AQUATIC FORMS AND SPECIES OF THE BRITISH FLORA 21 
We now come to a series of aquatics which Dr. Gliick has 
treated. 
He here treats the plants under their growth and evolution. 
9g. Alisma Plantago, L.—He divides into two varieties— 
latifolium, Kunth, and lanceolatum, Schultz ; again dividing 
these into two forms each—aguaticum, Glick, and terrestre, 
Glick. 
The var. graminzifolius, Wahlb., he gives as a species 
A. graminifolium, Ehrh., dividing it into four forms: 
angustisstmum, Asch. et Graeb. ; typicum, Beck-Managetta ; 
terrestre, Glick ; and pumlum, Nolte. 
10. A. ranunculordes he places under Echznodorus, dividing 
it into five forms: typzca, Gliick ; natans, Glick ; zostertfolius, 
Fries ; zerrestre, Glick; and pumzlus, Glick. He then takes 
the var. repens (Lam.) and divides that into four forms. 
No doubt many of these phases of plants may be found 
among Scottish specimens. I have A. graminztfolium from 
Perth, Dr. B. White sp.; and Mr. West found it in Loch 
Gelly, Fife, as the f typzca. 
The var. zostertifolius, Fries, in “Bot. Notiser” (1840), 
p. 35, “foliis longissimus linearibus natantibus (fran Oland, 
Sjoshand) ar en markvardig med Al. Plantago graminif. 
analog form.” 
Mr. West gathered this in Loch Corsock in S.E. Kirkcud- 
bright, where “it flowered under water at a depth of 3 feet ; 
without the flower-stalk these submerged forms look ex- 
tremely like J/soetes lacustris.” The Rev. E. S. Marshall? 
gathered it from “peat-holes above the Beauly river, E. 
Inverness, 1892.” 
Mr. West found the “/ ¢errestre at Loch Leven 1} inches 
high.” 
11. A. parnasstfolia, Bassi (Caldasia parlatore) has lately 
been found in Bavaria,* but I suppose we can hardly expect 
it in our isles. It has deeply cordate leaves, and only 6 to 9 
carpels. 
12. Alisma natans, L.—Are there any Scottish specimens of 
1 In “Allg. Botanische Zeitschrift” for 1906, under ‘“ Systematische 
Gliederung der europdischen Alismaceen.”

(1850), p. 253.
