Clusia rosea, theautograph tree,copey,cupey,[4]balsam apple,pitch-apple, andScotch attorney,[5] is an evergreen, tropical and sub-tropicalflowering plant species in the familyClusiaceae. The nameClusia major is sometimes misapplied to this species.[6]
Clusia rosea is a tree native to the Caribbean, including the Bahamas,Hispaniola (such as inLos Haitises National Park), Cuba, Puerto Rico, and Florida.[7][8]
It is ahemiepiphyte; that is, it grows as anepiphyte on rocks or other trees at the start of its life and behaving like astrangler fig as it gets larger. Like a strangler fig, it successfully competes for light by outgrowing, overtopping and "strangling" its host tree with its many aerial roots.[9][7][8][10] These roots are among the fastest growing known; up to 12 inches (30 cm) in 24 hours.[11]
The petals are pink to white. The thin upper leaf tissue registers 'writing' giving it the common name "autograph tree". The tree produces a fleshy, light green toxic fruit; once the fruit splits, the seeds are consumed by birds and other wildlife.Clusia species are normallydioecious, but inC. rosea, there arepistillate (female) individuals only, and seeds are formed throughagamospermy.
This plant is cultivated as anornamental plant, for its flowers, foliage, and fruit. It is planted ingardens as a fruiting andornamental tree in sub-tropical climates, and used as ahouseplant in many climates.[12]

Clusia rosea has become a great threat to Sri Lanka, Hawaii, and many other tropical countries as an invasive plant.
In Sri Lanka it is spreading rapidly on the mountains of the central hill country. It especially grows on rocks and rock outcrops where it forms dense thickets. Being a hemiepiphyte that resembles astrangling fig, it also sprouts on branches and trunks of native trees and rapidly overgrows and strangles them. It therefore poses a great threat to what little remains of the native submontane forests, and the unique native vegetation around rock outcrops, such as on the Hantana mountain range near Kandy. It is known as Gal Goraka (ගල් ගොරක) or Gal Idda (ගල් ඉද්ද) inSinhalese.[13][14][15]
It is one of Hawaii's most invasive plants and grows in forests and open, disturbed areas in low elevations. It is spread by birds which eat its fruits.[7][8][16]
Clusia rosea is highly tolerant to extreme environments such as excessive salty winds and sprays and drought.[17]
The leaves were used to makeplaying cards in the West Indies. Some sign their autographs on the leaves and watch them grow.[18]
In Puerto Rico, in the past, parts of the plant were used to make game balls, to make tar and for firewood.[4]
