For one, both male and female cycads are gymnosperms and bear cones (strobili), while palms are angiosperms and so flower and bear fruit. The mature foliage looks very similar between both groups, but the young emerging leaves of a cycad resemble a fiddlehead fern before they unfold and take their place in the rosette, while the leaves of palms ...

One difference between the glans penis and the glans clitoridis is that the glans clitoridis packs nerve endings into a volume only about one-tenth the size of the glans penis. Therefore, the glans clitoridis has greater variability in cutaneous corpuscular receptor density (1-14 per 100× high-powered field) compared with the glans penis (1-3 ...
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.
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 ...
Encephalartos lehmannii is a low-growing palm-like cycad in the family Zamiaceae.It is commonly known as the Karoo cycad and is endemic to South Africa. [3] The species name lehmannii commemorates Prof J.G.C. Lehmann, a German botanist who studied the cycads and published a book on them in 1834. [3]
The male external genitalia have been used widely to aid in distinguishing species, whereas the female external genitalia may be simpler and less varied. The terminalia of adult female insects include internal structures for receiving the male copulatory organ and his spermatozoa and external structures used for oviposition (egg-laying; section ...
The gymnosperms (/ ˈ dʒ ɪ m n ə ˌ s p ɜːr m z,-n oʊ-/ ⓘ nə-spurmz, -noh-; lit. ' revealed seeds ') are a group of woody, perennial seed-producing plants, typically lacking the protective outer covering which surrounds the seeds in flowering plants, that include conifers, cycads, Ginkgo, and gnetophytes, forming the clade Gymnospermae [2] The term gymnosperm comes from the ...
