SOME REMARKS ON MALFORMED FLOWERS. 109 
of the perianth, as seen in single flowers of -A^. major and other species, 
is accounted for by the fact that, in such cases, the segments of the 
corona are two-lobed, each lobe corresponding to the half of an anther, 
while the notch separating the two lobes of a single segment is deeper 
than the cleft between two contiguous segments.

REMAEKS ON SOME MALFOKMED FLOWERS OBSERVED 
BY MR. W, G, SMITH. 
By M. T. Masters, M.D., F.L.S. 
(Plate XXYIII., T'ig. 9-12.) 
I am indebted to Mr. W. G. Smith for tlie examination of some 
beautiful drawings iUustrative of various malformed flowers observed 
by that gentleman. Amongst them is a series representing various 
changes of an interesting nature in the flowers of Campanula Medium 
(Fig. 9, 10, 11). In most of them the calyx is unchanged, and consists 
of five' green, erect, ovate-lanceolate segments, between each pair of 
which hang down those tongue-shaped lobes or appendages, which give 
so peculiar an appearance to the calyx of this plant. The two sides 
of the reflected lobe belong to two different sepals, so that the lobe 
is a compound organ resulting from the union of the auricles of two 
adjoining sepals. This view is supported by one of Mr. Smith's speci- 
mens, wherein some of the erect calyx-lobes are deficient, while the 
auricular appendages are divided into their constituent pieces.
