Crowfoots and Grass of Par- 



nassus. 



Genera Ranunculns & Parnassia. 

 The family of the Crowfoot-plants is 

 marked by the following general character- 

 istics of its members: the sap is acrid, 

 ofton even poisonous; they form therefore 

 bad herbage for fodder. The flowers have 

 numerous stamens having their Insertion on 

 the axis of the flower not on the calyx (dif- 

 ference from the Roseworts); the stempeis 

 are also numerous and separate, forming in 

 the middle of the flower a small green knob . 

 Fig. 1. Glacier Crowfoot. Calyx with 

 thick tufts of reddishbrown-blackish hairs; 

 corolla white or red especially on the outer 

 side. Plant smooth or eovered with cob- 

 web-like hairs. 



Stony debris, fissures in the rocks, turfy 

 places on the highest aretes and summits, 

 from about 2300—4270 m.; they are the 

 highest mounting flowering plants of Switzer- 

 land. They have been found tili within a 

 Short distance from the summit of the Finster- 

 aarhorn. 



Fig. 2. Alpine Crowfoot. Plant qulte 

 bare, low; stem 1—3 flowered, 5—10 cm. 

 high ; leaves glossy, on the upper side with 

 furrowlike sunken nerves. Leaves of the 

 stalk undivided. 



On the margin of melting snow fields, 

 on rather damp pastures, in snow hollows, 

 on glacier soll, on dripping rocks, common, 

 from 1500—2600 m. 



Fig. 3, 4, 5. Aconite-Ieaved Crowfoot. A 

 plant of 30—90 cm. in hight, with branehed 

 many flowered stem and with palmated root- 

 and stemleaves. 



Damp swampy meadows, brookbanl<s 

 „Läger" etc., from the hill country up to 

 2200 m.

 Fig. 4. Whole plant reduced. 

 Fig. 5. Fruits in life size. 

 Fig. 6. Pyreneen Crowfoot. — Easily 

 known from other white flowering Crowfoot- 

 species by its grasslike, narrow, rather 

 blueish-green leaves; calyx bare. 



On damp meadows, often in great nura- 

 bers, from 1800—2700 m. 



Fig. 7. Parnassia-Ieaved Crowfoot, Ra- 

 dical leaves cordate-eggshaped, with strong 

 nerves, which are hairy on the upper side, 

 blueish-green ; calyx andflowerstalks woolly. 

 Rocky debris, moraines etc., rare, from 

 2300—2900 m. 



Fig. 8. Grass of Parnassus. Does not 

 belong to the family of the Ranunculaceae, 

 but to that of the Sundew plants. It is at 

 once known by its sessile heartshaped 

 stalkleaf. 



Swampy meadows, pastures, turf, from 

 the plains up to 2640 m. In the piain a true 

 marsh plant, in the humide Alpine climate 

 also in drv places. Ii is one of the few 

 species, whose flowers become smaller in 

 the Alps.
