Ourisia sessilifolia

Ourisia sessilifolia is a species of flowering plant in the family Plantaginaceae that is endemic to high-elevation habitats in the South Island and Stewart Island of New Zealand. Joseph Dalton Hooker described O. sessilifolia in 1864. Plants of this species of New Zealand mountain foxglove are perennial, small-leaved, rosette herbs that are covered in a mixture of short glandular hairs and long non-glandular hairs. They have hairy, crenate, ovate leaves that are in a basal rosette. The flowers are in pairs or whorls in each node, with a and regular calyx and a white regular corolla. The corolla tube is purple inside, with one or three lines of white hairs inside, and purple outside. It is listed as Not Threatened.

Description

Ourisia sessilifolia plants are perennial herbs. The stems are creeping, with opposite leaves that are tightly packed into rosettes or subrosettes. Leaf petioles are 3.9–29.8 mm long. Leaf blades are 12.2–59.1 mm long by 9.7–44.5 mm wide (length: width ratio 1.1–1.5: 1), usually ovate to very broadly ovate, widest below the middle, with a rounded apex, cuneate base and regularly crenate edges. Leaves are densely hairy with a mixture of short glandular hairs and longer non-glandular hairs on both surfaces, especially on the prominent veins on the lower surface. Inflorescences are erect, with hairy racemes (sometimes densely hairy) up to 202 mm long, with a mixture of glandular and non-glandular hairs, and with 2–5 flowering nodes and up to 10 total flowers per raceme. Each flowering node has 1–4 flowers and 2 sessile, sometimes clasping bracts that are oblanceolate to narrowly obovate or narrowly elliptic. The lowest bracts are similar to the leaves, 11.6–18.6 mm long and 4.4–12.2 mm wide, and become smaller toward the apex of the raceme. The flowers are borne on a densely hairy pedicel that is up to 19.5 mm long and usually has a mixture of non-glandular and glandular hairs. The calyx is 6.3–10.4 mm long, regular, usually with all lobes equally divided to the base, and often densely hairy with a mixture of glandular and non-glandular hairs. …
