UTRICULARIA MONTANA. [Chap. XVIII. 



an epiphyte, they must creep amidst the mosses, roots, de- 

 cayed bark, tc., with which the trees of these countries are 

 thickly covered. 



As the bladders are attached to the rhizomes, they are 

 necessarily subterranean. They are produced in extraordi- 

 nary numbers. One of my plants, though young, must have 

 borne several hundreds; for a sin- 

 gle branch out of an entangled mass 

 had thirty-two, and another branch, 

 about 2 inches in length (but with 

 its end and one side branch broken 

 off), had seventy - three bladders.* 

 The bladders are compressed and 

 rounded, with the ventral surface, or 

 that between the summit of the long 

 delicate footstalk and valve, ex- 

 tremely short (Fig. 27). They are 

 colourless and almost as transparent 

 as glass, so that they appear smaller 

 than they really are, the largest be- 

 ing under the sV of an inch (1.27 

 mm.) in its longer diameter. They

with those on the surfaces of the blad-

 rhizomes, and even on the entire leaves, but they are rather 

 broader on the latter. Vessels, marked with parallel bars 

 instead of by a spiral line, run up the footstalks, and just 

 enter the bases of the bladders; but they do not bifurcate 

 and extend up the dorsal and ventral surfaces, as in the 

 previous species.

 ders. This fact clearly indicates 



that the bladders on the rhi- 

 zomes of the present and follow- 

 ing species are modified segments 

 of the leaf: and they are thus 

 brought Into accordance with the 

 bladders attached to the divided 

 and floating leaves of tbe aquatic 

 species.
