|Notes:||Spread by: probably by birds and water. Invades: rainforest, creeks, swamps, floodplains and roadsides; may be a problem in sugar cane. Notes: introduced as a garden ornamental. More common in the Whitsundays but also recorded in the Pioneer valley. Balloon vine (C. grandiflorum), a Class 3 declared plant in Queensland, is a very similar species but is far more hairy and leaves, flowers, fruit and seeds are all larger. This species was recorded from Conway in the early 1990’s but there have been no sightings recorded since.|
