a scale to be of much use; its redeeming- feature is that it shows 

 the areas where glacial or alluvial deposits are present. To call 

 this a map of 'Geology ;md Flora' is ambitious. There are 

 now in the market several excellent road-maps, clearly printed 

 and with altitude shading or colouring ; it will be necessary to 

 use a map of this kind before one can Hnd the localities men- 

 tioned in the Flora, or fully realise the author's reasons for 

 selecting the botanical areas. The short account of the physio- 

 graphy of the East Riding only whets the appetite for more, 

 and it contains the embryo (which we trust will come to 

 maturity) of an account of the evolution of plant-life on land 

 reclaimed from the Humber estuary. The topographical sum- 

 mary and the few pages on the distribution of East Riding 

 plants reveal how interesting the Riding really is, and how 

 much could have been made of it. The summaries of East 

 Riding plants (pp. 41-46) need not have been so numerically 

 carried out. With the exception of that of genera, etc., it is quite 

 probable that another botanist would come to different results. 

 The attempt to arrange the species into habitats is an unfor- 

 tunate medley. Hygrophiles and xerophiles are habitat groups 

 generally admitted ; maritime and estuarine would probably 

 have fitted in better as subdivions of halophytic plants ; the 

 large number (one-third of the total) of ' ordinary (growing on 

 drv land generally) ' is an admission of weakness ; while to 

 designate denizens, colonists, aliens, and incognita as habitats 

 is not in strict accordance with the meaning of the word. 

 A little guidance from 'North Yorkshire,' or the now standard 

 text-book of Warming would have prevented this. The local 

 names of plants are few for an agricultural county, e.g., 

 Spergula arvensis, Plantaoo major, and many others seem to 

 have escaped local baptism. 'Blood Geranium Cranesbill ' has 

 a better-known, though less elegant, name, while ' rough rigid 

 Trefoil ' is certainly stifl. 



The list of Mosses is by another pen, and it is well that it 

 forms but an appendix. The list looks short, but this is 

 explained when one finds that nearly 60 species and varieties 

 recorded in The Natiinilisf for the East Riding since 1898 have 

 been omitted, to say nothing of a larger number of locality 

 records. On pages 237, 239, and 243 names occur without 

 localities, and on pages 239 and 242 the same species are repeated 

 under different names, while Tortida montana and PliyscomitrelUi 

 patens, marked as new East Riding records, were recorded by 

 Mr. Marshall himself in this journal in 1898, p. 240.
