180 THE JOUBNAL OF BOTANY 



S. perennis, have no adventitious .roots. The three flowers of the 

 cyme are roughly equal in size ; and the central one reaches two- 

 thirds of the way up the segment. The seed is nearly like that 

 of S. iJerennis, but its hairs are shorter.

In the salt-marshes (both maritime and inland) of Europe and 

 the Mediterranean region this species is very abundant, and often 

 social. Two forms, connected by intermediates (not hybrids), are 

 distinguishable : — 



S. EUEOPiEA forma stricta, form. nov. {S. acetaria Pall., 

 S. stricta Dum., S. Emerici Duv.-J.). Eouy (Fl. de Fr. xii. p. 59, 

 1910) uses the name "S. biennis Afz." for this form, which he 

 designates a " race " ; but a reference to Smith's Flo. Brit. i. 2 

 (180()), cited by Rouy, shows it to be a mere MS. name, and one 

 founded on a serious misconception. This form is usually a much 

 branched and vigorous plant, with the branches fastigiate, and 

 with the terminal spikes usually very long. It is the south 

 European form of the species, and spreads northwards at least 

 to Brittany, Belgium, and Essex. 



S. EUEOP^A forma patula, form. nov. {S.'europcea Linn, et 

 S. herbacea Linn, in sensu stricto, S. anuria Sm., S. ptyocumbens 

 Sm., S.p)atula Duv.-J. pro parte, S. herbaceava,r. jyatula Buchenau, 

 Fl. Nordwestd. 192, 1894). This form has the branches spreading, 

 that is, forming wide angles with the stem, and is usually a less 

 branched plant than the preceding form. As a rule, its flowering- 

 spikes are shorter. Being less vigorous than the preceding form, 

 it frequently gets toppled over by the tides, and is then frequently 

 misnamed S. procumbens. It is pre-eminently the north European 

 form of the species. By Rouy {op. cit.) it is regarded as a "race"; 

 but (according to his wont) he gives it a binomial — S. atimia — as 

 if it were a species. It is the prevailing form in Scotland. The
