Perennial herb, flowering and fruiting period from March to November, with rhizomes and seeds. Adult plants are usually nearly glabrous without litchi. Rhizomes are thick and dense, often covered with brown stipules. Leaves basal, present in rosettes, leaf blade triangular-ovate, triangular or axillary, with prominent auricular lobes on both sides of base, usually spreading, petioles narrowly winged, both surfaces generally glabrous, or pubescent, densely covered nipples above Small white spot, stipules 3/4 combined with petiole, lanceolate, sparsely fringed, sparsely margined. Pedicel weak, with 2 linear bracteoles at middle and upper part, bracts ovate-lanceolate, base appendage elongated, 2-3 mm long, distally denticulate shallow teeth, petals lilac, tubular, 2.5--3 mm long Ovary spherical, glabrous. Fruits oblong fruit oblong, 8-10 mm long, glabrous, seeds ovoid, 1-1.5 mm long, dark green. Biennial or perennial herb, bald net.
Roots vertical. Leaves clustered, triangular or subconodont, 2–6 cm long, 1–3 cm wide, apex blunt, base concentric, margin serrate.
The stipules merge with the petioles, and their separating parts are narrowly lanceolate, entire, or sparsely toothed. Scallops slightly longer than leaves, subtrace-branched bracteoles suborbicular to middle or middle; oblong or lanceolate; petals 5, bluish purple, medial two pairs of petals spatulate, apex and central violet cyan, base yellow-green , There is a purple-blue pattern, the lower one is slightly wider, with a saccate, pale green; stamens 5, introverted, no filaments, below two appendages with nectaries; pistil 1, ovary superior, oval, style Trumpet shaped. 3 cracks, the majority of seeds.
Herbs perennial, without stems above ground. Rhizomes vertical or oblique, thicker, 1-2 cm long, 2-8 mm thick, densely packed, usually covered by brown stipules. Leaves are basal, rosette-like; leaf blade triangular, triangular-ovate or serpentine, 1.5-7 cm long, 1-3.5 cm wide, at their widest at the base of the leaf, gradually narrowing centrally upward, apex acuminate or apex, base Wide heart-shaped, curved and wide in semi-circular shape, with well-developed lateral tabs, usually spreading, extending slightly below petiole into narrow wings, margins with serrate teeth, both surfaces usually glabrous, rarely with leaf veins below and leaf near base There are short hairs on the margins, dense papillary white spots above, but dark green on older leaves; petiole glabrous, 2-7 cm long; stipules 3/4 connate with petiole, separating part lanceolate Shape, 3-5 mm long, apex acuminate, margin sparsely fimbriate, short teeth, sparsely entire, usually with brown rust. Flowers lavender, with dark stripes; pedicels weak, usually as long as or slightly taller than leaves, leafless, glabrous or upper pilose, with 2 linear bracts slightly above middle; bracts ovate-lanceolate or Lanceolate, 4-7 mm long, apex acuminate, base appendage elongated, 2-3 mm long, distally denticulate shallowly toothed, narrowly rimmed, glabrous or ciliatis; petals oblong-obovate, 7-9 mm long, lateral petals inside the base with the hairs, the petals below the distance of 10-12 mm; from the tubular, 2.5-3 mm long, straight, the end blunt; the lower part of the stamens back horn, about 2.5 Millimeters, apical apex, base broad; ovary globose, glabrous, style cylindric, ca. 2 mm, base geniculate, apically flat, with broad rims on both sides, anteriorly conspicuously short, calyxed With a stigma hole opening upwards. Capsule oblong, 8-10 mm long, glabrous. Seeds ovoid, 1-1.5 mm long, 0.8 mm in diameter, dark green. Flower and fruit period from March to November. 2n=24.
