Description:
Description: Shrub 0.5-1 m tall. Leaves coriaceous, imbricated, obovate to more typically oblong-elliptic, mostly 2.5-4.7 x 1.2-1.8(-2.3) cm, acute to apically rounded with a 1-2 mm long apiculus, seemingly entire but actually indistinctly and minutely serrulate, glabrous on the upper surface except finely whitish-appressed-pilosulous near the base and inconspicuously ciliate especially in lower quarter, lower surface indistinctly and sparingly beset with both appressed reddish-brown, glandular trichomes more or less 0.2 mm long and also appressed whitish-pilosulous basally; petioles 2-3 mm long, moderately puberulous. Inflorescence a dense, axillary raceme with softly pilosulous or puberulous rachises and pedicels; floral bracts appressed, linear to lanceolate, 3-4 mm long, puberulent; pedicels distinctly articulate just beneath the hypanthium, 6-10 mm long; bracteoles appressed, linear to narrowly lanceolate, 2-3 mm long, puberulent. Flowers with calyx hypanthium campanulate to cylindric, ± 2.5-3.0 mm long and in diam., moderately puberulous with whitish trichomes ± 0.1-0.2 mm long; limb ± 0.8-1 mm long, slightly flaring; lobes triangular, acute, 1.2-1.8 mm long, puberulous externally and internally; sinuses broadly rounded; corolla cylindric, 8-10 x 4-5 mm, pink to red, externally appressed- to spreading-puberulous with moderately abundant hyaline trichomes ± 0.4 mm long and internally moderately to densely pilose with hyaline trichomes, the lobes reflexed, triangular, 1.5-2 mm long, white, densely pilosulous both externally and internally; stamens 10; filaments distinct, attached to the receptacle, ± 2.0-3.0 mm long, glabrous proximally but marginally with appressed-pilosulous hyaline trichomes distally; connective 1.0-1.2 mm long; thecae 2.5-3.5 mm long, coarsely granular, basally strongly incurved; tubules 2, separate to the base, 3.5-4.5 mm long opening by oblique, introrse pores ± 0.6 mm long. Berry not seen.
Distribution: Endemic to Costa Rica. Rare and endangered.
Type: Costa Rica. San José: Elfin forest of dead oak trees 4-10 m tall, along trail from Canaan to Chirripó via Los Angeles, north of Río Talari at 3200-3400 m, Burger & Leisner 7401 (holotype, DUKE; isotypes, F, MO).
