12 GYMNOSTOMUM. 



G. ovatum. Hedwig. St. Cr. v.l.t. 6. Turn. Muse. Hib.p. 9. Engl 

 Bot. t. 1889 Moug. et Nestl n, 308. 



ft. gracile; capsule oblong. 



HAB. Banks and walls. 



This is a species which varies much in the length of the 

 fruitstalk, and also of its capsule ; but it may alwavs be 

 known by the concave, obtuse, and piJiferous leaves, and 

 especially by their nerve, which in the upper part is fur- 

 nished with one and sometimes two large oblong mem- 

 branous appendages, to the surface of which are attached 

 minute greenish bodies (gemmcs?). This peculiarity ap- 

 pears to have been noticed by no other muscologist but' 

 Hedwig, who has both described and figured them in his 

 Sfirpes Crypt. 



1 . G. truncatulum; leaves ovate, apiculate, patent, nearly plane; 

 lid obliquely rostrate. (TAB. VII.) 



G. truncatulura. Hoffm. Germ. v.2.p.27- Turn. Muse. Hib.p. 7- 

 Engl. Bot. t. 19/5. G. truncation. Hedw. St. Cr. v. 1. t. 5. Moug. et 

 Nestl. n. 114. Bryum truncatulum. Linn. G. intermedium. Turn. 

 Muse. Hib. p. 7. t.l.f. a. Engl. Bot. t. 1976. 



HAB. On banks and walls. 



The British G. intermedium differs from G. truncatu- 

 lum only in the longer and more ovate form of the capsule, 

 which is turbinate in the latter. 



8. G. Heimii; leaves lanceolate, serrated at the point; capsule 



ovato-oblong ; lid obliquely rostrate. (TAB. VI I.) 



G. Heimii. Hedw. St. Cr. v.l.t. 30. Turn. Muse. Hib. p. 9. EngL

Hib. p. 9. Engl. Bot. t. 1407. 

 HAB. On moist banks. 

 The Gymnoslomum obtusum is not that we can find at 



all different from G. Heimii, which, being the older name, 

 .we retain. 



9. G. conicum ; leaves oblongo-obovate, apiculate ; capsule 



ovate; lid conical, obtuse. (TAB. VII.) 



G. conicum. Schwaegr. Suppl. t. 9. 



HAB. Fields near Cork. 



Mr. Drummond only has found this plant near Cork. It 

 is scarcely to be distinguished from Weissia Starkeana but 

 by the absence of the peristome. The shape of the lid is 

 very different from that of G. truncatulum, than which it 

 is likewise much smaller. 



10. G. fasciculare ; leaves oblongo-acuminate, nearly plane, 

 sub-serrated, marginated; capsule pyriform; lid plane, sub- 

 mammillate. (TAB. VIII.)
