ZOOLOGY AND BOTANY, MICKOSCOPY, ETC. 537 



Haplomitrium Hookeri.* — F. Lilienfeld publishes some contribu- 

 tions to the morphology and biology of Haplomitrium Hookeri, large 

 quantities of whicli she found by a lake in the Carpathian Mountains. 

 Every stage of transition between the rhizome and the erect leafy shoots 

 was found. In feeble Ught the latter have very reduced leaves. The 

 apex of the rhizome has a dense covering of mucilaginous papillas, form- 

 ing as it were a root-cap. Parasitic and saprophytic fungi and endo- 

 phytic algai occui' in the rhizome. The capsule dehisces by a single 

 longitudinal slit. The antheridia occur all round the stem, especially in 

 the leaf -axils, 



Targionia.t — H. Deutsch publishes a morphological account of 

 Targionia Jtypophylla, illustrated with figures. He discusses the question 

 of putting Targionia and Cyathodium, and shows how utterly different 

 the two genera are in almost every point of structure. Hence Cyathodium 

 must seek other affinities, possibly with Corsinieae. 



Treuhia insigni8.|— L. Rodway records the occurrence of Treuhia 

 insignis in Tasmania. Discovered in Java in 1890, it was subsequently 

 found in Tahiti, Samoa, and New Zealand, and now has been gathered 

 in dense woods on the southern slopes of Mount Wellington. Rodway 

 gives a description of the morphology of the plant, and calls attention 

 to its interesting features — 1. The leaves or leaf-Uke expansions which 

 border the thallus. 2. The absence of the perianth, the function of 

 which is assumed by the enlarged fleshy calyptra. The New Zealand 

 form of the plant has been referred by Stephani to a distinct species, 

 T. bracteata. 



Capsule of Pellia.§ — T. E. Wallis calls attention to the dehiscence- 

 lines of the capsular wall of FeVia epiphylhi, and describes and figures 

 the mode of dehiscence. The lines become visible as the capsule changes 

 from dark green to brown ; and dehiscence starts at the equator, spreading 

 to the poles. The capsule is two-valved at first, and eventually four- 

 valved. 



Pellia epiphylla. || — P. Lesage publishes some biological notes on 

 Pellia epiphylla, and includes a record of the occurrence of two mature 

 sporogonia in the same involucre. One of his experiments was to detach 

 some nearly mature but still sessile sporogonia from the mother-plant 

 and to steep them in water ; an elongation of the seta in the normal 

 way took place, and the capsule dehisced. 



Pleurozia, Cephalozia, etc.f— V. Schiffner, continuing his bryo- 

 logical investigations, publishes the following notes : — (66) Gemmae of 

 Myurella julacea (with figure) ; (67) Cololejeunea echinata : (68) Dichiton
