Gynura cusimbua (scientific name: gynura cusimbua), also known as babbling vegetables, sunflower seeds, bean curd, and purple-angled leaves, is a tall perennial herb with a height of1.5-2m. The flowering and fruiting period is September 9- 10/October. Saxifraga is fed on seedlings, tender shoots or tender leaves, with soft and smooth texture and high nutritional value. Can be used as soup, stir-fry, hot food, cold salad, etc., its taste is fragrant, and it is as crisp and refreshing as eating fungus when chewing, so it is named auricularia auricula. It is widely cultivated in the north and south, perennial in the tropical region of the south and annual in the north.
morphological character
Saxifraga (***5 pieces) is a tall perennial herb with a height of1.5-2m. The stem is fleshy, woody at the base, with a diameter of1.5-2cm, the lower part is recumbent, the upper part is upright, with many umbrella-shaped branches, green or purplish, obvious grooves, no hair or some hairs on the upper part.
Leaves are large, sessile or short-stalked; Leaf blade obovate, oblong-elliptic, elliptic or oblong-lanceolate, length10-30cm, width 4-1cm, tapering at the top, broad auricle with short stalk or sessile at the base, irregular sharp serrations at the edge, small tips at the tooth ends, and lateral veins/. The upper leaves are tapered, oblong-lanceolate or lanceolate, and the top end is tapered or caudal.
The diameter of the head is 10- 12 mm, usually 4- 15 flower stems, and the branches are arranged in corymbose panicles; Inflorescence branches are unequal in length, peduncle is thin, long 1.5-3 cm, in 2-3 filiform linear bracts, pubescent.
The involucral bracts are narrowly bell-shaped or cylindrical, with a length of 12- 17 mm and a width of 8- 12 mm, and there are 7-9 linear bracteoles at the base; Involucre 1 layer, 13- 15, linear or linear-lanceolate, length 13- 15 mm, width 1- 1.5 mm, and gradually tapering at the top. There are about 50 florets, orange yellow, corolla length113mm, thin tube, 7-9mm long, enlarged upper part, triangular ovate lobes and 3-4mm long eaves.
Achene is cylindrical, 4-4.5 mm long, brown, with 10 ribs, with hairs between ribs. Most crown hairs are white, silky, long 10- 15 mm, and easy to fall off. The flowering and fruiting period is September 9- 10/October. [ 1]
