LATE LATE EARLY

Common Name Herzog's Myoxanthus [German Botanist 1880 to 1961]

Flower Size .2" [5 mm]

Found in Ecuador and Bolivia at elevations of 2600 to 3000 meters as a small to medium sized, cold growing caespitose epiphyte with erect, slender ramicauls enveloped by 5 to 8, long tubular, hipodous sheaths and carrying a single, apical, erect, coriaceous, very narrowly ovate, acute, cuneate below into the subpetiolate base leaf that blooms in the late winter, spring and early fall on a congested fascile, at the apex of the ramicaul, peduncle .04 to .12" [1 to 3 mm] long, simulateously few, single flowered inflorescence with infundibular, red-spiculateshorter than the ovary floral bracts with yellow green sepals lightly suffused with purple, fleshy, shortly pubescent externally, cellu;lar glandular within, light yellow petals and a yellow below the middle, dark purple above lip.

"This species is was first described by Schlechter from a Bolivian collection by Herzog. Because the location of the type was unknown and because Schlechterís illustration and description of P. herzogii could apply to M. ceratothallis, and because M. ceratothallis had been collected by us nearby in Bolivia, M. herzogii was erroneously listed as a synonym of M. ceratothallis in Systematics of Myoxanthus in 1992. An illustration of a hydrated flower from Herzog 2423 at Stockholm (S) reveals that it is conspecific with the recently described M. affinoides Luer from Ecuador. Only insignificant differences exist. Myoxanthus herzogii is distinguished by the slender ramicaul, a long, very narrowly ovate leaf, and a few-flowered fascicle of shortly pedunculate flowers. The sepals are fleshy, obtuse and densely short-pubescent externally. The petals are linear and thickened above the middle, and longer than the lateral sepals. The lateral lobes of the oblong lip are below the middle and antrorse with a low pair of carina on the disc between them." Luer 1994
