rounds up, and finally is detached. Fertilization was not observed but the oospores were 

 observed to germinate and their growth followed for several weeks until the cultures were 

 lost through decay. At that time the filaments had reached the 3-celled stage. — L. I.

MORPHOLOGY AND TAXONOMY OF BRYOPHYTES 



Alexander W. Evans, Editor 



1032. Amann, J., and C. Meylan. Flore des mousses de la Suisse. [Moss flora of 

 Switzerland.] v. 1, 215 p., v. 2,5 + 4U p. PI. 1-12. L'Herbier Boissier: Geneva, 1918.— In 

 the second part the collaboration of P. Culmann is also acknowledged. Both parts bear the 

 separate date of 1912 and indicate Lausanne as the intended place of publication. The work 

 represents the first attempt at a comprehensive treatment of the mosses of Switzerland since 

 the appearance of Lesquereux's Catalogue des mousses de la Suisse in 1845. The first part, 

 aside from introductory suggestions for the study of mosses, is devoted to an original com- 

 bination of keys and descriptions for the identification of the Swiss mosses; it includes in 

 fact most of the species that have been proposed from all parts of Europe. Although in cer- 

 tain groups supplementary keys are given in the second part, this is primarily a "Bryogeo- 

 graphie," giving complete lists of localities of the Swiss species so far as known and includ- 

 ing the other European species in finer print with a general statement of the regions where 

 they are known to occur. Subspecies are designated as species of the second rank, a few 

 species of the third rank are likewise included, and a multitude of varietal forms are recog- 

 nized. Notes are often added calling attention to intergrading forms between species or to 

 other observations and opinions of the senior author or his collaborators. The following appar- 

 entlj r new species names are offered, the author in each case being Amann, unless otherwise 

 noted: Br yum albulanu?n, B. Baurii, B. callicarpum, B. Colombi Meylan, B. gypsophilum, 

 B. jamanense (reduced on a later page to a synonym of B. inflatum Phil.), B. juramim, B. 

 microcaespiticium, B. microlacustre (replacing B. parvulum Amann of an earlier page), B. 

 oeneiforme (on a later page apparently identified with B. Dixoni Card.), B. pallidocuspida- 

 tum, B. pseudo-Gracfianum, B. purpureo-aristatum, B. rosulatum (not C. Mull., 1856), B. 

 Ruedianum, B. scoticum, B. valesiacum, Ceratodon crassinervis (not Lorentz, 1866), Dicrano- 

 weisia intermedia, Dicranum latifolium (not Hedw., 1787), Eurhynchium nivium, Ptychodium 

 trisulcatum, Schislidium papillosum Culmann, Syntricia spuria and Trichostomum Fleischeri 

 Bauer. The first two plates deal with general matters helpful to moss-students; the others 

 illustrate species or forms which are new or not well understood. — A. LeRoy Andrews.

 36. 1919. — Spores sown on the surface of Marchal's solution produced protonemata which 

 were transferred singly by a needle to the surface of sterilized soil in pots. The resulting 

 single-spore cultures have been under observation for 2 years, and still remain uncontami- 

 nated by other mosses. Leafy axes are produced about eight weeks after germination, and the 

 first antheridia appear 4 to 6 weeks later. This species is strictly monoecious, the spores, 

 protonemata, and gametophores being bisexual in their potentialities. Synoicous inflores- 

 cences occur on about 14 per cent of the gametophores. Antheridia always appear before 

 arehegonia, and are typically produced on the apex of the primary axis of the gametophore, 

 with the arehegonia on lateral innovations. Other arrangements often occur. — G. S. Torrc.y.
