22 THE SCOTTISH BOTANICAL REVIEW 
this species in herbaria? I have been unable to see one, but 
Hooker and Arnott? give ‘‘ Black Loch, 6 miles from Stran- 
raer,’ Wigtown; and in the 2nd ed. of “Topl. Botany,”’ 
‘‘ Ayr, Duncan cat.” is added. Mr. Scott-Elliot? does not 
notice the species at p. 164, though he gives all Wigtown 
species. That it is often misnamed is certain, as for some 
years Ireland was credited with it, but it has been found to 
be a submerged state of A. ranunculoides. It is certainly to 
be found in seven Welsh counties, and in two English (ze. 
Salop! and Chester !), and perhaps in two others (York and 
Cumberland). Dr. Gliick divides this into f zypzca, Asch. et 
Graeb.; f. sparganifolius, Fries; f. repens, Asch. et Graeb. ; 
and f/f. terrestre, Gliick. 
13. Sagztturia sagittifolia, L.—Glick divides this into 
J. typica, Kilinge ; f natans, Klinge ; f cerrestris, Bolle ; and 
J. vallisnerifolia, Coss, et Germain. 
Why is Sagzttaria so rare in Scotland? Two counties 
only are given, and Messrs. Kidston and Stirling added 
Stirling. Yet in Scandinavia it occurs from S. Sweden 
(Scania) up to Norland, and is not uncommon in Finland up 
to 67° 50° N. lat. is absent from Finnish Lapland, but 
reported from Umba in Russian Lapland, and S. Norway. 
Kirchner (Z¢.) figures a curious form of Sagztfaria, var. 
Boller, Asch. et Graeb., which I gathered near Croydon in 
1888. In this the three lobes of the leaf are only 4 mm. wide, 
and the basal lobes at an angle of 45°; the leaf-petioles are 
more succulent, and show the transverse partitions strongly 
when dry. 
The plate (Tab. 2) that accompanies the classic account 
of Sagzttaria,* with its details, is quite up to many of the 
recent drawings of aquatics, and far beyond most. The 
protecting sheaths of the stolons are in fig. 1 beautifully 
drawn. 
Anyone gathering the var. vallisnerifolia, Coss. et Germ., 
might well be excused in not referring it to Sagittaria; the 
leaves are all submerged, linear, varying in length with the
