having a limited flowering- time. The other plants noticed are in 

 flower with us at almost any period and include Caj)sella Bursa- 

 pastoris, Gardamine hirsufa, G.Jiexuosa, Stellaria media (only with 

 three or Ave stamens, the ten-stemmed S. ner/lecta is more limited in 

 its flowering-period with us), Cerastium violgatum, Taraxacum offi- 

 cinale^ Bellis iierennis, Senecio vulgaris^ Lamium purpureum^ 

 Linaria Cymbalaria, and Poa annua. 



The spring flowers include Ranunculus Ficaria, Viola odoraia, 

 Potentilla sterilis, Fefasites fragrans (apparently quite a wild plant 

 in Somerset), Daphne Laureola, Mercurialis perennis, and Corglus 

 Avellana. The Primrose must also be included here, though stragglers 

 are often found flowering in secluded dells right through the winter 

 months. A locality for the Snowdrop was visited, but no flov/ers 

 were seen. 



The stragglers, or third group, include the following : — Ranunculus 

 Flammula., R. repens, Sisymbrium officinale, S. Tlialianum, Lychnis 

 dioica, Sfellaria Holostea, S. graminea (the former is not uncommon 

 during mild winters, but the latter Avas a surprising find), Arenaria 

 serpyllifoUa, Sagina procumhens, Reseda Luteola, Geranium Ro- 

 bertianum, G. columhinum, 3Ialva sylvestris. several Ruhi, Geuni 

 tirbanum, Spircea Ulmaria, Fragaria vesca, Vicia sepium, Hedera 

 Helix, Chcerophyllum temulum, Anthriscus sylvestris (probably 

 better placed in the second group), Senecio Jacobcea, S. erucifoliusy 

 S. sylvaticus, S. squalidus (naturalized in Taunton and in flower 

 from the end of April), S. aqaaticus, Chrysanthemum Farthenium, 

 Achillea Millefolium, Crepis capillaris, Leontodon autumnale, 

 Lapsana communis, Ficris hieracioides, Matricaria Chamomilla, 

 Sonchus oleraceus, S. asper, Veronica persica {Fuxbaumii^, V. ar- 

 vensis, V. Qhamcedrys, V. didy ma, Lamium album, Frunella vulgaris, 

 Chenopodium album, Rumex conglomeratus, Euphorbia Feplus, 

 E. exigua, and Factylis glomerata. — W. Watsois". 



PoTAMOGETON ACUTiFOLius Link. On p. 17 I gave the northern 

 limit of this species as 60^ 12' N. lat., from Hagstrom's book. On 

 checking these limits I find I have a specimen named as F. zos- 

 terifolius Schum., from Finland — " Karelia Onogensis. Schunga. 

 Aug. 1888. A. 0. Kihlman." This is 62° 30' N. lat. In Hjelt's- 

 Consp. Fl. Fenn. 3, p. 540 (in Act. Soc. Fauna et Flora Fenn. v. 

 1895) P. zosterifolius is recorded from Schunga by Norrlin : this- 

 is two degrees farther north, and records the species from Finland. 



Aethue BE:y?^ETT. 



New Yaeiett of Nitella elexilis. In 1884 a Nitella was 

 discovered in Cambridgeshire by the late Alfred Fr^'^er, which, though 

 monoecious, much resembled N. opaca in its dense fruiting heads, its 

 large antheridia, and the more or less mucronate ti2:)s to the secondary 

 branchlet rays. It was so markedly protandrous in character that 

 when first collected, early in May, it had the appearance of being the 

 male plant of a dioecious species. It was originally observed in the 

 Old Bedford River at Sutton Gault, but was subsequently found to> 

 occur in a number of stations in the adjacent fenlands of Cambridge-
