BIOLOGY The difference between these two systems is that nursery stock plants in the mini-cuttings system are raised from small and often serially-propagated rooted cuttings, whereas nursery stock plants in the micro-cuttings system are raised initially in tissue culture [16–26].

Eucalypteae) as Eucalyptus and are indeed very similar, but they have a few distinct spotting characters that can help you to tell them apart. The most important commercial use of eucalypts is in forestry and this is an area where there has been considerable conflict between conservation and timber interests in the last 20 years or so, particularly as resistance to woodchipping and the move to preserve old growth forests have gained momentum. They are rich in volatile oils, making them vulnerable to bushfi res. Jarrah is also known a Eucalyptus Marginata and Marri is known as Corymbia Calophylla. Eucalypts or gum trees are drawn from three genera – Angophora, Corymbia and Eucalyptus (the largest of the three genera). It is, in fact, the operculum which gives Eucalyptus its name (eu, well and calyptos covered). Note the absence of an operculum, the ribs along the capsule, and the pale petals.

Stringybarks: Outer bark thick, brownish, fibrous and stringy, persistent on trunk and larger branches. Phylogeny, major clades and infrageneric classification of Corymbia (Myrtaceae), based on nuclear ribosomal DNA and morphology. The flowers of all eucalypts contain nectar and many species are important in the beekeeping industry. Most Australians may not be able to identify a particular species (there are hundreds of them, after all!) at intervals that do not allow sufficient time for seedlings to grow to maturity, flower and set seed. Boxes: Rough bark, sub-fibrous and interlace… Very long glossy green leaves . Portugal and Spain together produce more than 50% of the world's supply with Australian production being around 5%. These genera are both in the same family (i.e. Although often thought of as applying to the genus Eucalyptus, the term "eucalypt" is now broadly used to include the closely related genera Angophora and Corymbia. They occur in almost all vegetation types across the continent in coastal, arid, tropical and alpine environments.
