268 The Upper Cretaceous Floras of the World 



described a single species from this area and in 1853 Miquel ' published 



an account of the plants from beds of this age in Limburg, and Bosquet 2 



in 1861 and 1866 listed the plants from Limburg and the adjacent region 



in Belgium. Nothing further has appeared except a short paper by 



Lange 3 in 1890 who described a collection of Aachen plants in the 



Leipzig Museum which had been presented to Sehenk many years before 



by Debey. 



Combining the very uneven and for the most part unsatisfactory work 



of these various students results in the following list of species : 



JEcidites stellatus Debey and Ettingshausen 



Adiantites cassebeeroides Debey and Ettingshausen 



Adiantites decaisneanum Debey and Ettingshausen 



Araucarites miqueli Debey 



Asplenium brongniarti Debey and Ettingshausen 



Asplenium cunopteroides Debey and Ettingshausen 



Asplenium fwrsteri Debey and Ettingshausen 



Belodendron gracilis Debey 



Belodendron lepidodendroides Debey 



Belodendron neesii Debey 



Benizia calopteris Debey and Ettingshausen 



Bonavcnturea cardinalis Debey and Ettingshausen 



Bowerbankia attenuata Debey 



Bowerbankia emarginata Debey 



Bowerbankia maxima Debey 



Bowerbankia rcpanda Debey 



Bowerbankia rotundifolia Debey 



Carolopteris aquensis Debey and Ettingshausen 



Carolopteris asplenioides Debey and Ettingshausen 



Carpolithus hemloeinus Schlotheim (= Sequoia sp.) 



Caulerpites bryoides Debey and Ettingshausen 



Caulinia mulleri Pomel
