625. Luisier, A. Les mousses de Madere. [Mosses of Madeira.] Broteria Ser. Bot. 

 17: 112-142. 1919. — This article is the sixth of a scries covering a complete discussion of 

 Madeiran mosses and includes the genera Bryum (in part) to Thamnium. No mw forms are 

 described, but short notes, references, and reprints of original descriptions are appended to 

 many of the species mentioned. More extended and critical discussions occur for liryum 

 serrulatum Card., Pogonatum subaloides (C. M.) Jaeg., Neckera intermedia Brid., and the 

 species of Lcucodon and of Echinodium. — Edward B. Chamberlain. 



626. Melin, Elias. Sphagnum angermanicum n. sp. Svensk. Bot. Tidskr. [Stockholm] 

 13: 21-25. S fig. 1919. — Under the above name the author describes and illustrates a new 

 species of Sphagnum which he found in Angermanland, .Sweden, in 1915, 1916 and 1917. It 

 is related to S. molle Sulliv.— IT. W. Gilbert. 



627. Paul, H. Einige fur den Bayerischen Wald neue Pflanzen. [Plants new to the 

 Bavarian Forest.] Mitteil. Bayer. Bot. Ges. Erforsch. Heim. Flora 3: 467-168. 1918.— The 

 author lists the following four plants as additions to the known flora of the Bavarian Forest: 

 Scutellaria minor L., Sphagnum subbicolor Hpe., Bryum cyclophyllum Br. Eur., and Cathar- 

 inaea Hausknechlii Broth. He describes the exact localities where these plants were found 

 and ^numerates various other species, both spermatophytes and bryophytes, which grew in 

 association with them. — A. W. Evans. 



628. Potier de la Varde, R. Observations sur quelques especes du genre Fissidens. 

 [Observations on certain species of the genus Fissidens.] Rev. Bryologique 41: 85-92. PI. 1. 

 1914. [Issued in 1919.] — In the first part of this paper (which is to be continued) the value of 

 apparent dioecism as a specific character in the genus Fissidens is discussed. This condition 

 is brought about when the same protonema gives rise to distinct male and female shoots. It 

 thus represents a special form of monoecism, and the student of mosses is cautioned against 

 attributing positive dioecism to a species until the protonemal relations have been estab- 

 lished. In the second part of the paper the status of F. tamarindifolius Wils. is considered, 

 and the conclusion is reached that it represents a form of F. inconsians Schimp. This con- 

 clusion is based on the study of a long series of European specimens ranging from England to 

 Italy and the Tirol. The figures were drawn from material collected in the department of 

 the Manche in France. — A. W. Evans. 



629. Seymour, M. E. Mosses of the Cascade Mountains, Washington, collected by J. A. 

 Allen. Bryologist 22: S5-86. 1919. — This is a list, without comment, of the specimens 

 issued in the somewhat uncommon set of exsiccati mentioned in the title. — Edward B. 

 Chamberlain.

630. Adams, J. F. The alternate stage of Pucciniastrum Hydrangeae. Mycologia 12: 

 33-35. 1920. — Along a path about which hydrangeas and hemlocks were numerous, Hydrangea 

 arborescens was found to be heavily infected with Pucciniastrum Hydrangeae while the hem- 

 locks were infected with a Peridermium stage resembling P. Peckii. Inoculation with accio- 

 spores on Hydrangea arborescens grandiflora proved successful, mature uredinia appearing 

 in about 12 days. Three other species of cultivated hydrangeas and a species of Vaccinium 

 failed to show infections. Because of differences in hosts and in morphology, the Perider- 

 mium is considered distinct from P. Peckii and is technically described, the name P. 

 Hydrangeae (Berk. & Curt.) comb. nov. being proposed. — H. R. Rosen.
