 species). N*^ I. (Journ. and Proc. Roy. Soc. New South Wales. 

 IL. 3. p. 463—513. April 1916.) 



The paper begins with biological and morphological observa- 

 tions especially on the extrafloral nectaries of Acacias and on the 

 funicle and arillus. The following new species are described: A, 

 Carnei, A. Mabellae, A. Flocktoniae, A. Chalkeri, A. Kettlewelliae, A.

In the Summer of 1895, a highmoor field near Herning in 

 Jutland was sowed with grass and has since then remained unalt- 

 ered; it was manured in some years, grazed off or cut every year. 

 Originally, it was sown with the following species: Trifolium pra- 

 tense, T. hyhridum., T. repens, Loliuin perenne, Phleum pratense, 

 Alopecurus pratensis, Dactylis glomerata, Poa trivialis. Now, 20 years 

 after, all these species were still there, but in a ratio different from 

 the original, f. inst. Trifolium pratense was very scarce, T. repens 

 luxuriant. 



Different spontaneous plants had appeared , of which the fol- 

 lowing were of importance: Festuca pratensis, Poa pratensis, 

 Festuca rubra, Holcus lanatus, Agrostis vulgaris, Vicia cracca, Ta- 

 raxacum sp. 



20 samples of 0,25 m^ were taken in this field. Their contents 

 are tabulated, the percentage ofweight being given for each species.

Miehe, H,, Bemerkungen über epiphytische Vegetation. 

 (Naturwiss. Wochenschr. N. F. XV. N^ 41. p. 591—592. 1 Fig. 1916.) 

 Diese Vegetation erreicht in den Tropen ihre eigentliche Ent- 

 wicklung. Gegenden im feuchten Klima und warmen Winter zeigen 

 auch in Europa eine epiphytische Vegetation, z.B. lebt Po/>'/)o<^mm 

 vulgare auf den Aesten der Eichen bei Varel jn Oldenburg. 

 Wie in den Tropen Vögel und Affen die kleinen Samen von Ficus 

 elastica mit ihrem Kote auf die Bäume verschleppen, ebenso ge- 

 schieht dies bei Sorbus, Sambucus, Amelanchier etc.
