ABSTRACT
As weed in fields, along roadsides. West. Sib.: OM (Omsk town).—Europe, Mediterranean. Described from Europe.
2. L. orientalis L. 1753, Sp. PL: 139. Annual setaceous up to 50 cm tall plant. Stems erect, strong, generally
branches bifurcated in upper part, with stiff bristles but much shorter and compact than in the preceding species. Leaves thin, green, lanceolate, 3-9 cm long, 1-2.5 cm broad, almost invariably smooth-edged, but could be dentate, with compact stiff bristles. Lower leaves narrow toward base; upper leaves sessile, semiamplexicaul. Whorls rather few-flowered, more or less lax, elongating in fruit; leafy bracts lanceolate or linear-lanceolate, sharp, as long as flowers, ciliate along margin. Fruit stems much longer than in the preceding species, bristly. Calyx incised almost up to base into lanceolate-linear lobes with long bristles along margin, stellately procumbent in fruits. Corolla light
blue; tube bent below middle; limb about 5 mm in diam., more regular than in L. arvensis L.; arches large, crinite on throat; anthers tiny, about 1 mm long; style short, with tiny pitted stigma. Nutlets transverse-oval, longitudinally rugose and extremely fine-tuberculate, with thickened margin around the area of attachment.
