The text-figures are numerous and a great many of them have 

 been drawn by the author himself. 



The book is written in Danish and consequentty to be used 

 only in the Scandinavian countries, but no doubt translations into 

 other languages will appear. C. H. Ostenfeld. 



Adamson, R. S., Comparative Anatomy of the Leaves of 

 certain species of Veronica. (Linn. Soc. Journ.-Botany, XL. 

 p. 247—274. 17 figs. 1912.) 

 Thirty-nine species of shrubby type and natives of New Zea- 



land are dealt with. For purposes of description, five groups are 



recognised, (the spp. given as examples are those illustrated amongst 



the figures): 



A, large or elongated leaves without distinct xerophilous eha- 

 racters, a constant feature is that the central bündle ends in a 

 hydathode: V. salicifolia, Forst., V. elliptica, Forst., etc.; lowland 

 species below 600 metres. 



B, leaves like A, but thick and much more xerophilous, epi- 

 dermis thickened and cuticularized, central bündle ends in a hyda- 

 thode: V. ignota Hort. Edin., etc.; mountainous regions. 



C, leaves small. elliptic-lanceolate and concave (spoon-shaped), 

 leathery, and somewhat xerophilous: V. Traversii; upland and sub- 

 alpine. 



D, leaves like C, but thicker, usually glaucous, mesophyll rarely 

 differentiated, without bundle-hj^dathodes, stomata on both surfaces: 

 V. pinguifolia, Hook, f., V. Colensoi, Hook, f., V. glaucophylla, Cock., 

 V. carnosula, Hook, f., V. monlicola, Armstr. ; alpine and subalpine, 

 600—1600 m. 



E, leaves much reduced: V. Hectori, V. lycopodioides, V. cupres- 

 soides; alpine. 



Groups A — E show increasing xerophily. 



F, leaves toothed and petiolate, bundles end in hydathodes: 

 V. catarractae, Forst.; lowland. 



Certain general anatomical characteristics are pointed out: 

 lateral walls of epidermal cells, hairs, existence of tannin-sacs, the 

 stomatal group of cells, hydathodes (not in all), features of the leaf- 

 base especially the presence of a corky tissue long before leaf-fall. 

 The general conclusions deal with distribution in relation to xero- 

 philous characters, and the comparison of the floristic Classification 

 with that based on leaf-structure. W. G. Smith.
