MORPHOLOGY AND TAXONOMY OF BRYOPHYTES 



Alexander W. Evans, Editor 



1205. Andrews, A. LeRoy. [Rev. of: Herzog, T. Die Bryophyten meiner zweiten Reise 

 durch Bolivia. (Bryophytes of second Bolivian trip.) Bibliotheca Botanica 87. 1916.] Bry- 

 ologist 23: 9-10. 1920. — The reviewer questions the author's tendency toward the multipli- 

 cation of new species and notes the slight value of the connection claimed to exist between 

 Bolivian and Mexican floras. The general phytogeographical discussions of the volume are 

 commended. — Edward B. Chamberlain. 



1206. Bryan, Geo. S. Early stages in the development of the sporophyte of Sphagnum 

 subsecundum. Amer. Jour. Bot. 7: 296-303. 26 jig. 1920. — Author reports the results of his 

 study of the young sporophyte dissected out from the venter of the archegonium. The fer- 

 tilized egg divides by a horizontal wall into two approximately equal cells, and a filament of 

 from 6 to 7 cells is usually formed before any longitudinal divisions occur. The division wall 

 in the 2-celled stage could not be traced with certainty in the older stages. Apical growth 

 probably occurs in the development of the young sporophyte. If the walls appear in regular 

 order, a long, slender type of sporophyte is produced; if in irregular order, a shorter, bulbous 

 type. The number of primary segments (formed by walls transverse to the axis of the arche- 

 gonium) has not been found to exceed 12. In a considerable number of cases disintegration 

 begins at the apical portion of the very young sporophyte and proceeds for some distance basi- 

 petally. The early development of the sporophyte of Sphagnum shows a greater similarity 

 to that of the Jungermanniales than to any other group of the Bryophyta. — E. W. Sinnott. 



1207. Familler, Ignaz. Die Lebermoose Bayerns. Zweiter (beschreibender) Teil. 

 [The Hepaticae of Bavaria. Second (descriptive) part.] Denkschr. Bayerischen Bot. Ges. 

 Regensburg 14: 1-167. 27 pi., 11 jig. 1920. — The first part of this comprehensive work on the 

 Hepaticae of Bavaria was published in 1917 (Denkschr. Bayer. Bot. Ges. Regensburg 13: 

 153-304. 5 jig.) and consisted of a compilation of the known stations for the various species. 

 The second part describes the species in considerable detail from independent observations, 

 giving a general idea of their habitats and of their distribution in Bavaria. Keys to the 

 genera and species are interpolated throughout, and every species is illustrated by one or more 

 photomicrographs, supplemented in a few cases by line drawings to bring out significant 

 features. In all 57 genera and 164 species are recognized, 22 species belonging to the Marchan- 

 tiales, 139 to the Jungermanniales, and 3 to the Anthocerotales. These relatively low numbers 

 are due to the author's broad conceptions of specific limitations. Instead of dividing a series 

 of closely related plants into species of subordinate rank, he defines the entire series as a
