by him to Sarasin & Roux's Nova Caledonia. ^ The list enumerates 42 species 

 with notes upon the localities and general distribution. Macromitrium Sarasini 

 Ther. and Isopterygium Sarasini Ther. are described as new species, with three 

 other new varieties or forms. 



Two recent issues of the Recueil des Publications de la Societe havraise 

 d 'etudes diverses contain bryological articles by M. Theriot. The first^ on the 

 Mosses of Annam discusses a small collection of 28 species made by Mr. A. 

 Krempf. Three of the species collected are new to the Asiatic mainland, the 

 whole collection showing strong affinities with the flora of the Sunda Islands. 

 The new species are: Leucoloma Krempfii Ther., L. annamense Ther., Leucobryum 

 Krempfii Ther., Neckeropsis Krempfii Ther., Homaliodendron crassinervium 

 Ther., Pinnaiella (?) corrugata Card. & Ther. and Ectropothecium annamense 

 Ther., all of which are illustrated in the two plates. Two new varieties are 

 also proposed in Neckeropsis and Vesicularia. M. Theriot raises the question 

 of the propriety of separating the two genera Neckeropsis and Himantocladium 

 from Neckera, since Neckera fiagellifera Broth, belongs to the one genus accord- 

 ing to its fruiting characters and to the other in its vegetative aspect; indeed, 

 Brotherus and Fleischer respectively classify it one in one genus, one in the 

 other. The author also concludes that Pterohryopsis subacuminafa Broth. & 

 Par. is far more closely related to Pt. Wi^htii (Mitt.) Broth, than to Pt. acuminata 

 (Hook.) Fleisch. 



The second article* is upon the mosses of Madagascar, 6 sphagna, 60 mosses, 

 and 8 hepatics being listed, the last by name only. The new species proposed 

 are the following: Funaria delicatula Ther., Brachymenium argenteum Ther., 

 Br yum Perrieri Ther., Philontis Perrieri Ther., Rhacopilum Perrieri Ther., all 

 save the last being figured. There are brief notes upon Trematodon platybasis 

 C. M., Macromitrium adelphinum Card., and Amblystegium riparium (L.) Bry, 

 Eur., a species not hitherto reported from Madagascar or from Africa south 

 of the Mediterranean region. The description of Leucoloma albocinctum R. & 

 C. is supplemented by a description of the fruit, and there are more extended 

 notes upon Nanomitropsis laxifolia (R. & C.) Card, (whose generic affiliations 

 seem doubtful), Brachymenium capitulatum Card, and B. radiale C. M., a syn- 

 oicous variety of Philonotis imbricatula, and the forms or varieties of Polytrichum 

 subformosum Besch. M. Theriot also states that after a study of the type ma- 

 terial of Leucomium mahorense Besch. he is convinced that it is identical with 

 L. debile (Sull.) Mitt., and that judging from the published plate SuUivant erred 

 in describing his species as "dioicus," the plants being figured as autoicous.
