Gyrocarpus americanus is a slender, deciduous tree with smooth, grey bark. The tree grows to about 12 m in height. The leaves are spirally arranged, crowded near the ends of the branches, and grow up to 150 × 120 mm in size. They are ovate, often 3-lobed, dark green above, paler and greyer below, with velvety surfaces, 3-veined from the base ...
Like all Leucadendrons, this tree is dioecious, with separate male and female plants. The fruit is a heavy woody cone, containing numerous seeds ; each seed is a small nut with a silky-haired helicopter-like parachute, enabling it to disperse by wind.
Male flowers Seeds of Fraxinus excelsior, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara. It is a large deciduous tree growing to 12–18 m (39–59 ft) (exceptionally to 43 m or 141 ft) tall with a trunk up to 2 m (6.6 ft) (exceptionally to 3.5 m or 11 ft) diameter, with a tall, narrow crown.

The shape of a samara enables the wind to carry the seed further away from the tree than regular seeds would go, [3] and is thus a form of anemochory. In some cases the seed is in the centre of the wing, as in the elms (genus Ulmus ), the hoptree ( Ptelea trifoliata ), and the bushwillows (genus Combretum ).
The male cones are slender conic, 5–11 cm (2.0–4.3 in) long and 1–2 cm (0.39–0.79 in) broad and reddish-brown in colour and are lower on the tree than the seed cones. [3] Seedlings appear to be slow-growing [ 3 ] and mature trees are extremely long-lived; some of the older individuals today are estimated to be between 500 and 1,000 ...
The tree produces spiky green fruits about the size of a golf ball, which turn brown and drop off the tree over an extended period beginning in fall and continuing over the winter.
The capsules explode when ripe, splitting into segments and launching seeds at 70 m/s (250 km/h; 160 mph). [5] One source states that ripe capsules catapult their seeds as far as 100 m (330 ft). [9] [verification needed] Another source states that seeds are thrown as far as 45 m (150 ft) from a tree, with a mode of about 30 m (100 ft). [10]
