Urricunaria (continued). 
Utricularia montana — Description of the bladders on the subter- 
ranean rhizomes— Prey captured 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. 
UrricuLaRIA MONTANA.—This species inhabits the 
tropical parts of South America, and is said to be

(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

species. They are elongated, (Utricularia montana.) 
about 13 inch in breadth, prmehes bearing minute bladuers sof

bladders, and occasionally swell into tubers, as will
