Cycads / ˈ s aɪ k æ d z / are seed plants that typically have a stout and woody trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall.
E. woodii is dioecious, meaning it has separate male and female plants; however, no female plant has ever been discovered. The male strobili are cylindrical, 20–40 centimetres (7.9–16 in) long, exceptionally up to 120 centimetres (47 in), and 15–25 centimetres (6–10 in) in diameter; they are a vivid yellow-orange colour. A single plant ...
The Natal cycad is dioecious, having male and female cones on separate plants. The male cones are velvety and about 45 by 11 cm (18 by 4 in) in size. Pollen is produced from April to June. The two or three female cones are slightly woolly, yellowish-green and cylindrical, 55 by 25 cm (22 by 10 in) in size, the scales being covered with small knobs.
Male plants of E. whitelockii produce up to five, pendulous, bluish-green cones per stem, while female plants produce up to three, bluish-green egg-shaped cones. E. whitelockii is a long-lived, slow growing plant that always occur as individual male or female plants. There is no way of determining the sex of a cycad until it begins to produce ...
Cycads are dioecious, meaning that there are separate male and female plants, and the female produces seeds while the male produces pollen. Plants of this taxon have generally been considered to be wind pollinated, but several recent studies suggest that insect pollination is more likely. The seeds produced are typically large with a hard ...
Male cone Female cones Female cone, Yercaud, Tamil Nadu. Female cone of E. ferox subsp. ferox at Gage Park Tropical Greenhouse in Hamilton, Ontario. E. ferox is reported to grow relatively fast compared to members of other cycad genera, but are considered slow-growing when compared to other orders and classes. [3]
This species is dioecious, meaning it has separate male and female plants. The male cones are spindle-shaped, yellow, and measure 8–23 cm long and 3–5 cm in diameter. They have broad, rhombic-shaped microsporophylls. The female cones are ovoid, green, and larger, measuring 15–35 cm long and 8–15 cm in diameter.
The plant is dioecious, meaning it has separate male and female specimens. Male specimens have 1-3 green ovoid cones that are 18–25 cm long and 6–8 cm in diameter with green to silvery color. [4] Female specimens have 1-2 oval cones of the same color, which are larger at 30–35 cm long and 12 cm in diameter. In Bothalia both male and ...
