Diploglottis australis, known as the native tamarind, is a well known rainforest tree of eastern Australia. It is easily identified by the large sausage shaped leaflets.
The native tamarind grows in a variety of different rainforests, on basaltic and rich alluvial soils. The southernmost limit of natural distribution is Brogo near Bega (36° S) in New South Wales. They grow naturally along the east coast, northwards to near Proserpine (20° S) in tropical Queensland.[3]

The tree is medium to large, with long and broad leaves. It can achieve a height of over 35 metres tall and a trunk diameter of 75 cm. The trunk is cylindrical and flanged at the base, somewhat resembling the trunk of the Coachwood.
The branches bear alternate leaves, which are large and pinnate with conspicuously large leaflets. The leaf is generally 40–120 cm long and leaves on mature branches bear about 6–12 leaflets each, but on seedlings or coppice shoots the leaves may be simple or bear only 3–5 leaflets. The leaflets commonly are 10–30 cm long and 4–8 cm wide, broadly oblong to elliptic, bluntly pointed at the tip, not equal at the base, often covered with velvety golden brown hairs. The leaf veins are easy to see on both sides, more so on the underside. The midrib is slightly raised on the top surface.[4]
Flowers form in spring, being creamy brown in large and hairy panicles. The brown and hairy capsule matures from October to January. It contains a yellow/orange aril, which is pleasant to the taste. Within the aril is a triangular, pale brown seed.
Seed germination is reliable and fast, although seed collected from damp ground where it falls in large quantity, generally is heavily infested with insect grubs. Many species of rainforest birds eat the fruit, particularly the aril, and disseminate the seed. Prominent examples of such birds include the brown cuckoo dove, crimson rosella, Australasian figbird, green catbird, regent bowerbird, Australian brush-turkey, rose-crowned fruit-dove, topknot pigeon and wompoo fruit-dove.
An involved naming history exists for this species.[1][2] At all events, Diploglottis australis (G.Don) Radlk. has received support and clarification as the currently accepted name,[1][2] rather than the synonym of D. cunninghamii.[5]
The native tamarind is grown as a decorative tree in various parts of urban Australia, including behind the Mitchell Library in the city of Sydney. However, the tree is ill-suited to situations where strong winds damage its large leaflets.
The native tamarind is valued as an indigenous fruit tree because the aril may be eaten raw or added to jams and chutneys. It also is used as the basis for a tangy cool drink.

Diploglottis cunninghamii, conocido como Tamarindo Australiano (Native Tamarind en inglés) es un árbol común en la selva tropical del este de Australia. Se identifica fácilmente por sus grandes hojas en forma de salchicha.
El tamarindo australiano crece en diversos tipos de selva tropical, tanto en suelos basálticos como en ricos suelos aluviales. El límite meridional de su distribución es Durras Mountain cerca de Batemans Bay (35° S) en Nueva Gales del Sur. Aparece en la costa este hasta Proserpine (20° S) en la Queensland tropical.
Es un árbol de talla mediana a grande con hojas grandes y largas. Llega a tener una altura de más de 35 metros y un diámetro de 75 cm. Su tronco es cilíndrico y rebordeado en la base, algo parecido al tronco del palo satinado.
Las hojas son pinnadas y alternadas, algunas de más de 30 cm de largo. Son Anchas, elípticas, con una punta roma en el extremo, desiguales en la base, frecuentemente cubiertas de vello aterciopelado de color café o dorado. Los nervios de las hojas son fáciles de ver por ambos lados. El nervio central está ligeramente elevado en el envés.
La floración tiene lugar en primavera, con flores grandes, de color café en panículas grandes y vellosas. La cápsula, vellosa y de color café madura desde octubre hasta enero. Contiene un arilo amarillo anaranjado, agradable al gusto. Dentro del arilo se halla una única semilla triangular de color café pálido.
La germinación de la semilla es fiable y rápida. Es apreciada por una gran variedad de aves de la selva tropical, incluyendo la tórtola cuco parda, la rosela carmesí, el papahigos, el maullador verde, el ave de emparrado regente, el tilopo real, la paloma de rodete y el tilopo magnífico.
Como árbol ornamental y decorativo, se ve en varias partes de la Australia urbana, incluida la ciudad de Sídney. El tamarindo australiano debe resguardarse del viento debido a sus grandes hojas. Con el arilo se hace una bebida picante refrescante.
