Habit | Rhizomatous perennials, occasionally rooting at nodes nearest base; stems 20-80 cm, prostrate or decumbent to ascending, only slightly branched, villous eglandular hairs 1-2 mm, occasionally with shorter stipitate-glandular hairs, internodes evident. | Annuals with fibrous roots or a filiform-taproot; stems usually 5-15 cm, erect to ascending, straight or sharply bent at nodes, usually unbranched, covered with stalked glands, gland-tipped hairs 0.2-0.5 mm. |
Leaves | Leaves cauline, basal ones not persistent, commonly congested; subsessile to sessile; blade oblong to lanceolate, 30-70 mm long and 10-22 mm broad, pinnate venation, base rounded, margins toothed to finely toothed, apex acute, surfaces hairy as stems. |
Leaves cauline, basal ones not persistent; petioles 8-25 mm; blade deltate or somewhat ovate to lanceolate, approximately 4-12 mm long and 3-10 mm broad, palmate venation with 3 veins, base rounded to cuneate-truncate, margins usually finely toothed, apex acute to obtuse, surfaces glabrous as stems. |
Flowers | Axillary flowers 4-10, emerging from nodes at mid- to ends of stems; fruiting pedicels generally 22-50 mm, hairy as stems; calyx winged, cylindric-campanulate, barely inflated, 10-12 mm, villous with gland-tipped hairs, lobes spreading noticeably, strongly unequal, linear-lanceolate to slender-triangular, 5-9 mm, apex long acuminate-apiculate; corollas yellow, throat faintly marked with blackish-brownish lines, symmetric almost radially or weakly bilaterally, nearly regular or weakly bilabiate; tube-throat slenderly bell-shaped, 15-18 mm, protruding beyond calyx margin; lobe apex rounded; styles glabrous; anthers not protruding, covered with fine hairs that are stiff to slightly rigid. |
Axillary flowers 1-10, emerging from nodes throughout; fruiting pedicels 10-25 mm, glandular as stems; calyx tubular, barely or not inflated, 5-6 mm, margins with distinct teeth or lobes, slightly stipitate-glandular to sparsely hirtellous, lobes pronounced, erect; corollas yellow, lower limb commonly with some red or brownish dots, symmetric radially or bilaterally, regular or weakly bilabiate; tube-throat funnel-shaped, 7-8 mm, protruding beyond calyx margin; lobes oblong, apex rounded to truncate; styles glabrous; anthers not protruding, glabrous. |
