General Information


Epífitas o terrestres, pequeñas hasta grandes, rizoma corto o con menos frecuencia alargado y rastrero; tallos secundarios generalmente engrosados en pseudobulbos subgloboso-ovoides, oblongo-ovoides hasta cilíndricos, generalmente 1–3-foliados (raras veces 4-foliados) apicalmente, lateralmente revestidos con varias vainas imbricadas con limbos foliares. Hojas y limbos de las vainas generalmente bastante angostos, conduplicados. Inflorescencias racimos o raras veces panículas, erectas o encorvadas, paucifloras a multifloras, emergiendo de la base de los pseudobulbos o de las axilas de las hojas, las flores generalmente grandes y vistosas, las brácteas generalmente mucho más cortas que los ovarios pedicelados; sépalos libres y patentes, angostamente lanceolados a linear-lanceolados, angostamente acuminados hasta caudados, todos aproximadamente de igual longitud o los sépalos laterales mucho más largos que el dorsal; pétalos similares al sépalo dorsal o más pequeños que éste; labelo patente, simple o inconspicuamente 3-lobado, más corto que los sépalos, sésil, disco con 1 callo longitudinalmente 2-laminado, 2-carinado o surcado, a veces piloso o verrugoso-glanduloso; columna corta y erecta, sin alas ni pie, longitudinalmente acanalada en la cara anterior, clinandro con el borde más o menos truncado, antera terminal, operculada, incumbente, 1-locular o imperfectamente 2-locular, polinios 2, cartilaginosos. Cápsulas elipsoides, obovoides o cilíndricas.

Género neotropical con ca 35 especies distribuidas desde Estados Unidos (Florida) y México hasta Brasil, Perú y Bolivia; 3 especies en Nicaragua.

    Herbs, epiphytic, ± cespitose. Stems either reduced and covered with sheathing bracts or elongate with prominent, single-noded pseudobulb. Leaves 1(–2) per sympodium, from apex of pseudobulb, often with 1–3 short foliaceous bracts subtending single-noded pseudobulb; blade conduplicate, oblong-lanceolate, dorsiventrally flattened, margins entire. Inflorescences lateral, racemes; bracts narrowly triangular. Flowers: sepals and petals distinct and free, long, attenuate-caudate; lip unlobed; callus prominent, 2-lamellate; column without appendages, footless; stigmatic cavity ± round; rostellum not prominent. Fruits capsules.

    Erect, epiphytic herbs with short stems usually thickened into conspicuous pseudobulbs that are infrequently rudimentary and inconspicuous or rarely entirely absent, the 1-3 leaves at the apex enveloped in several foliaceous or papery bracts, the conduplicate leaf bases distichously imbricating and forming a broad or narrow fan. Inflorescences 1-2 erect or arching, few- to many-flowered racemes produced from the bases of the pseudobulbs or concurrently with the flush of new growth, or, if the plants are pseudobulbless, from the axils of the leaves. Flowers usually large and conspicuous, subtended by small and inconspicuous, or elongate spath- aceous bracts. Sepals free, spreading, narrowly acuminate or caudate, sometimes of about equal length but more frequently with the lateral sepals conspicuously longer. Petals subequal to the dorsal sepal or smaller. Lip entire or obscurely 3-lobed, spreading, shorter than the sepals, the base sessile and adnate to the base of the column, the disk usually bilamellate. Column short, erect, without wings or appendages, the clinandrium scarcely prominent, usually truncate. Anther terminal, operculate, incumbent, 1-celled or imperfectly 2-celled; pollinia 2, waxy.
