1890 & .91, and in 1907; sparingly in Castlelough Bay and 
between Swallow and Crow Islands, not far from Ross

First record for Ireland in 1890: R.W.S., Journ. of Bot., 
p. 111 (as NV. gracilis Agardh). 
The two Kerry lakes recorded above still remain the only 
localities known for this diminutive plant in Ireland. As it 
rarely much exceeds an inch in height and appears to grow 
in rather deep water, it is most probable that further in- 
vestigation of the numerous lakes elsewhere along the west 
side of Ireland will extend the range of this rare species. 
In Kerry it very seldom comes to the surface alone, being 
usually mixed with Naias flexilis or some other Nitella. 
Elsewhere in the British Isles, it has so far been found only 
in one station in the Outer Hebrides, where it occurs in a 
smaller and more compact form than in Kerry. Outside 
the British Isles it has a very wide distribution in North, 
Central and South Europe, as well as in North America and 
Australia.
