 UTRICULARIA (continued). 



UtriaUaria montana Description of the bladders on the subterranean 

 rhizomes Prey captured by the bladders of plants under culture and 

 in a state of nature Absorption by the quadrifid processes and 

 glands Tubers serving as reservoirs for water Various other species 

 of Utricularia Polyiwmpholyx Genlisea, different nature of the 

 trap for capturing prey [Sarracenia] Diversified methods by which 

 plants are nourished. 



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 

 specimens 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 divid- 

 ed, as in the foregoing aquatic species. They are elongated, 

 about li inch in breadth, and furnished with a distinct foot- 

 stalk. The plant produces numerous colourless rhizomes,* 

 as thin as threads, which bear minute bladders, and occasion- 

 ally swell into tubers, as will hereafter be described. These 

 rhizomes appear exactly like roots, but occasionally throw up 

 green shoots. They penetrate the earth sometimes to the 

 depth of more than 2 inches: but when the plant grows as
