A delightful miniature species. It's from Andy's Orchids (sold as Oncidium coloratum). The photos were taken on Nov 13, 2018. It is still a small plant, but it produced 2 inflorescences this year. The second one wasn't in bloom at the time of photos, but the flowers from the second inflorescence are still open now. I'm growing it at the cool-end of intermediate; max/min daily temperature of 29/18C (84/65F) in the summer and 21/13C (70/55F) in the winter.
