Herbs, annual. Stems erect, 12-45 cm tall, branched from base or middle, sparsely arachnoid to glabrous. Leaves sessile; blade oblanceolate-spatulate or oblong, 3-11 × 0.5-2 cm, ± arachnoid especially abaxially, to glabrous, shallowly to deeply pinnatifid with 6-8 oblong or oblong-lanceolate, usually irregularly dentate lateral lobes, lower ones attenuate into a petioloid base, middle ones subamplexicaul, apex obtuse; upper leaves smaller.
