Diagnosis
Shoot phyllotaxy unknown, probably spreading. Leaf c. 1 mm wide, length unknown, probably 3–4 mm, outline lanceolate, bilaterally flattened, apex acute, base narrowed to false petiole, twisted. Margin prominently toothed, or teeth slightly set back from margin on nonstomatal surface, teeth formed by multicellular extension of lamina. Amphistomatic, stomates in single zone covering central half of leaf width, in 6 or 7 overlapping rows, loosely chained to isolated, oriented parallel to long axis of leaf, haplocheilic, amphicyclic, basically paratetracytic, but frequently with radial cell divisions which increase subsidiary cell number, polar cells projecting slightly from outline, subsidiary cells at same level as encircling cells, Florin rings distinct but subdued. Epidermal cells in files, rectangular to irregular, clearly visible on outer cuticular surface, glabrous.
