Tamworth |}} Euphrasia ruptura (former synonym: Euphrasia sp. Tamworth) is a presumed extinct plant from the genus Euphrasia (eyebrights) within the family Orobanchaceae (formerly Scrophulariaceae). It was first described in 1997 by William R. Barker from a single collection made in the Tamworth Area, Northern Tablelands, New South Wales in 1904. It is named after the Australian botanist Herman Montague Rucker Rupp who discovered this species. DescriptionThis perennial subshrub reaches a height of at least 26 centimetres. The branchlets are covered with hair and have 22 to 25 leave pairs. The length of the calyx reaches from 3.8 to 4.5 millimetres. The corolla measures from 8 to 10.8 millimetres. The color is unknown. The tube is about five millimetres long and the stamens with the anthers 0.9 x 1.7 millimetres. StatusThis plant is only known from two flowering branches collected in September 1904 in the North Western Slopes near Tamworth.
