date, petioles as long as the blades or much longer: scapes 
erect, 2-4 dm. tall: panicle narrow, 5-15 cm. long, the 
branches erect or nearly so: pedicels glandular-pilose : sepals 
2-2.5 mm. long, triangular-ovate, reflexed: corolla white ; 
petals oblong to oblong-lanceolate, 3-5 mm. long, sometimes 
slightly accrescent: filaments filiform, longer than the petals:

Related to Saxifraga punctata L.; but the leaves with 
blades manifestly longer than broad, the narrow panicle with 
its short branches and the lower leaf-like bracts, and the 
larger fruit are some of the characters which readily separate 
this species from its relative.
