Bowenia
The genus ''Bowenia'' includes two extant taxa, living and two fossil species of cycads in the family Stangeriaceae, sometimes placed in their own family Boweniaceae. They are entirely restricted to Australia. Description The chromosome count is 2n = 18. Species Distribution The two living species occur in Queensland. ''B. spectabilis'' grows in warm, wet, tropical rainforests, on protected slopes and near streams, primarily in the lowlands of the Wet Tropics of Queensland, Wet Tropics Bioregion. However, it has a local form with serrate pinna margins that grows in rainforest, ''Acacia''-dominated transition forest, and also ''Casuarina''-dominated sclerophyll forest on the Atherton Tableland, where it is subject to periodic bushfire. ''B. serrulata'' grows in sclerophyll forest and transition forest close to the Tropic of Capricorn. Fossils The fossil species ''Bowenia eocenica'' is known from deposits in a coal mine in Victoria, Australia, and ''B. papillosa'' is known fr ...

Bowenia Spectabilis
''Bowenia spectabilis'' is a species of cycad in the family Stangeriaceae. It is endemic to Queensland, Australia. Its natural habitat is subtropical or tropical moist lowland forests. Range ''Bowenia spectabilis'' is found in northeastern Queensland from the McIlwraith Range on the Cape York Peninsula south to near Tully. It is a rainforest species, growing close to streams and on sheltered slopes in lowland wet sclerophyll forest, but also at an altitude of up to 700 metres in the Atherton Tableland The Atherton Tableland is a fertile plateau, which is part of the Great Dividing Range in Queensland, Australia. It has very deep, rich basaltic soils and the main industry is agriculture. The principal river flowing across the plateau is the B .... Gallery The 1889 book 'The Useful Native Plants of Australia' records that the yam-like rhizome is used for food by the Indigenous Australians.

Bowenia Serrulata
''Bowenia serrulata'', the Byfield fern, is a cycad in the family Stangeriaceae. Its bipinnate fronds, arising from a subterranean caudex, give it the appearance of a fern. However it is not a fern as its vernacular name and appearance suggest. It is endemic to the vicinity of Byfield, Australia Australia, officially the Commonwealth of Australia, is a country comprising mainland Australia, the mainland of the Australia (continent), Australian continent, the island of Tasmania and list of islands of Australia, numerous smaller isl ....

Cycadophyta Of Australia
Cycads are seed plants that typically have a stout and woody (ligneous) 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. They typically grow slowly and have long lifespans. Because of their superficial resemblance to palms or ferns, they are sometimes mistaken for them, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific beetle, and more rarely a thrips or a moth. Both male and female cycads bear cones ( strobili), somewhat similar to conifer cones. Cycads have been repor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk (botany), trunk with a crown (botany), 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. They typically grow slowly and have long lifespans. Because of their superficial resemblance to Arecaceae, palms or ferns, they are sometimes mistaken for them, but they are not closely related to either group.

Stangeriaceae
The Zamiaceae are a family of cycads that are superficially palm or fern-like. They are divided into two subfamilies with eight genera and about 150 species in the tropical and subtropical regions of Africa, Australia and North and South America. The Zamiaceae, sometimes known as zamiads, are perennial, evergreen, and dioecious. They have subterranean to tall and erect, usually unbranched, cylindrical stems, and stems clad with persistent leaf bases (in Australian genera). Their leaves are simply pinnate, spirally arranged, and interspersed with cataphylls. The leaflets are sometimes dichotomously divided. The leaflets occur with several sub-parallel, dichotomously branching longitudinal veins; they lack a mid rib. Stomata occur either on both surfaces or undersurface only. Their roots have small secondary roots. The coralloid roots develop at the base of the stem at or below the soil surface. Male and female sporophylls are spirally aggregated into determinate cones that gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
