Abstract
Abstract Populations of the leaf form-genus Taeniopteris Brongniart from two middle Mesozoic localities in New Zealand were studied. Attempts to obtain leaf cuticles from the little-metamorphosed deposits of the Huriwai Formation at Port Waikato were unsuccessful, and the affinities of taxa included within the form-genus in New Zealand remain unknown. The population of Taeniopteris at Port Waikato (topmost Jurassic), although variable, falls within the limits of the species T. daintreei McCoy, described from the Jurassic and lower Cretaceous in Eastern Australia. T. daintreei has been separated from T. spatulata McClelland (= Nipaniophyllum raoi Sahni) on anatomical grounds, and neither of the latter two names should be accepted for the Port Waikato leaves unless definite Pentoxylalean affinities were to be shown for them. T. daintreei (reported also from the Southland Temaikan) was not found in the Clent Hills and appears to be confined to middle Jurassic and younger beds in New Zealand. T. thomsoniana A...
