NOTES ON THE FLORA OF MIDDLESEX. 19 
this year and last. Of course it still exists, but Lemna minor had 
on each occasion, at the time of my visit, either hidden or 
supplanted it. 
Eleocharis acicularis is abundant on the margin of the Queen’s 
River in Bushy Park (in the broad part just before it passes under- 
ground), and on the north bank of the feeder, between the two 
ponds beyond. The record from “ Elstree Reservoir ” for this and 
so many other species is very misleading ; there is no such station 
Eriophorum polystachion. Boggy meadows near Uxbridge. : 
Carex pseudo-Cyperus, Colnbrook. Stanwell. Stanwell Moor, 
and pond by Woodfield House,, near Kingsbury Reservoir. 
Alopecurus fulvus. Frequent epee 1. Extremely abun- 
Avena pubescens is still more widely distributed than I thought. 
It follows the Colne river from the north-west boundary at Drayton

having already traced it over many square miles of the county, I 
am more than ever surprised at its exclusion from the Middlesex 
ora. 
Bromus secalinus var. velutinus. Field near Ashford Ford. 
Hordeum sylvaticum. Garret Wood (the only new record the 
excursion produced. - 
Equisetum maximum. In no place did I find this so abundant 
and luxuriant as just outside the north-east corner of Finchley 
Common, near the brickfield; but the deep hollows in which it 
grows were unfortunately being filled up. Several other species 
called ‘rare’? were found to be more or less frequent, and call fo: 
no special notice, as, for example, Sparyganium simplex, quite 
common from South Mims and Potter’s Bar to the extreme 
south of the county. : ee : : 
Many casuals and species evidently introduced with foreign 
seed were also frequently met with. Amongst those admitted into 
the British Flora and figured in Eng. Bot. were the following :— 
Camelina sativa. Uxbridge. West Drayton. Ashford Common. 
' . Lepidium Draba. Acton. Between Hampton Court and es
