Trichodesma zeylanicum

provided by wikipedia EN

Trichodesma zeylanicum, commonly known as Northern bluebell, camel bush or cattle bush, is a herb or shrub native to Australia.

Description

It grows as an erect herb or shrub up to two metres high, with a well-developed taproot. Flowers are blue, or rarely white.^[1]^[2]

Taxonomy

This species was first published as Borago zeylanica by Nicolaas Laurens Burman in 1768. In 1810, Robert Brown transferred it into Trichodesma, but this was retained only until 1882, when Ferdinand von Mueller transferred it into Pollichia. In 1891, Otto Kuntze transferred it into Boraginella, and in 1898 William Philip Hiern transferred it into Borraginoides. Despite these many later transfers, it is Brown's placement that is currently accepted.^[3]^[4]
