Fordham: On the Occurrence of Pedicularis palustris L. 255 
riant growth of rushes, sedges and horsetails, with here and 
there a more open space carpeted by an aquatic Ranunculus 
in some places, and by Water Violet ( Hottonia palustris L.) 
in others. These drains are very dry this year, and are not 
cleaned out as well as they should be. However, it is the 
character of the vegetation of the meadow land that concerns 
us at present as the Lousewort did not occur in the drains 
at all. The areas shewn on the plan were practically solely 
covered by the Pedicularis, though there was abundant evidence 
that previously Caltha palustris L. had here held sway. Other 
areas, as indicated, were occupied by Pedicularis palustris as 
a dominant species, but various components of the surround- 
ing vegetation were also to be found. The dominant plants 
at present (exclusive of grasses) in the carrs generally are 
Ranunculus acris L., R. repens L., and Trifolium pratense L. 
Previously, Caltha palustris L. and Cardamine pratensis L. 
had been dominant, and were fruiting. 
The sub-dominant plants appeared to be :— 
Ranunculus flammula L. Festuca pratensis Huds. 
Lychnis flos-cuculi L. Lolium perenne L. 
Senecio aquaticus Hill. Anthoxanthum odovatum L. 
Rumex acetosa L. Poa pratensis L. 
Eleocharis palustris Br. Phleum pratense L. 
Carex paniculata L. and 
Carex acuta L. Alopecurus geniculatus L. 
Other plants commonly occurring and very little less 
frequent than the preceeding thirteen species were :— 
Lotus corniculatus L. Spivea Ulmaria L. 
Sangutsorba officinalis L. (Enanthe crocata L. 
Silaus flavescens Bernh. Plantago lanceolata L. 
Rhinanthus crista-galli L. Prunella vulgaris L. 
Myosotis palustris Hill and its var. and 
stvigulosa Rchb. Equisetum palustre L. 
The following grasses, etc., were also obtained — 
‘Cavex disticha Huds. Festuca vubra L., and 
Anthoxanthum odovatum var. villo- | Festuca pratensis Huds. x Lolium 
sum Lois. perenne L. 
Several of the above have been verified either by Dr. 
Drabble, F.L.S., or by Mr. J. F. Robinson. 
I shewed the Lousewort to Mr. Wilfred Hutchinson, of 
Gunby, and he tells me that seventeen or eighteen years 
ago it appeared in abundance in the ings on their farm, which 
is about a mile and a half down stream on the other bank. 
It persisted for three or four years in diminishing numbers, 
and eventually died out, and he has not seen it since. He 
attributes this extinction to mowing the hay before the seed 
rgil July 1.
