26 NOTICES OF BOOKS AND MEMOIRS. 



lu the ' Bulletin de la Federation des Societes d'Horticulture 

 de Belgique ' for the year 1877, recently published, there will be 

 found a catalogue of the flora of the ^Drovince of Liege by 

 T. Durand. The district is divided into the six regions, previously 

 pointed out by M. Crepin, and localities are given for the rarer 

 species. The list has evidently been compiled with great care, 

 and no plant admitted without good claims ; even after the 

 rejection of no less than 211 sj)ecies which have been recorded on 

 insufficient grounds, the flora of this rich botanical district com- 

 prises 1202 species, 297 races or sub-species, and 117 marked 

 varieties, a remarkably large number. 



' Cien Helechos de Filipinas,' by Don Maximo Luguna, is a 

 catalogue of the Ferns of the Philippines, arranged according to 

 Hooker and Baker's ' Synopsis Filicum,' 1874, and includes 102 

 species. The paper was published in the ' Anal, de la Soc. Esp. 

 de Hist. Nat.', vol. vii., 1878. 



From the same author we have also received a descriptive 

 clavis of the Conifers and J me7itifera) of Spain, with the local names 

 of the trees in different provinces, list of localities, &c. 



The first part of the ' American Quarterly Microscopical 

 Journal ' gives promise of a valuable addition to the periodicals 

 of its class. It is edited by G. E. Hitchcock, and contains also 

 the * Transactions ' of the New York Micro scoj^ical Society. In 

 Botany the number contains a ' Description of new sj)ecies of 

 Diatoms,' by H. L. Smith, with a fine plate, and ' Observations on 

 several forms of Saprolcgnm,' by F. B. Hine, which is illustrated 

 by four plates, and is to be concluded in the next number. 



The Report for 1877 of the Botanical Section of the Yorkshii-e 

 Naturalists' Union is printed in the part of the ' Transactions ' 

 lately issued, having been read and adopted at the first annual 

 meeting, held at Wakefield on October 6th, 1877. It is well and 

 carefully drawn up, and contains a list of eighteen species found 

 in the vice-county, " South-west Yorkshire," but not included in 

 ' Topographical Botany.' 



It is a good thing that our large schools should show an 

 interest in natural science, but it is to be regretted that too great a 

 hurry to rush into print should have led the Dulwich School 

 Science Society to publish such a Botanical Report for 1878 as 

 appears in its first annual volume. This consists of a * Flora 

 Dulwichionsis,' di'awn up by two members of the School Society. 

 No information beyond this, that the district extends from Dulwich 

 to Boxhill is given, but a large number of the species enumerated 

 could never have been seen, unless in gardens, in that space. 

 RanunciduH '' (/raminea,'' Sediwi aiiglicum, Spiranthes cestivalis, 

 Cladium Mariscus, Adiantum Capilhis-veneris and Carex arenana 

 are examples of such erroneous or misleading entries. We have 

 had good school floras, but Dulwich must work on a very different 

 plan to the present to effect any such useful result.
