shoot; the reason of this is unknown to ine. Upon the 

 oldest portion of the shoot-system which has been figured, 

 adventitioiis roots are seen to be rather abundantly devel- 

 oped. 



According to Raunkiær (1907, p. 46) Veronica offici- 

 nalis is an active chamæphyte; the species is nanophyllous, 

 and evergreen (see above). 



In "Field-notes on the Biology of some of the Flowers 

 of the Færoes" (Botany of the Færoes. Vol. III, p. 1065) 

 E. Warming writes concerning Veronica officinalis: "The 

 diameter of the flower is 7 — 8 mm. The corolla is pale-lilac 

 with stripes of a darker colour. Homogamous. The anthers 

 and the stigma occur at the same level, but as the stamens 

 are spreading, insect-pollination appears to be necessary for 

 the setting of fruit." 



Geographical Distribution: Europe, Western-Asia, 

 North-America. 



According to Ostenfeld (1901, p. 57) in the Færoes 

 Veronica officinalis is "Rather common in low-lying regions 

 on hill-slopes and on rocky-ledges; also occurs at high levels 

 and there mostly as f. glabrata Fristedt . . . Fl. beginning of 

 July. Fr. August, but bears fruit sparingly; often fails 

 altogether in the hills." 



The specimen illustrated in Fig, 9 was investigated with 

 respect to its leaf-anatomy. The epidermis of the upper 

 surface (Fig. 10, B) had lateral walls, from straight to slightly 

 undulating, and that of the lower surface (Fig. 10, A), 

 rather strongly undulating lateral walls. Glandular hairs 

 with one-celled stalk and two-celled head occurred abundant- 

 ly on both leaf-surfaces. In Fig. 10, C some epidermal cells 

 are sliown under higher magnifying power; the two smaller 

 and thin-walled ones have borne glandular hairs (the small
