430 UYPERTROPUY 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 androecium. 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 Sohmum Dulcamara in which 

 all the upper flowers had two or three stamens of larger 

 dimensions than the others. This happens habitually 

 in Solanum tridynamum and 8. Amazonlcum^ and to a 

 less extent in 8. vespertilio and 8. comutum; also in 

 some species of Hyoscyamus. These cases show the 

 close affinity between the 8olanacem and the 8crojjhu- 

 lariacece. 



Enlargement of the gyncecinm. 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 8i(aHlafrutico8a 

 and Koelila 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 Iris (Goethe). 

 MM. Seringe and Heyland^ have figured some anomalous 

 flowers of Diplotaxis tenuifoUa 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-
