Hebrides Isles. 
Outer Hebrides'. North Uist (British Mus.). 
Inner Hebrides : Pool near Broadford on Skye; Isle of Islay; east of 
Loch Fada on the Isle of Colonsay ; Isle of Coll ; Isle of Tiree (Bennett’s 
Herb.). 
As final result the following emerges from the above compilation : 
U. ochroleuca is a plant widely distributed in Great Britain and the 
islands about it. The centre of distribution is in Scotland ; no territory of 
Europe can show so many stations for U. ochroleuca as Scotland. And if 
from its geographical distribution we consider the conditions of its station 
the following results : U. ochroleuca is a plant adapted to a cold climate, 
as the Scotch Highlands typically yield, and for that reason U. ochroleuca 
has its chief distribution in Scotland, for which I have indicated about forty 
localities. On the other hand, U. intermedia is a plant adapted to a much 
warmer climate, and is wont to inhabit low-lying swampy land. U. inter- 
media is therefore not a very rare plant in warm or temperate West Ireland 1 
and in the lowlands of England, and there takes the place of U. ochroleuca , 
but in Scotland it is a very rare plant. In fact I could cite U. intermedia 
only for four Scotch places, belonging to Forfarshire and Perthshire : (1) for 
Rescobie, near Forfar (British Mus.); (2) for Kinclaren (Devonian Perth); 
(3) for the curling pond, Meurton Wood (Rattray) ; (4) for a marsh on the 
east side of Alyth (Nat. Hist. Mus. at Perth). 
May this small essay be the means of directing the interest of the 
English botanists to this up to now neglected water-plant. 
To all those who have helped me in the preparation of this article 
I wish to render here my special thanks ; above all to Mr. Edward S. 
Marshall (Taunton), to Mr. Arthur Bennett (London), to Dr. A. B. Rendle, 
Keeper of the Plerbarium of the British Museum, and to Mr. M. Rodger 
(Perth).

PLATE XLVII. Figs. 1-8. 
Fig. 1. A form of the shallow water from the Konigsveen in Holland. The horizontal green 
water-shoot bears water-leaves on which here and there isolated bladders occur ; besides which 
two colourless underground shoots (s t and s 2 ) are present, the ‘leaves’ of which all bear bladders. 
Shoot S x is originating from a former rhizoid ; the little segments /, / are former rhizoid segments. 
The flowering stem is furnished with two flowers and three barren scales (= s). Nat. size. 
1 I myself found the true U. intermedia in pools between Recess Hotel and Recess Station, 
near Ballynahinch, and in the Craigga Moor near Roundstown (Connemara).
