Aiitrophi/nm semicostatwn occnvved pockets of tissue, from each of which 

 protruded a brown egg of some insect. As the eggs were all empty, it 

 was not possible to determine the genus and species, nor did the material 

 show the developing stages of the pockets. The cells of the spongy 

 parenchyma press closely on the egg with broad surface, whereas other- 

 wise the inner leaf -cells develop excrescences : the development of the 

 cells is thus directly influenced by the insect egg. E. S. Gepp. 



Fern-hybrid Asplenium Ruta-muraria L. x septentrionale (L.) 

 HofFm.: A misinterpreted plant. — S. Mukbeck {Bot. Xolmr, 1910, 

 257-G2 ; see also Bot. Ceatralbl., 1918, 138, 69). The above 

 hybrid is described in detail, having been often wrongly diagnosed in 

 hterature. It is recorded from Sweden (Gestrikland, Medelpad), 

 Norway (Hardanger), and Tyrol (entrance to the Oetztal). E. S. G-. 



Contributions to the Flora and Plant-geography of Australia : 

 Part I., Pteridophyta, G-ymnospermse, Monocotyledonese. — K. Domin 

 {Bihliotli. Bot. Stuttgart, 191."), 85, .554, 117 figs, in text, 18 pis.; 

 see also Bot. Gentralbh, 1918, 138, 4-12). A report on the collections 

 made by the author in Queensland and X. S. Wales in 1909 and 1910. 

 The present part includes the Pteridophytes, treated systematically. 

 References to literature, figures, synonyms, geographical distril)ution in 

 general are given for each species, together with a complete record of 

 its Australian distribution. Endemic species are described. The author 

 expounds his views on the relationship of species, basing them on the 

 large mass of material collected. Important details are included con- 

 cerning the manner of life of the plants (height, frequency, substratum, 

 epiphytic growth, etc.), and their significance for mankind. The 

 systematic treatment is founded on the methods of Diels, Christ, and 

 Christensen's Index. Contrary, however, to the opinion of these 

 authors, the. genus Notholsena is united with Cheilanthes. The number 

 of new species of ferns is extraordinarily large. Eight species of 

 Lycopodiales are recorded, with old and new varieties. E. S. G. 



Remarks on Pteridophytes from Baden. — W. Zimmermann {Allg. 

 Bot. Zeitsch., 1916, 22,32-56 ; see also Bot. Gentralhl., 1918, 138, 26). 

 A preliminary list of new varieties and forms, to be followed by a 

 critical work on Baden Pteridophytes. Aspidiimi Filix-mas sub-var. 

 ursimcm is the name given to the German approximation-form 

 which has arisen in our latitudes, possibly from var. palmceam Moore. 

 Polijpndium disjnnctum Rupr. is no independent species, but merely a 

 shade-form (lus. disjunctum) of A. Robertianum Luerss. In the upper 

 Black Forest occurs a form of Aspidium Dryoptcris seeking shelter from 

 too great illumination (lus. insolatum). Aspidmm Fhegopteris var. 

 acutuin has acute pinnule-margins ; var. setoswn has xerophil tendencies. 

 A new luxuriant form, var. pulcherrimum of Asplenium Triclwmcmes, 

 occurs between Oberried and St. Wilhelm ; var. dubium of the same 

 species is probably a cross between var. typumni Luerss. and var. 

 pachgrachis Chr. New forms of Equisetum are also described.
