away, the equilibrium between the two lips must be restored. The 

 Peloria consists then of a whorl of leaves completely reduced 

 to corolla ; and exhibits spots all round the base, because all 

 round no stamens have come to perfection. Neither of the Pe- 

 loriae was terminal. The stalk of one was even so much grown 

 together for its whole length with the stalk of a completely normal 

 neighbouring flower, that the calyx of each stood with its back to 

 the other, and both the corollas were extended almost horizontally." 



" Linaria vulgaris. Monstrous flowers described by E. Heufler. 

 A very remarkable monstrosity, and deserving of notice because it is 

 out of the usual routine of metamorphoses. The upper lip of the 

 flower had nothing peculiar, beyond the i-udiment of a spur on the 

 dorsal surface. The lower lip was decidedly larger, and was in- 

 creased by one or two mis-shapen lobes ; the throat more swollen and 

 excessively wrinkled. The four stamens were changed into trumpet- 

 shaped tubes. Each individual tube stood out from the throat at a 

 different inclination. The lowest part was like a spur ; the middle 

 was set with orange-coloured hairs ; the uppermost part was again 

 smooth, and opened in the most various ways. The margin was 

 turned irregularly outwards, and in every single segment differently 

 formed. The rudiment of the fifth stamen had become a similar 

 tube-shaped leaf, which from the inner surface of the upper lip 

 was free, and projected beyond the flowers. This metamorphosed 

 fifth stamen was very delicately formed ; quite naked and transpa- 

 rent, of a dilute sulphur-yellow tint. Very often were traces of a 

 sixth and a seventh stamen present, either in the form of a transpa- 

 rent spiculum, or as a delicate pedicle, bearing a yellowish, leaf-hke 

 scale. Instead of the pistil, a second flower more or less developed 

 was present. From the description of this Peloria, we see that it is 

 no retrogradation from a normal flower, but an advance towards a 

 more highly developed form of inflorescence." 



Campanula persicifolia. — " The leaves of the plant constantly ap- 

 proximated more to the character of flowers as they reached the upper 

 part. The leaves of the stem, from the ninth to the thirteenth, had 

 their margins crisp and wavy ; from the thirteenth to the eighteenth 

 they had a blue colour ; from the nineteenth to the twenty-third the 

 leaves continually diminished in size, and were of a greenish blue, 

 very pale colour ; some were coherent by their margins. A whorl of 

 half-flower, half-leaf-like organs were developed, before the five ver- 

 ticillate stamens appeared. Each of these last bore at its upper and 

 anterior part a two-celled, well-developed anther, whose cells were
