The Scottish Naturalist. 283 



Under the var. trigranulatus of Rumex crispus, we are rather inclined to 

 think that the locality " Annan " is a misprint ior ' ' Arran." 



Populus alba is stated to be cultivated as far north as Forfar, but " does not 

 flower in Scotland?" Scottish botanists should make observations on this 

 point, and prove or disprove it. 



In the Orchidacetz several changes in the arrangement and nomenclature 

 have been made. For example, Gymnadenia and Neotinea (or rather Tinea) 

 become sections of Babenaria, which also includes Leucorchis (H. albia'a), 

 Caloglossum (ZZ viriais), and Platanthera {H. bi folia and H. chloranlha). 



In Juncus, J. tenuis (from Hereford) is added ; while under J. supinus 

 some changes have been made, the var. Kochii Bab. having been omitted with- 

 out any explanation. What seems to be it we have found in several localities 

 in Scotland. 



Luzula also has undergone some changes in the nomenclature ; fcr example,. 

 Z. maxima instead of Z. sylvatica ; Z. vernalis instead of Z. pilosa ; while 

 Swartz is given as the author of Z. arcuata instead of Hooker. We notice 

 also that L. erecta replaces Z. multiflora, but the plant is still left as a var. of 

 Z. campestris, contrary to the opinion of many other writer-. 



Alisma nutans is removed to the genus E/isma, and Triglochin and Scheu- 

 chzeria to the order Aaiadacece. The genus Potamogeton has been revised by 

 Mr. Arthur Bennett, and several additions and changes made in it. Thus 

 P. polygonifolius, P. plantagineus, and P. lonchites have been raised to the 

 rank of species, while P. Kirkh is considered to be probably a form of P. 

 polygonifolius. P. Zizii is described as a sub-species (of P. linens), and P. 

 decipiens is raised to the rank of sub-species (o! lucens). J . Grijjiihii, A. 

 Bennett, is a new species allied to P. pm/ongzts, and the true /. salicifolius 

 Wolfg. is admitted as a British species. P. compressus, being a doubtful 

 name, is suppressed in favour of P. zosterif alius, both which and P. acutifolius 

 Fink, are considered to be full species. Under P. pusillus three sub-species 

 are admitted-—/', pusillus proper, P. Friesii Rupr., and P. Stttrrockii A. 

 Benn. The latter is said to occur in Forfar and Perth, but we think that it 

 has been found in Perthshire only. Finally, P. filiformis Nolte is accorded 

 full specific rank. In Naias the recently discovered (in Britain) N. marina is 

 described, but N. graminea Delile is not even mentioned. 



In the arrangement of Cyperacca: some important alterations have been made. 

 Hdeccharis (formerly Eleocharis) is restricted to three species, and //. uni- 

 glumis is considered to be a sub-species. Scitpus include^,, in addition to the 

 species formerly contained in it, those which in the last edition were placed in 

 Eleocharis (in part), Isolepis, and Blysmns. 



In Carex it may be noted that the author and Mr. Baker " do not doubt " 



that C. fulva Good, is the plant figured by Goodenou^h, and that the name 



fulva must be retained in preference to Honiscliuchiana, which is adopted by 



some other authors. C. Grakami is considered to be a sub-species, instead of as 



formerly a variety, of vesica} ia. 



Amongst the grasses also many alterations will be found. Thus Alopccurus 

 fnlvus and bidbosus are reduced to sub-species of geniculatus ; several sub- 

 genera have been accorded full generic rank ; and to Festuca two species have 

 been added — F. rigida and F. loliacea, which were formerly in Glyceria. 

 The name Agropyrum replaces the familiar Triticum. 



Amongst the ferns we find JVoodsia ilvensis reduced to the rank of a sub- 

 species. Equisetum pratense 'is said to grow in marshes (as is also E, hyemalc). 

 This statement requires correction, as though E. pratense usually grows near 

 streams, it is always, so far as we have seen, in well-drained and, on the 

 whole, rather dry places. With E. hyemale our experience is not so extensive, 

 1 tut we have not seen it in marshes. Lycopodium alpinxim is reduced to the rank 

 of a sub-species of Z. complanatum, which is admitted as a British species, 

 and which should be looked for in Scotland. 



Before concluding this necessarily too brief a notice of a work so full of 

 interest to the botanist, we must allude to the use of the word "Isla" 

 instead of " Islay " as the name of the island on the West of Scotland where 

 so many plants seem to find their northern boundary. Doubtless the author
