Located in wet forests at 600-1,200 m in the southern Cordillera de Tilaran of Costa Rica north- ward to Volcan Miravalles. Collected in flower July to September and in November; in fruit February, June, August, and October to November. This new species is unusual in Rudgea because of several characters: its 6-merous corollas with appendaged lobes longer than the tube, vs. 4-5- merous corollas with the tube longer than the un- appendaged lobes in most other species; its usually solitary or rarely three flowers, in contrast to five or usually more flowers in pyramidal inflorescences in most other species; and its seven stamens, in contrast to four or five in most other species. This new species is most similar to the sympatric R.

skutchii Standley, which is found at 50 to 1,200 m in wet forests from Colombia north to the Mon- teverde area in Costa Rica. Rudgea skutchii also has appendaged corolla lobes longer than the tubes, but it is easily separated by its 5-merous corollas with lobes 6-8 mm long, inflorescences with 5-15 flowers, and shortly truncate to rounded or cordate leaf blades borne on petioles 0-6 mm long.
