one would expect to find is five, for there are five sepals and 
five petals. Mullein has five stamens ; Figwort four and a stami- 
node ; Veronica two only. Com- 
paring Veronica (Figs. 125 and 
126) with a typical scrophulari- 
aceous flower (Fig. 124), we note 
that the anterior petal is the 
smallest ; the posterior probably

ones. 
This Order is also characterised by its variety of corolla ; 
often it is two-lipped, as in Figwort, Cow-wheat, Rattles, 
Bartsia, Snapdragon, Toadflax, Foxglove, Eyebright. In. 
Veronicas and Mulleins it is rotate ; Toadflax is spurred. 
Many are semi-parasitic plants, having green leaves, but
