Louseworts and Toad-Flaxes. 



(Pedicularis and Linaria.) 



The plants liere illustrated belong to 

 the faniily of the Figworts (Scrophulariaceae). 

 They bave a two-lipped corolla,. usually 2 

 long and 2 short staniens and a two-celled 

 seedvessel. 



The Louseworts (genus Pedicularis) aro 

 especially characterised by their finely dis- 

 sected leaves; peculiar to them is also the 

 asymmetry of their flower, the upper lip 

 being turned to the one side, the uuder lip 

 towards the other. All the species of this 

 genus are parasitic on the roots of other 

 meadow plauts; they develope on their own 

 roots sucking discs {Haiistoria) by means of 

 which they attach themselves to other roots. 



Fig. 1. Whoried Lousewort. Differing 

 from all other Louseworts by their stems 

 bearing 4 — 5 leaves in the same node which 

 thus form a whorl. 



In pastures of 1600—2900 m. (rarely al- 

 ready at 1100 m.) 



Fig. 2. Lousewort with foliated spike. 

 Flowers yellow, upper lip blunt, not length- 

 ened iuto a point (not furnished with a 

 beak) and with hairs exterioraly. A high 

 leafy herbaceous plant which bears sessile 

 leaves even in the flower spike. 



Wildheuplätze*), grassy precipices of 

 debris, belts of turf, from 1100—2200 m. 



Fig. 3. Tuberous Lousewort. Has yellow 

 flowers with a long-beaked upper lip and 

 a tuberous rhizome with thickened fibres. 



Alpine pastures, turf, from 1800—2700 m, 



Fig. 4. Beaked Lousewort. Has red flowers 

 with a long beak on the upper lip. Spike 

 Short with but few flowers; lobes of the 

 calyx uotehed. Pedicularis reeurtita which 

 has also red flowers has a blunt upper lip 

 and a richly flowered spike. 



Pastures, turf, 1800—3000 m. 



Fig. 5. Alpine Toad-Flax. Stern re- 

 clining, towards its end asceuding knee-like. 

 Flowers violet with a long spur containing 

 honey and with an orange spot which in- 

 dicates the way to the neetar to the insects ; 

 in a uniformaly coloured variety (v. con- 

 color) thia spot is absent. 



This is a pla!at thoroughly characteristic 

 of rocky döbris, espec. of the cretaceous 

 mouutains and often descends with the de- 

 tritus of the rivers down to the plains. — 

 1600—3300 m.
