ft. V. Riviniana (Reich.), with the intimation that they are probably 

 distinct species. Moehringia trinervis has been transferred to the 

 genus Arenaria ; Arenaria leptoclados (Guss.) takes its place as a 

 species. The name Hypericum anglicum (Bert.) is still preferred to 

 H. datum (Ait.) ; but the plant is enclosed in brackets, as having 

 very slender claims to be accounted British. Ulex strictus (Mackay) 

 is reduced to a variety of U. europceus (Linn.). Lotus tenuis (Smith), 

 which appeared as a species in the 'Flora of Cambridgeshire,' is 

 once more joined to Lotus corniculatus (L.). Lathyrus tuberosus (L.) 

 is added, with the brand of a possibly foreign origin. The genus 

 Rubies has been thoroughly revised, and the number of species raised 

 from forty to forty-five. Dryas depressa (Bab.) is reduced to a 

 variety of D. octopetala (L.). Lepigonum now includes four species 

 by the addition of L. rupestre (Kindb.) and L. neglectum (Kindb.). 

 Sedum purpureum (Tausch) is now called S. Fabaria (Koch). Ga- 

 lium parisiense (L.) changes to G. anglicum (Huds.). Galium elon- 

 gatum (Presl) is now included under G. palustre (L.). Centaurea 

 nigrescens of former editions is reduced to a variety of C. nigra, under 

 the name of G. decipiens (Thuill.). Centaurea paniculat a (L.) adds 

 another plant to those peculiar to the Channel Isles. Two Hieracia 

 have changed name : H. cerinthdides is now called H. anglicum 

 (Fries), and H. stelligerum becomes H. fioccosum (Backh.). Cicendia 

 Candollei (Griseb.) is now C. pusilla (Griseb.). Lycium barbarum 

 (L.) and Veronica per egrina (L.) are added to the list of naturalized 

 plants. Ajuga alpina is removed, with the remark that the plant 

 figured in ' English Botany' seems to be a slight variety of A. reptans 

 (L.). Polygonum laxum of former editions becomes P. nodosum 

 (Pers.). Callitriche peduncidata (DC.) changes to C. humulata 

 (Kiitz.) ; C. stagnalis (Scop.) is allowed as British, but only in the 

 form of a variety. Parietaria erecta of former editions is now con- 

 sidered a form of P. diffusa, the true P. erecta of Koch not having 

 occurred in Britain. Gladiolus illyricus (Koch) is added, and ap- 

 pears as a true native of Hampshire. Luzula Borreri (Bromf.) is 

 just noticed, as an abortive state of L. pilosa (L.). The plant men- 

 tioned as Potamogeton gracilis (Fries) is now referred to P. pusillus 

 (L.) ; P. sparganiifolius (Laest.) takes its place as certainly iden- 

 tical with Fries' s plant from Lapland. Car ex ericetorum is new. 

 Poa polynoda (Parnell) is united to P. compressa (L.). Festuca 

 ambigua(he Gall) is admitted. Triticum pungens (Pers.) is another 

 addition to the Grasses. Triticum laxum (Fries) is changed to T. 

 acutum (DC). 



Equisetum Telmateia (Ehr.) becomes E. maximum (Lam.). Alio- 

 sorus crispus (Bernh.) is now called Cryptogramme crispa (R. Br.). 

 Woodsia hyperborea (R. Br.) takes rank as a species distinct from 

 W. ilvensis (R. Br.). The genus Pseudathyrium (Newm.) is now 

 merged in Polypodium. Lastrcea remota (Moore) is admitted as a 

 variety of L. spinidosa (Presl). Athyrium fontanum is now placed 

 in the genus Asplenium. Asplenium acutum (Bory) is reduced to a 

 variety of Asplenium Adiantum-nigrutn (L.). Isoetes echinospora 

 (Dur.) is new; Isoetes Hystrix (Dur.) is also new.
