions of the flowers wider open and more 
recurved. The flowers also present more red, and some of the plants 
have them of a very striking purplish colour. 
To sum up, in the two cases, the influence of the parents may be 
thus specified :—S. Bretschneiderit shows itself particularly in the habit 
of growth, the stems, the leaves, and the shape of the inflorescence. 
The influence of S. Josikea is seen most in the shape of flower, its 
colour, form, and dimensions. 
3. Syringa Bretschneideri (Hort.) x Syringa vulgaris (L.). 
Object.—To obtain new colours in‘the Bretschneider Lilac, an agree- 
able scent, and an earlier flowering. (The Bretschneider Lilac is pink, 
has a smell resembling that of Privet, and flowers twelve days later 
than the Common Lilac.) Numerous and repeated attempts were made, 
at first taking pollen from single-flowered varieties, and then from double- 
flowered ones. 
(a) Crosses with single-flowered varieties. 
1890. Eleven inflorescences treated. Five gave seed, none 
germinated. 
1893. Five inflorescences treated. ‘Two yielded seed, which gave 
one plant. 
1894. Four inflorescences treated. Two yielded seed, which gave 
ten plants. One of these plants flowered in 1899 a lovely pink. (The 
variety which furnished the pollen used to obtain this plant is 
the Lilac ‘ Charles X.’) 
1895. Three inflorescences treated. One yielded seed, which gave 
two plants. 
1896. Five inflorescences treated. One seed gathered, gave one 
plant. 
1897. Three inflorescences treated. Two yielded seed, which gave 
fourteen plants. 
1899. One inflorescence treated. Two fruits appeared to be good 
on July 4, 1899. 
(b) Crosses with double-flowered varieties. 
1894." One inflorescence treated. Four seeds obtained, not 
germinated,
