In perennial species each of these shoots is asynflorescence (Vegetti, 1991; Perreta et al., 2009).

This species is distinguished by its main axis of thesynflorescence with 37-71 branches; first branch on the main axis ofsynflorescence with 34-49 branches; second branch on the main axis ofsynflorescence with 8-10 internodes; articulate rachis internodes 1.9-3 mm long, with hairs 5.3-8.2 mm long; pedicel 1.62.8 x 0.1-0.2 mm, with hairs 5.3-8.2 mm long; and pedicellate spikelet 0.5-1 x 0.05 mm.

15Synflorescence an open panicle; spikelets long pedicellate.

Typology of thesynflorescence, development of extra floral nectaries and growth forms in

morphological sense, as asynflorescence (Troll, 1964; Rua, 1999;

The variables that contribute most to the first component (and their eigen values) are length of hairs on articulated rachis internodes (-0.30), length of hairs on pedicel (0.30), pedicellate spikelet width (-0.29), pedicellate spikelet length (0.28), length of articulated rachis internodes (-0.28), pedicel length (-0.28) and pedicel width (0.28), while the length of first branch on the main axis ofsynflorescence (-0.44), number of branches on the first branch (-0.40), number of branches on the main axis ofsynflorescence (-0.38) andsynflorescence length (-0.37) contributes to the second component.

Each of these shoots should be considered, in a morphological sense, as asynflorescence (Troll, 1964; Rua, 1999).

This group was defined as being perennial and leafy stemmed plants, leaves petiolate with petiole basally auriculate or decurrent and limb ovate-lanceolate or deltoid, usually 2-9 cm long, capitula usually radiate and several, arranged in corymbosesynflorescence, anthers basally obtuse, and style branches apically truncate with short sweeping hairs (Cabrera 1985, Cabrera et al.

Based onsynflorescence structure and life forms, Cuatrecasas (1976, 1979, 1986) divided this group into eight genera, six of them restricted to Venezuela and the Colombian Eastern Cordillera.

Synflorescence a false panicle made by 2-5 digitate racemes per peduncle, well exserted from the spathe.

The complete flowering branch system produced by an apical bud of the embrional axis or an innovation bud during a growth season is calledsynflorescence (Troll, 1964; Weberling, 1965, 1989).
