Cryptocarya rigida
Template:Short description Template:Speciesbox
Cryptocarya rigida, commonly known as rose maple, southern maple, rose walnut, pigeonberry ash, forest maple or brown beech,[1] is a species of flowering plant in the family Lauraceae and is endemic to eastern Australia. It is a shrub or small tree with lance-shaped to egg-shaped leaves, creamy green flowers, and elliptic black drupes.
Description
Cryptocarya rigida is a shrub or small tree that typically grows to a height of Template:Cvt with a dbh of about Template:Cvt and has grey, thin corky bark, it stems not buttressed. Its leaves are lance-shaped to elliptic, Template:Cvt long and Template:Cvt wide, covered with soft hairs, and glaucous on the lower surface. The flowers are usually arranged in panicles in leaf axils and shorter than the leaves. They are creamy-green, not perfumed, the perianth tube Template:Cvt long and Template:Cvt wide. The tepals are Template:Cvt long and Template:Cvt wide, the outer anthers about Template:Cvt long and Template:Cvt wide, the inner anthers Template:Cvt long and Template:Cvt wide. Flowering occurs from October to March, and the fruit is an elliptic black drupe, Template:Cvt long and Template:Cvt wide with creamy cotyledons.[1][2][3]
Taxonomy
Cryptocarya rigida was first formally described in 1864 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected near the Clarence River by Ferdinand von Mueller.[4][5] The specific epithet (rigida) means 'rigid'.[6]
Distribution and habitat
This species of Cryptocarya grows in rainforest, especially near the edges of rainforest, at altitudes between Template:Cvt from near Springbrook in southern Queensland to Dungog and Ourimbah in New South Wales.[1]
The species is extinct in the Illawarra region (34° S), allegedly seen there in 1818 by Allan Cunningham.[7]
Use in horticulture
Like most Australian species of Cryptocarya, removal of the fleshy aril is advised to assist seed germination, which is slow but reliable with C. rigida.
