The other tran- sition genera re- ferred to are Astydamia, Pole- mannia, and Aci- phylla. Astyda- mia canariensis is a perennial whose fruit is that of a Peucedan, with wide solitary vittse in each furrow; but the mericarps have thick sub- erose margins which early sepa- rate from each other. The car- pophore unlines itself at maturity, and the vittae are wide and solitary in each furrow. The seeds have a flat or slightly concave surface. The embryo, with long lanceolate cotyledons, occupies about half the length of the albumen. Polemannia consists of types with small somewhat rounded fruit. The margin is thick and almost fleshy, and the base of the mericarp is decurrent on the pedicel. They are Cape shrubs whose full inflorescence bears simple lateral. Fig. 99. Flowering summit (j)..
