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

UTRICULARIA 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,

and furnished with a dis- 

 tinct footstalk. The plant produces numerous colour- 

 less rhizomes, as thin as threads, which bear minute 

 bladders, and occasionally swell into tubers, as will
