Notes     (Last Modified On 4/11/2018)

Ecology: Montane region. Elevation: 3000. Distribution: Endemic to the tropical Andes (Peru). The specific epithet is unfortunate; it refers not to the Amazon region but to the political subdivision. Assigned to section Acutifolia.

Ecología: Región montana. Elevación: 3000 m. Distribución: Endémica para Perú. El epíteto específico es infortunado; se refiere a la subdivisión política no a la región amazónica. Asignada a la sección Acutifolia.

Features noted by Crum (2002) for S, amazonense include the triangular stem leaves, slightly concave at the apex, efibrillose hyaline cells that are twice divided with large membrane on both surfaces, and the branch leaves exhibit rather numerous elliptic commissural pores on the outer surface and to three, rather large, rounded, thin-margined pores (or gaps) on the inner surface. Unfortunately the specific name amazonense is for the region, Amazonas, in northern most Peru, not the lowland ecoregion as one might infer.

Plants tawny, 5-6 cm. Stem cortex without pores; wood cylinder red-yellow. Stem leaves ovate-triangular, 1.2 mm, apex acute, slightly concave, margins strongly bordered by 4-5 cell rows, the border somewhat expanded toward the base; hyaline cells 1-2-divided, fibrils absent, with a large gap on both surfaces. Branches in fascicules of 3 (1 pendent). Branch leaves narrowly ovate, 1.1-1.2 mm, concave, margins bordered by about 3 rows of linear cells; hyaline cells on the outer surface with numerous (to 9) ringed, elliptic commissural pores, on the inner surface with 1-3 rounded, pores; in cross-section green cells triangular, exposed on inner surface, hyaline cells bulging on both surfaces.
