WEAKLEY FLORA

SCIENTIFIC NAME: Lupinus diffusus
COMMON NAME: Blue Sandhill Lupine
SYNONYMY: [< L. diffusus - I, K1, K2, RAB, S, SE, WH3]
PHENOLOGY: Mar-May; Jun-Jul.
HABITAT: Sandhills, sandy roadsides.
COMMENTS: Se. NC south to s. FL, west to s. MS. I concur with Duncan & McCartney (1992) in recognizing L. cumulicola Small of peninsular FL as distinct from L. diffusus. Moreover, Atchison et al. (2014) show that at least an additional taxon (here listed as Lupinus species 1) should be segregated from L. diffusus s.l.
