Miconia albicans (Sw.) Triana (Melastomataceae) is a small tree up to 3 m high, distributed from southeastern Brazil to southern Mexico, and it is abundant in different physiognomies of the Brazilian cerrado and recently disturbed areas (Goldenberg, 2004; Allenspach and Dias, 2012). Flowers have a white‐greenish cream color and a light smell, and are organized in inflorescences. They flower at the end of the dry season, peaking in September (M. G. G, Camargo and L. P. C. Morellato, personal observations based on 60 individuals observed monthly for 6 yr). They have poricidal anthers, thus requiring buzz pollination to release pollen grains (Buchmann, 1983; Renner, 1989; Goldenberg, 2004). In this species, pollen grains and floral visitors are rarely observed; fruits are produced by obligatory apomixy (Renner, 1989; Goldenberg and Shepherd, 1998; M/ G. G. Camargo, personal observations).
Fruits are small berries, 7.5 mm wide and 5.9 mm long, with an average of 34 seeds per fruit; seeds are 0.72 mm wide and 1.02 mm long (MGG Camargo, UNESP, personal observations). The pulp of ripe fruits is mainly composed of water (76.6%), sugars (13.4%) and proteins (2.17%) (Maruyama et al., 2007). Fruits are organized in infructescences. On the basis of fruit size and color, three stages could be distinguished during fruit development: (1) inconspicuous, greenish‐gray, initially unripe fruits; (2) reddish, unripe fruits at an intermediate stage; (3) and fully expanded, green, ripe fruits. The intermediate unripe (hereafter “unripe”) and ripe fruits have a persistent red calyx (Appendix S1a and b, see Supplemental Data with the online version of this article). Miconia albicans is one of the most common species at the study site (Reys et al., 2013) and is responsible for 30% of the annual production of animal‐dispersed fruits in the local woody community (M. G. G. Camargo, unpublished manuscript). Ripe fruits are available mainly at the beginning of the wet season, peaking in November (based on unpublished data from 6 yr of monthly phenological observations of 60 individuals). They are an important food source consumed by different bird species, mainly generalists (Allenspach and Dias, 2012), marsupials Gracilinanus spp. (Pereira et al., 2009; Camargo et al., 2011b), and fallen fruits are also collected by ants (Christianini et al., 2012). As far as we know, there is no information in the literature whether reddish, unripe fruits are consumed by birds.
