Evergreen or shamel ash (Fraxinus uhdei), a beautiful ash tree native to Mexico and commonly planted in southern California. During the summer months it produces masses of slender, winged, one-seeded fruits (called samaras) that fly through the air like a squadron of miniature helicopters.

Ovulate (female) cone and winged seeds of mountain hemlock (Tsuga mertensiana). The winged helicopter seeds spin as they fall from the branches of this high elevation California cone-bearing tree.

Large inflorescence (left) and cone-like fruit cluster of Banksia media. Each seed capsule (follicle) opens and releases 2 winged helicopter seeds similar to those of cone-bearing gymnosperms. This remarkable Australian shrub belongs to the spectacular Protea Family (Proteaceae).

Woody seed capsules of the sea urchin tree (Hakea laurina). Each capsule opens and releases 2 winged seeds similar to those of cone-bearing trees. This interesting Australian shrub belongs to the Protea Family (Proteaceae).
