422 MR. W. AND MISS A. BATESON ON FLORAL VARIATIONS 
In Veronica Buxbaumii 3-petalled flowers are common on all 
soils and in many gardens round Cambridge, though entirely absent 
in a few localities according to our experience. This type most 
frequently has 4 sepals, but 3-sepalled specimens are not rare. 
Flowers with 5 petals having the form either of No. 1 or No. 2 
are also fairly common, especially in gardens. Speaking gene- 
rally, there are in garden soil not less than 1 per cent. of each of 
these forms in many localities. Several forms of asymmetrical 
corollas have been seen, but they are rare and are generally 
associated with petalody of stamens. The latter phenomenon is 
rare, and is seen especially in the case of certain dwarfed corollas 
which are sometimes found. These curious flowers are very in- 
teresting, but cannot be satisfactorily described in so short a 
note. 
In the Cambridge Botanic Garden the two kinds of 5-petalled 
flowers are very common on F. austriaca, V. rupestris, and V. pec- 
tinata. In the pateh of the last-named form at the Gardens 
abnormal flowers are as frequent as normal ones, and about a 
quarter have petalody of one or both stamens or other complex 
malformations. *Synanthy " is also common in this form. 
On V. Chamedrys two flowers of the 3-petalled type were 
seen this year on separate plants. The 5-petalled form of flower 
with two posterior petals also was found sparely. Abnormal 
flowers in this species appear to be decidedly rare.

3. Flower having corolla normally divided, but with two spurs I instead of 
one (and five complete stamens). : 
4. Flower intermediate between that shown in fig. 3 and that shown in 
fig. 5 (rare). 
5, Abnormal flower, No. 2 (in text). 
6. Abnormal flower, similar to that shown in fig. 5, but having three spurs 
instead of two. i 
7. Abnormal flower, having one posterior petal and five anterior ones— $!x 
in all. 
In figs. 5, 6, and 7 the anterior sepal is not shown.
