Oncidium henckenii
Oncidium henckenii is an old name (Schomburgk ex Lindley, 1855) that appears to be a spelling of Oncidium henekenii, now Tolumnia henekenii, the small bee-mimic orchid of Hispaniola. If your plant is that species, it is a hot, very bright, dry-scrub twig epiphyte that wants daily drying and a dry winter.
Where it grows wild
Assuming it is Tolumnia henekenii: a tiny fan-shaped twig epiphyte on shrubs and cacti in dry lowland scrub and thorn woodland. This identity is inferred from the name, not confirmed by records.
No records under this spelling; Tolumnia henekenii grows near sea level to a few hundred metres.
