Grevillea scortechinii
Grevillea scortechinii, commonly known as black grevillea, is a species of flowering plant in the family Proteaceae and is endemic to eastern Australia. It is a prostrate to sprawling shrub with serrated to pinnatifid leaves, the end lobes broadly triangular and often sharply-pointed, and clusters of brown flowers with a dark purplish-black style. There are two subspecies, subsp. scortechinii found in Queensland and subsp. sarmentosa, found in New South Wales.
Description
Grevillea scortechinii is a prostrate to sprawling shrub that typically grows up to high and wide. Its leaves are egg-shaped to oblong in outline, long and wide but serrated to pinnatifid with 3 to 14 lobes or broad teeth that are sometimes further divided, the end lobes rounded, to broadly triangular and up to long and sometimes sharply pointed. The lower surface of the leaves is silky-hairy. The flowers are borne on one side of a rachis long and brown, the style purplish black with a green pollen presenter. The flower stalk is long and the pistil long. Flowering time varies with subspecies and the fruit is a silky-hairy follicle long.Taxonomy
This grevillea was first formally described in 1883 by Benedetto Scortechini in the Proceedings of the Linnean Society of New South Wales from an unpublished description by Ferdinand von Mueller who gave it the name Grevillea ilicifolia var. scortechinii. In 1889, von Mueller raised the variety to species status as G. scortechinii in the Second Systematic Census of Australian Plants.In 1989, Donald McGillivray described two subspecies of G. scortechinii and the names are accepted by the Australian Plant Census:Grevillea scortechinii subsp. sarmentosa McGill., has leaf lobes that are often further divided, and lack conspicuous veins on the upper surface, the pistil long and the flower stalk long. Flowering occurs from February to March.Grevillea scortechinii F.Muell. subsp. scortechinii, has leaf lobes that are usually not further divided, and have conspicuous veins on the upper surface, the pistil long and the flower stalk long. Flowering occurs in October and November.
