simples' voluntarily expose themselves, for the sake of 

 adding one or two new specimens of plants to the 30,000 or 

 40,000 species already known. Thus, in the midst of snow, 

 and without a tent, sheltered only from the inclemency of 

 the weather by a hut built of the branches of trees, and 

 depending for subsistence from day to day on a solitary 

 Indian hunter, ( I obtained,' says the amiable and enthu- 

 siastic Mr DRUMMOND, ( a few mosses; and, on Christmas 

 day, I had the pleasure of finding a very minute Gymnos- 

 tomum, hitherto undescribed.' We shall not, we hope, be 

 classed with those who see nothing but food for merriment 

 in such devotion in the true heroism of science." Quart.

* * Fringe with ciliary processes. 



4. O. crispum, stems erect, branched ; leaves narrow-lanceolate, 

 crisped when dry ; fruitstalks much exserted, thickened upwards ; 

 capsule furrowed when mature ; ciliary processes 8 ; calyptra very 

 pilose. 



Hob. On trees in deans, common. 



Orth. Bruchii and crispulum of some foreign botanists are com- 

 mon varieties of this species. 



5. O. pulchettum, stems erect, short ; leaves spreading, narrow- 

 lanceolate, somewhat crisped when dry ; fruitstalks exserted ; 

 capsule furrowed ; ciliary processes 1 6 ; calyptra scarcely pilose. 

 WINCH, Guide, ii. 23. 



Hob. On trees, in neat tufts. On hazels in Longridge- 

 dean. Wooded banks of the Tweed above Lady-kirk. 



This, the most elegant of the genus, is generally said to have 

 been discovered by Mr BRUNTON ; but his specimens were 

 communicated by Mr WINCH, who, at the time, was aware 

 of their belonging to an undescribed species. 



6. O. affine, stems erect, branched ; leaves spreading, lanceolate, 

 erect and close when dry ; fruitstalks not raised from amongst the 

 leaves ; capsule cylindrical, furrowed ; ciliary processes 8 ; fringe 

 reflected ; calyptra sub-pilose ; lid tapered gradually into the beak. 



Hob. On trees and on stones, common. 



7 O. rupinicola, stems erect, branched ; leaves broadly lanceo- 

 late, somewhat spreading, erect when dry ; fruitstalks not raised
