Larnax longipedunculata S. Leiva, E. Rodríguez Rodríguez & J. Campos (1998: 194)

Lectotype (designated here):— PERU. Cajamarca: San Ignacio, Caserío La Bermeja, bosques de neblina La Bermeja, Dist. Tabaconas, 1830 m, 4 January 1998, S. Leiva, J. Campos & E. Rodríguez 2098 (CONN 00055675! , isolectotypes: CORD 00004044!, F 2198658!, HUT 031885!, MO 04906479!).

The designated lectotype is the most complete specimen, consisting of a small branch with buds, two flowers and a fruit detached from the branch (Fig. 13 E). Furthermore, the long peduncle (Fig. 13 G) and the tiny calyx lobes are important characters observable in this specimen. Among the isolectotypes, the specimen housed at HUT has numerous flowers per inflorescence (8–15) which sets this species apart from the most morphologically similar species, L. nieva S. Leiva & N. W. Sawyer (2003: 106) (Fig. 14 F–J).
