510 SHORT NOTES. 



and Morrison 2 (Salvia j^ratensis and Carex vesicaria). This gives a 

 total of 725 species known before Eay's time. Then Kay adds no 

 less than 205 new species to the list, making a total of 930. As 

 the list contains altogether 1440 species, we have 510 discovered 

 since Eay's time, that is roughly within the last 200 years. 



SHORT NOTES. 



Geranium molle, var. (p. 477). — Mr. Dunn quotes G. villosum 

 Tenore for this. Neilreich [Nachtriuje zii Mahfs En. PL Aust. 282) 

 says that the reference is not correct, but should be G. villosuiii 

 Keich. Ic. xv. f. 4880 (non Ten.), and that G. villosum Tenore {El. 

 Nap. iv. t. 166) is a synonym of G. pyrenaicum 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. under pyre^iaictim, and puts a ! after 

 Tenore's name (from which it would seem that Neilreich was right); 

 and in his Supplement, under G. molle, has " G. villosum Reichb. 

 (non Ten.)." — Arthur Bennett. 



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. nana 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. fjlabra 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 [Elore 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. 



f3. erostris (= H. arachnoidca Poir. Diet. 5, 572). Achenes all 

 destitute of a beak. 



y. rostrata (= H. Balhisii Loisl. not. 124). Achenes all attenu- 

 ated into a long beak. This was called by Godron {El. Lorraine, 

 ii. 58, 1843) H. glabra jS. Loiseleuriana. Sonder {El. Hamburgh, 

 429, 1851) gives a '*/?. decipiens, acha?niis omnibus rostratis, rostro 

 achsenium fequante, EL. Balbisii Koch, non Loisl." I have not seen 

 this. There is also, according to Archangeli, an earlier name for 

 H. Balbisii [Comp. El. It. 414, 1882). He calls it y. minima Cyr. 

 = H. minima Cyrillo {PI. Eav. Neap. Fasc. i. 29, t. x. (1788) ). 

 Nyman, I see, says, " H. minima Balb., non Cyr." I possess
