This species inhabits inselberg forests near the sea at ca. 64 m elev. and montane rainforests at ca. 700 m elev. Flowers can be found from mid-March to August, fruits (immature) were collected only once in June.</p><p>Myrcia colpodes can be recognized in the field by its vinaceous and exfoliating trunk, young purplish and pendular leaves, lanceolate and strongly bullate mature leaves, pendulous, glabrous uniflorescences, in well-developed panicles, and externally glabrous flowers. This overall aspect fits the morphological concept of  Myrcia sect. Aulomyrcia . Within this section, the characteristic long leaves with adaxially raised midveins, the terminal conflorescences with well-developed and whorled uniflorescences, combined with flower buds with free calyx lobes, suggests its placement in “species group A” as circumscribed in Lucas et al. (2016: 652).  Myrcia colpodes is remarkable within this group due to its pubescent staminal ring, which contrasts with the internally glabrous flowers present in all other species of this group occurring in the Atlantic Forest.</p><p>Within the “species group A” of  Myrcia sect. Aulomyrcia, bullate leaves also occur in the Amazonian species  M. integra M.A.D. Souza &amp; Sobral (in Sobral et al. 2015: 212) and  M. maraana Sobral &amp; M.A.D. Souza (in Sobral et al. 2015: 222), as well as in  M. gigantea (O.Berg) Niedenzu (1895: 76) an Atlantic Forest species endemic from the Brazilian state of Bahia (Santos et al. 2020). These species also share subsessile leaves with barely visible petioles, but they can be distinguished by the characters given in Table 1.</p></div>	https://treatment.plazi.org/id/03D18797FFFAFFF9DDC4FDDFFD9AFC43	Public Domain	No known copyright restrictions apply.

This species inhabits inselberg forests near the sea at elevations ranging from 60–296 m, in a similar environment of that of  Myrcia colpodes, with which it may co-occur (Fig. 3). Flowers can be found from December to January, fruits from March to July.</p><p>Myrcia rubiginosa can be recognized in the field by its greyish light-brown trunk and longitudinally fissured bark, detaching as slightly thick, more or less rectangular strips, pinkish and pendular young leaves, pendular uniflorescences (even when flower buds are only beginning to develop) with distinctively brownish and tomentose axes, and relatively small flowers. As previously highlighted by Lucas et al. (2016: 653), the morphology of  Myrcia rubiginosa fits the morphological concept of M. sect.  Aulomyrcia, specifically the “species group D”, proposed in the same study.</p><p>As mentioned earlier, apart from our recent collection effort,  Myrcia rubiginosa was collected on three occasions: first in 1982, then in 2001, and finally in 2005. However, in all these instances, the collections were misidentified in herbaria. The 1982 collection (Andreata 387, RB) exemplifies the difficulty in accurately naming a specimen of  Myrcia sect. Aulomyrcia . Initially, it was identified as  Myrcia macrocarpa De Candolle (1828: 249), then as  M. insularis Gardner (1842: 530), followed by  M. amazonica De Candolle (1828: 250), and finally as  M. rubiginosa . All these species belong to  Myrcia sect. Aulomyrcia, although  M. insularis and  M. macrocarpa are assigned to the “species group A” (see Lucas et al. 2016), and can be distinguished from  Myrcia rubiginosa as this species has tomentose inflorescences and flowers (vs. puberulent to glabrous in  M. insularis and  M. macrocarpa).</p><p>Myrcia rubiginosa is indeed morphologically closely related to  M. amazonica, also placed in “species group D” of M. sect.  Aulomyrcia (see Lucas et al. 2016). These species share elliptic leaves, well-developed panicles and small flowers.  Myrcia amazonica, as currently circumscribed (see Santos et al. 2020), has a wide intraspecific variation and a relatively long list of synonyms. The presence and type of indumentum covering inflorescences and flowers, for instance, are considered polymorphic in t his species. Specimens wit h tomentose inflorescences and ovaries may be more difficult to distinguish from  Myrcia rubiginosa, but bark morphology on trunk and branches, along with the inflorescence display, are conclusive features to separate these species. In  Myrcia amazonica, the bark on trunk and branches is reddish and exfoliat ing, and in f lorescences are erect in display. In  Myrcia rubiginosa, the bark is greyish-brown, longitudinally fissured and detaching as slightly thick, more or less rectangular strips, and inflorescences are pendular.</p></div>	https://treatment.plazi.org/id/03D18797FFFEFFF6DDC4FC70FBDBF8CF	Public Domain	No known copyright restrictions apply.
