Eucalyptus alligatrix
Eucalyptus alligatrix, commonly known as the silver stringybark, is a tree endemic to southeastern Australia. It has rough, fibrous bark on the trunk and branches, lance-shaped adult leaves, flower buds usually arranged in groups of three, white flowers and cup-shaped, bell-shaped or cone-shaped fruit. Description. "Eucalyptus alligatrix" is a tree that sometimes grows to a height of . It has thick, fibrous, furrowed bark on the trunk and branches. The leaves on young plants and on coppice regrowth are arranged in opposite pairs, broadly egg-shaped to more or less round, long, wide and lack  a petiole. Juvenile leaves are also dull bluish green with a whitish bloom. Adult leaves are bluish green, lance-shaped, often curved, long and wide on a petiole long. The flowers buds are usually arranged in groups of three, sometimes seven, in leaf axils. The groups are on a peduncle long, individual buds on a pedicel up to long. The buds are diamond-shaped to spindle-shaped, long and wide. The operculum is cone-shaped and slightly shorter than the floral cup. The flowers are white and the fruit is a woody, cup-shaped, bell-shaped or cone-shaped capsule  long and wide. Taxonomy and naming. "Eucalyptus alligatrix" was first formally described in 1991 by Lawrie Johnson and Ken Hill from a specimen collected south-west of Jamieson. The description was published in the journal "Telopea". The specific epithet ("alligatrix") is the feminine form of the Latin word "alligator" meaning "one who binds", hence "she who binds together", referring to the characteristics of this species that are intermediate between those of "E. cinerea" and "E. cephalocarpa". In 1995, Ian Brooker and Andrew Slee described three subspecies and published the descriptions in "Australian Systematic Botany": Distribution and habitat. This eucalypt grows  in woodland, often regenerating in previously cleared paddocks. Conservation. Subspecies "limaensis" and "miscella" are both classified as "Vulnerable" under the Australian Government "Environment Protection and Biodiversity Conservation Act 1999". The main threats to Lima stringybark include ringbarking of trees by livestock, soil degradation, weed invasion and grazing. A recovery plan for the subspecies has been prepared. Subspecies "miscella" is only known from a single grazing property near Rylstone where regeneration is minimal. The main threats to this subspecies include grazing by livestock, habitat destruction and inappropriate fire regimes.
