Hubei shellfish, herbaceous plant. The plant is 26–50 cm long and 1.5–4 cm thick bulbs, consisting of 2–3 hypertrophic scales.
The stems of Hubei mussels are 30-90 cm tall and have leaves above the base.
Hubei shellfish leaves are lanceolate to strip-shaped, 6-15 cm long and 5-15 mm wide, the lower leaves are wide, the upper part is narrow and the apex tendrils are shaped, the lowest 2 leaves are opposite, and the remaining 3-5 are alternate or 2 are alternate. The middle is often both paraphyletic or scattered, rectangular lanceolate, 7-13 cm long and 1-3 cm wide, with no curling or much curvature at the apex.
Hubei shellfish flowers 1-4 flowers, purple and white flowers, with yellow small squares; Several flowers form a total inflorescence, rare as a single flower, apical flowers with 3-4 rotational bracts, and lateral flowers with 2 bracts; The bracts are leafy, striped, and the apex is curled; The flowers are drooping, judium-shaped; The flower is 6, matrix circular oval, 2-4 cm long, 1-1.5 cm wide, pale yellow or yellowish green, purple checkered pattern on the inner mask, dense spider above the base; The stamens are about half the length of the tecton, the anthers are nearly basal, and the filaments are often slightly small papillae; The peduncle is slightly longer than the ovary, along with the ovary slightly longer than the stamens; The stigma head is 3 lobes, and the lobes are about 2 mm long. The peduncle is 1-2 cm long; The trecosper is 4.2–4.5 cm long and 1.5–1.8 cm wide, with slightly narrower outer discs; The honey glandular fossa protrudes slightly on the back.
The hubei shellfish capsule is 2-2.5 cm long and 2.5-3 cm wide, and the wings on the edges are 4-7 mm wide. The capsule has broad wings.
Hubei shellfish and Tianmu shellfish are very close, the difference is that the leaf-like bracts of this species are curled at the apex, the peduncle is 1-2 cm long, and the leaves are usually 3-7 rotational.
Hubei motherfish mainly reproduces bulbs, but can also be propagated by scales and seeds. Bulb propagation: after the plant withers, the bulbs are dug up and planted after harvesting the enemy, from late May to early June; The stems are graded according to size and stored in saprophyll soil or wet sand for summer, and must not be planted later than mid-September. On the well-prepared furrow, the furrow is opened, about 10 cm deep, according to the size of the seed stem, the row spacing is 10-13 cm, the plant spacing is 3-7 cm, the seed stem is small and densely planted, the seed stem is large and thin, and the soil cover is flush with the furrow surface after planting, and the seed stem is 3000-4500kg per 1 hm2. Seed propagation: After multiple generations of asexual reproduction, 1 sexual reproduction should be carried out. However, due to the large number of flowering and the results of the plate shellfish, it is difficult to receive more seeds, and the seed propagation is still in the experimental stage.
Hubei shellfish focus on shading summer and weeding and fertilizing. In summer and autumn, there must be shade on the furrow, which must not be ignored. Autumn planting should also be based on climatic conditions, the necessary shade measures should be taken. During the growth period, attention should be paid to the timely removal of cover grass, and the weeding of medium cultivation requires shallow hoeing. After emergence and after flowering, it is necessary to properly topdress the fertilizer.
Hubei shellfish medicinal parts: bulbs, washed, dried. In the summer after planting in the 2nd year after the stem and leaf wilt can be harvested, dig up the bulbs, in addition to the seeds, should be processed in time, remove the soil, remove the stems and leaves, whisker roots, first with sulfur fumigation, generally fumigated for 10h, if the section turns white, then smoked thoroughly, smoked sulfur after sun drying or kang drying, into the sack to knock off the skin, sift off the sediment, and then washed with alum water, after drying.
Identification of Hubei shellfish drug traits The bulb is flattened or conical, 1-3.5 cm in diameter, 1-2 cm in height, pale yellow or yellowish brown on the surface, slightly rough, sometimes visible yellow-brown spots or plaques, 2 outer scale leaves, usually 1 smaller, hugged in a small number of 1 large scale leaf 2 pieces of equal size, the apex is flat, there are 2-3 small scales in the center and a dry and shrunken stump. Slightly bitter taste. Microscopic identification Powder characteristics: white. (1) Starch grains are mostly broadly oval, slightly flattened, a few kinds of round, diameter 4-25 (-45 μm), umbilical point short crack or point,occasionally three-pronged, visible layers. (2) The stomatals are flat and round, with a diameter of 40-65 μm, and a small number of paragua cells are 5. (3) Calcium oxalate crystals are square or cluster-like, with a diameter of 5-48 μm.
Hubei Beimu is distributed in Hubei (southwest), Sichuan (east) and Hunan (northwest). It is cultivated in the Area of Badong Wulong Creek and Xuan'en in Enshi Prefecture.
