620 Gliick. — The Species of Utricularia of Great Britain . 
Fig. 2. Another form oi shallow water from the Loch nan Mathair Etive on the Rannoch Moor 
in Scotland. This form is very similar to that of Fig. i. Nat. size. 
Fig. 3. A floating form growing in deeper water. The internodes of the green water-shoots are 
elongated and the leaves are longer and more tender than in Figs. 1 and 2. Two isolated bladders 
are visible on the water-shoot. The two colourless shoots show the tendency to change into 
water-shoots. From the Loch nan Mathair Etive in Scotland. Nat. size. 
Fig. 4. A magnificent form, which floated in moderately deep water ; the horizontal water-shoot 
bears three isolated bladders. The two vertical shoots represent, as they are not fixed in the mud, 
a transition to water-shoots. From little pools near Boat of Garten. Nat. size. 
Fig. 5. A water-shoot of U. intermedia bearing a winter-bud at the top, whilst its axis is covered 
with many intermediate leaves, the terminal segments of which are distinctly denticulated. From 
Norfolk (Barton Turf). Nat. size. 
Figs. 6-8. Rhizoid formations. 
Fig. 6. Base of the flowering stem with a very long rhizoid of U. ochrolenca , originating from the 
Konigsveen in Holland. R = rhizoid ; s = dissected subterranean shoot ; w = water-shoot ; F = 
flowering stem. 
Fig. 7. A lateral segment of the middle region of the same rhizoid ; it is repeatedly furcate and 
terminates in eight bent and papillous terminal segments, x 20. 
Fig. 8. A very little segment coming from the highest region of the rhizoid, and which terminates 
in three papillous segments, x 20. 
PLATE XLVIII. Figs. 9-19. 
Fig. 9-12. Flower-forms of U. ochroleuca. 
Fig. 9. Illustrates a flower, side-view ; the spur (j) is to be seen conspicuously ; the lower lip 
is rather flat, x 4. 
Fig. 10. Also illustrates a side-view; the lower lip is slightly curved in saddle-form, the spur 
therefore being covered, x 4. 
Fig. 11. A front-view of the flower; before the upper lip the globose palate is visible; the 
lower lip is rather flat, and below this the spur can be seen. x 4. 
Fig. 12. Gives a view of the flower from underneath. The spur appears as a prolongation of the 
upper lip and overlaps the entrance to the palate ; the two-lipped calyx is visible from below, x 4. 
In all figures k — calyx ; 0 = upper lip ; u = lower lip ; p = palate ; s = spur. 
Fig. 13-15. Flowers of U. intermedia . 
Fig. 13. Illustrates a lateral view of the flower. The lower lip is slightly curved in saddle-form 
and therefore covers the spur, the point of which, however, penetrates below. 
Fig. 14. Front side of the flower. Through the tender— and in consequence of the action of the 
alcohol — now transparent lower lip the spur can be faintly seen ; the palate is scalloped a little at 
the top ; the two anthers are visible in the form of two little dark spots. 
Fig. 15. Demonstrates a flower from below. The long spur appears also here as a continuation 
of the upper lip, and projects over the entrance to the palate ; the lower lip is slightly curved 
downwards. 
Figs. 13-15 are x 4. The flowers originate from W’allisellen near Zurich (Switzerland); 
k = calyx ; 0 = upper lip ; u — lower lip ; p = palate ; s — spur. 
Fig. 16. A leaf of U. ochroleuca, furnished with a bladder. From shallow water near Boat 
of Garten (Scotland), x 4. 
Fig. 17. A bladderless and very richly branched water-leaf of U. ochroleuca , originating from - 
shallow water. From the Loch nan Mathair Etive. x 4. 
Fig. 18. A leaf furnished with a bladder, originating from a floating form of deeper water. 
From the Loch nan Mathair Etive. x 4. 
Fig. 19. A water-leaf of U. intermedia bearing a bladder on the lower right side. From 
Norfolk (Honing, East Norfolk), x 4.
