flowers and seed, have lived through the winter— are in fact 

 biennial." This ingenious and attractive theory must, I fear, be 

 rejected. Early in last spring the Rev. E. F. Linton showed 'me 

 the Durlstone Head station for this plant, which we found to be 

 springing up in seedling form, just like any other annual.— Edward 

 S. Marshall. 



Lowest Limit of Vaccinium Vitis-id.ea in Ireland (p. 88).— In 

 declining to accept Mr. H. C. Hart's estimate of 900 ft. as the 

 lowest elevation, in Ireland, of Vaccinium. Vitis-idaa, Mr. More is 

 amply justified. Templeton's records of Lough Neagh and Creve- 

 tenant may be left out of the question, though there is every reason 

 to accept them as correct, notwithstanding that the great decrease 

 of heiithy wastes in the northern counties renders modern con- 

 firmation improbable. In the Flora of North-east Ireland the range 

 of this species is given as 500-2100 ft., the former limit referring 

 to Easharkin, in Co. Antrim, where I have known it for thirteen 

 years. It there occupies two spots, one being under, and the other 

 slightly exceeding, 500 ft. The late Admiral Jones found the 

 plant in question near Drumquin, in Co. Tyrone. This record is 

 not as definite as could be desired; but Drumquin is at an elevation 

 of about ^50 ft., and any ground which could properly be said to be 

 near Drumquin ranges irom 250 to 400 or 500 ft. In all likelihood 

 the Tyrone station is as low or lower than the Easharkin locality.

Sonchus palustris L. — I found two plants of this rare species 

 in flower on 3rd August, 1889, in the reed-bed between the north- 

 east corner of Woolwich Arsenal wall and the river. They were both 

 fine specimens, seven or eight feet high, in full flower, and very 

 characteristic. I think the plant may have been overlooked in 

 recent years in the habitat which is mentioned by Boswell- Byrne in 

 English Botany, vol. iv., not that it is wanting in conspicuousness, 

 but on account of the difficulty of getting on to the reed-bed. It is 

 insulated, except at low tide, and then it is surrounded by a muddy 

 ditch with slimy banks, which must be jumped standing. The 

 reeds also are cut most years at about the time S. palustris would 

 flower. I saw the same two plants again in 1890, but they were 

 cut before flowering. I was unable to find them last year, though 

 I could locate the spot almost exactly. My father has tried to 

 establish foreign plants of this species by an artificial pond in 

 private grounds in Cheshire, but they were all eaten by water-rats, 

 who seem to be very fond of it. — A. H. Wolley Don. 



Trichomanes radicans in Co. Tyrone. — This plant was found 

 last year by my brother, Mr. G. G. Delap, within five miles of 

 Strabane, Co. Tyrone. The locality faces almost west, and is 

 shaded from the sun. There appeared to be three large tufts or 

 plants within a small area. — Alex. H. Delap.
