About Haastia sinclairii Hook.fil.
Haastia sinclairii Hook.fil. is a prostrate small green plant, with a single stem and leaves arranged in slightly spiraling circles around the stem, bearing a white flower that may have orange or yellow petals along its outer rim. In 1961, Allan published a more detailed description of this species: the plant is sparingly to heavily branched, with growth ranging from decumbent to suberect. Branchlets reach approximately 30 cm in length and 4 to 6 mm in diameter. Leaves are roughly spreading, growing up to 3.5 cm long and 1.5 cm wide, shaped oblong-obovate, with apex ranging from subacute to rounded. Leaves are densely covered in whitish, subappressed tomentum, except on the adaxial surface of the appressed base; the upper portion of the leaf is slightly thickened and somewhat rugose, with 5 to 10 veins that anastomose on the upper leaf surface. Capitula measure approximately 3 cm in diameter, and the receptacle measures 5 to 6 mm in diameter. Phyllaries are narrow-oblanceolate, subacuminate, pilose on the abaxial surface, and approximately 1 cm long. Achenes are approximately 2 mm long, and narrow-linear. Pappus grows up to 1 cm long. This species is known to occur only in the South Island of New Zealand, where it grows in alpine and subalpine habitats, most commonly on scree fields.
