GOT. Navbau, R. Belgische Sphagnum Vormen. [Belgian forms of Sphagnum.] Bull. 

 Cercle Sci. Anvers (Tijdschr. Wetensch. Kring Antwerp.) 12: 39^3. 1920. — The author 

 comments on the polymorphism of the genus Sphagnum and discusses 21 varieties, forms, and 

 subforms of various species, which are known at present from Belgium only. Most of these 

 were recognized by Warnstorf in his "Sphagnologia universalis" of 1911. — A. W. Evans. 



608. Nicholson, William Edw.\rd. New and rare British hepatics. Jour. Botany 59: 

 202-204. 1921. — The author gives notes on Riccia Huebeneriana Lindenb., Cephalozia spini- 

 flora Schiffn., and Cephaloziella elachista (Jack) Schiffn. var. spinigera (Lindb.) K. M. — 

 S. H. Burnham. 



609. Pearson, Wm. Hy. Notes on a small collection of hepatics from Oregon. Bryologiat 

 24: 21. 1921. — This is a list of 10 species with descriptive notes, based on a collection made 

 by C. Potter within the city limits of Portland, Oregon. — E. B. Chamberlain. 



610. PoTTiER, Jacques. La parente des Andreacees et des hepatiques et un cas teratolo- 

 gique qui la confirme. [The relationship of the Andreaeaceae and the hepatics and a terato- 

 logical case that confirms it.] Bull. Mus. Hist. Nat. [Paris] 26: 337-344. 8 fig. 1920.— The 

 species of Andreaea and of certain hepatics have been confused in the past because of similar- 

 ities of aspect and structure. The structures developed on the germination of the spores of 

 Andreaea are more reminiscent of the hepatics than of the mosses. The development of the 

 leaf of the Andreaeaceae resembles that of the Jungermanniaceae and not that of the mosses. 

 The pseudopodium, which also occurs in the Sphagnaceae, has its analogue among the hepatics. 

 The greatest point of resemblance between the 2 groups, however, is the opening of the capsule 

 by 4 valves. In the subgenus Acroschisma of Andreaea these valves separate quite to the 

 summit of the capsule, as is usual in the hepatics. An abnormal leaf of Andreaea angustata 

 with 2 lobes is described and compared with the normal leaves of certain hepatics. This re- 

 semblance is not only superficial but extends to the anatomical structure. Especially striking 

 is the resemblance between Andreaea petrophila and Herberta adunca. The various points 

 of similarity between the Andreaeaceae and the hepatics would seem to indicate an indirect 

 relationship. — E. B. Payson. 



611. Theriot, I. Considerations sur la flore bryologique de la Nouvelle-Caledonie et diag- 

 noses d'especes nouvelles. [Remarks on the bryological flora of New Caledonia and diagnoses 

 of new species.] Rev. Bryologique 47: 69-71. 1920. — In the 1st part of this article, which is 

 to be continued, the author reviews the work which has been done on the mosses of New Cale- 

 donia and estimates that the number of species occurring on the island is approximately 500. 

 In the 2nd part he begins the discussion of a collection made by I. Franc, citing Trematodon 

 paucifolhcs C. M. from New Caledonia for the 1st time and proposing Holomitrium Franci as 

 a new species. — A. W . Evans. 



612. Theriot, I. Une rectification a propos du Stereodon lignicola Mitt. [A correction in 

 regard to Stereodon lignicola Mitt.] Rev. Bryologique 47: 71-72. 1920. — It is shown that. S'iere- 

 odon lignicola of India was based on 2 distinct species. The 1st is an Isopterygium and may be 

 known as /. lignicola (Mitt.) Jaeger; the 2nd is a Setnatophyllum, too fragmentary for deter- 

 mination, although probably undescribed. — A. W. Evans, 



613. Warnstorf, C. tJber einige Arten aus der Gattung Calypogeia Raddi sensu Nees. 

 [On certain species of Calypogeia.] Hedwigia 62: 1-11. 1920. — The author calls attention to 

 the confusion which still prevails regarding the specific limitations of Calypogeia Trichomanis 

 (L.) Corda and certain other members of the genus, and records a series of observations based 

 largely on the specimens distributed by V. Schiffner in his "Hepaticae europaeae exsiccatae." 

 He reaches the conclusion that C. Neesiana (Massal. & Carest.) K. Miill. is not specifically 

 distinct from C. Trichomanis, the one passing into the other by insensible intergradations. 

 In his opinion the specimens distributed by Schiffner under the name C. paludosa Warnst. 

 do not represent that species but belong instead to C. trichomanoides Warnst. The true C.
