Diploglottis harpullioides, commonly known as Babinda tamarind, is a rainforest tree in the lychee and maple family Sapindaceae which is found only in northeast Queensland, Australia.
Diploglottis harpullioides is a shrub or small tree growing up to 5 m (16 ft) tall. The compound leaves may reach 58 cm (23 in) in length (including the petiole), and have between 4 and 8 stiff, hairless leaflets arranged in opposite pairs. Each pair is larger than the previous pair closer to the junction with the branch. Leaflets are elliptic-oblong with accuminate tips and very oblique bases, and measure up to 32 cm (13 in) long by 11 cm (4.3 in) wide. They have between 9 and 14 lateral veins each side of the midrib which curve inside the leaf margin and connect to adjacent veins. [4] : 391 [5] [6] [7]
The inflorescences are very small compared to other members of Diploglottis, being just 2.5 cm (0.98 in) long. They are panicles growing from the leaf axils, carrying flowers about 5 mm (0.20 in) wide on pedicels up to 7 mm (0.28 in) long. The sepals are pale green, and the 5 white petals measure up to 5.5 mm (0.22 in) long. [4] : 392 [5] [6] [7]
The fruit is a large, green, hairless or sparsely hairy capsule measuring up to 4 cm (1.6 in) long by 6 cm (2.4 in) wide with walls about 4 mm (0.16 in) thick. They have 1–4 valves which split open to release the seeds. The valves are silky hairy on the inside and have 1 brown seed which is completely enclosed in a red aril. Usually 2 valves are aborted and don't mature, appearing as small lumps on the base of the fruit. [4] : 392 [5] [6] [7]
The Babinda tamarind was first described by the Australian botanist Sally T. Reynolds in the first of a series of papers on the Sapindaceae species in Australia. This paper, titled "Notes on Sapindaceae in Australia, I" was published in 1981 in Austrobaileya, the official journal of the Queensland Herbarium. [4]
The genus name Diploglottis comes from the Neo-Latin words diplo- meaning double, and glottis meaning tongue, which is a reference to the two tongue-like scales on the petals. [7] The species epithet harpullioides is a reference to this plant's similarity to the genus Harpullia. [7]
This species is endemic to northeastern Queensland, and occurs in coastal flats and adjacent ranges from near Rossville and Cedar Bay in the Ngalba Bulal National Park, south to about Innisfail, and from sea level to about 400 m (1,300 ft). It is an understorey tree in well developed rainforest. [4] : 392 [5] [6] [7]
The Babinda tamarind is listed by the Queensland Government's Department of Environment, Science and Innovation as least concern. [1] As of 4 February 2024 [update] , it has not been assessed by the International Union for Conservation of Nature (IUCN).
Diploglottis is a genus of 11 species of trees known to science, constituting part of the plant family Sapindaceae. They grow naturally in rainforests and margins of adjoining humid forests in eastern Australia and New Guinea. Some species are known as native tamarind or small-leaved tamarind; they have no direct relationship with the true tamarind.
Diploglottis campbellii is a rainforest tree northern New South Wales and southeastern Queensland. Growing to 30 metres tall, it is commonly known as the small-leaved tamarind. It is rare and threatened and is restricted to a small number of sites, each with a maximum of 3 trees per site. However, it is readily available from nurseries in the Northern Rivers area of New South Wales, and in south-eastern Queensland.
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.
Jagera pseudorhus, commonly named foambark, is a species of rainforest trees, in the northern half of eastern Australia and in New Guinea, constituting part of the flowering plant family Sapindaceae. Named for the saponin foam that forms on the bark after heavy rain.
Elattostachys nervosa, known as the green tamarind or beetroot tree is a common rainforest tree of eastern Australia. Found in all types of rainforest, growing from Paterson, New South Wales in the south to Gympie in south east Queensland. The name Elattostachys refers to "little spikes", a flower feature of other plants in this genus. Nervosa refers to the prominent leaf venation. Beetroot Tree refers to the beetroot red leaves of the new growth.
Arytera distylis, known as the two-leaved coogera or twin-leaved coogera is a rainforest tree of eastern Australia. It grows by streams or in sea side rainforests. It occurs from the Orara River in the Mid North Coast region of New South Wales, extending up to Maryborough in south east Queensland.
Acronychia pubescens, commonly known as hairy acronychia or hairy aspen, is a species of tall shrub or small tree that is endemic to eastern Australia. It usually has trifoliate leaves, rarely simple leaves, groups of whitish flowers in leaf axils and creamy to yellowish, elliptical to spherical fruit.
Elattostachys xylocarpa, known as the white tamarind or short-leaf beetroot is a common rainforest tree of eastern Australia. Found in the drier rainforests, which are based on volcanic soils. From as far south as the Orara River in northern New South Wales to Bowen in tropical Queensland. The name Elattostachys refers to "little spikes", a flower feature of other plants in this genus. xylocarpa refers to the hard woody fruit.
Lepidopetalum is a genus of six species of trees known to science, constituting part of the plant family Sapindaceae.
Boronia excelsa is a plant in the citrus family Rutaceae and is endemic to a small area in Far North Queensland. It is an erect shrub with woolly-hairy branches, simple, stalkless, more or less hairless leaves, and pink to white, four-petalled flowers.
Gardenia actinocarpa is a rare and endangered plant in the madder family Rubiaceae that grows in a very restricted area within the Wet Tropics rainforest of north-east Queensland.
Pseuduvaria froggattii is a rare species of tree which is restricted to a very small part of northeastern Queensland, Australia. It is a member of the custard apple and soursop family Annonaceae, and was first described in 1887. Despite the small range its status considered to be least concern.
Harpullia ramiflora, commonly known as the Claudie tulipwood or Cape York tulipwood, is a tree in the Sapindaceae family native to north east Queensland, New Guinea and parts of Malesia.
Pittosporum rubiginosum, commonly known as hairy red pittosporum, is an evergreen shrub in the family Pittosporaceae which is endemic to northeastern Queensland, Australia. It was first described in 1840.
Harpullia rhyticarpa, commonly known as slender harpullia, is a plant in the family Sapindaceae which is endemic to the rainforests northeastern Queensland, Australia.
Diploglottis diphyllostegia, commonly known as the northern tamarind, native tamarind or wild tamarind, is a tree in the lychee family Sapindaceae which is endemic to Queensland, Australia. It is an attractive tree with potential in cultivation, with a dense crown of dark green leaves and masses of fruit in spring and summer.
Diploglottis obovata, commonly known as blunt-leaved tamarind, is a plant in the family Sapindaceae endemic to central eastern Queensland, Australia. Until 1987 it was considered to be a form of the very closely related Diploglottis diphyllostegia.
Cupaniopsis flagelliformis, commonly known as brown tuckeroo or weeping flower tamarind, is a tree in the lychee, guaraná and maple family Sapindaceae which is endemic to eastern Australia. It is a small tree that inhabits drier or seasonal rainforests.
Diploglottis bernieana, commonly known as Bernie's tamarind or large leaf tamarind, is a plant in the maple and lychee family Sapindaceae. It was first described in 1987 by the Australian botanist Sally T. Reynolds and is found only the Wet Tropics region of northeastern Queensland, Australia.
Diploglottis alaticarpa is a plant in the maple and lychee family Sapindaceae which is endemic to northeast Queensland, Australia. It was first recognised as a distinct species in 1994 and was formally described in 2014.
