Annual herbs. Stems usually branched, dark purple, densely scabrous, up to 20 cm tall. Leaves aristate-acuminate at apices, slightly scabrous along margins; radical leaves lanceolate or ovate, 10-25 mm long, 4-7 mm wide; cauline leaves lanceolate to narrow-lanceolate, 6-13 mm long, 3-6 mm wide; sheaths about 2 mm long. Flowers pedicellate, solitary on terminal branches; pedicels 2-10 mm long; calyx-tube campanulate, 9-11 mm long, with 5 scabrous costae, 5-lobed, the lobes unequal in size, especially on buds, ovate to narrow ovate, aristate-acuminate at apex, 5-7 mm long, about 3 mm wide, the lobes with erose costae, minute aculeus along margins; corolla tubular-campanulate, yellow, with dark brown or black spots in the middle, 20-28 mm long, with 5 lobes; the lobes acutely ovate, 5 mm long, aristate-acuminate at apices, sinuses plicate with ovate-triangular appendages, appendages acute or cuspidate near apices; stamens 5, the anthers narrow, 2.5-3 mm long, the filaments about 18 mm long, attached slightly above the lower-part of corolla-tube; ovary shortly stipitate, lanceolate to narrow ovate, 12-14 mm long, 4-6 mm wide, stipe 2-3 mm long, style 6-7 mm long, the stigma bifurcate and spirally recurved at bloom. Capsules obovoid, about 9 mm long, 6 mm wide, stipe 18-20 mm long, 2-valved, dehiscent, the valves denticulate near upper-part.

Distribution and habitat. Endemic to Taiwan, in the northern and central parts of the Central Mountain Range from 2,600 to 3500 m in elevation. Commonly found on exposed rocky slope and mixed with grassland. Flowering and fruiting Jul-Nov.

Notes. Ying (1978) described this taxon distinct from G. scabrida based on pale flowers with a densely black punctuated base. From the examination of holotype specimen, bigger flower and wider calyx-lobe are equally useful characters for classification.
