On heaths and on wall-tops that are covered with earth. 9>. on 

 mountains. Fr. Spring.— The P. striatum of the excellent Menzies is 

 indeed a more elongated and slenderer plant than the usual state of 

 P.juniperinumi but the P.alpedre of Hoppe and Schwaegrichen is 

 exactly a connecting link.— It will be seen by the essential character 

 how closely this species is allied to the preceding. 



5. P. septentriondle, Sw. ( northern Hair-Moss); leaves linear- 

 subulate obtuse their margins especially towards the top invo- 

 lute subserrulate, capsule ovate subangulate, apophysis obsolete, 

 lid conical acuminate. Su\ Muse. Suec.t. 9.f. 18. Schwaegr. Suppl

Summits of the highest Scottish Alps. Fr. Aug.— Its fnictijicationis 

 exceedingly rare and only found on the Cairngornm mountains; 

 Greville, Arnott, Hooker. Plentiful there in 1830, which had been a 

 very wet season (Grevillc). — The leaves are very obtuse and much 

 incurved, scmicylindrical. Seta very thick and succulent. Capsule 

 scarcely angular. It is a very alpine and a very arctic moss. 



ff Leaves serrated, their margins plane. 



6. P. commune, L. (common Hair-Moss); stems elongated, 

 leaves patent linear-subulate their margins plane serrated as 

 well as the points of the keels, capsule oblongo-quadrangular 

 wiili an evident apophysis. Muse. Brit. ed. 2. p.47.t. lo.—
