only two linnean species: Antit'rhtnwn salatile and Thymus Zygis. 

 In both cases the names are assigned to plaats on the authoritj of 

 the Linnean herbarium, which from the synonymy and country ci- 

 ted could not have been intended by Linnaeus». 



I will bere raention in illustration of the foregoing some cases 

 in which I cannot approvo of takiog up the oldest names. 



«C. caulibus subflexilibus subopacis funicularibus, verticillis di- 

 stantibus, ramulis linearibus apice obtuso-acuminatis. Pianta desiccata 

 glaucesceus». Such is the originai descriptioa of Chara obtusa Desv. 

 ined. (in LoisCLEUR, Notice sur les Plantes ajouter à la Flore de 

 Franco (Flora gallica), Paris 1810, p. 136-7). That this concernes 

 C/i. stelligera Bauer (1829), A. Braun et Auct. recent, is not easy 

 to understand because the descriptioa is equally applicable to seve- 

 ral species of Nitella and Tolijpella and young states of Charce 

 (even of species known before 1810). On the other band Ch. ulvoi- 

 des is too well described and figured ') to be mistaken. The species 

 therefore ought to be named Tolypellopsis ulvoides and Chara stel- 

 ligera regarded as a variety of it. 



Conferva arborutn was described by Agardh in Systema Algar. 

 (1824) p. 88 as follows: «fìlis simplicibus tenuibus intricatis artica- 

 lis diametro duplo longioribus. Ad corticem Arborum in insulis Maria- 

 nis, ubi lectam signo «Confervse CC.» «comraunicavit Gaudichaud». 

 (The genus Conferva is included by Agardh 1. e. p. XXV in «Con- 

 fervse genuinse» which are «viridescentes»). I agree with Hariot's 

 statement with reference to this in bis «Notes sur le genre Tren- 

 tepohlia Mart. » in Journ. d. Botanique 1889-90, pag. 383 (reprint 

 p. 30). « La brièveté de la description ne révélant aucune particula- 

 rité n'était pas faite pour donner une idée sufflsante de cette piante, 

 qui est restée à peu près inconnue jusqu'à ce jour». I would bere 

 remark that Agardh, 1. e. p. XXI, established a genus Chroolepus 

 {Trentepohlia Mart. et auct. recent.). The character «filis simplici- 

 bus » does not agree with Trentepohlia and the relative length and 

 breadth of the cells is not sufficient to decide that a plant belongs 



Arten nenneu: Anlirrhinum saxatile und Thymus Zygis. Bei beiden ist auf 

 Autoritat des Linnéschen Herbars der Name auf Pflanzen ùbertragen, wel- 

 cbe Linné nacli Synonymie und Vaterland ursprunglich nicht gemeint haben 

 kann ■» .
