Pittosporum rubiginosum (Pittosporaceae)

Pittosporum rubiginosum

The Hairy Red Pittosporum is an endemic shrub that occurs in the dark shade of the rainforest understorey. I have hardly seen this species grow taller than 2-3m tall. The leaves are soft textured, hairy, largish (although very small ones occur), and look clustered new the twig tips. The leaf are distinctively obovate and the veins form very distinctive loops far inside the leaf margin. The leaf underside is also often purplish.
As the common name for this endemic shrub species suggests, the fruits of the species are hairy, and the fruits split widely open into two parts, exposing the seeds covered in bright red pulp.

Eriobotrya japonica (Rosaceae)

Eriobotrya japonica DSC_0636 (4)

The loquat (Eriobotrya japonica) is a tree from the Rose family, native to south-central China. It is a large evergreen shrub or small tree, grown in private gardens as an ornamental with sweet smelling flowers, and probably for its edible yellow fruit.

The loquat can grow to be a small tree with a rounded crown to 5–10 metres. (I have never seen one so big.). The leaves are alternate, simple, largish (around 10–25 centimetres long), dark green, tough and leathery in texture, with a toothed margin. The leaf undersides are densely velvety-hairy with thick yellow-brown pubescence; the young leaves are also densely hairy above, but these hairs soon rubs off.

The loquat has some medicinal uses in the Chinese pharmacopeia.

More on this when I get the chance to try out the sweet fruits.

Syzygium jambos (Myrtaceae)

The Rose Apple is planted quite frequently in urban areas, but comparatively few people know that it is delicious. It’s called the Rose Apple for a good reason – the flesh has a rosy flavour.

Mitrephora diversifolia (Annonaceae)

Mitrephora diversifolia DSC_0112

This native tree Mitrephora diversifolia is also known as the flying duck flower (No offence to whomever assigned that name but I can’t see any resemblance), and is one of the more glorious native members of the custard apple family here. The brilliant flowers can vary a bit in colour it seems and are quite large (I remember something ~5cm across). Like some species of the Custard Apple family, some of the floral parts of this species are fused at the tips to form somewhat of a basket. This feature is probably a nuptial chamber for beetles that pollinate the flower. The leaves are hairy, dark green above, and are ovate in shape. The twigs have numerous lighter coloured lenticels (pores).

Recent phytochemical research has shown that root extracts of the plant may have antimalarial activity (Mueller et al. 2009). The species is found in Cape York and also the Malesian region (which includes Southeast Asia) – I’d so love to see this in the wild.

Myrsine subsessilis (Primulaceae)

Myrsine subsessilis DSC_0574

One of the various native species of Myrsine, this endemic shrub is probably one of the more easy to recognize species as the veins are quite prominent on the leaf upperside, and the midrib is raised. Like most members of the genus, the distinctive translucent oil dots in the leaf will help to at least confirm that this shrub belongs to the Primula family. In this species, the oil dots are round and red. This feature is more obvious in dried specimens.

More on this sometime.

Phytolacca octandra (Phytolaccaceae)

Phytolacca octandra DSC_0565 (2)

Phytolacca octandra is a very descriptively named soft-stemmed shrub or herb by Linnaeas (Greek: “phyton” meaning plant; Neo-Latin: “lacca” meaning lacquer, alluding to the red dye of the berries). The common name Inkweed is also an allusion to the red inky juice in the ripe berries. The specific epithet “octandra” refers to the eight sections of the fruit.

This soft leaved weedy shrub is a native of tropical America but in Australia is found widely from the tropics to temperate regions. In tropical rainforest, it is found in road clearing or rainforest gaps.

The berries look enticing but are known to be poisonous.

Saurauia andreana (Actinidiaceae)

Saurauia andreana Ellinnja Falls DSC_0412 (5)

This hairy rainforest shrub is the only Australian representative of the Kiwi fruit family. Interestingly it was first named Dillenia andreana by Mueller, probably due to to the superficial similarly of the appearance of the flowers to Dillenia. But of course, Dillenia is from a totally different family altogether (See Dillenia alata).

Andre’s Saurauia is often found along water courses in lowland to upland rainforest. The leaves are alternate, wider nearer the apex (i.e. obovate-shaped), have toothed margins, and are hairy throughout. The flowers are borne in the leaf axils and often facing downwards. The petals are white or white with hints of pink.
