VIII. & IX. Along both sides of the River Cashen, from 
near the Ferry bridge south of Ballybunnion, to near Dysert 
Church, abundant at intervals for a distance of about three 
miles : R.W.S. 1890, and in 1904.

This appears to be one of the most local plants in the Irish 
flora, as, apart from the locality given above, it is known to 
occur only about the mouth of the river at Arklow on the 
Wicklow coast. In Great Britain this plant is found in two 
or three localities along the south coast of England and in 
one in North Wales. Owing to its diminutive size it is a very 
easy plant to overlook, while the tidal nature of its stations 
often renders their examination impossible.

Although much rarer inland than by the sea, this plant is 
not infrequent about the Killarney Lakes and elsewhere in 
the county. The var. MonosracHys has been gathered near 
Smerwick Harbour, &c., mingled with the type.
