''Caladenia dilatata'', green comb spider orchid, is a deciduous terrestrial orchid species found throughout southern Australia. == Morphology == ''Caladenia dilatata'' is a terrestrial orchid that consists of a single large, flower. The plant itself grows 15 - 35 tall, from two round tubers that are protected in a fibrous tunic.〔 It has one green basal leaf that is long and hairy.〔 Similar to other spider orchids, the flower consists of four long, lanceolate and curved filamentous modified sepals.〔 The sepals are green-yellow, with a maroon color on the dorsal side, measuring up to 5 – 5.5 cm long.〔 They droop downwards and taper into fine, yellow-brown clubbed tips that are covered with dark-colored hairs.〔 The pair of basal sepals spread away from each other, but may also curve and cross.〔 The flower also consists of an egg-shaped green labellum that is a dark maroon on the lateral side〔 with four rows of calli towards the center.〔 The lateral margins of the labellum are green and lobed, with the lobes erect.〔 The front margins are fringed and the mid-lobe is curved downwards. It grows in response to soaking rains, producing only a leaf that will remain dormant during the winter season.〔 However, the flower may be aborted in severely dry weather.〔 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「Caladenia dilatata」の詳細全文を読む スポンサード リンク
