 The leaves in this species are usually tripartite, but they are occa- 

 sionally simple (the var. Integra., Koch, in Linnaea, xvii. (1843) 44), 

 but probably it is only a state, not a true variety. The stem is 

 sometimes very rough (the /. rugosa) ; the var. minor, Wimm. et Grab. 

 Fl. Siles. ii. 218, is an analogous form to the var. minima of S. cernua. 

 I have seen it at Holyport, &c. 



B. tripartita occurs in all the bordering counties.

 Mus. 1800. A. millefolium, Dr. Noehden, Mavor's Agr. Berks, 1809. 



The Yarrow is one of our commonest species, and exists under 

 several modifications, the most marked of which is a densely pubes- 

 cent form, the var. lanata, Koch, Syn. Fl. Germ. 373 (1837), which 

 occurs near Bracknell, Snelsmore, &c. The form with deep red flowers 

 I have seen in the meadows near Sonning and Pangbourn, near 

 Eadley, and at Marcham, but these forms appear to merge gradually 

 into the type. 



A. Millefolium occurs in all the bordering counties.
