- Аннотация: All Illicium spp. have explosive fruits, which is a unique character among the basal grade of angiosperms. Illiciumfruits consist of several ventrally dehiscing follicles developing from conduplicate carpels, with a prominent,slightly postgenitally fused ventral slit. The closure of the ventral slit is also secured by two mirror-symmetricalmassive longitudinal sclerenchymatous bands in the mesocarp along the edges and by turgor pressure. Thepericarp differentiates into a fleshy (or coriaceous) peripheral zone (exocarp and mesocarp) with numerousethereal-oil-containing cells and a sclerenchymatous (single-layered, palisade) inner zone (endocarp). Dehydrationof the fleshy zone of the pericarp and partial compression of the epidermal sclereids with U-shaped wall thickeningslining the ventral suture are instrumental in explosive fruitlet dehiscence. Generally, the fruit structure of Illiciumdiffers dramatically from those in other early diverging angiosperms. Gynoecium and fruit structure (and aprobable early Cretaceous divergence from the Schisandra-Kadsura clade) provide evidence for treatment ofIllicium as separate from Schisandraceae s.s.
