Species of tree

Psidium cattleyanum (World Plants : Psidium cattleianum), commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. The species is named in honour of English horticulturist William Cattley. Its genus name Psidium comes from the Latin psidion, or "armlet." The red fruited variety, P. cattleyanum var. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. it is considered the most invasive plant in Hawaii.

Psidium cattleyanum is a small, highly branched tree that reaches a maximum height of 13 meters, although most individuals are between 2 and 4 m. P. cattleyanum has smooth, grey to reddish brown bark, with oval to elliptical leaves that grow to 4.5 cm in length. It bears fruit when the plants are between 3 and 6 years old. This fruit has thin skin that ranges from yellow to a dark red or purple, is ovular in shape, and grows to around 4 cm in length. Its flowers grow either individually or in clusters of three, and each flower has five petals. Though native to Brazil, it is now distributed throughout many tropical regions. P. cattleyanum has modest economic impacts in Hawaii due to its edible fruits. However, products made from P. cattleyanum are not commercially available because of a lack of market and the heavy presence of fruit flies. This renders the fruits inedible soon after they are picked.

P. cattleyanum occurs primarily in mesic tropical rainforest environments Its native range is restricted to the Amazonian Basin in Brazil, but it has established in many other tropical areas of similar characteristics. P. cattleyanum is prevalent in both undisturbed Additionally, P. cattleyanum is both very shade tolerant It is also capable of withstanding heavy leaf litter and responding to bending or breaking of its branches by generating vigorous shoots.

Native to Brazil where it is known as araçá (ara SAH) and adjacent tropical South America, it is closely related to common guava (P. guajava), and like that species is a widespread, highly invasive species in tropical areas throughout the Indian and Pacific Oceans. such as in the Azores, though it is not as invasive there. It tends to form dense, monotypic stands which prevent regrowth of native species, and is very difficult to eradicate; it also provides refuge for fruit flies which cause extensive agricultural damage. It is able to propagate quickly due to the spread of its seed, which occurs as its seeds fall and as birds and feral pigs transport fruits,

P. cattleyanum grows effectively in undisturbed areas, Its ability to thrive in a variety of different habitats under many different ecological conditions and Hawaii. However, some insects cannot be used due to the potential for certain species to attack more than P. cattleyanum. The wood of the tree is hard, compact, durable, and resistant, and is used for lathe work, tool handles, charcoal, and firewood. The plant is indispensable for mixed planting in reforestation of reclaimed and protected areas in Brazil. Necklaces are reported to be handcrafted in Tanzania by tying together beads made of individual fruits.
