The Cytisus which forms the subject of our illustration is 
a hybrid raised at Kew in 1900. A plant of C. scoparius, 
Link, var. Andreana, Hort. (Genista Andreana, A. Puiss.), 
was isolated in a greenhouse and the flowers were fertilised 
with the pollen of the well-known White Portugal Broom, 
C. albus, Linn. There is thus no doubt as to its origin, and 
it may be remarked in passing that it is as yet the only 
hybrid broom intentionally produced, other hybrids being 
the result of chance crosses made by insects. Andreé’s 
Broom, now well known in gardens, was discovered in 
Normandy about thirty years ago; it differs from typical 
C. scoparius in having rich brown-crimson wing-petals, the 
rest of the flower being yellow asin thetype. The flowers of 
C. albus are milky-white, sometimes slightly tinged with rose. 
In C. Dallimorei the yellow of the female parent has almost 
disappeared and the whole flower has assumed some shade 
of rosy-purple, the wing-petals alone showing some approach 
to the rich colouring of the wings in Andreé’s Broom. Onl 4 
two seedlings were raised from the original cross—one wit 
Marcu, 1913.
