The flora of the Daintree contains an almost complete record of the evolution of plant life on Earth, including extremely ancient flowering plant families found nowhere else. We are passionate about the conservation of the plants found in the Daintree Lowland Rainforest. We hope you'll enjoy learning about these plants as much as we have and will want to see the Daintree Lowland Rainforest protected forever.
The Daintree Lowland Rainforest is one of the oldest rainforests on Earth having survived undisturbed for over 120 million years. It holds exceptionally high biodiversity and conservation value and is the largest continuous area of tropical rainforest remaining in Australia.
Rainforests once covered much of eastern Australia, however, as conditions became drier the rainforest contracted and today the Daintree provides a refuge for many unique species. The Bennett’s Tree-kangaroo, Musky Rat-kangaroo, and the Southern Cassowary can be found here, as well a number of endemic plant species that have retained the same primitive characteristics of their ancestors. The flora of the Daintree contains an almost complete record of the evolution of plant life on Earth, including extremely ancient flowering plant families found nowhere else.
Before each purchase of a property in the Daintree Lowland Rainforest, we conduct a vegetation survey to confirm the conservation values. As we document the occurrence of interesting, endemic and threatened species we will share them on this page.
Green Dinosaur (Idiospermum australiense)
This species represents one of the earliest known lineages of flowering plants, dating back 120 million years. They are found in very few locations in north-eastern Queensland (e.g. the Daintree National Park and nearby freehold properties) and only in the very wet parts of the rainforest. The Idiospermum has provided justification for the description of the Daintree as the oldest continuously existing rainforest in the world. They have been called the Green Dinosaur and the Daintree - the place where flowers began. They are found in the fossil record going back 120 million years and are of great significance to science and our understanding of the evolution of flowering plants. Read more information here.
Cooper Creek Satinash (Syzygium glenum)
Only 17 individual plants of the Cooper Creek Satinash (Syzygium glenum) have ever been found. This large rainforest tree is restricted in its distribution to a small area of the Cooper Creek catchment in the Daintree Lowland Rainforest which is a hotspot for endemic flora. The trees only produce fruits every 7 to 11 years. Cassowaries don’t eat the fruit as it’s rather hard and dry.
Cooper Creek Satinash (Syzygium glenum)
The Endangered Cooper Creek Walnut (Endiandra cooperana). It is known from only a few hundred plants. Nearly all the records of this tree are from the surroundings of Cooper Creek in the lowlands of the Daintree Rainforest in Queensland, Australia. Its large yellow fruits are food for the equally Endangered Southern Cassowary.

Russell River Lime (Citrus inodora)
This is a native Citrus that grows as a shrub to 3m and is restricted to dense tropical lowland rainforests in two very small areas of the Wet Tropics of Queensland. One region is south of Cairns at the eastern foothills of the Bellenden-Ker range and the other in the Cow Bay Daintree lowlands. It is a relative of the better known Finger Lime of southern border districts. An interesting fact about the Russell River Lime is that “ínodora” refers to “no-smell” something that is usually highly characteristic of all Citrus species. It bears small spines along the stem and fruit reminiscent of small pale lemons.
Citrus inodora is listed as being Vulnerable to extinction Queensland Nature Conservation Act 1992.

Blush Walnut (Beilschmiedia obtusifolia). This type of native Laurel grows to 30m tall in rainforest and adjacent wet sclerophyll forest north from Port Macquarie in NSW to Papua New Guinea. Its fruits are dispersed by pigeons which could help explain its broad distribution. Another name in the sawmill industry was Ivory Walnut, presumably because it was scarce to source quality timber of this species.
Blush Walnut (Beilschmiedia obtusifolia)
Cairns Pencil Cedar (Palaquium galactoxylon). A seedling found during a survey of a freehold property in Cow Bay threatened by development. There are only species in this genus (Palaquium) found in Australia. It occurs in lowland tropical rainforests north of about Tully with one record from Palm Island near Townsville. The species grows a tall straight trunk thus reflects the “Pencil Cedar” name. The species epithet galacto-xylon refers to the freshly cut timber that releases copious amounts of milky sap. In the forests, these trees are quite distinctive but the seedlings are even more unique in having this colouration unlike any other in the forest. On closer examination, the cut parts exude white latex, a common trait in Sapotaceae (remember “Sap”-otaceae). The old leaves turn an attractive orange colour being unusually deciduous.
Cairns Pencil Cedar (Palaquium galactoxylon)
Noah's Walnut (Endiandra microneura). It produces large yellow oblong-shaped fruits that are dispersed by the Southern Cassowary. This species is only found naturally within the Daintree rainforests predominately north of the Daintree River and south of Cape Tribulation. This tree is noticeable in the forest as it produces a vibrant display of limp red new leaves. It is listed as Near Threatened under the Environment Protection and Biodiversity Conservation Act 1999.

