Caladenia amoena  |  

The Charming Spider-orchid grows to 5-10 cm tall and has yellowish-green flowers, with red stripes. This species occurs to the north east of Melbourne in the Greensborough-Plenty-Hurstbridge area and is known from only two small populations. Typically found in grassy dry forest, the Charming Spider orchid has a summer dormancy period, commencing as the soils dry out in late spring and shooting in response to soaking rains in late autumn. Given its proximity to urban areas, trampling and recreational activities pose a threat to this species.
