A new species of Dichromanthus (Orchidaceae, Spiranthinae) from Oaxaca, Mexico
Dichromanthus yucundaa, a new orchid species from the Mixteca Alta region of the Sierra Madre del Sur in Oaxaca, Mexico, is described and illustrated. It is distinguished from D. cinnabarinus, the most similar species, by the more compact plants, glabrous inflorescence, prominent, broadly ovate, glabrous floral bracts which are abaxially glaucous, sparsely and minutely glandular-pubescent sepals (merely papillose near the apex), short column foot, viscidium sheathing the apex of the rostellum and without a retrorse prominence, and rostellum remnant stiff and pointed.
