A430 HYPERTROPHY OF THE 
Toulouse. The same learned author also alludes to 
the so-called double Composites, viz. those in which 
the usually tubular florets of the disc assume the form 
and proportions of those of the ray, but these are 
hardly cases of hypertrophy. 
Enlargement of the andrecium—Dunal* alludes to a 
curious instance in a species of Verbascum, the lower 
flowers of which had hairy stamens as usual, but the 
filaments of the topmost flower were quite destitute of 
hairs, and dilated like a flat ribbon. 
Moquin relates having found in the neighbourhood 
of Toulouse a plant of Solanwm Duleamara in which 
all the upper flowers had two or three stamens of larger 
dimensions than the others. This happens habitually 
in Solanum tridynamum and S. Amazonicum, and to a 
less extent in S. vespertilio and S. cornutum; also m 
some species of Hyoscyamus. ‘These cases show the 
close affinity between the Solanacee and the Scrophu- 
lariacee. 
Enlargement of the gynecium.—In some flowers which 
have become accidentally female the pistil becomes 
unusually large, and even to such an extent as to pre- 
vent the passage of the pollen. Moquin remarks having 
seen this enlargement in the pistils of Sueda fruticosa 
and Kochia scoparia. The flowers of these Chenopods, 
under these circumstances, resemble the female flowers 
of some nettles. The styles of Anemone are also much 
enlarged as the result of cultivation, and from their 
petaloid appearance resemble those of the [vis (Goethe). 
MM. Seringe and Heyland’ have figured some anomalous 
flowers of Diplotawis tenwifolia in which the pistil, more 
or less distended and deformed, was considerably elon- 
gated below, so that it seemed to be borne upon a long 
stalk, analogous to that of fruits of Capparids. Dr. 
Klinsman’ mentions an instance of a similar kind com-
