96 THE FLORA OF THE ALPS 



The pitcher-like bladders with which the leaves are pro- 

 vided capture water animalcules, which are then consumed 

 and digested as in a stomach. 



The four British species: — U. minor ^ L., flowers light 

 yellow, leaf-segments denticulate-spiny, spur of corolla 

 minute ; U. vulgaris^ L., flowers dark yellow, upper lip of 

 corolla about as long as palate, spur conical ; U. neglecta^ 

 Lehm., upper lip of corolla two or three times as long as 

 palate; and U. intermedia, Heyne, spur conical, acute, 

 bladders on separate branches ; also U. Breemii, Heer, 

 resembling minor, but lower lip of corolla flat ; all in 

 marshes and swamps. 



Order LXIV.— GLOBULARIACEiE. 



Flowers small, in dense terminal umbels, surrounded 

 by an involucre; calyx 5 -cleft; corolla 4-5 -cleft, obscurely 

 2-lipped; ovary i -celled with a single pendulous ovule. 

 A small order, belonging almost entirely to the extra- 

 tropical Eastern hemisphere. 



I. Globularia, L. 



Flowers in dense globular umbels, blue ; calyx 4-cleft, 

 with linear teeth ; stamens 4, nearly equal in length ; 

 stigma simple, capitate. Alpine. 



G. cordifolia, L. ; stem 1-2J in., leafless, with barren 

 prostrate leafy shoots, leaves small, obcordate, a very 

 csespitose plant ; alpine pastures, frequent. G. nudi- 

 caulis, L.; stem 2-6 in., nearly leafless, with no barren 

 shoots, leaves large, 3-4 in. long, obovate- lanceolate; 

 alpine pastures; Switzerland, Dauphiny, Pyrenees. G.
