Pseudoweinmannia lachnocarpa

Pseudoweinmannia lachnocarpa is a rainforest tree of eastern Australia. Common names include rose marara, mararie, scrub rosewood and red carabeen. The species name lachnocarpa is from the Greek, referring to the "woolly fruit". The genus name refers to the similarity of another genus, Weinmannia, after the German eighteenth century pharmacist J.W. Weinmann.

Taxonomy

Originally described by Ferdinand von Mueller as Weinmannia lachnocarpa in 1874,[1] it was given its current name in 1930 by Adolf Engler.[2] It is a member of the family Cunoniaceae.

Habitat

This tree is found in prime rainforest situations, on the better alluvial and volcanic soils with high rainfall. In riverine, littoral, tropical and sub tropical rainforest from the Richmond River, New South Wales to Cooktown in tropical Queensland.[3]

Description

A small to large tree, up to 40 metres tall, and a very wide butt of 2.5 metres. The base of the tree is often significantly and widely buttressed. The thin bark is grey or fawn. Rough to touch with small pustules and scales. Small branches smooth, greyish white or brown. With green at the tips and white oval shaped lenticels.

Leaves are in threes, opposite on the stem. Leaflets 3 to 15 cm long, 1 to 5 cm wide.[4] Elliptic in shape, toothed, glossy green and almost without leaf stalks. Leaf veins raised and noticeable on both surfaces.

Flowers and fruit

White flowers form in August on racemes, about 5 cm long. As with the related Coachwood, the flowers have no petals. Fruit matures from February to April, being an ovate capsule, 6 to 9 mm in diameter, covered in golden hairs. Seeds are egg shaped, 1 mm in diameter. Germination from fresh seed is unreliable.

gollark: I mean, outside of toy models or whatever.
gollark: Maybe you could make a good scifi thing a hundred years in the future or something about faster computers/better optimization algorithms/distributed system designs/something making central planning more tractable. Although in the future supply chains will probably be even more complex. But right now, it is NOT practical.
gollark: In any case, if you have a planned system and some new need comes up... what do you do, spend weeks updating the models and rerunning them? That is not really quick enough.
gollark: If you want to factor in each individual location's needs in some giant model, you'll run into issues like:- people lying- it would be horrifically complex
gollark: Information flow: imagine some farmer, due to some detail of their climate/environment, needs extra wood or something. But the central planning models just say "each farmer needs 100 units of wood for farming 10 units of pig"; what are they meant to do?
