Cephalozia elachista.* — P. Culmanu has carefully re-examined a 

 specimen from Marais de Lossy near Geneva, in Herb. Bernet, which 

 had been named Cephalozia elachista by Bernet, but was renamed 

 G. lunulifolia by Ch. Meylan last year. Culmann's suspicion that Bernet 

 was right and Meylan wrong was well founded, for the specimen contains 

 a small quantity of the true C. elacliista, which therefore is, as Bernet 

 stated, a member of the French flora. Also mixed with this species 

 there is a considerable quantity of another species of Cephalozia, 

 probably the plant which Meylan referred to C. luaulifolia. It belongs, 

 however, rather to C. connivens, according to Culmann, because of the 

 large leaf-cells, dentate cihate calyx, and quadrilobed bracts ; but unless 

 the inflorescence can be proved to \)q monoicous, the determination is 

 not absolutely sure. 



Development of Sporogoniuin of Notothylas.t — "VV. H. Lang pub- 

 lishes the results of a study of the sporogonium of Notothylas, undertaken 

 with a view to clearing away some of the discrepancies between the 

 investigations of Leitgeb and those of later workers, especially concerning 

 the degree of development att^iined by the columella. The material 

 examined was collected at Singapore by the author, and is referred to 

 N. Breutelii. He finds that the embryogeny conforms to the usual type 

 for the Anthocerotacete, but that the endothecium, instead of being 

 devoted to the formation of a sterile columella, forms sporogenous 

 tissue for the greater part of the intercalary growth of the sporogonium ; 

 in a considerable proportion of cases, however, it produces sterile tissue 

 towards the close of development. The potentially sporogenous nature 

 of the endothecium in this form of JSf. Breutelii leads to various specula- 

 tions. For instance, the sterile columella in other Anthocerotacete was 

 originally the spore-producing tissue, and the amphithecial archesporium 

 is of secondary origin.
