The Irish Naturalist.

species are represented. It is to be noted that the habitat which he 

 gives opens a question as to whether he meant pumila or Alicularia 

 scalaris. The home of the former is " on rocks close to water ;" while a 

 favourite habitat for the latter is on bare ground at the edge of paths 

 and roads, and in such places, according to my experience, in Ulster, 

 Connaught, and Munster it abounds. My record of pumila is from Co. 

 Down, Moygannon Glen, near Warrenpoint, 1900, Lett and Waddell. 



Jungcrmania tolcrcnata, Schmid. {Jung. excisa,Sm. Kng. Bot., 

 t. 2497).— Templeton's records of excisa'' are, "growing on Divis 

 Mountain, the Black Mountain, Co. Antrim; Holywood Warren, Co. 

 Down ; , among Dicranum heteronialla in the Co. Derry." It was demon- 

 strated many years since in the " Transactions " of the Botanical Society 

 of Edinburgh, by Mr. Spruce and Dr. Carrington, that " we have no 

 such British species as Jung, excisa.^'' But Templeton collected the plant 

 that is figured and described in Smith's B. Botany under the name 

 excisa. Of this plant, which was the excisa of English botanists of his 

 time, Templeton gives a drawing, which is a good representation of 

 what is now known as Jung, bicrenata, Schmid. 



The figures in Smith and in J. Dickson's Plant Crypt. Bot., Fasc. 3, 

 p. II, t. viii., f. 7, to both which Templeton refers as his authorities, 

 are undoubtedly not excisa as at present known to European botanists, 

 but, according to my judgment, Jung, bicrenata. And what strengthens 

 me in this view is, that I have in my herbarium a specimen collected by 

 W.Wilson, and labelled in his handwriting excisa from Delamere 

 Forest, Cheshire, 1830," which is /. bicrenata. I am aware that Mr. 

 Pearson considers the excisa of Smith and Dickson to be the same as 

 capitata ; my reason for differing from this authority is that I have also 

 in my herbarium two specimens of /. capitata, Hook., collected and 

 labelled by W. Wilson in 183I; which are that plant, and not what he 

 named in the other specimen as excisa. 



/. bicrenata does not appear to have been often found in Ireland. I 

 myself have never met with it but at one place, " Co. Down, on road- 

 side between Scarva and Banbridge, on the vertical face of a rock (1900) ;" 

 it has probably been overlooked owing to its habit of getting coated 

 with dust to such an extent that all the leaves are concealed, and 

 nothing appears but the abundant capsules, which might easily be 

 passed over for the seeds of some phanerogam shed on the earth. 



Jungermanla barbata, Schreb. — There is a drawing by Mr. 

 Templeton (MSS.) of this plant made from a specimen gathered in the 

 Ness Glen, Co. Derry, June 20, 1809. It is a beautiful portrait, and 

 about it there can be no doubt. He also gives a sitfiilarly correct 

 drawing of what is now known as Jung, lyoni, Tayl., but which he and 

 succeeding botanists named Jmg. quinqttedentata, and his specimen was 

 *' found at Divis, March 26, 1813." But while the illustrations are 

 correctly named, a note about J. barbata by Templeton is not free from 

 the confusion that for long hung about this plant and /. lyoni. This is 

 the note — " /. barbata common in the perfectly procumbent state on the
