위키 설명

 

Protea neriifolia, also known as the narrow-leaf sugarbush,[4][5][6] oleander-leaved sugarbush,[4] blue sugarbush,[4][7] or the oleanderleaf protea,[citation needed] is a flowering plant in the genus Protea,[6] which is endemic to South Africa.[4]

 

Common names for the species in the Afrikaans language include blousuikerbos,[7] baardsuikerbos,[4] baardsuikerkan,[4] blou-suikerbos,[4] blousuikerkan,[4] roosboom[4] and suikerbos.[4]

 

 

 

Taxonomy

Although it was first discovered by Europeans in 1597, and was the subject of a botanical illustration in 1605,[citation needed] the plant was first described as a distinct species according to the modern Linnaean system by the naturalist Robert Brown in his 1810 treatise On the Proteaceae of Jussieu.[2]

 

Description

It is a large, erect shrub or small tree,[6][7] growing from about three[6][9] to five metres in height.[9] The stems become glabrous (hairless) when mature.[7]

 

The leaves are 'sessile', which means they lack a petiole and arise straight from the stems. These leaves diagnostically curve upwards. They are elliptic-shaped, coloured green or blue-grey, and their margin run parallel to each other. The leaves become glabrous when mature.[7]

 

It blooms in Summer and Spring,[7] although it has also been seen blooming in the Winter and Autumn.[5] The plant is monoecious, with both sexes in each flower.[6] It has its flowers arranged in a flower head, a special type of inflorescence.[citation needed] Each branch bears only one inflorescence. This species is recognisable in having the inflorescence shaped as a long, oblong cone. It is 13 by 8 cm in size.[7] The flower heads are cup-shaped, and the flowers within them contain nectar.[9] The inflorescence is subtended (i.e. surrounded or covered) by 'involucral bracts'.[7] These outer bracts range in colour from carmine to pink to creamy-green or whitish, this colour contrasts with the characteristic hairy black fringe on the margins of the apex of the bract.[5][7][9] The inner bracts are shaped oblong to spatulate, and are typically curved inwards at the tips. These tips are rounded and also covered in a black, sometimes white, beard of fuzzy hairs.[7]

 

The fruit is a nut, its surface densely covered in hairs.[7] These small nuts are packed together within the dried inflorescence, which remains on the plant after senescence. When eventually released, the seeds are dispersed by means of the wind.[6]

 

Similar species

It is similar to Protea laurifolia, whose flower heads also possess a hairy black fringe on their bracts, a species found further to the west. P. laurifolia can be distinguished by means of its leaves having a very short petiole, these leaves have a heavy horny margin and are usually more bluish or silvery-coloured than those of P. neriifolia.[7]

 

Distribution

Protea neriifolia occurs in both the Western and the Eastern Cape provinces of South Africa.[4] It occurs in the southern coastal mountain ranges of South Africa, between Cape Town and Port Elizabeth.[citation needed] It grows in the mountain ranges of Hottentots Holland, Langeberg, Groot Winterhoek, Elandsberg, Rooiberg, Kammanassie, Potberg,[6] Riviersonderend,[5][6] Kogelberg and Jonkershoek, as well as at Garcia's Pass[5] and near the towns of Tulbagh and Ceres.[6]
