new form, called Gloxinia x Fyfeana. It was remarkable in 
having the flowers erect and regularly shaped, and possessing 
five stamens, instead of the usual four. Hence this was a rever- 
sion to the ancestral and regular form of Gloxinia, not now known 
to exist in nature. 
The terminal flowers of Delphinium, Foxglove (Digitalis), 
and Horse Chestnut were mentioned as further examples of 
accidental returns to regularity in the midst of irregularity. 
In the Toad Flax (Linaria) the irregular personate corollas with 
four stamens were frequently changed into a regular flower with 
five stamens. In the irregular forms there is one spur, but in 
the regular one there are five fully developed, thus forming what 
is termed a ijcloria. 
Both these forms of Linaria were exhibited. A difference 
must be noticed in cases of true peloria from a true reversion 
to regularity, for in the former case the regularity is acquired by 
every petal assuming the same form as that of the one which 
usually only deviates from the rest ; so that the irregularity spreads, 
so to say, all round until all five petals are alike and the corolla 
becomes regular. In a true reversion the irregularity is lost by 
the non-development of the peculiarity. Thus in Columbines 
every petal has a spur ; consequently the flower is regular, but it 
resembles the pelorian state of Linaria. It often happens, how- 
ever, that all the spurs are suppressed, and the Columbine then 
has five leaf-like petals, and so exhibits a true reversion. 
The " doubling " of flowers was also referred to as a remark- 
able process in flowers. In many cases, e.g. the Rose, Carnation, 
Pink, Paeony, Buttercup, &c., the doubling was caused at the 
expense of the stamens and carpels, which are replaced by petals 
these latter being then greatly multiplied ; but in others, e.g. 
Campanula, it was caused by multiplication of the corolla alone, 
with or without a metamorphosis of the green calyx into a 
coloured one. The " Cup and Saucer " Campanula on the table 
was referred to as illustrating the point.
