Teucrium betchei is a perennial herb that typically grows to a height of and has rod-like stems that are square in cross-section. The leaves are arranged in opposite pairs, linear to very narrow lance-shaped, long, wide and more or less sessile. The flowers are mostly arranged in groups of three to five in upper leaf axils, each flower on a pedicel long. The five sepals are long, joined at the base for about half their length. The petals are white, the lower middle lobe long. Flowering mainly occurs in summer.[1] [2]
This germander was first formally described in 1883 by Ferdinand von Mueller who gave it the name Oncinocalyx betchei in the Southern Science Record, from specimens collected in 1883 near the Namoi River at Gunnedah by Ernst Betche.[3] [4] [5] In 2016, Stefan Kattari and Yasaman Salmaki changed the name to Teucrium betchei in the journal Taxon.[6]
Teucrium betchei grows in grassy woodland and on disturbed sites, mainly on the North West Slopes of New South Wales and the Darling Downs of south-eastern Queensland.
