Helichrysum monogynum, also known as red tinderbox,[1] is a species of flowering plant within the family Asteraceae. The species is listed as endangered due to its restricted range within 8 km² of suitable habitat and the threat of habitat degradation due to urbanisation and recreational activities.[1]
Leaves
The leaves of Helichrysum monogynum vary from 13 - 31 mm in length and 2 - 4 mm in width.[2] Leaves can be lanceolate, oblanceolate, or narrowly spathulate, and they are more than five times longer than their width.[2] H. monogynum lacks leaf rosettes.[2]
Flowers
The capitulum is cylindrical or narrowly campanulate.[2] The length of the capitulum varies from 3.5 to 45 mm.[2] The capitula have a heterogamous sex ratio, meaning they contain both male and female flowers.[2] H. monogynum is a hermaphrodite species, which possesses a low rate of seed germination.[1] There are approximately 10 to 11 flowers per capitulum, with 1 to 2 being female and 7 to 10 being hermaphrodite.[2] The corolla of the flowers is yellow with reddish lobes.[2] The colour of the phyllaries (modified leaves surrounding the base of the flower) can be outer reddish or pinkish, while the inner ones are whiteish or all yellow.[2]
