The present paper is the second of a series of investigations into the anatomy of the lower Dicotyledons (1), aiming at the accumulation of anatomical data which, it is hoped, may prove of service in elucidating the phylogeny of the complex of orders usually regarded as situated somewhere near the base of the Angiosperm phylum. The continuance of the War has again materially retarded these investigations, and has also rendered it almost impossible to obtain material from abroad that would, doubtless, have been available in peace time. We are greatly indebted for substantial assistance in this relation more especially to Sir David Prain, F.R.S., Director of the Royal Botanic Gardens, Kew, and to Sir Frederick Moore, F.R.S., Director of the Glasnevin Gardens, Dublin, and to them we tender our grateful thanks.