Brown Pine (Podocarpus grayae) in the Daintree Lowland Rainforest. These trees can grow up to 30 metres tall and are found in well-developed rainforests from sea level to around 1,000 metres. Podocarpaceae is an ancient family of conifers that have their origins in the supercontinent of Gondwana.
Brown Pine (Podocarpus grayae)
Yarrabah Satinash (Syzygium angophoroides) grows in super saturated soils along with Red Beech, Paperbarks, Native Gardenia, Swamp Macaranga, Freshwater Mangrove and other trees which tolerate seasonal ponding. This young plant has stilt roots to help support it in the unstable mud and additionally the roots would allow for gaseous exchange, as roots within the soil would often be seasonally starved of air. Eventually this species can grow into gigantic dimensions. Another name used for this tree is “Swamp Satinash”.
Yarrabah Satinash (Syzygium angophoroides)
Thornton Aspen (Acronychia acuminata). This species is only found in rainforests surrounding Thornton Peak, the highest mountain in the Daintree. The fruits are attractive to birds including the Southern Cassowary and rainforest pigeons. The Thornton Aspen, a rare plant previously found at only six locations between the Daintree River and Bloomfield to the north. Listed as a Near Threatened species under the Queensland Environment Protection and Biodiversity Conservation Act 1999.
Thornton Aspen (Acronychia acuminata)
Isachne sharpii. The highly localised and Endangered grass was identified from open woodland paperbark habitat on Lot 110. This small grass grows to 15cm tall and was found growing in water in a ponded situation. This grass was first identified in 2001 from specimens found less than 1km from Lot 110. Originally named Isachne sp. Cape Tribulation (R.L.Jago 4560) and placed as a new species in 2010. Listed as an Endangered species under the Queensland Environment Protection and Biodiversity Conservation Act 1999.
Pothos brassii. This vine is endemic to the area between Cape Tribulation in the north and Bellenden Ker to the south. Altitudinal range from near sea level to 750 m. This slender vine has a stem not exceeding 2 cm in diameter and usually grows in well-developed lowland and upland rainforest.
Daintree Gardenia (Randia audasii). We found this Threatened species yesterday while surveying another property in Cow Bay for purchase and protection. This small tree is endemic to Far North Queensland and is restricted to the area between Cooktown, Cairns, and Atherton. The tree produces white perfumed flowers and fruit that are orange when ripe. It is listed as Near Threatened on the Queensland Nature Conservation Act 1992 (NCA).
Daintree Gardenia (Randia audasii)
In Australia, the vine, Hugonia jenkinsii has a distribution restricted to Cape York Peninsula and North East Queensland.
Sarcopteryx reticulata (Sapindaceae). This plant is rather obscure in the forest however the botanical language describing the plant is very precise. The genus refers to a fleshy winged fruit (sarco-pteryx) and the species epithet refers to the leaf venation being reticulated, referring to a network of veins.
Sarcopteryx reticulata (Sapindaceae)
Ant Plant (Myrmecodia beccarii). The Ant Plant epiphytic plant, it grows on another plant but is not parasitic. It lives harmlessly on Melaleuca trees and others with spongy bark in the wetlands and mangroves of tropical north Queensland. The Ant Plant has a special association with the Golden Ant (Iridomyrmex cordatus) which lives in the chambers of its tuber. What’s more, the Apollo Butterfly lays its eggs on this plant. The Golden Ants carry the butterfly eggs into the tuber chambers where they develop as butterflies.
The Ant Plant’s flowers are white and tubular, to 10mm, and the fruit is white/translucent containing a single seed. These single seeds are transported to other trees by the Mistletoe bird (dicaeum hirundinaceum).
It is listed as Vulnerable under the Queensland Environment Protection and Biodiversity Conservation Act 1999. It is threatened by habitat loss, invasion of weeds, and the illicit removal of the plants by plant and butterfly collectors.
Ant Plant (Myrmecodia beccarii)
Daintree Satinash (Syzygium monospermum). This species is only found in lowland rainforests between Cape Tribulation and Julatten. The tree provides food for the Endangered Southern Cassowary and owing to the size of its large white fruit that it produces straight from the trunk (an adaptation called cauliflory), few other animals other than possibly Fruit bats would disperse it. This tree was only botanically named in 2003. This unique tree species has a symbiotic relationship with Ants that inhabit the trunk of the tree. Little is known of the reason why Ants colonise the trunk of this tree however it is known that the internal structure of the tree is a purpose-built network of tunnels that allow Ants to undertake their entire life cycle, what the tree benefits from this is little known and currently remains unstudied.
