cordate

Tree 10-15 m tall, small young branches yellowish gray to purplish brown, mature branches yellowish gray to yellowish brown, Stipule caduceus, linear lanceolate, apex acuminate, young petiole densely hairy, soon hairless; leaf blade ovate to broadly ovate, glabrous or thickly hairy when young, soon glabrescent, base rounded or sub-cordate or sometime cordate, lustrous green above, margin long spinulose serrate, apex shortly acuminate or long tapering acute apex.

The asymmetry of the young prothallus is only transitory, soon the meristematic region becomes apical, and a symmetrical cordate thallus is formed (Fig.

Qingfei Xieding prescription, a novel self-developed CTPM of our hospital, is a concentrated granule purified from herbs, including Ephedra sinica, apricot kernel, gesso, lobed kudzuvine root, Scutellaria baicalensis, Bombyx batryticatus, and Houttuynia cordate. The main ingredients of Qingfei Xieding are Houttuynia cordate and Scutellaria baicalensis, which exhibit multiple beneficial properties, such as antiviral, anti-inflammatory, antibacterial, antioxidant, antitussive, and immune-strengthening activities [12-14].

The vine variety has leaves that are green measured 4-5 cm wide and 9-10 cm long with acute tips and cordate to acute base.

2.5 cm diam., zygomorphic; sepals green, deltoid to elliptical or obovate to oblong, abaxial surface glabrous, 6-9.5 X 3-4.5 mm; petals yellow, two external, obovate, 7-9.5 X 4-5.5 mm, two internal, oblanceolate, 7.5-9 X 3.5-5 mm, cuculus cordate to orbicular, bent around the stamens, 11-13 X 6-7 mm; stamens yellow, 6-7.5 mm long; staminoids yellow, 3-5 mm long; ovary yellow, tomentose, 5-8 mm long; style green, 3-4 mm long.

Leaf is simple and petiolate, leaf blade is ovatetriangular, 2-8 cm long, and tip acuminate, leaf base is cordate or hastate, and upper leaves are small and sessile.

For leaf shape, ovate and cordate leaf shapes were observed in 38.3% and 35.1%, respectively.
