Dixon, H. N„ Miscellanea Bryologica. I. (Journ. of Bot. LI. 

 608. p. 244—247. August 1913.) 



The author shows that the rare New Zealand moss, Tetra- 

 phidopsis novae seelandiae Broth. & Dixon is identical with the older 

 plant Meteoriunt pusillum Hook. f. et Wils. And he describes the 

 male inflorescence of the species. Another New Zealand moss, 

 Ditrichwn byachycarpurn Hpe., has a confused synonymy, which 

 the author makes clear. The third moss discussed is Weisia Wel- 

 wüschii Schimp., which has been reduced as a synonym of Campy- 

 lostelium strictum Solms by Limpricht and others. That is an 

 error. The two species are perfectly distinct in Ihe structure of 

 leaves, theca and peristome; and the latter is silicicolous, the for- 

 mer calcicolous. A. Gepp. 



Dixon, H. N., Miscellanea Bryologica. II. (Journ. of Bot. LI. 

 611. p. 324—330. November 1913.) 



The author gives the history of Ditrichuni ßexifoliutn (Hook.), 

 and reveals a number of species irom Africa, India, Austral- 

 asia and South America, which are mere S5monyms of it, and 

 must be reduced. He also publishes critical notes on some half 

 dozen species of Thuidiuin frora Australasia and Oceania, ad- 

 ding a diagnosis of T. Orientale Mitt. sp. nov. from Penang. Finally 

 he records Astomum Levieri as occurring in N. Africa.

Dixon, H. N., Studies in the Bryolo gy o f New Zealand , 

 with special reference to the herbarium of Robert 

 Brown, of C hristchurch , New Zealand. (New Zealand Inst. 

 Bull. NO. 3. 29 pp. 4 pl. Wellington, N. Z. 30th June 1913.) 



The author points out the exceeding difificulty which besets the 

 study of the mosses of New Zealand. This is due to the creation 

 of a multitude of new species by C. Müller, W. C ölen so, and 

 Robert Brown. Of most of these new species it is impossible to 

 obtain authentic specimens; and the majority of them have not 

 been figured at all, or quite inadequately. R. Brown's descriptions 

 are brief and insufficient, and his type-specimens have been destroyed 

 for the most part. The present series of papers is intended to bring 

 together, so tar as is possible, the species hitherto recorded for 

 New Zealand. The first paper is a revision of Z)/cr««o/omör^ with a 

 key to the 16 species. Descriptions of the following new species 

 are given: D. platycaulon (Q,. M.), D. grossialare (C. M.), D. chryso- 

 drepaneurn (C. M), D. cylindropyxis (C. M.), D. plurisetuni (C. M.). 

 All the species are figured; and füll synonymy and critical notes 

 are supplied. A. Gepp.

 (Rhodora. XV. p. 21-28. February 1913.) 



A complete list, embodying the corrections and additions of the 

 past 10 3"ears, of the species of Ricciaceae, Marchaiitiaceae, Metsge- 

 riaceae, Jungermaniiiaceae, and Anthocerotaceae known to occur in 

 the six New England states. These number 177 species, as against 

 123 species in the list of 1903, a gain of 54 species or nearly 44 

 per Cent. Those records which are additions to the flora are listed 

 separately, as well as others which are reductions to synonym}^ or 

 other changes of names. Maxon.
