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.[2][3][4][5]
Taxonomy
The genus Stenocarpus was first formally described in 1810 by Robert Brown in the Transactions of the Linnean Society of London.[6][7] The name Stenocarpus means "narrow fruit", referring to the long follicles of most species.
