New Zealand Bryophytes.* — L. Cockayne gives a list of the mosses 

 and hepatics collected by him and by J. W. Murdoch in Stewart Island, 

 New Zealand, during October r.)()8. Stewart Island is extremely rich 

 in Bryophytes and Lichens, and the list represents but a tithe of the flora. 

 It contains thirty-five hepatics determined by F. Stephani. and thirty- 

 four mosses determined by Y. F. Brotherus. 



Adalbert Geheeb. f— J. Roll writes some sympathetic reminiscences 

 of Adalbert Geheeb (b. 1842 ; d. 1909), an apothecary at (ieisa. in the 

 department (Kreis) of Eisenach, and a bryologist of the highest rank. 

 He is well known by his prolonged bryological investigations in the 

 Rhongebirge, and by his illustrations of the mosses of New Guinea, etc. 

 J. Roll enjoyed a close personal friendship with Geheeb for forty years, 

 travelled and collected with him, and exchanged specimens and ideas 

 with him. He has much to say of Geheeb's happy and simple domestic 

 life, and tells of his devotion to music, of his beautiful genial nature, 

 his generosity and unselfishness, and his eagerness to help all around 

 him and especially apothecaries and bryologists. He had friends and 

 correspondents in all lands, and he never made an enemy. In 1897 he 

 moved from Geisa to Freiburg in Breisgau. His herbarium was pur- 

 chased by a friend and presented to the Berlin Botanical Museum.

Chara contraria and C. dissoluta4 — C.P. Sluiter writes an exhaus- 

 tive account of these two species, which have been sometimes united and 

 have always been somewhat puzzling. The author first gives a history 

 of all the views held by former authors on the systematic position of 

 these plants, and then sets herself to answer the following questions : 

 1 . What are the relations between Chara dissoluta A. Br. and C. con- 

 traria A.Br.? 2. Is an uncorticated Chara from Busskirch (submitted 

 to the author for examination) a member of the contraria group, is it 

 identical with C. dissoltda, or is it more nearly related to other uncorti- 

 cated species ? In order to answer these questions the author made a 

 careful and minute study of the external and internal morphology of 

 the two species in question from excellent material, and she gives details 

 of her results, illustrated by text-figures. The same study was made of 

 the Busskirch plant, and the results finally discussed. The similarity 

 between C. contraria and C. dissoluta f. helvetica is so great that the 

 author apparently regards the latter as being a degenerate form of the 

 former, and the Busskirch plant as belonging to the same series of forms. 

 She finds that the uncorticated form of C. dissoluta f. helvetica is quite 

 independent of the form with one row of corticating cells ; but what 

 causes this form she is unable to say, and declines to enter into any
