SHEVOCKIA (NECKERACEAE), A NEW MOSS GENUS WITH TWO SPECIES FROM SOUTHEAST ASIA

Abstract

  Shevockia Enroth & M.C. Ji gen. nov. (Neckeraceae, Bryopsida) is described from SE Asia. It has two species, S. inunctocarpa Enroth & M.C. Ji sp. nov. (generitype) from Yunnan Province of China, and S. anacamptolepis (Müll. Hal.) Enroth & M.C. Ji comb. nov., which has a wider distribution in Asia. Shevockia is morphologically close to Pinnatella, but differs especially in several gametophyte characters: 1) distinctly asymmetric leaves, 2) often undulate upper parts of stem leaves (less so in branch leaves), 3) relatively weak and short, sometimes bifurcate costa, and 4) presence of numerous large, leaf-like pseudoparaphyllia around the branch primordia. Shevockia inunctocarpa is illustrated by line drawings and a photograph.
