In Aconitum the completely free median petals are less con- spicuous and are borne on long slender stalks and hidden in the large hooded dorsal sepal. In both genera there are usually three carpels which are free, but the Consolida section of Delphinium has only one. The fruit in the Helleboreae is generally a follicle containing few to many seeds; the single carpel of Adam forms a many-seeded. e, endosperm; c, cotyledons; r, radicle. F. Leaf. (A, B after Eichler.) (From Flor. Jam.) indehiscent berry. In Xanthorrhiza the carpels contain a pair of ovules, and the fruit is a one-seeded pod. In Nigella the carpels are more or less united and in N. damascena (Love-in-a-Mist) the fruit forms a septicidal capsule which has large hollow spaces be- tween the inner and outer layers of the pericarp. Tribe 2. Anemoneae. The flowers in this tribe are all actino- morphic and suggest a more primitive type than the Helleboreae. They have not, however, been so exhaustively studied as has the latter tribe. We may distinguish several groups. The first com- prises Anemone, herbaceous plants, rarely shrubb}^ with palmately.
