SAXIFRAGACEiE. 85 



SPECIES IL— CHRYSOSPLENIUM ALTERNIFOLIUM. 



lAnn. 



Plate DLXIV. 



Stem simple, erect, not rooting at the lower joints. Leaves 

 chiefly radical, those on the stem alternate ; radical and lower 

 stem-leaves roundish-reniform, deeply cordate at the base, deeply 

 crenate ; crenatures at the apex of the leaf very large, truncate, 

 those towards the base rounded; petioles exceeding the lamina; 

 upper stem-leaf truncate at the base, which is abruptly attenuated 

 into a petiole about the length of the lamina. 



In damp places in woods, by the sides of ditches and streams, 

 and on wet rocks. With the preceding species, but much less 

 frequent. 



England, Scotland, Ireland. Perennial. Spring. 



This species bears a superficial resemblance to C. oppositifolium, 

 being similar in size and colour, though the latter is generally 

 rather deeper. The stems, however, do not creep and branch above 

 ground as in that plant ; the radical leaves are on stalks 1 to 4 

 inches long, the lamina f to 2 inches across, deeply heart-shaped, 

 and much more deeply crenate ; stem-leaves rarely more than 2, 

 alternate. The bracts are shorter and broader, usually deeper 

 yellow within ; the flowers are very similar, but with the calyx- 

 segments broader and brighter yellow. The upper part of the 

 stem and bracts is glabrous, as in C. oppositifolium. 



Alternate-leaved Golden Saxifrage, 



French, Dorine cb Feuilks alternes. German, Wechselbldttriges Milzkraut. 



Sub-Order II.— PAENASSIE.^. 



Herbs without stipules. Calyx nearly free from the ovary. 

 Petals imbricated in the bud. Nectariferous scales opposite the 

 petals, divided at the apex into long gland-tipped segments resem- 

 bling a number of filaments. Stamens only slightly perigynous. 



GENUS 111—1? ARNASSIA. Toumef. 



Calyx of 5 persistent sepals, more or less united at the base, 

 and adhering to the ovary only at the very base. Petals 5, at 

 length deciduous, with simple veins, somewhat perigynous. Nec- 

 tariferous scales 5, opposite the petals, with 3 to 13 setae united 

 at the base ; the threads or divisions with glands at the apex.
