Lithophragma
''Lithophragma'' is a genus of flowering plants in the saxifrage family containing about nine species native to western North America. These plants are known generally as woodland stars. The petals of the flowers are usually bright white with deep, long lobes or teeth. Each petal may look like three to five petals, when at closer inspection the lobes fuse into a single petal at its base. Most species reproduce via bulblets instead of seeds. ''L. maximum'' is a federally listed endangered species. ''Lithophragma'' specifically coevolved with moths of the genus ''Greya'', who pollinate and only lay eggs on ''Lithophragma'' plants. Species There are 9 species. The Flora of North America North of Mexico counts 10 species, elevating ''L. parviflorum'' var. ''trifoliatum'' to species status, but the Jepson Manual considers it to be a variety of ''L. parviflorum'' restricted to California. *''Lithophragma affine'' - San Francisco woodland star *''Lithophragma bolanderi'' - Bolander' ...

Saxifrage Family
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus ''Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are herbaceous perennials (rarely annual or biennial), sometimes succulent or xerophytic, often with perennating rhizomes. The leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence stems. They are usually simple, rarely pinnately or palmately compound. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. The inflorescences are br ...
