Family:Ericaceae
Description:Distribution and Ecology - Azuay: Cordillera de Alpachaca (headwaters of the Rio Jubones, between the Ríos Giron and Leon), near the pan-American highway at about km. 79, Camp E-405. The eastern Cordillera, 4 6 km. north of the village of Sevilla de Oro, Camp E-47UA, E-4717B. "Oriente" Border, Paramo del Castillo and surrounding forested areas (crest of the eastern cordillera on the trail between Sevilla de Oro and Mendez), Camp E-4869 (NY only); same locality, east of El Pan, Camp E-1632.

Discussion:

The cited specimens were obtained at elevations of 9,000 to 11,350 ft.; they were collected at the edges of paramos and sometimes formed the dominant groundcover on open slopes and paramo areas; in habit these plants often occur in dense mats in sphagnum meadows, propagating by long runners, sometimes almost buried in the sphagnum with only the tips exposed, or with the aerial parts stiffly erect and rarely as high as 0.5 m.; leaves shining, deep green above, paler beneath; bracts and calyx bright green; corolla green, red-tinged, brick-red, or rosy-pink (total range of color variation from green to red sometimes found in single plants); filaments white to bright pink, the anthers brown; fruit white, translucent.

This species, apparently endemic to Ecuador, i s less rare than indicated by the fact that I cited only two collections in 1933 (Brittonia 1: 228); I have since seen material from Carchi (Penland & Summers 871, NY), Imbabura (Penland & Summers 818, NY), and Azuay (Steyermark 53436, A, Ch). Some of the corollas on the Camp specimens are larger than previously noted, being up to 10 mm long. Nimber 4869 has leaf-blades notably larger than usual (up to 10 x 5 mm), but its flowers are typical for the species. Number 1632, from the same general locality, has one similarly large-leaved branch, from which arise lateral shoots with leaves normal for the species (1.5-3 mm. broad). These interesting specimens show what variable and undependable characters the shape and size of leaves are in this complex.
