The species is a
deciduous geophytic,
perennial herb, which resprouts annually from a hemispherical, cream-coloured
corm. The oval, dull light green leaves are 3.5 cm long by 1.7 cm wide, on a 4 cm long
stalk. The flower is enclosed in a green, brown and maroon
spathe 5 cm long, appearing in December. It was named after Australian botanist
L.A.S. Johnson after his 70th birthday. ==Distribution and habitat==
