Achillea
Upwards of 100 species have been described by botanists (but, according to the authors of the "Genera Plantarum," the number may be considerably reduced): they inhabit Europe and Western Asia. Leaves alternate. To the species described on pp. 11-12, Vol. I., the following should now be added:
A. rupestris (rock-loving).* fl.-heads white, greenish towards the centre, pedicellate, 1/2in. to 3/4in. broad; corymbs 1in. to 1 1/2in. in diameter. May. l. on the shoots rosulate, 1/4in. to 1/2in. long, linear-spathulate, entire; cauline ones similar, scattered, spreading. Rootstock tufted. Southern Italy, 1886. (B. M. 6905.)
