Eucalypt description
1.0, Eucalypt fruit, (Greek eu 'good' and kalyptus 'cover', cap-like operculum covers the flower buds.
Eucalypt fruit is a seed-bearing capsule in a woody expanded receptacle, opening at the top when seed shed after dehiscence.
Operculum is the cap of a flower bud, formed by fusion of sepals and petals and which dehisces at maturity, exposing reproductive organs.
2.0, Eucalypt mallee is a woody plant, multistemmed from ground level, with a woody lignotuber at the base, which has dormant buds for recovery after fire regeneration following crown destruction, and a shrub, is a mature plant, up to 1m, irregularly branched, and without a principal erect stem.
3.0, Eucalypt bark is tissues outermost to the cambium in a woody plant, mooth barks lose all their bark each year, but roughbarks do not shed their bark each year.
Stringybark is persistant dead bark with long fibres, scribbles are causeed by burrowing insect laevae and rugose bark is wrinked bark.
4.0, Leaves Green-leaved ash are plants with juvenile leaves and coppice is young stems shooting from a stump or juvenile growth fron mature trunks.
Discolorous leaves have different colour upper and lower surfaces.
5.0, Eucalypt kino exudates from the bark of River Red Gum when injured, exudes an abundance of kino and it may be ‘tapped’.
Kino is produced by various trees including the many eucalypts called 'bloodwoods'.
Kino, once called ‘red gum’, oozes out of the bloodwoods with a very dark red colour and is compared with the resin flow from conifers.
The red-currant jelly-like kino from the tree, hardens to dark red angular fragments, which are brittle, easily powdered, and have no smell.
It has a very astringent taste, can precipitate proteins, and has chief constituent | Kinotannic acid, C18H18O8 |.
It was an Australian native folk medicine and a once popular treatment for diarrhoea, skin lesions, scabies, sore throats, and powders to arrest haemorrhage.
Also, some of the more than 30 eucalypt kinos were used by first settlers in Australia for ink and for staining leather black
Commercial timber is damaged by the ‘Gum veins’, when the kino ducts are form when the cambial layer of eucalypts is injured, by fire or insects.
The present East Indian kino, Malabar kino and Amboyna kino are the evaporated juice from Pterocarpus marsupium, Butea frondosa and Eucalyptus siderophloia and Eucalyptus camaldulensis.
