Fig. 1. Saxifrage fausse androsace. Feuil- 

 les temlres, allongees eu forme de laague; 

 petales d'ua blaae laiteux deux fois plus 

 longs que le calice. 



Lieux humides, de 1700 ä 3000 m. 



Fig. 2. Saxifrage variable. Petites feuilles 

 radicales generalement palmisequecs, k 3 ou 

 5 lobes, Sans sillons, rarement toutes en- 

 tiferes. Petales verdätres, d'un rouge-orauge 

 chez une variete. Tige portant de 1 a 10 

 fleurs. 



Rochers, gazons, de 1600 ä 4000 m. 



Fig. 3. Saxifrage ä feuilles rondes. Plante 

 elevee ä feuilles radicales cordiformes ou 

 r^nifoi-mes. Petales blaues ponctues de 

 jaune et de rouge, inflorescence en pani- 

 cule lache. 



Lieux humides, ombrages, surtout daus 

 les forets, de 800 ä plus de 2000 m. 



Fig. 4. Saxifrage ciliee. Feuilles ciliees 

 au bord de poils raldes (comme dans la Saxi- 

 frage mousse (planche 12, fig. 1). Les touffes 

 sont toutefois moins serrees et les bourgeons 

 axillaires arrivenr seulement ä la moitie de 

 la feuille qui les protege. 



Rochers humides, au bord des ruisseaux, 

 rarement dans les päturages, de 1400 h 

 3000 m. 



Fig. 5. Saxifrage de Seguier. Voisiue de 

 la Saxifrage fausse androsace, mais les feuil- 

 les sont obtuses et les petales jaunes de- 

 passent de peu les dents du calice (ce qui 

 est mal representö dans le dessin). 



Eboulis, rochers, de 2700 ä 3000 m. 



Fig. 6. Saxifrage ä feuilles opposeas. Ca- 

 ract^risee par ses feuilles opposees et im- 

 briquees et par sa corolle d'un rouge vineux. 



Eboulis, rochers, gazons, de 1500 k 3300 m.

 Saxifrages (continuation). 



SaxitVag-a. 



Fig. 1. Androsace-lii<e Saxifrage. Leaves 

 soft, tongueshaped. Petals of a milky white, 

 double as long as the calyx. 



On damp places, from 1700—3000 m. 



Fig. 2. Changeable Saxifrage. The leaves 

 of the rosettes aremostly split in 3—5 sections, 

 they are all undivided; petals greenish, in 

 a variety of an orange red; i— 10 flowers 

 on each stalk. Very variable! 



Fissures in the rocks, belts of turf, 

 more rarely on pastures and on beds of 

 mould, from 1600—4000 m. 



Fig. 3. Round-Ieaved Saxifrage. A high 

 herbaceous plant with longstalked, heart-or 

 reniform radical leaves ; petals with yellow 

 and red dots. Inflorescense a loose paniele. 



On damp, shady places, especially in 

 mountain and Alpine woods, from 800 to 

 over 2000 m. 



Fig. 4. Stiffhaired Saxifrage. Leaves ci- 

 liated on their margins with stitf hairs as 

 in Mosslike Saxifrage (plate 12, tig. 1), but 

 the plant is in loose plots and the buds in 

 the axles of the leaves are only half as long 

 as the leaf that bears them. 



Damp rocks, Ijanks of streams, more 

 rarely in the turf, from 1400—3000 m. 



Fig. 5. Seguier's Saxifrage. Resembling 

 the Saxifraga androsacea but with blunt 

 leaves and yellow petals which are only a 

 little longer than the lobes of the calyx 

 (not well given in the plate). 



Rock debris, fissures in the rocks, from 

 2700—3000 m. 



Fig. 6. Purple Saxifrage. This belongs 

 to a particularly charaeteristic group of 

 Saxifrages which is marked by the thiekly 

 placed, imbricated, opposite, thickish, blue- 

 green leaves and the wine-red flowers. This 

 species has singly placed flowers and simple 

 hairs on the margin of the lobes of the ca- 

 lyx. All the other species which could be 

 confounded Avith it, have glandulär hairs 

 terminated by a globular head on the mar- 

 gins of the calyx. (Saxifraga Rudolphiana 

 has also singly placed flowers, Saxifraga 

 biflora and Saxifraga Kochii a 1—5 flowered 

 stalk.) 



On rock debris, fissures in the rocks 

 and on belts of turf, from about 1500 to 

 3300 m.
