Common Name Day's Caucaea [English Orchid Enthusiast 1800's]

Flower Size 1.2" [3 cm]

Found in Ecuador and Peru at elevations of 2300 to 3200 meters as a small sized, cold growing epiphyte with egg to pear-shaped, slightly laterally compressed pseuodbulbs enveloped basally by several imbricating, leaf-bearing sheaths and carrying 1 to 2 apical, linear to narrowly lanceolate, slightly leathery, dorsally folded longitudinally and keeled below, acute leaves that bloom in the fall and winter on an axillary, erect to suberect, to 12" [30 cm] long, racemose to loosely paniculate, fractiflex inflorescence arising from the leaf bearing sheaths and carrying 8 to 12 showy flowers.

CAUTION Now being considered to be a synonym of C phalaenopsis but the callus of the lip is different so I have left them separate for now.

Synonyms *Oncidium cucullatum var. dayanum Rchb. f. 1871; Oncidium dayanum (Rchb. f.) Stacy 1975; Oncidium phalaenopsis var brandtiae hort.
