At a subsequent period of the year Captain Hutton was fortunate in 

 finding Trichostomum sinuosum (Wilson) growing on wet stones in the 

 rivulet which runs through the Phoenix Park, in the glen near Knock- 

 maroon Gate. This is the first record of the plant having been found 

 in Ireland ; but, on looking over some specimens collected in the same 

 place where Captain Hutton found it, by Mr. D. Orr, several years ago, 

 the Trichostomum is among them, marked, as a variety of Didymodon 

 cylindricus (Bruch et Schimper), to which the former plant bears con- 

 siderable resemblance. 



Grimmia ovata (Web. et Mohr) was also found by Mr. D. Orr, in a 

 barren state, on the rocks of Killiney Hill, ten years ago, in which 

 place it has been lately seen again, and ascertained to be that species. 



"When at Lough Derg, near Portumna, last August, I collected 

 Phascum cohcerens (Hedwig), on wet banks by the side of the Shannon, 

 that being the first instance of the species having been recognized in 

 Ireland. Pottia minutula, variety B. rufescens, was also growing near on 

 on moist ground, which is annually under water a considerable period of 

 the year. Bartramia ccespitosa (Wilson) was collected in small quantity 

 last September, growing on moist banks on the ascent to Lugnaquilla 

 from Glenmalur, county of Wicklow, in company with Dr. Barker and 

 Mr. Archer. I may here mention that I was fortunate enough to pick up 

 this newMoss in fruit on the Dovrefjeld, in Norway, in July, 1863, that 

 being the only instance, I believe, of it having yet been seen in that 

 state. 



Pottia Wilsoni — On a dry bank at Howth, 1856. This is the plant 

 which I recorded as Pottia crinita (Wilson), in the " Proceedings of the 

 Dublin University Zoological and Botanical Association." The true 

 P. crinita has not been discovered in Ireland, though both Mr. Wilson 

 and I took our Howth plant to be it at the time mentioned. I am 

 therefore glad to have this opportunity to correct the error. 



Among Hepaticse, I have to notice the discovery of Scapania cequi- 

 loba (Nees.), Jungermannia cequiloba (Hubener), &c. I collected good 

 specimens of this plant about three weeks ago on wet rocks above Kelly's 

 Lake, on the ascent from Glenmalur to Lugnaquilla, county of Wicklow. 

 Dr. Carrington informs me that he also finds it in Yorkshire, where it 

 is not very rare in subalpine districts. It may be known from large 

 states of Scapania (Jungermannia) nemorosa by the more slender stems, 

 nearly equal throughout, and by the pale fawn or olive colour of the 

 leaves. 



Scapania undulata, variety A. major (JSTees.) ; this fine plant, with 

 stems four or five inches long, and leaves of a deep purple colour, 

 which are strongly ciliated, is near to Scapania undulata, variety E. 

 speciosa (Nees.), Scapania planitulia (Hubener), Uepaticce Germanicce. 



Before concluding this brief list of addenda to our Flora, I desire 

 to place a record on our " Proceedings' ' of the discovery of an interesting 

 phcenerogamic plant, Inula salicina, which has already been, made 

 known to the public through " Seeman's Journal of Botany," where it 

 has been figured and described in No. 38, for February, 1866. I first
