extend to the calyx-teeth. They appear to be readily deciduous, fur 

 I have seen no calyces in fruit that are not glabrous. 



In British botany no endemic varieties of Jasione montana have 

 been established, but plants similar to the large-headed form that I 

 noticed near Ilfracombe have been referred to Koch's variety major 

 by Beeby, E. S. Marshall, and others, and a dwarf prostrate form 

 occurring on the sand-hills about Bournemouth has been identified by 

 Tovvnsend with var. littoralis Fries. In Maereight's Manual of 

 British Botany, p. 146 (1837), a shore form from Portsmouth is named 

 var. maritima DC. ; and Mr. C. E. Salmon, at p. 321 of this Journal 

 for 1917, has referred to the same variety a plant collected on the 

 rocky coast of Holyhead. In the ninth edition of Babington's 

 Manual (p. 272) Messrs. Groves also note the occurrence in Shetland 

 of a dwarf form with large leaves and very large heads. 



The number of varieties of J. montana distinguished by Conti- 

 nental authors is considerable. The earliest of these is var. major 

 Mertens & Koch, Deutschl. Fl. ii. p. 147 (1826), the diagnosis of 

 which runs : " Viele sehr astige Stengel entspringen aus einer starken 

 Wurzel und sind uber 2', folglich mehr als noch einmal so hoch als 

 bei der gewohnlichen Form ; die Bluthenkopfe sind noch einmal so 

 dick und die Hiille ist aus mehreren und starker gezahnten Blattchen 

 zusammengesetzt." No habitat is given, but in Koch's Synopsis Fl. 

 Germ. p. 463 (1837) this is supplied — " In rupium fissuris montium 

 porphyriorum ad fluvium Nahe Pilatinatus." 



The variety littoralis Fries was established in Novitia? Fl. 

 Suecicae, ed. 2, p. 269 (1828), with a description " Radix fusiformis, 

 perennans videtur. Caules in densum caespitem collecti, simpli- 

 cissimi, prostrati, superne aphylli, adscendentes, digitales. Folia 

 plana, glabra ; caulina majora, sparsa, uninervia. Capitula duplo 

 triplove minora, foliolis involueri ovatis obliquis obtusis integerrimis. 

 Raro subhispida ... In arenosis maritimis Sueciae occidentalis. . ." 



In 1828 this species was also dealt with by J. E. Duby in 

 De Candolle's Botanicon Gallicum, ed. 2, i. p. 311, where three 

 A'arieties are diagnosed, viz. : — 



a. loevis. Caule ramosissimo erecto, foliis glabriusculis, 



calyce glabro. 

 fi. hirsuta. Caule vix ramoso, hirsuto, foliis hirsutis. in- 



volucris aeutis, calyce subglabro. 

 y ? maritima. Incano-pilosissima, caule prostrato subsimplice, 

 foliis brevibus, involueri squamis exterioribus obtusis, 

 calycibus hirsutis. In maritimis Gallia? occidentalis. An 

 distincta species ? 



A. second variety maritima, seemingly different from Duby's 

 plant, appeared in 1836 in Brebisson's Flore de la Normandie, p. 179, 

 and is described as " Tige basse, tres velue ainsi que les feuilles, qui 

 sont courtes ; capitules larges. Roc de Granville." Of this variety 

 Corbiere (Fl. de la Normandie) remarks: " Plante basse (3-10 cm.), 

 herissee," and Lloyd (Fl. de I'ouest de la France) adds: "fleurs 

 plus pales " [than the type]. 



In De Candolle's Prodrovwa. vii. p. 415 (1839), the varieties of 

 Jasione montana stand thus : —
