Descriptions
Zoysia planifolia Zotov
Plant perennial. Rhizome internodes mostly in series of three — 2 very short and 1 long — the three internodes 1-2 cm long. Cataphylls truncate, lingulate, almost quite bladeless. Erect culms arise from one or both short internodes, 8-15 cm high above ground, branching several times at and above ground. Branching intravaginal; 2-3 internodes elongated, uppermost 4-7 cm long. Leaf sheath 1-3 cm long, glabrous finely striated. Ligule a line of hairs 0.3-0.5 mm long. Leaf collar distinct, more or less densely long-ciliate, hairs soft, cushion-based. Blade more or less distinctly divergent rolled in bud, flat at maturity, up to 5 cm long 2-3 mm wide, tapering, finely striate on both sides, glabrous. Vascular bundles about 25. Sclerenchyma bilateral, interrupted between vascular bundles, connected with primary bundles, more or less free from secondary bundles. Peduncle 4-7 cm long, glabrous. Racemes 8-16 mm long, of 6-12 appressed spikelets. Rachis and pedicels minutely scabrid. Pedicels 0.5-1 mm long. Spikelets about 4 mm long, lanceolate. Glume 4 mm long, ovate, indurated with thin margins, minutely hairy above and on margins, stramineous, about 7-nerved, nerves very weak. Lemma about 3.5 mm long, ovate-lanceolate, more or less conduplicate, 1-nerved, firm, hyaline, glabrous. Anthers about 2 mm long. Stigmas long, plumose (Fig. 1).
Planta perennis. Rhizomatis internodia persaepe in tripartita serie disposita — duo brevissirna, unum longum — haec tria internodia 1 - 2 cm longa. Internodium longius longiore cataphyllo est subtentum. Cataphylla truncata, lingulata, paene omnino laminis carentia. Culmi erecti, 8 - 1 5 cm alti, oriuntur ex axillis brevium cataphyllorum vel unius vel amborum, aliquoties ramos emittentes ad soli superficiem vel supra. Ramificatio intravaginalis; 2 - 3 internodia elongata, supremum 4 - 7 cm longum. Folii vagina 1 - 3 cm longa, glabra, subtiliter striata. Ligula ciliaris, 0.3 - 0.5 mm longa. Folii collum distinctum plus minusve dense longeciliatum, pilis mollibus basi pulviniformibus. Lamina plus minusve distincte divergens, in gemma involuta, ad maturitatem plana, ad 5 cm longa, 2 - 3 mm lata angustata, in utraque facie subtiliter striata, glabra. Fasciculi vasculares circa 25. Sclerenchyma bilaterale, inter fasciculos vasculares interruptum conjunctum cum fasciculis primariis, ab fasciculis secundariis plus minusve disjunctum. Pedunculus 3 - 7 cm longus, glaber. Racemi 8 - 1 6 mm longi ex 6 - 12 spiculis appressis constantes. Rhachis pedicellique minute scabridi. Pedicelli 0.5 - 1 mm longi. Spiculae circa 4 cm longae, lanceolatae. Gluma 4 mm longa, oyata, indurata, marginibus tenuibus, minute pilosa supra et in marginibus, straminea, circa 7-nervis; nervi obscurissimi. Lemma circa 3 - 5 mm longum, ovato-Ianceolatum, plus minusve conduplicatum, 1-nerve, firmum, hyalinum, glabrum. Antherae ciica 2 mm longae. Stigmata longa, plumosa.
