Anatomy (figs. 22a, 22&). — There is no cuticle, but the epi- 

 dermal cells (ep.) are protected by the very numerous hairs (h.Ji.) 

 which are found thickly covering both surfaces, more especiallv 

 the upper, which is most exposed. These hairs are unicellular 

 outgrowths of the epidermal cells. The upper epidermis (ep.) 

 consists of regular rather thick- walled cells with no stomata ; 

 in the lower epidermis (l.ep.) the cells are smaller, thin-walled, 

 and interrupted by very numerous stomata (st.). The chloren- 

 chyma (chlor.) forms a regular palisade tissue (pal.), three cells 

 in thickness, densely filled with chlorophyll. The spongy tissue 

 (sp.) occupies the greater thickness of the leaf, and is composed 

 of irregularly shaped cells, very loosely arranged, and so leaving 

 numerous air-spaces. The vascular bundles (v.b.) are surrounded 

 by the endodermis (endo.), and further by a colourless paren- 

 chyma sheath. 



Veronica benthami, Hook. f. 



" Leaves crowded towards ends of branches, sessile, \ in. 

 to \\ in. long, linear or obovate-oblong, obtuse, margin with 

 a few deep serratures and edged with down, very coriaceous, 

 flat, veinless ; opposite pairs connate at the very base. "J 



" Leaves are thick, rather soft, narrow obovate-oblong 

 in shape, dark-green ; with regard to the light, the surfaces 

 of the lower and larger leaves are horizontal and frequently 

 arch downwards somewhat. The structure is that of a typical 

 dorsi- ventral leaf. Nearer the apex of the shoot the leaves are 

 smaller than those below, broader in proportion to their length, 

 and loosely imbricating. "§ 



Hah. — " Small dwarf plant with deep glossy green foliage ; 

 near the sea."|| 



This plant is confined to the Auckland and Campbell Islands. 

 On Campbell Island it is found growing through bushes of Co- 

 prosma or amongst the tussock, with its " rather straggling 

 naked stems marked with many leaf-scars, but quite green 

 above. "§ It appears again in the subalpine rock formation, in
