der letzteren vermag Verf. zu einem abschliessenden Urteil nicht 

 zu gelangen, wenn er auch der Ansicht zuneigt, dass die äusserst 

 zahlreichen fruchtbodenständigen Papillen die Aufgabe haben, In- 

 sekten als Bestäubungsvermittler anzulocken. 



Verf. schildert dann die geographische Verbreitung (West- 

 Australien) sowie die verwandtschaftlichen Beziehungen und 

 schliesst mit der Diagnose der einzigen Art C. follicularis Labill. 

 Eine systematische Verwandtschaft der Cephalotaceae mit den Sar- 

 raceniaceae erkennt Verf. nicht an; er ist geneigt der Gattung eine 

 selbständige Stellung zwischen den Saxifragaceae und den Crassu- 

 laceae, jedoch mit engeren Beziehungen zu der letzteren Familie, 

 anzuweisen. Leeke (Neubabelsberg). 



Ostenfeld, C. H., Anemone- og Kobjaelde- Arternes Ud- 

 bredelse i Danmark [English Abstract: The Distribu- 

 tion within Denmark of the Species oi Anemone, Hepa- 

 tica and Pulsatilla}. (Biol. Arb. tilegnede Eug. Warming. Köben- 

 havn, 1911. p. 241-263. 1 fig. 2 maps.) 



Based upon numerous detail-observations, the author gives the 

 distribution within Denmark of the species oi Anemone, Hepatica 

 and Pulsatilla; further short notes on their general distribution 

 and remarks with regard to the time and the route of their post- 

 glacial immigration into Denmark. 



Anemone nemorosa is, practically distributed over the whole 

 country, while A. ranunculoides is restricted to the islands and the 

 south-eastern part of Jutland, Hepatica triloba has much the same 

 area as the latter, but extends farther northwards in Jutland. 

 Anemone apennina occurs in several of the small woods in the 

 island of Bornholm, and always in a pale-flowered form (var. 

 pallida Lange, Syn. A. coerulescens Lange); the author suggests that 

 it has been introduced by man, but no exact data bearing upon the 

 question exist. With regard to the three other species, A. nemorosa 

 is supposed to have immigrated at an early time, when the country 

 became covered by forest, Hepatica a little later, and A. ranuncu- 

 loides still later, most likely in the so-called Oak-period. 



Pulsatilla vernalis is a rare plant in Denmark, it has onl}' 

 been found in three areas of Jutland, and the author is of the 

 opinion that it is an early immigrant into Denmark, arriving 

 already in the cold and rather Continental pine-period; now it only 

 survives in a few favourable localities where the deciduous woods 

 have not destroyed it. It has its western lowland limit of distribu- 

 tion in Denmark. 



Pulsatilla pratensis occurs in the Danish islands and in two 

 areas of Jutland, while P. vulgaris inhabits just the other part of 

 the country, the two species having a mutually exclusive distribu- 

 tion, in spite of that they grow on nearly the same kind of soil 

 (diluvial sand). No explanation of this fact has been found. P. pra- 

 tensis is an eastern species with western limit in Denmark, P. 

 vulgaris is a western one. It is supposed that P. pratensis has come 

 from Sweden and in a relatively late time, while P. vulgaris has 

 immigrated from the south and earlier. The distribution of the 

 three first named anemones and the two last named Pulsatillae is 

 given in two Charts. C. H. Ostenfeld.
