''Astroloba congesta'' is a small succulent plant of the Astroloba genus, indigenous to the Eastern Cape, South Africa.〔U. Eggli: ''Illustrated Handbook of Succulent Plants: Monocotyledons''. Springer Science & Business Media, 2001. p.187.〕 It is often considered merely to be the eastern form of ''Astroloba foliolosa''.〔Pandora Roberts Reinecke: ''Genus Astroloba Uitewaal (Liliaceae)''. UCT Department of Biological Sciences. 1965.〕 ==Description== ''Astroloba congesta'' is a compact ''Astroloba'' species, with circa 7cm wide stems that are densely covered in sharply-pointed leaves, which sometimes grow in tiers, or in a rough spiral. The leaves are a glossy dark green in colour, concave on their upper faces, smooth, sharp with slight keels, and point upwards and outwards. Like its closest relatives - ''Astroloba foliolosa'' and ''robusta'', it produces cream-white flowers in the rainy season (September-January in habitat), tinged with green, on unusually short pedicels. However the inflorescence of ''congesta'' is often branched. It is easily confused with its close relative to the west, ''Astroloba foliolosa'', and the two species form a transition, with intermediates throughout the gradation. The two forms are similar looking and ''Astroloba congesta'' was even formally classed as a subspecies of its more widespread relative. It can be distinguished from ''Astroloba foliolosa'' by its darker green colour, and by its larger, less compact, more spreading leaves. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Astroloba congesta」の詳細全文を読む スポンサード リンク
