1261. Herzog, Th. Die Laubmoose der II. Freiburger Mulukkenexpedition. [The 

 mosses of the second Freiburg expedition to the Molucca (Spice) Islands.] Hedwigia 61: 

 286-299. PL 3, 7 fig. 1919.— The collections here reported upon were made by K. Deniger, 

 director of the expedition, and E. Stresemann, who accompanied him as zoologist. Most of 

 the specimens came from the islands of Ceram and Burn and from the Malayan peninsula. 

 The total number of species listed is 66, of which the following are described as new: Dicrano- 

 loma braunjelsioides from Ceram; Ctenidium moluccense and Hypnodendron caducifolium 

 from Buru; Ectropothecium serratum, Homaliodendron pinnatelloides, H. intermedium, and 

 Taxithelium Denigeri from the Malayan peninsula. Fifteen of the other species, which bear 

 Herzog's name as authority, had already been published in a paper dated 1916. In addition 

 several new varieties, forms, and combinations are proposed. The species illustrated are 

 Hymenodontopsis Stresemanii Herzog, the 2 new species of Homaliodendron, and H. flabella- 

 tum (Dicks.) Fleischer. — D. Reddick. 



1262. Holzinger, John M. On our American form of Timmia megapolitana Hedw. 



Bryologist 23: 86-88. Fig. 1-5. 1920.— The American specimens referred to Timmia mega- 

 politana are shown to differ from the European in several respects. The leaves, for example, 

 are less papillose and less serrate, the leaf-base is more hyaline, the antheridia are yellow, 

 and the calyptra remains attached. The actual status of the American plant is at present 

 undecided. — E. B. Chamberlain. 



1263. Holzinger, John M. Dixon and Watts on Antarctic mosses. [Rev. of: Dixon, 

 H. N., AND W. W. Watts. Mosses. Australasian Antarctic Expedition Sci. Rept. Ser. C. 

 7: 1-9. 1918 (see Bot. Absts. 7, Entry 1973).] Bryologist 23: 47. 1920.— The reviewer com- 

 mends the conservative tendency of the authors in their treatment of the genus Bryum.—E. 

 B. Chamberlain. 



1264. LoRCH, WiLHELM. Ubcr das Vorkommen von Calciumoxalatkrystallen in den 

 Sporogonien von Polytrichum commune L. [On the occurrence of crystals of calcium oxalate 

 in the sporogonia of Polytrichum commune.] Hedwigia 60: 342-349. 1919.— The presence of 

 crystals of calcium oxalate in the capsules of Polytrichum commune is reported. Other 

 species of Polytrichum examined failed to show them, and they have not been demonstrated 

 in any other bryophytes. The crystals are most abundant in the epidermal cells of the 

 spore-case but occur also in the columella, the walls of the spore-sac and the operculum. 

 In discussing the structure of the capsule certain dorsiventral peculiarities are emphasized.— 

 A. W. Evans. 



1265. LuisTER, A. Les mousses de Madere. [Mosses of Madeira.] Broteria Ser. Bot. 

 18: 99-120. 1920.— The present article (the ninth of the series) contains analytic keys to all 

 the families, genera, and species of mosses (through Fissidens), which occur in Madeira and 

 the adjoining islands. The keys incorporate brief descriptions and have references to the 

 author's previously published articles. [See Bot. Absts. 1, Entry 757; 3, Entries 2447, 2448; 

 6, Entry 156; 7, Entry 351.]— E. B. Chamberlain. 



1266. Machado, Ant6nio. Catalogo discritivo de Briologia Portuguesa. [Descriptive 

 catalogue of Portuguese mosses.] 143 p. Lisbon, 1919.— This catalogue lists all the species 

 and varieties of mosses occurring in Portugal. Of most species the author has seen authentic 

 material; in the remaining cases he cites authoritative records. To facilitate determina- 

 tions analytic keys based upon easily determined vegetative characters are included, and 

 each species or variety is characterized in 4 or 5 lines of description in the body of the work. 

 In all cases where fuller descriptions are not accessible in standard works, a foot-note gives 

 the original description in full. The total census, omitting varieties, shows 7 species of 

 Sphagnales, 4 of Andreaeales, and 313 of Bryales. The classification follows that of Dixon & 

 Jameson's Handbook. For each form there is a detailed statement of distribution for 

 Portugal, definite localities and collectors being cited without generalized statements. Fol- 

 lowing the catalogue there is a glossary, a page of errata, a page of addenda, and a complete
