Monocots Cyperorchis Cymbidium subgenus Cyperorchis Chinese orchids natural hybrids

Abstract

This study illustrates and describes Cymbidium × fugongense, a natural hybrid of Cymbidium wenshanense and Cymbidium eburneum or Cymbidium maguanense, from Yunnan Province, China. Morphologically, it has white-pink sepals and petals; petals are mottled and contain purple-red patches at their centres. The midlobe of lip is purple-red, with occasionally purple-red mottling on the base and apex of side lobes. The column is purple-red and mottled ventrally. Molecular analysis of plastid DNA (matK and rbcL) sequence data confirmed the natural hybrid as related to C. wenshanense, whereas the nuclear (ITS) DNA clearly supported a relationship of this material to species of C. subgenus Cyperorchis.
