Teucrium disjunctum is a species of flowering plant in the family Lamiaceae and is endemic to inland Australia. It is an erect, openly-branched, hairy, greyish-white shrub, usually with egg-shaped to elliptic leaves, and white flowers arranged singly in leaf axils.
Teucrium disjunctum is an erect, openly-branched shrub that typically grows to a height of 0.3–0.8 m (1 ft 0 in – 2 ft 7 in). Its branches are square in cross-section, greyish-green and covered with branched hairs and sessile glands. The leaves are egg-shaped to elliptic, 15–25 mm (0.59–0.98 in) long, 3–5 mm (0.12–0.20 in) wide, sessile and covered with greyish-white hairs. The flowers are arranged singly in the axils of leaf-like bracts near the ends of the stems, each flower sessile or on a short pedicel. The sepals are 3–3.5 mm (0.12–0.14 in) long, joined at the base for about 1 mm (0.039 in) with narrow triangular lobes. The petals are white, 8–12 mm (0.31–0.47 in) long, the lowest lobe 1.5–2 mm (0.059–0.079 in) long. Flowering occurs in most months with a peak from May to November and the fruit is spherical, glossy orange-red and 3–4 mm (0.12–0.16 in) in diameter.[2]
Taxonomy
This species was first formally described in 2014 by Kevin Thiele and Kelly Anne Shepherd and given the name Spartothamnella canescens in the journal Nuytsia.[2][3] In 2017, Thiele and Shepherd changed the name to Teucrium disjunctum in a later edition of the same journal.[4][5] The specific epithet (disjunctum) means "separate, distinct", referring to the three disjunct populations of this species.[5]
