28o YELLOW TO ORANGE 



Potentillas and that of the Ranunculi have already been 

 referred to in the description of the latter plants, but it may 

 be further noted here that the stamens of the Ranunculi are 

 hypogynous, or borne at the base or below the ovary, while 

 those of the Potentillas are perigynous, or borne on the peri- 

 anth around the ovary. 



YELLOW SAXIFRAGE 



Saxifraga aizoides. Saxifrage Family 



Stems: leafy. Leaves: alternate, linear, thick, fleshy, mucronate- 

 tipped, narrowed at the base, sessile, the margins sparingly ciliate. 

 Flowers : several, corymbose ; petals five, oblong, yellow, usually spotted 

 with orange ; calyx five-lobed, base of the capsule adnate to the calyx ; 

 stamens ten, inserted with the petals. Fruit : ovary two-celled, two- 

 lobed at the summit ; styles short ; stigmas capitate. 



This Yellow Saxifrage grows among the wet rocks at very^ 

 high altitudes. It has slender stems, adorned with alternate 

 leaves, which are long and narrow and edged with a few fine 

 hairs. The flowers grow erect and open out very wide, their 

 petals being usually spotted with orange. The ten stamens are 

 conspicuous, and so is the large two-celled ovary, while the 

 styles are short and tipped with roundish stigmas. This plant 

 grows in dense tufted clusters from two to six inches high, and 

 may be found in the most sun-forsaken crannies, where the icy 

 breezes blow across the snow-fields. 



STONECROP 



Sediun steiiopetalmn. Orpine Family 



Flowering branches erect. Leaves: alternate, crowded, but scarcely 

 imbricated except on the sterile shoots, sessile, linear, entire. Flowers: 

 in a three-to-seven forked cyme, compact ; petals narrowly lanceolate, 

 very acute, much exceeding the calyx-lobes. 



This plant is well named Scdum, from sedcre "to sit," for 

 it sits very happily, and in lowly fashion, upon the bleak
