VARIEGATED FOLIAGE AND DOUBLE FLOWERS NOT 
OCCURRING TOGETHER. 
Professor E. Morren maintains that variegated foliage and double 
flowers never occur together on the same plant. He explains the fact 
that variegated leaves (the partial disappearance of chlorophyll) is a 
proof of weakness, whilst doubling of flowers is a proof of strength, 
and as both these conditions cannot possibly occur at the same time, 
variegated leaves and double flowers on one and the same plant are 
an impossibility. Bull’s variegated Camellia Japonica, figured in our 
last number (tab. 42), is a case in point. Whilst all other Camellia 
Japonicas of our gardens have green leaves, and either double or semi- 
double, but never single flowers, this variegated kind has flowers with 
the five normal petals only. An apparent exception to P 
hypothesis is presented by Kerria Japonica. Of this plant two varieties 
have recently been introduced into our gardens, but it is suspected that 
plate 336 of the Illustr. Horticole, on Which they are figured, was made 
up by the artist taking the varieties with variegated leaves, and sticking 
on to them the double flowers of the ordinary green-leaved variety.—

Dr. de Bary commences with a recapitulation of his former observa- 
tions (Ann. des Sc. Nat. xx. P. 1), which were directed to show that 
certain species of Uromyces and Puccinia exhibit five different sorts of 
reproductive organs, These organs are, first, spores, or as the author 
proposes to call them, teleutospores, which germinate and produce what 
has been called a promyceliwm, upon which the second kind of repro- 
ductive organ, viz. the sporidia, are borne. The sporidia germinate and
