VON Ettingshausen. — Fossil Flora of Neio Zealand. 241 



may refer the above-mentioned localities to the Upper Cre- 

 taceous formation. 



I. Pakawau, Nelson, the richest locality of the four, con- 

 taiiis well-preserved fossil plants. Its flora is characterized 

 by species of ferns exhibiting the facies of Cretaceous ferns ; 

 by the genera of Coniferos, Podocarjnmii and Dacrydinium ; 

 by a peculiar genus of Musaceae, Haastia, related to Muso- 

 phyllum; by IJlmopliylon, a genus comprising the ancestor- 

 species of Tertiary Ulmus- and P/a;zcra-species ; by a Dryo- 

 phyllum, and by a Greiciopsis — species analogous to species of 

 the American Cretaceous formation ; and by species of Cin- 

 naviomura and Dryandroides, corresponding to European Cre- 

 taceous species. There have also been found a Bamhiisea, a 

 Casuarinites, a peculiar i^a^/ws-species, and a Cupanitcs. 



II. Grey River, Westland, a locality which offers many 

 but not such well-preserved fossils. There have been dis- 

 covered a Flabellaria, related to F. longirJiachis, Ung., from 

 the Cretaceous beds of Muthmannsdorf, Austria ; two species 

 of Qucrcus, one species of Celastrophyllam, and one species of 

 PalcBOcassia, all corresponding to species of the Cretaceous 

 flora; a Dalhergiophyllum reminds us of a Dalberrjia-species 

 of the same flora. There also have been found a Kiiightio- 

 phyllum and a Ccratopetaluvi, both peculiar to this locality ; 

 whilst a Bavihusca, a Casuarinites, and a Cupanitcs, which 

 also occur at the former locality, have been collected. 



III. Wangapeka, Nelson, showing a flora which agrees 

 with that of the preceding localities, inasmuch as some of its 

 species are common to the latter. Of the several forms of 

 fossil plants peculiar to this locality, the following are worthy 

 of notice : Two genera of Coniferae, the one intermediate be- 

 tween Cephalotaxus and Torrcya, the other uniting Ginkgo 

 v,ith Phyllocladus ; two Qucrcus-, one Fagus-, and one Ficiis- 

 species, all corresponding to Cretaceous forms ; a Sapindo- 

 phyllum analogous to Sapindus prodromus, Heer, from the 

 Cretaceous strata of North Greenland ; a Dalbcrgiopliyllum, 

 and a Poacites. 



IV. Reefton, Nelson. Only Casuarinites (Cretaceous) has 

 been found here, a species which also occurs at Pakawau and 

 at Grey River. 



Trias. 

 The collections of Sir Julius von Haast and Professor 

 Parker also contain many fossil plants from localities which 

 I refer to much lower Mesozoic strata. They are — Mount 

 Potts, Haast Gully, Malvern Hills II., Mataura, and Wai- 

 kawa. A greater difference of age of these localities is ex- 

 cluded by some common species which they contain. The 

 species mostly are analogous to Triassic ones. I may there- 

 fore not be far wrong in supposing that all the last-named 

 localities belong to the Trias formation.
