Allocasuarina mackliniana is a species of flowering plant in the family Casuarinaceae and is endemic to southern continental Australia. It is a dioecious, rarely a monoecious shrub that has more or less erect branchlets up to Шаблон:Cvt long, the leaves reduced to scales in whorls of seven to ten, the fruiting cones Шаблон:Cvt long containing winged seeds (samaras) Шаблон:Cvt long.
Description
Allocasuarina mackliniana is a dioecious, or rarely a monoecious shrub that typically grows to a height of Шаблон:Cvt and has smooth bark. Its branchlets are more or less erect, up to Шаблон:Cvt long, the leaves reduced to spreading or curved, scale-like teeth Шаблон:Cvt long, arranged in whorls of seven to ten around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are Шаблон:Cvt long, Шаблон:Cvt wide. Male flowers are arranged in thick, dense spikes Шаблон:Cvt long, the anthers Шаблон:Cvt long. Female cones are cylindrical and sessile or on a peduncle up to Шаблон:Cvt long. Mature cones are cylindrical, mostly Шаблон:Cvt long and Шаблон:Cvt in diameter, the samaras dark reddish-brown to black, and Шаблон:Cvt long.[1][2]
Taxonomy
Allocasuarina mackliniana was first formally described in 1989 by Lawrie Johnson in the Flora of Australia from specimens collected near Lucindale in 1986.[3][4] The specific epithet, (mackliniana) honours "Miss Ellen D. Macklin, of Adelaide".[4]
In the same edition of Flora of Australia, Johnson described three subspecies of A. mackliniana, and the names are accepted by the Australian Plant Census:
- Allocasuarina mackliniana subsp. hirtilinea L.A.S.Johnson[5] has articles Шаблон:Cvt long, eight or nine teeth, the "ribs" along the articles slightly rounded and the furrows between the ribs softly hairy.[6][7]
- Allocasuarina mackliniana L.A.S.Johnson subsp. mackliniana[8] has articles Шаблон:Cvt long, seven to ten teeth, the "ribs" rounded, the furrows with minute, soft hairs. It is similar to A. paradoxa.[9][10]
- Allocasuarina mackliniana subsp. xerophila L.A.S.Johnson[11] is intermediate between the other two subspecies, and has articles Шаблон:Cvt long, seven or eight teeth, the "ribs" nearly flat to slightly rounded and the furrows between the ribs softly hairy when young.[12][13]
Distribution and habitat
This sheoak is found from the southern Mount Lofty Ranges in South Australia to western Victoria. Subspecies hirtlinea grows in woodland and is restricted to the western parts of the Grampians National Park.[6][7] Subspecies mackliniana grows in heath from the southern Mount Lofty Ranges to Portland in Victoria[9][10] and subsp. xerophila grows in heath from near Pinnaroo and Keith in South Australia to the Wyperfield and Little Desert National Parks in Victoria.[12][13]
