26 TRANSACTIONS OF THE [Sess. lxxvj. 



(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 (I.e.) figures a curious form of Sagittaria, var. 

 Bollei, 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 Sagittaria?- 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., 2 might well be excused in not referring it to Sagit- 

 taria; the leaves are all submerged, linear, varying in 

 length with the depth of water (6 dm. !), and 10 mm. wide. 

 This I have gathered in Surrey, and seen in Norfolk. 



A North-American species, S. heterophylla, Pursh, has 

 established itself in the River Exe, near Exeter, Devon. 3 



Sparganium. — Dr. Rothert has found in the late Mr. 

 Beeby's herbarium two specimens of Sparganium from 

 Shetland that recede from S. minimum and approach S. 

 hyperboreum, Laest., " Bih. i. bot. arsber," 1850. A species 

 of N. Finmark, S. Norway, N. Sweden, Finnish and Russian 

 Lapland, N. Finland, Iceland, Greenland, Labrador, and 

 Hudson's Bay. 



S. glomeratum, Laest., I.e. (S. fluitans, Fr.), is another 

 Scandinavian species that should be sought for ; this occurs 

 as far south in Sweden as Scania. 



In another work i Gltick's ideas are still further worked 

 out, and many figures (Nos. 324 to 379) are given of varying 

 forms, leaf and other sections. 



But in neither work are there any attempts to clear up or 

 collate the many other names under these species given in
