34. Meriania vilcabambensis Wurdack, Phytologia View in CoL 21(6): 353 (1971).

Type:— PERU. Cusco: Prov. La Convención, Cordillera Vilcabamba , Knox’s Cascade , c. 1 km north of Camp 2 ½, NE 14 km walking distance from the Hacienda Luisiana and the Apurimac River , 1730 m, 12°35’S, 73°35’W, 28 Jun 1968 (fl.), T. Dudley 10595 (holotype: US! [barcode 00120393 ]; GoogleMaps isotype: US! [barcode 02925667 ]) . ( Figure 69 View FIGURE 69 ).

Comments:— Meriania vilcabambensis is a poorly known species, and only the type has flowers at anthesis. It is characterized by its lobed calyces with small claw-shaped dorsal projections (ca. 3 mm long; Fig. 69E–F View FIGURE 69 ), dimorphic stamens, stamen connectives with ascending dorsal appendages, and antesepalous stamen connectives with laterally expanded descending dorso-basal appendages ( Fig. 69G View FIGURE 69 ). Meriania axinioides Gleason , a species endemic to Bolivia, has leaves similar to M. vilcabambensis , but the former differs by its glabrous flowers (vs. furfuraceous in M. vilcabambesis , Fig. 69C View FIGURE 69 ), calyces with conical dorsal projections not exceeding the apex of the lobes (vs. small claw-shaped dorsal projections exceeding the apex of the lobes), and petals 9–10 mm long (vs. ca. 16 mm long).

Distribution and phenology:— Meriania vilcabambensis is endemic to southern Peru (Department of Cusco) and grows in montane forests at 1100–1730 m ( Fig. 21 View FIGURE 21 ). It has been collected in flower in June.

Specimens examined:— PERU. Cusco: Prov. La Convención, Camp 2 ½, ca. 14 km walking distance NE from Hacienda Luisiana and the Apurímac River , 1730 m, 12°30’S, 73°30’W, 28 Jun 1968 (fl. bud), T. Dudley 10583 ( US!); GoogleMaps Dist. Echarate, Km 59 al 61 del Derecho de Via del Gaseoducto Camisea , margen izquierdo del río Poyentimari , 1100–1150 m, 09 Apr 2007 (fl. bud), S. Baldeón et al. 6719 ( USM!), GoogleMaps Santa Ana, Kepashiato , 1167 m, 12°44’02”S, 73°22’03”W, 19 Aug 2006 (fl. bud), L. Valenzuela et al. 7494 ( MOLF!, NY!, USM!) GoogleMaps .
