Funkiella
Funkiella hyemalis
Funkiella is a genus of the orchid family (Orchidaceae), which contains only four species. The outspoken alpine plants are spread from Mexico to Texas over Costa Rica.
Description
The species of the genus are terrestrial Funkiella growing, small, perennial, herbaceous plants. The roots arise in tufts at the base of the shoot, they are fleshy, hairy, bulbous thickened, sometimes stalked. A few sheets are available in a loose rosette together. They are narrow - ovate to lanceolate and end pointed, in some species they are clearly stalked. In its heyday, the leaves are sometimes already wilted.
The terminal, erect inflorescence is a wenigblütige, einseitswendige grape. The peduncle is smooth or at the top of glandular hairy. The bracts that surround the peduncle are tubular to lanceolate, they end pointed. The bracts are large, oval and pointed ending. The resupinierten, fragrant flowers are white or greenish, with red or red-brown drawing. The ovary is fusiform to cylindrical, glabrous or only slightly pubescent, scarcely twisted. While the ovary is upright, the tubular perianth sideways or slightly downward. The three sepals are unequal shaped, the dorsal sepal is partially fused with the column, the lateral sepals are enlarged at its base asymmetric and something that they form there with the slightly baggy base of the lip a blunt bulge. The petals adhere to the dorsal sepal. The lip is folded rinnig, the tip is bent downward. The lower half is fleshy at the base, with the lateral sepals and the extension of the column ( pillar ) a bag-like nectary forming there the edges are thickened to nectar glands. The column is slender club-shaped, with a short, curved foot. The scar is oval and is transverse to the column axis. The stamen is oval to heart-shaped and pointed, the column surrounds it with a thin tissue ( Klinandrium ), the filament is completely overgrown. The bright yellow pollinia are club-shaped and stick to a linear - oblong, gray viscid disc ( Viscidium ). The separation between scar tissue and stamen ( rostellum ) is flexible and very thin triangular, it ends almost filiform.
Occurrence
Funkiella is in the southern USA (Texas ), distributed in Mexico, Guatemala and Costa Rica. They occur at altitudes of 2,000 to 4,000 meters. The locations are forests of oak, pine and fir, dry scrub and alpine grasslands.
Systematics and botanical history
Funkiella is classified within the tribe Cranichideae in the subtribe Spiranthinae. The genus was described by Rudolf Schlechter in 1920 with the then single type Funkiella hyemalis.
While the genus Funkiella is already compared from Evil with Schiedeella, recent studies show a close relationship with the genus Microthelys.
The name Funkiella honors the Belgian plant collector Nicolas radio (also written Funck ).
