Common Name The Heart-Shaped Cyrtochilum [refers to the lip]

Flower Size 2.2" [5.5 cm]

Found only in Peru in wet montane forests at elevations of 1500 to 2700 meters as a small to medium sized, cool to cold growing terrestrial on steep slopes covered with small trees, bushes and grass with narrowly ovate to conical pseuobulbs enveloped completely by several pairs of imbricate, leaf-bearing sheaths [these may be longer than the apical leaves] and carrying two, apical, elliptic-lanceolate, acute, conduplicate and narrowing below into the petiole-like base leaves that blooms in the fall on an axillary, twining, to 60" [150 cm] long, overall, paniculate, rachis to 15" [37.5 cm] long, with 2 to 6, lateral, 6" [25 cm] long branches 4 to 6 flowered each, that may have secondary branches, several to many flowered inflorescence carrying thin, waxy flowers.

CAUTION Not to be confused with Odontoglossum/ Lemboglossum/ Rhynchostele cordata that occurs from Mexico to Venezuela.

Many references put this one and C pastorelli as synomonous with C cordatum taking precedence but C pastorelli has a spine at either side of the column while C cordatum has a fringe as well as other differnces in the lateral sepals, the calli on the lip and the lip's overall shape. As of this moment C pastorellii is a synonym of C cordatum.

Synonyms *Oncidium cordatum Lindl. 1838
