 510 SHORT NOTES. and Morrison 2 (Salvia pratensis and Carex vesicaria). This gives a total of 725 species known before Ray's time. Then Ray adds no less than 205 new species to the list, making a total of 980. As the list contains altogether 1440 species, we have 510 discovered since Ray's time, that is roughly within the last 200 years. •..i;/. SHOUT NOTES, lio^ ^di d^ERANiuM MOLLE, var. (p. 477). — Mr. Dil^ii'cfuotes G. villosum Tenore for this. Neilreich {Nachtrdge zu Mah/s En. PL Aiist. 282) says that the reference is not correct, but should be G. viUoswu. Reich. Ic. xv. f. 4880 (non Ten.), and that G. villosum Tenore {El. Nap. iv. t. 166) is a synonym of G. pyrenaicmn L. I ask for information ; so many unauthorized names have crept into our Floras, that it is best to sift them at once. Nyman makes a subspecies of G. villosum Ten. undieY pyrenaicum, and puts a ! after Tenore's name (from which it would seem that Neilreich was right) ; and in his Supplement, under G. mollej Jias " G, villosum Reichb. (non Ten.)."— Arthur Bennett."; ^'^ '; '^l'^ '*",^' Hypochceris glabra L. (p. 476). — In Mr. Dunn's interesting note on this plant there are one or two points that I fail to under- stand. He says his var. 7iana has " a sessile pappus in two rows, destitute of woolly hairs"; if .really so, how can it belong to the genus ? I should call the plumose pappus of H. glabra rather silky than woolly. I possess a small form of this from Santon Warren, between Thetford and Brandon, Norfolk, but that has the ordinary plumose pappus. In Yorkshire specimens of the var. erostris, however, the hairs are evidently deciduous, sometimes from above to below, in others from below upwards. Of course we know the shorter outer circle of the hairs of the pappus are not plumose, only denticulated. I do not find in ordinary typical specimens of H. glabra L. that the hairs are not continued from the apex to the base of the pappus (unless from causes of growth) or crown of the fruit. In many dozens of specimens examined in 1886 on Mitcham Common, Surrey, the plumose hairs extended from the apex to base of the pappus. Cosson and Germain [Flore des Environs de Paris, 427, 1845) divide the species as under: — a. vulgaris. Achenes of two sorts, those of the circumference destitute of a beak, those of the centre attenuated into a long beak. p. erostris {— H. arachnoidea Poir. Vict. 5, 572). Achenes all destitute of a beak. y. rostrata {= H. Balbisii Loisl. not. 124). Achenes all attenu- ated into a long beak. This was called by Godron {Fl. Lorraine^ ii. 58, 1843) H. glabra p. Loiseleuriana. Sonder (El. Hamburgh, 429, 1851) gives a "/?. decipiens, achaeniis omnibus rostratis, rostro achsenium aequante, H. Balbisii Koch, non Loisl." I have not seen this. There is also, according to Archangeli, an earlier name for H. Balbisii [Comp. Fl. It. 414, 1882). He calls it y. minima Cyr. = H. miTiiinaCjxillo (PI. Rav. Neap. Fasc. i. 29, t. x. (1788)).
