 SHORT NOTES. 477 appear as below. The names under each division are not in all cases synonymous. 1. Achenes all truncate, (a) Pappus woolly below. H. arach- noidea DO. ; H. contexta a. homceosperma Wallr. (6) Pappus not woolly. H. glabra L. var. nana. 2. Outer achenes alone truncate, (a) Pappus of truncate achenes woolly below. H. arachnoides Poir. ; H. adscendens Brot. ; H. inter- texta Peterm. ; H. minima Desf. ; H» ascendens Walp. [H. hispida Roth (non Brot.), in which only a few central achenes are rostrate, connects this with 1 a.] (b) Pappus not woolly below. H. glabra L. (as restricted by Poiret, VVallroth, and Petermann) ; H, dimorpha Brot. (non Sang, nee Ten. nee Salz.). 8. Achenes all rostrate. H. Balbisii Maur. ; H. Loiseleuriana Godr. The common English form has webbed pappi, and comes under 2 a.— S. T. Dunn. Lepidium Smithii Hook. — The typical form of Lepidium Smithii Hook., as described by Smith {Eng. FL), has ** Pouches . . . entirely destitute of the minute concave scales so characteristic of Lepidium campestre Br." The species is common in Devonshire, but in all the specimens examined the pouches are more or less rough with papillae, usually smaller, but often not less numerous than those of L. campestre. A complete series could be made from quite smooth- pouched plants to the other extreme, but it is a remarkable fact that, though the latter is more frequent in Britain and the Continent (to judge from the material in the British Museum Herbarium), and is the prevalent if not the only form in some districts, the former is made the type by Smith. It is convenient to have names for extreme forms, especially when permanent over large areas, and I propose to call the rough-pouched form L. Smithii Hook. var. papillosum. — S. T. Dunn. WARwicKsmRE Plants. — The following are not included in Bagnall's Flora : — Galium Yaillantii DO. Plentiful in allotments. Long Lawford. — Galeopsis Tetrahit L. var. bifida (Boenn.) Heaths by the " Straight Mile," Dunchurch. — Euphorbia exigua L. var. retusa DO. Not infrequent as an extreme form with the type. — E. Lathy ris L. as a weed at Grandborough and Kenilworth. — Camelina sativa Crantz, Trifolium agrarium L., and Crepis taraxacifolia Thuill., only recorded from single waste-ground localities, appear in fallows about Rugby. — Alchemilla vulgaris L. war. Jilicaulis (Buser), noted for this county by Linton {Journ. Bot. 1895), occurs well marked in meadows near Francton Wood. — Polygala oxyptera Reichb. Heath near Dun- church ; extends northern range in the county. — S. T. Dunn. Geranium molle. — The form of Geranium molle L. with petals twice the length of the sepals certainly occurs in England, and is not uncommon on the greensand in Surrey. This is G. villosum Ten., reduced to a var. of G. molle in Willkomm & Lange, Prod. FL Hisp. and Gren. & Godr. FL Fr. = G. molle jj. grandijlorum Vis. FL Dalm.—S. T. Dunn. Peplis Portula. — This plant occurs on the Continent in two forms, the commoner one having internal calyx-teeth longer than
