PRACTICAL GUIDE TO GABDEN PLANTS pinguicula 



salver-shaped, in spikes 6-10 in. long, 

 usually with several shorter ones from 

 the axils. 



Culture dtc. as above. This likes a 

 rather rich light soil and may be increased 

 by division or seeds. 



LXXXII. LENTIBULARIEiE— Butterwort Order 



A small order of aquatic and marsh-loving herbs, with radical or whorled 

 leaves in rosettes, entire or deeply cut, often bladder-like, Scapes erect, 

 1-flowered, or spicate or racemose. Flowers hermaphrodite, irregular. 

 Calyx inferior, 2-5-parted, persistent, 2-lipped or regularly 5-toothed. Corolla 

 gamopetalous, 2-lipped. Stamens 2, attached to the base of the coroUa, 

 or hypogynous. Ovary superior. Capsule 1-celled with numerous minute 



To this order belong the Bladderworts (TJtricularia), some of which are 

 remarkable for their floating leaves furnished with small pitchers and trap- 

 doors, which serve the purpose of ensnaring animalculae. 



PINGUICULA (Buttbrwoet).— An 

 interesting genus containing about 30 

 species of terrestrial marsh-loving herbs, 

 with radical leaves in rosettes, entire, 

 often greasy to the touch, and having the 

 peculiarity of imprisoning small insects 

 by means of the edges curling over when 

 irritated. Scapes erect, 1-flowered, with- 

 out leaves or bracts. Calyx 4-5-parted 

 or 2-lipped, the upper lip 3-parted, the 

 lower one 2-cleft or parted. Corolla 

 purple, violet, or yellow, 2-lipped, with 

 spreading entire or shghtly notched lobes, 

 the 2 upper ones equal or much shorter 

 than the other. 



Culture and Propagation. — The 

 hardy species described below all like 

 marshy or boggy places, and are suitable 

 for such situations in the rock garden. 

 When they flourish they look very pretty 

 and interesting, especially when several 

 are grown together. They may be in- 

 creased by seeds sown in peaty soil in 

 pots steeped half way up in water; by 

 dividing the crowns carefully in spring ; 

 or by putting detached leaves into sandy 

 and moist peaty soil under bell-glasses. 



P. alpina {Scottish Butterwort). — A 

 pretty little Scottish species about 3 in. 

 high, with elliptic oblong leaves about 

 ■§ in. long, somewhat hairy on the upper 

 surface. Flowers in May and June, 

 about i in. across, white, with a hairy 

 yellow throat, and a very short conical 

 spur. 



Culture So. as above. Flourishes in 

 a peaty gritty soil in boggy parts of the 

 rockery facing north. 



P. grandiflora (Irish Butterwort), — ^A 

 fine plant found wild in the bogs of Cork 

 and Kerry, with rosettes of pale green 

 fleshy, bluntly oval or oblong leaves 1-3 

 in. long. Flowers from May to July, 

 1 in. long and across, violet-blue, with a 

 straight or curved spur, and borne on 

 scapes 3-6 in. high. 



Culture dc. as above. This species 

 is perhaps the best of all Butterworts. 

 It flourishes in moist half-shady spots 

 in the rockery or bog garden in rich 

 fat loam that wiU not hold stagnant 

 moisture. The variety longifoUa from 

 the Pyrenees is very ornamental with 

 leaves 4-5 in. long, yellow-green and 

 clammy. It seeds freely. 



P. hirtiflora. — A native of the moun- 

 tains of Italy and Greece. It closely re- 

 sembles P. vulgaris, but has paler violet 

 flowers with a yellowish throat, and hairy 

 scapes and calyx. 



Culture dc. as above. It likes a rather 

 warm sunny position in the rookery in 

 moist peaty soil. 



P. lusitanica. — A native of the British 

 Islands and S.W. Europe, with oblong 

 shortly stalked thin fleshy leaves i-^ in. 

 long. Flowers from June to October ^ 

 in. long, lilac with a yellow throat, and 

 a short conical incurved spm-, on very 

 slender scapes about 6 in. high. 



Culture dc. as above. Peaty moist 

 soil in sunny places. 



P. lutea. — A N. American species about 

 8 in. high, with obovate-elliptic leaves 

 about 1 in. long. Flowers in siunmer
