4. Sabbatia angustifdlia (Michx.) Britton. Stems erect, 1-4 dm. tall, with several 
opposite branches above or sometimes branched at the base : leaf-blades narrowly oblong to 
linear-lanceolate, or oblong-spatulate at the base of the stem, 1.2-3.5 em. long, acute or 
obtuse, sessile: calyx glabrous; lobes narrowly linear, 8-10 mm. long, often variable in 
length: corolla rose-colored ; lobes oblong to spatulate-oblong, often barely surpassing the 
calyx-lobes : style longer than the stigmas : capsules oval, 5-7 mm. long. [S. brachiata Ell. ]
