Qiongzhuea

Small and medium-sized bamboos. an underground stem Compound axis hybrid type. The pole is upright; The internodes are cylindrical or the number of base nodes is slightly square, the internodes on the side with branches are slightly flat, often with 2 longitudinal ridges and 3 grooves, glabrous or sometimes slightly hairy, and the internodes at the lower part of the pole are solid or nearly solid; The rod ring is not uplifted or even extremely uplifted, but presents a round ridge, and there is a ring mark at the ridge, which is easy to break from the ring mark. There are 3 buds in each section of the culm, and the buds are elongated after the sheath is removed. At this time, they do not cling to the culm or cling to the culm; Each node of the pole is often divided into three branches, or sometimes it becomes many branches later, which can be lifted obliquely or even spread, and can be branched again, with slender twigs. Sheath sheath caducous, sparsely persistent, thick papery; Sheath auricle absent; Sheath segments degenerated, not more than 1 cm long. Leaf blade lanceolate to narrow lanceolate, small Transverse vein Clear. The flower branches can branch again and again to form a panicle "inflorescence". If they are born in the upper nodes with leafy branches, the flower branches are often no longer branched, and branches at all levels are often mixed with pseudospikelets on the same node; At the base of the last flower branch, there is a group of upward gradually increasing bracts. Pseudospikelets are sessile (the terminal ones seem to have stalks), with a first leaf and (0 -) 2-5 bracts at the base, and 1-3 bracts above have buds or secondary pseudospikelets in the axils. The base of the last secondary pseudospikelets usually has only one first leaf but no Bract 。 Spikelets contain 3-8 florets, slightly flat on both sides; Green or dark green; spikelet The axis is disjointed above the glume and between the florets. Its internodes are flat, glabrous, and the base is slightly white powder; Glume (1) 2 or 3 pieces; Lemma apex acuminate or long acuminate, glabrous, 7-9-veined; Palea usually shorter than its lemma, apex obtuse or slightly 2-lobed, back with 2 ridges; The integument is 3, the posterior one is narrower, the lateral two are wider; Stamens 3, anthers yellow to purple; Ovary obovate or elliptic, glabrous, style 1, stigma 2. The fruit is nut Shape, thick pericarp, leathery.^[1-2]

Qiongzhu (5 sheets)

Mode: Qiongzhu Qiongzhuea tunidinoda Hsueh et Yi is native to Sichuan.

The structure of flowers and fruits of Qiongzhu is similar to that of chimonobambusa Chimonobambusa Makino， However, this genus does not have spiny aerial roots at several nodes at the base of the stem, and usually shoots in spring. After being shelled, the shoots are clean white, not blackened by enzymes. It is a natural taxon different from the Phyllostachys. In terms of distribution, the altitude of Qiongzhu is located in the upper part of the Phyllostachys, which is more suitable for the cold environment. This genus may be more evolved than Phyllostachys.^[1]
