BOTANY. 
Mercurialis perennis and Draba muralis in Co. Antrim. 
The two stations— one in Down and one in Antrim — given in Irish 
Topographical Botany, seem to be the only ones in the north-east where 
Mejrtirialis perennis has been seen recently. On the 25th April I had the 
pleasure of meeting with it in fair abundance in another Antrim locality. 
This was on the steep, shady banks of the Craigban burn where the latter 
joins the Glenshesk river, about half a mile below the Glen viaduct. As 
the exact spot is rather inaccessible, the plant may easily escape notice. 
The station, however, is, I am certain, merely a re-discovery, for the 
plant was recorded over forty years ago in the Flora of Ulster from 
" Altaferna Glen, near Ballycastle," and the place where I found it is not 
only within four miles of Ballycastle, but I find from the old 6-inch 
survey map of the period that the Craigban burn is, in its upper part at 
least, described as " Altiffirnan Glen." The re-finding, however, is an 
interesting verification. With regard to the Co. Antrim station in Irish 
Topographical Botany, it should read Glynn rather than " Glenoe." The 
plant occurs on the south bank of the Glynn river, near the village, and 
almost opposite the church. It is a couple of miles east of Glenoe proper. 
On the same day I had the good fortune to see for the first time that 
ver}' rare plant Draba mtiralis. It occurs abundantly on an old wall at 
the bridge over the Bush river, a short mile east of Armoy, and not far 
from the round tower. It seems to have been in an equally plentiful 
and luxuriant condition on the same wall ten years ago when it was first 
discovered by the Belfast Naturalists' Field Club. It was in full flower 
when I saw it, and a very pretty sight. Its situation here seems to favour 
strongly the supposition that the plant may perhaps be truly indigenous 
to Ireland.

A colour-variety of Pinguicula grandiflora. 
Miss lyucila O'Connell sends a fresh blossom of a beautiful pale lilac 
form oi Pingtdctda grandiflora, of which she has found three plants on the 
shore of the Lower Ivake of Killarney. I do not find any mention of 
colour variation in this species, though I have notes of white, lilac, and 
white-tipped varieties of its ally P. vulgaris.
