to original drawings or from bryological works. Series I : Selection of illustrations from Loe- 

 ske's "Mosses of Europe." 40 pi. Max Lande: Berlin-Schoneberg, 1918. — The present 

 fascicle is the initial number of a series in which it is planned to illustrate a wide selection 

 of mosses. The 40 plates were all drawn from European specimens and represent SO species 

 belonging to 36 genera. The figures were mostly prepared by P. Janzen and show individual 

 plants, leaves, and capsules, as well as numerous anatomical details. In connection with 

 each plate, full data are supplied regarding the figures, and the sources of the specimens used 

 in the preparation of the drawings are likewise definitely given. Otherwise there is no de- 

 scriptive text. — A. W. Evans. 



878. HoLziNGER, John M. Notes [on Physcomitrium pygmaeum]. Bryologist 24: 26-27. 

 1921. — The article consists of 2 notes supplementary to a paper by Elizabeth G. Britton. 

 The 1st note states that Physcomitriwn pygmaeum is probably autoicous and adds details 

 regarding spores; the 2nd note records a new station in Minnesota, based on material 

 collected by J. H. Sandberg, and establishes definitely the autoicous inflorescence of the 

 species. — E. B. Chamberlain. 



879. PoTTiER, Jacques. Recherches sur le developpement de la feuille des mousses. 

 [Studies on the development of the leaf in mosses.] 25 X 61 cm., viii + 144- P-, 32 pi. Impri- 

 merie Durand: Chartres, 1920. — The author first gives a critical account of the work pre- 

 viously done on the development of moss leaves, beginning with an article by Morren, 

 which appeared in 1840. His own investigations were made on serial microtome sections, and 

 in several cases reconstructions of young leaves in plastiline were prepared. The mosses 

 studied included the following species, representing various natural groups: Andreaea crassi- 

 nervia, A. angustata, Mnium undulatum, M. punctatum, Funaria hygrometrica, Dicranum 

 scoparium, Atrichum undulatum, Barbula ruralis, and Leucobryum glaucum. Andreaea 

 crass inervia and Mnium undulatum are described and figured in great detail, and plastiline 

 models of leaves in various stages of development are shown in photographic reproduction. 

 The other species are treated more briefly. As a result of his studies the author draws the 

 following conclusions: (1) A moss leaf grows by means of an initial cell only at the beginning 

 of its development; (2) the region of active cell division, in the course of the ontogeny of the 

 leaf, is shifted from the apex to the base; (3) the apex is differentiated very early; (4) in certain 

 species of ylndreaeawithcostate leaves, the initial cell sometimes shows 2 cutting faces, as 

 in the more highly evolved mosses; (5) m Mnium punctatum, the leaf-margins are not compar- 

 able with the nerve in their development; (6) groups of "st6nocystes" (auxiliary cells) in the 

 nerve do not always originate in the same way; (7) Leucobryum glaucum shows an asymmetry 

 in its leaves, agreeing in this respect with the other mosses. — A. W . Evans.

880. Beeli, M. Note sur le genre Meliola Fr. Especes et varietes nouvelles recoltees au 

 Congo. [Rote on the genus Meliola Fr. New species and varieties collected in the Congo.] 

 Bull. Jard. Bot. Etat [Bruxelles] 7 : 89-160. 1920. — A general synopsis of the species of Meliola 

 based on morphological characters and host relationships is given. A number of new species 

 and new varieties are described. A new genus, Meliolinopsis, is founded for species with 

 cylindrical, persistent, 8-spored asci, the type species being given as M. megalospora (Rehm) 

 Beeli. The 2 genera, Meliola and Meliolinopsis, are recognized, the former being subdivided 

 into the sub-genera Meliolina, Irene, and Meliolaste. An analytical key to genera and sub- 

 genera is given. — Henri Micheels.
