HAB. King's Park, Edinburgh, where it appears to have 

 been first discovered by R. Brown, Esq. many years 

 ago. Dr. GreviUe finds it there in great abundance 

 upon the trap rocks. At Fairhead, on basalt, Coast of 

 Fife. -Mr. Arnott, 



The broad tufts of this plant, have, when dry, a singularly 

 hoary appearance upon the dark trap rocks, in consequence of 

 the long hair-points to their leaves. The lower leaves of all are, 

 however, destitute of hairs and broader than the upper ones, 

 which are almost exactly elliptical, and very similar indeed to 

 those of Gr. pulvinata ; but then the seta is straight and the 

 capsule is smooth. Thus this plant has the leaves of Gr. pul- 

 vinata, and the fruit of Gr. ovata. 



9. Gr. ovata ; stems more or less elongated, leaves lanceolato-sub- 

 ulate gradually produced into long diaphanous hair-like 

 points, their margins recurved, fruitstalk exserted, capsule 

 ovate, teeth of the peristome often perforated and split, lid 

 rostrate. (TAB. XIII.)
