/3. maritima Duby 



y. littoralis Fr

1. prolifera (Bell. Act. tur. v. p. 247). Capitulis proliferis. 

 »j. den fata. Braeteis spinoso-dentatis acutis. In Olympo 

 Bithino. 

 It will be noticed that Brebisson's plant is not distinguished in 

 this list, while c is a stoloniferous South Italian form, £ a monstro- 

 sity, and i] an Eastern plant. This last is probably identical with 

 the Balkan J. Heldreichii Boiss. 



Willkomm and Lange (Fl. Hispanica, ii. p. 280 (1870)) introduce, 

 two new varieties under ./. montana, at the same time defining with 

 some accuracy the specific type. 



The first variety, j3. echinata, already described as a species t>v 

 Boissier, is a tall, erect, and usually very hirsute plant, with rather 

 large flower-heads, frequently bluish-tinted bracts, and very long, 

 rigid calyx'-teeth. The second variety, gracilis Lange, Pugillus, 

 p. 155 (1866), is a dwarf, slender but erect form, with very small 

 heads, borne on long peduncles and enclosed in broad bracts. 



The variety maritima Duby is transferred by Willkomm and 

 Lange to the Pyrenean J. humilis Lois. 



In Rouy's Flore de France, x. p. 91 (1908), the arrangement 

 under J. montana is : — 



/3. littoralis Fr (littoral de l'Ocean et de la Mediter- 



ranee ; Corse). 



Subvar. nana (Gr. & Gr. pro var.). Plante trapue, a 

 tiges de 2-10 cent., tres herissees, capitule gros. 

 y. Borcei nob. Plante grele, naine (2-6 cent.) ; capitules 



tres petits ; fleurs sessiles. (Creuse.) 

 I. Timbali nob. (var. gracilis Icanb. & Timb. Llaurenti, p. 227, 

 non Lange). Plante basse, diffuse, a tiges greles ; capi- 

 tules tres petits ; involucre a fol. ovales-acuminees, 

 entieres ; calice glabre ; fleurs a pedicelles egalant les 

 divisions du calice. (Pyrenees.) 

 r. major Mert. & Koch. . . . (ca et la, vallees boissees et 

 humides). 

 Race (maritime) J. maritima Duf. (pro spec.) ap. DC. Prod, 

 vii. p. 415 (J. montana y. maritima Duby, Bot. Gall. i. p. 311, non 



Breb. ; J. humilis y. maritima Willk. Fl. Hisp. ii. p. 283) 



(Sables maritimes de l'Ocean.) 



Race (mediterraneenne) J. mediterranea Rouy. Se distingue du 

 J. maritima .... par tiges glabres et longuement nues superieure- 

 ment . . . . ± longues (8-30 cent.) ; folioles de l'involucre epaisses, 

 glabres, fortement dentees. (Corse.) 



Still more recently a further variety, sabularia, has been described 

 in Coutinho's Flora de Portugal, p. 603 (1913). This is charac- 

 terized by an ascending habit, with many simple or slightly branched 

 steins, and moderate-sized heads on relatively short peduncles. It is 

 represented bv one poor example in the National Herbarium.
