Abstract
The taxonomical treatment of the Søby Flora is continued in this work. The present paper is the second of 3 publications in which the flora will be described and the environmental and climatic conditions interpreted. A detailed description of leaf architecture and cuticular anatomy is given on the following species: Jugans acuminata Braun, Juglans juglandiformis (Sternb.) Giebel (no cuticle preserved), Alnus julianaeformis (Sternb.) Kvacek et Holy, Castanea atavia Unger, Liquidambar europaea A. Braun, Ulmus pyramidalis Goeppert and Salix lavateri A. Braun sensu Hantke 1954.
Highlights
In 1969 a new fossil flora was found in a clay bed at the top of the Odderup Formation in the SS?)by-Fasterholt area
This paper is descriptive and concentrates on the taxonomy of the fossil plants. This description of th e fossil plants community, together with the geological observations, may create the basis for interpretation of th e environmental and climatic conditions shortly before the SS?)by-Fasterholt area was transgressed by the sea (Hodde Formation)
By careful comparison with descriptions and figures of fossils from other Tertiary floras it becomes probable that the leaves should be considered as leaflets from the composite leaf of Juglans acuminata Braun
Summary
In 1969 a new fossil flora was found in a clay bed at the top of the Odderup Formation in the SS?)by-Fasterholt area. The tertiary veins that arise on the admedial side of the secondaries and curve to join the midvein are forming an acute or right angle with the midvein. The upper epidermis has a thin cuticle and is composed of 190 to 250 cells per 0.1 mm2 The shape of the cells is isodiametric or slightly elongate and they are 18 to 38 microns long. Trichome bases are present in the upper epidermis They occur singly and are mainly confined to venation. Trichome bases are present in the lower epidermis They occur singly and they are found both over veins and in areoles. Fragments of hairs are sometimes found attached to the bases These fragments are funnelshaped, sometimes with transversal cell walls and they are all broken 15 to 20 microns above the base. The further nature of these hairs is not disclosed in the fossil material
