The earliest conifer

ANDREW SCOTT

Botany Department, Birkbeck College, Malet Street, London WC1E 7HX, UK

SMALL leaves and a leafy shoot from the Low Westphalian B (Upper Carboniferous) near Wakefield, Yorkshire, represent the oldest direct evidence for the existence of the order Coniferales (conifers) yet discovered. This material is preserved both as compression fossils and as charcoal.
