Stenocarpus
''Stenocarpus'' is a genus of about 22 species of flowering plants in the family Proteaceae. They are trees or shrubs with variably-shaped leaves, zygomorphic, bisexual flowers, the floral tube opening on the lower side before separating into four parts, followed by fruit that is usually a narrow oblong or cylindrical follicle. Description Plants in the genus ''Stenocarpus'' are trees or shrubs with leaves that may be simple, compound or lobed, depending on the species. The flowers are arranged in umbels or racemes at or near the ends of branches and are zygomorphic and bisexual. Four tepals form a flower tube that opens on the lower side at first before separating into four with a spherical end, there are four sessile anthers, the single carpel is stalked and the pollen presenter is an oblique, flattened disc. The fruit is a follicle that usually opens by splitting down one side and contains up to fifty seeds. Taxonomy The genus ''Stenocarpus'' was first formally desc ...

Stenocarpus Sinuatus
''Stenocarpus sinuatus'', known as the firewheel tree, is an Australian rainforest tree in the family Proteaceae. The range of natural distribution is in various rainforest types from the Nambucca River (30° S) in New South Wales to the Atherton Tableland (17° S) in tropical Queensland. ''Stenocarpus sinuatus'' is widely planted as an ornamental tree in other parts of Australia and in different parts of the world. Other common names include the white beefwood, Queensland firewheel tree, tulip flower, white oak and white silky oak. Description A medium to large tree, up to 40 metres tall and 75 cm in trunk diameter. The bark is greyish brown, not smooth and irregular. The base of the cylindrical trunk is flanged.

Pollen Presenter
A pollen-presenter is an area on the tip of the style in flowers of plants of the family Proteaceae on which the anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination Self-pollination is a form of pollination in which pollen from the same plant arrives at the Stigma (botany), stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen i .... References * Plant anatomy + Proteaceae {{Botany-stub ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'' and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...
