Lepidium Smithii Hook. — The typical form of Lepidium Srnithii 

 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 

 papillffi, 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 Vaillantii DC. Plentiful in allotments, 

 Long Lawford. — Galeopsis Tetrahit L. var. bifida (Boenn.) Heaths by 

 the " Straight Mile," Dunchurch. — Exiphorbia exigua L. var. retusa 

 DC. Not infrequent as an extreme form with the type. — E. Lathyris 

 L. as a weed at Grandborough and Kenilworth. — Camelina sativa 

 Crantz, TrifoUum agrarium L., and Crepis taraxacifolia Thuill., only 

 recorded from single waste-ground localities, appear in fallows about 

 Rugby. — Alchemilla vulgaris L. \Sir. filicaulis (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, Frod. Fl.

 forms, the commoner one having internal calyx-teeth longer than
