The flowers of Chrgsosplemi/ni 1 (figs. 365-367) are found on the 

 whole as in Saocifraga ; but they are apetalous, pentamerous or tetra- 

 merous, usually diplosteinonous, more rarely isostemonous. The

receptacle is obconical or urceolate, everted and of no great depth. 

 The one-celled ovary becomes a partly inferior polyspermous capsule, 

 dividing above into two equal or unequal lobes. Some fifteen species 2 

 are known, inhabiting the temperate and frigid regions of Europe, 

 Asia, and North and South America. They are little annual or 

 perennial herbs, with alternate or opposite exstipulate leaves, and little 

 greenish axillary and terminal flowers. 



Next to Saocifraga and Chrgsosplenium come several other herbaceous 

 genera, only differing in details ; Tellhna, Mile/la, 

 Heuchera, and Tiarella. In Tellima 3 (fig. 3GS) the Teliima grandijiora. 

 ovary is partly inferior and one-celled, with two 

 parietal placentas, a gamosepalous calyx with five 

 deep divisions, five entire or lobed petals, and five 

 or ten small included stamens, inserted on the 

 periphery of a disk. 4 It consists of some half- 

 dozen American species, herbs with alternate lobed 

 or dentate leaves and racemose 5 flowers."
