386 Wilson's notes on British muscology. 



H. atrovirens. It has since been gathered near Warrington. 

 Fruit ripe in April. 



55. H. rugiilosum. — Fertile specimens gathered at Beaver 

 Lake, are given in Drummond's Miisci Americani, No. 198, 

 though not noticed in Hook. Br. Fl. Capsule cylindrical, 

 very much bent. Operculum conico-rostrate. Seta smooth. 

 It is a true Hypnum, 



Notes on the Hepattc-e in Hooker and Taylor's Muse. Brit. 



1. Spheerocarpus terrestris. — Fine specimens of this plant 

 gathered by the late Thomas Drummond in Louisiana, prove 

 that the capsule is covered (as is usual) with a calyptra, which, 

 however, from its extreme tenuity can only be detected in an 

 early stage. The anthers are found in folliculose bodies 

 covering the upper surface of the nerve on separate fronds. 



2. \\\cc\Q.fluitans, — Abundance of this plant, in a perfect 

 state of fructification, was found by the writer, in September, 

 1834, on the dried shores of a lake called Mere in Cheshire. 

 It is a true Riccia. 



3. Jungermannia ianceolata, Lin.; Hook. Jung. 1. 18 Until 



very lately, this species has been regarded as very doubtfully 

 British. It has, however, been recently gathered very sparingly, 

 on Harrison's Rocks (Tunbridge Wells?) by Mr E. Jenuer, 

 whose specimen agrees exactly with No. 527, of Mougeot 

 and Nestler. 



4. J. sphcerocarpa, and J. hyalina. — Satisfactory characters, 

 by which these two estimated species may be distinguished, 

 are much wanted. 



5. J. inflata^ and J. turbinata. Wils At the time when 



the writer described J. turbinata in the Svppl. to Engl. 

 Bot. he had not access to the orio-inal work, and it now 

 appears that J. turbinata, which is certainly distinct from 

 J. infafa of Hook. Brit. Jung. t. 38, has been twice figured 

 in Engl, Bot., first at t 2519, under the name of J. inflata, 

 (which figure has been erroneously quoted in Hook, and
