Leucadendron spirale (Salisb. ex Knight) I.Williams

Wolseley Conebush, Spiral Chasme


Family: Proteaceae

Genus: Leucadendron

Description: 

From Cult. Prot. (plant://CasmSpir]) A small shrub about three feet high, discovered near Breede Rivier, by Mr. J. Niven... Leaves all linear-attenuated, bearded and spirally imbricated while young. Scales of the Cone incurved, shining near their margin.

From ProteaWorldOnline [quote: As far as is known the plant is extinct, but some populations may still lurk in the Worcester Valley.

The species was collected in 1801 and 1819 from "Breede River". From this population it was grown in the United Kingdom, where Richard Salisbury (1809) noted that "cuttings grow freely, but possessing little beauty it should only be admitted in extensive collections"... It was again collected from "Wolseley:" in 1933 in "Heath, containing only few species, but river ground and swampy ground, few hours only". It has not been seen since. The plant has needle-like, rough, leaves 4-9mm long. The male flowerheads are 6-8 mm long and do not have floral bracts - they probably liberate clouds of pollen if knocked while flowering. The female plants produce seed-bearing cones: these form hard balls about 20 mm round. It is closely related to the Strawberry Conebush, which has longer leaves, and bigger, red cones. It probably flowers in summer.]
