occupied till late in the evening with pressing and changing our spe- 

 cimens (which now amounted to a considerable number), preparatory 

 to starting, as we proposed, the next morning, for Malham-cove, Gor- 

 dale and Arncliffe ; the account of which, with the remainder of our 

 tour, we shall reserve for a concluding paper.

Art. CCXXXVIII. — Descriptions of New Mosses and Lichens from 

 the Australian Colonies. Written for the Botanical Society of 

 London, by Thomas Taylor, Esq., M.D.* 



The bundle of Musci and Lichenes, from a large miscellaneous col- 

 lection of the late Allan Cunningham, and placed at my disposal by 

 the liberality of Mr. Hewett Watson,t contained several duplicates 

 and but few species, and of these a very limited number that were 

 new. I proceed to notice and describe the most interesting. Hyp- 

 num arcuatum of Hedwig, to be found in very few collections, occur- 

 red growing on the bark of trees, at Norfolk Island. From New 

 Zealand was received Hypnum flexile of Hooker, which has not been 

 sufficiently distinguished from Leskea flexilis of Hedwig. From the 

 same place was sent Leskea concinna. Hooker, a variety, however, 

 much smaller than that figured either in the ' Musci Exotici ' or in 

 Schwaigrichen's Supplement ; the capsules, too, were not erect, but 

 drooping from the bending of the upper part of the seta. From Nor- 

 folk Island came Leptostomum erectum of Brown, in the same spe- 

 cimens varying singularly in the size of the capsules. It was most 

 pleasing to find gathered in New Zealand, Dicranum vaginatum of 

 Hooker, described in the ' Musci Exotici ' as coming from the elevat- 

 ed valleys of the Andes. Our common Usnea plicata, Ach., occurred 

 in New Zealand, and Sticta crocata, Ach., with fine apothecia, so rare 

 in Europe, was collected in an expedition to the interior of New South 

 Wales, under Major Mitchell. I proceed to describe the new species. 



Dicranum Menziesii, Tayl. Caule csespitoso, erecto, subramoso : 

 foliis undique imbricatis, erecto-patentibus, strictis, ex ovali basi 

 longius tenuiterque setaceis, apice subserrulatis, uninerviis : capsula

 f " The collection (consisting chiefly of vascular plants) was purchased at public 

 auction, after the death of Mr. Cunningham ; and it is very probable that some of the 

 specimens had been mingled together, though from different localities." — H. C. W.
