Thelymitra antennifera
''Thelymitra antennifera'', commonly called the Rabbit-eared Sun Orchid, Lemon–scented Sun orchid or Vanilla orchid is a species of orchid which is native to Western Australia, South Australia and Victoria and northern parts of Tasmania.
==Description==
''T. antennifera'' is a tuberous, perennial herb, 10–25 cm tall with yellow flowers from July to October. Its leaf is circular in cross–section, 5 to 12 cm long and 2 to 3 mm wide. The inflorescence consists of one to four yellow flowers on a wiry, zig-zagged often pinkish stem. Each flower is 20 to 40 mm across with a lemon or vanilla scent. The sepals and petals are 12 to 20 mm long and 4 to 6 mm wide, the sepals having a broad, reddish–brown band on their outer surface. The column is 5 to 6 mm long and 2 to 3 mm wide with dark brown arms that are ear-like and held high above the column.〔(【引用サイトリンク】url=https://www.naturalvaluesatlas.tas.gov.au/downloadattachment?id=14590 )〕 As with others in the genus, it reproduces by seeds but is unusual in that it is one of the few that develops tubers on the end of stolon–like roots, allowing it to form new colonies.〔(【引用サイトリンク】url=http://keys.trin.org.au/key-server/data/08090a09-0d0e-410b-860c-020705070e0e/media/Html/genera/Thelymitra.htm )〕 The flowers are insect pollinated and open readily, even on cool days and are long–lasting.
