Species

Paphiopedilum subgenus Megastaminodium is a subgenus of the orchid genus Paphiopedilum . [1] It was erected to accommodate the single species Paphiopedilum canhii due to its distinct characteristics that made it unfit for the other subgenera. Its placement has since been backed by cytological, molecular and micromorphological evidence. [2]

Distribution

Plants from this subgenus are found in rocky limestone massifs situated in the Kasi district of Vientiane Province of central Laos and a second population 180 km NNW in North-Vietnam at the Laotian border. [3]

<span class="mw-page-title-main">Cypripedioideae</span> Subfamily of orchids

Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium. They are characterised by the slipper-shaped pouches of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily.
