Description

''Eucalyptus brevistylis'' is a tree that typically grows to a height of and forms a lignotuber. It has fissured, greyish to reddish brown, fibrous to stringy bark that tends to be papery on the outside. The leaves on young plants and on coppice regrowth are egg-shaped to heart-shaped, long, wide, mid-green on the upper surface, paler below, and always have a petiole.

Distribution and habitat

Rate's tingle grows in wet forests near Walpole. It was previously confused with two other "tingle" species, the red tingle, '' E. jacksonii'' and the yellow tingle '' E. guilfoylei''. The name "tingle" or "tingle tingle" is thought to be of
