Utricularia montana — Description of the bladders on the subter- 

 ranean rhizomes — Prey captiu'ed by the bladders of plants under 

 culture and in a state of nature — Absorption by the quadrifid pro- 

 cesses and glands — Tubers serving as reservoirs for water — 

 Various other species of Utricularia — Polypompholyx — Genlisea, 

 different nature of the trap for capturing prey — Diversified 

 methods by which plants are nourished. 



Uteiculaeia MONTANA. — This species inhabits the 

 tropical parts of South America, and is said to be 

 epiphytic; but, judging from the state of the roots 

 (rhizomes) of some dried spe- 

 cimens from the herbarium 

 at Kew, it likewise lives in 

 earth, probably in crevices 

 of rocks. In English hot- 

 houses it is grown in peaty 

 soil. Lady Dorothy Nevill 

 was so kind as to give me 

 a fine plant, and I received 

 another from Dr. Hooker. 

 The leaves are entire, instead 

 of being much divided, as 

 in the foregoing aquatic 

 species. They are elongated, 

 about IJ inch in breadth, 

 and furnished with a dis- 

 tinct footstalk. The phint produces numerous colour- 

 less rhizomes, as thin as threads, which bear minute 

 bladders, and occasionally swell into tubers, as will
