18 PINGUICULA. [class ii, order i. 



The whole plant larger, and of a stouter habit, than P. vulgaris ; 

 the leaves a much ligliter green, and more veiny. Scape from four to 

 nine inches high, supporting a single flower. Corolla rich purple 

 colour, larger, more equally divided and reticulated, with numerous 

 darker veins. The leaves are all radical, and, as well as the scape, 

 more or less covered with a glutinous exudation, but especially the 

 upper part of the latter. 



Habitat. — In elevated marshy ground, in the western part of the 

 county of Cork, and at Kenmare. 

 Perennial; flowering in May. 



The natural order Lentibularise of Richard is composed (Ti two small 

 genera of British plants — Pinguicula and Utricularia ; which are re- 

 markably beautiful water or bog plants. Pinguicula grandijlora and 

 vulgaris may be grown to a high state of perfection by cultivation, 

 especially the former, which is the largest and most beautiful of the 

 genera. This interesting species we have cultivated in various ways, 

 and under circumstances which warrant us in saying, that it is by no 

 means difficult of cultivation. It will grow, and rapidly propagate 

 itself, if planted in a moderately shady situation, in a mixture of equal 

 parts of loam, heath mould, and white sand ; during the time of flower- 

 ing, it should be freely supplied with water. If protected with a com- 

 mon garden-frame, the flowering season will be prolonged, and the 

 richness of colour and beauty of the flowers greatly increased. To- 

 wards autumn the leaves and roots gradually decay, and there are 

 formed small round leafy buds or hybernacula, about half an inch in 

 diameter, with several small ones attached to its base : each of which 

 being capable of forming new plants, may either be allowed to remain, 

 or be separated in the spring for the purpose of increase. The singular 

 change of this plant, from a tender and exceedingly succulent, folia- 

 ceous state, to a compact and comparatively hard leafy bud, is very 

 remarkable, and has evidently been so designed by Him who made all 

 things according to his own purpose, in order to its preservation during 

 the cold of winter ; for if a plant so delicate as this did not undergo 

 some change in order to its own preservation, or produce seed more 

 abundantly than it usually does, the probability is that it would soon 

 become extinct.

Leaves radical, ovate, obtuse, thick, fleshy, and glutinous, the margins 

 involute, covered with minute erect crystaline points, which are most 

 abundant on those plants grown in shady situations. Sva-pe from three 

 to nine inches long, single flowered. Corolla purple, its segments 

 unequal, entire; palate covered with white hairs; the spur sometimes
