Torreya nicanica Krassilov (1967) from South Primorya differs considerably in having a short petiole and stomata which are arranged in rows. Several other Mesozoic species with Torreya-\\ leaves have been described. Torreya gracilis Florin emend. Harris (1979) from the Middle Jurassic of Yorkshire is of a similar size to T. detriti, but differs in having a short flat petiole, a flat leaf surface, much more elongate ordinary epidermal cells and a midrib marked by broader, rather than narrower, cells on the upper cuticle. Torreya valida Florin (1958) from the Middle Jurassic of Yorkshire has more elongate ordinary epidermal cells and much broader stomatal grooves than those of T. detriti. Torreya moelleri Florin (1958), from the Middle Jurassic of Bornholm, Denmark, has a much longer leaf and the stomata, which have fewer subsidiary cells, are arranged in rows. Torreya longifolia Gomolitzky (1964) from the Jurassic of central Asia has larger leaves with more elongate ordinary epidermal cells and stomata with fewer subsidiary cells. Torreyites carolinianus (Berry) Seward (1919), from the Middle Cretaceous of North Caro- lina, is of a similar size to T detriti but the description by Berry (1908) shows that the leaves taper much more gradually towards the apex and that the stomata tend towards transverse rather than longi- tudinal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Natural History Museum (London).
