with which it is probably frequently confoimdecl) by the following 
characters : — I. Pseiidacoriis, lioreau. Outer perianth-segments of 
a uniform clear yellow colour : blade broadly obovate ; claw rather 
short ; stigmas long and narrow. — I. acorifonnis, Boreau. Blade 
of outer perianth segments nearly orbicular, a deeper blotch at 
base ; claw long, greenish yellow marked with prominent violet- 
purple veins ; stigma shorter and broader than in last-named, and 
the yellow of the flower almost a shade less deep.” — G. Nicholson. 
Carex vmricata var. pseudo-divnlsa. Name authenticated by 
Dr. Boswell. “ (Root from Lauder, Berwickshire), June, 1878. I 
brought the plant several years ago from a Avood near Lauder, and 
planted it alongside a idant of the common C. muricata of the 
district. At all times they look very different, this being much 
the strongest groAver, and also a good deal earlier in flowering 
than muricata." — A. Brotheeston. Mr. Charles Bailey sends the 
same plant from a lane at Pepplesham, near St. Leonard’s, Sussex. 
C. ])unctata. Dr. Trimen points out that a plant so labelled, 
gathered by Mr, SteAvart on rocky shore at Dingle, Kerry, is 
properly a small form of distayis. 
Panicum Crus-gaUi. Tweed-side, Roxburghshire, abundant in 
1878; introduced with foreign avooI. — A. Brotheeston. 
Leersia orijzoides. Ditch on Shalford Common, near Godaiming, 
Surrey, A. Bennett. A new station. 
liromus Benekenii. “ Garden groAAUi; root from Eaton Bishop, 
Herefordshire, July, 1878, A. Ley. This appears to be correctl}' 
referred to B. HenckenU, Lange, differing from that plant mainly in 
its greater luxuriance and more ample panicle, the result probably 
of garden cultivation. Specimens of the original AAuld plant, 
with notes on its locality and distribution, Avould be of great 
interest.” — H. Trimen.

the Avest end of the Calf of Flotta, Orkney, August 2, 1878. 
Discovered on the above date by Mr. Wm. A. Irvine Fortescue. I 
have seen two specimens of this plant from near the Black Crag, 
Stromness, Avhere Miss Patricia Deuchar first found it in 1877. 
These tAvo stations and Dr. BosAA^ell’s one at Veness, and that at 
Swanbister, in Orphir, are all at the seashore.” — H. Halcro
