I. BANUNCULACEiE 
Erect herbs. Leaves deeply lobed. Flowers irregular, racemed. 
Sepals 5, petal-like, free, the upper one produced at the base in the 
form of a spur, the others flat. Petals 4, the two upper each pro- 
duced at the base into a tubular spur enclosed within the spur of the 
sepal, limb small ; the two lateral petals flat, clawed, limb smaller 
than the sepals. Stamens many, filaments flattened at the base, 
tapering upwards. Ovaries 3, sessile, many-ovuled, style short, 
curved. Follicles many-seeded, tipped with the persistent styles. 
Honey is secreted in the spurs of the two upper petals, and can be obtained 
only by insects having a long proboscis, such as humble bees. In young flowers 
the stamens are so placed that a bee’s head rubs against the anthers ; in older 
flowers the stamens have withered and the stigmas then stand in the way of 
the bee’s head.
