Morphological characteristics

1. Two years before the car

Herbs or perennial herbs. Mostly rooted. Roots short, slightly thicker. Ye Jisheng is in the shape of a rosette, lying supine, obliquely or erectly; leaves thin papery or papery, broadly ovate to broadly elliptic, 4-12 cm long, 2.5-6.5 cm wide, apex obtuse to acute, margin undulate, Sawtooth, teeth or split teeth below entire center, base broadly cuneate or suborbicular, ± reduced in extension, sparsely pubescent on both surfaces; veins 5-7; petiole 2-15(-27) cm, base Expand into sheath, sparsely pubescent. Inflorescences 3-10, erect or bowing; peduncle 5-30 cm long, with vertical stripes, sparsely white pubescent; spikes terete, 3-40 cm long, dense or sparse, lower part often Intermittent; sepals narrowly ovate-triangular or triangular-lanceolate, 2-3 mm in length, long and broad, keelbroadly broad, glabrous or apically sparsely short-bred. Flowers shortly stalked; calyx long 2-3 mm, bracts obtuse or blunt at tip, keel extension without extension, anterior bracteoidal elliptic, keelbone wider, slightly asymmetrical on both sides, posteriorly bracteolate wide Elliptical or broadly obovate. Corolla white, glabrous, crown and bracts approximately equal in length, lobes narrowly triangular, ca. 1.5 mm, apex acuminate or cuspidate, with distinct midrib, reflexed after anthesis. Stamens were born on the inner surface of the crown near the base, with styles apparently extended, anthers ovate-elliptic, 1-1.2 mm long, apically with broad triangular projections, white, and pale brown after drying. Ovules 7-15 (-18). Capsule spindle-shaped, ovoid, or ovoid-ovate in shape, 3-4.5 mm long, cleft above base. Seeds 5-6(-12), ovate-elliptic or elliptic, long (1.2-)1.5-2 mm, angular, dark brown to black, dorsal-ventral; microveined; cotyledons abaxially arranged. Flowering from April to August, fruiting from June to September. [1]

2. The difference between the front of the cart and the front of the cart is that: the leaves are oval or broadly ovate, 6–10 cm long, 3–6 cm wide, rounded at the tip and rounded at the base; the base of the petioles is often enlarged or sheathed. Spike length 3 ~ 10cm, flowers arranged closely. 7 to 15 seeds, black.

3. The difference between the front and the front of the flat car is that the plants have cylindrical straight roots. Leaf blade elliptic, elliptic-shaped lanceolate or ovate-lanceolate, base narrow. The calyx lobes and sepals are about the same length. Capsule conical. Seeds oblong, brownish black.
