Die von Kern er und später von v. Wettstein als getrennte 

 Arten aufgeführten Melampyrum commutatiim Tausch =-- M. vulgatiim 

 Fers, und M. pratense L. stellt Verf. als (durch Uebergänge verbundene) 

 Typen von M. pratense L. a. vulgatiim (Pers.) und ß. integerrimum Doli, 

 auf. Nach der Kerner- v. We 1 1 s t e i n'schen Ansicht ist die Benennung 

 „pratense"' für den erstgenannten Typus ungeeignet, weil dieser im 

 mittleren Europa nicht auf Wiesen vorkommt. Wahrscheinlich bezieht 

 sich aber nach Verf. Linne's „pratense"' auch auf diese Form (vulga- 

 tiim) die in Schweden oft auf Waldwiesen und ähnlichen Localitäten 

 wächst. 



Von den im südlichen und mittleren Schweden angetroffenen 

 Formen von Alchimilla vulgaris L. (coli.) giebt Verf. ausführliche Be- 

 schreibungen. 



Auch verschiedene andere Formen werden m. o. w. eingehend be- 

 handelt. Grevillius (Kempen a. Rh.).

The Culm Measures of Devonshire have been generally 

 regarded as rocks of Lower Carboniferous age, and as largely, 

 if not entirely, equivalent to the Culm of Germany^ Austria 

 and elsewhere on the Continent; the latter series undoubtedly 

 belonging to that period as the evidence of both its flora and 

 fauna demonstrates. This paper, however, shows that v\"hile 

 a small portion of the Culm Measures of Devon (the Lower 

 Culm Measures) is no doubt equivalent in age to the Continental 

 rocks, the great bulk of the series, vvhich belongs to the Upper 

 Culm Measures, is of Upper Carboniferous age, and is homo- 

 taxial with the Coal Measures in other British areas. In De- 

 vonshire , there is very little coal, and it has been found 

 that w^eil-preserved plant remains are very rare. A number of 

 specimens have, however, been obtained from the one horizon^ 

 on which an impure smutty coal, known locally as culm, occurs 

 in N.-W, Devon. These have proved to be a typical Middle 

 Coal Measure flora. 



Among the species described and figured are Calamites 

 {Calamitina) iindulatus, Sternb., Alethopteris Serli (Brong.), 

 A. lonchitica (Schi.), including a variety in which the pinnules 

 are not decurrent, Urnatopteris tenella (Brong.), Lepidodendron 

 fusiforme (Corda) and Sigillaria tessellata Brong. Other spe- 

 cimens mentioned are Anmilaria galioides (L. and H.), Cala- 

 mostachys longlfolia Weiss, Renaultea footnerl (Marrat), R. 

 ochatzlarensis (Stur), and Lepidophloios acerosiis (L. and H.). 

 Two plants, new to Britain, are described in Neuropterls Schle- 

 hani Stur., and Megalopteris Sp.? 



The concluding portion of the paper deals with the geo- 

 logical aspect, especially the evidences which these plants 

 present as to the age of the beds. Arber (Cambridge)
