Distribution, habitat and elevation range.
Endemic to central and southern Minas Gerais (Fig. 19B View Figure 19 ), mainly at Serra de Ouro Branco, Serra do Itacolomi, Serra do Cipó, Serra da Piedade, Serra da Moeda, Serra do Caraça, Serra do Gandarela, Serra de Lavras Novas, Serra dos Alves, Serra de Itabirito, Serra do Rola-Moça, Serra do Curral, Serra de Taquaril, Serra do Garimpo, Serra do Belo Vale, Diamantina Plateau and mountains in the Municipalities of Brumadinho and Mariana. It occurs on quartzitic or ferrugineous campo rupestre exposed to full sun at elevations between 868 and 1540 m.
Ecology.
Microlicia laniflora has a symbiotic relationship with arbuscular mycorrhizae ( Abrahão et al. 2019). This is likely related to phosphorus and nitrogen acquisition strategies ( Abrahão et al. 2019). This species easily colonises degraded campo rupestre areas and has been recommended for ecological restoration ( Amaral et al. 2013). According to Pereira (2011), its leaves develop increased asymmetry when damaged by insects. Vasconcelos et al. (2001) reported the use of M. laniflora for nesting by the endemic hummingbird, Hyacinth Visorbearer ( Augastes scutatus ), in campo rupestre at the Serra do Cipó.
Uses.
Leaf and stem extracts from Microlicia laniflora have antimicrobial activity against Staphylococcus aureus and Micrococcus luteus ( Cota et al. 2002; Ventura et al. 2007a).
Conservation.
This species is known from more than 100 herbarium specimens making it one of the better sampled species in the Trembleya s.s. clade. However, this sampling is geographically biased towards the surroundings of the MG-010 highway, where more than a half of these collections were made. The MG-010 highway is the main road crossing the mountains at south-eastern Serra do Cipó and provides easy access to large populations of M. laniflora . The EOO is 19,113.356 km2 and the AOO is 248 km2. Based on IUCN (2019) recommendations and criteria, we suspect that this species would be classified as Vulnerable (VU): B2ab(iii). Several populations of M. laniflora occur within the following conservation units: Parque Estadual Serra do Ouro Branco, Parque Estadual do Biribiri, Parque Estadual de Itacolomi, Monumento Natural Estadual Serra da Piedade, Monumento Natural Estadual Serra da Moeda, Parque Estadual da Serra do Rola-Moça, Parque Nacional da Serra do Gandarela, Parque Nacional da Serra do Cipó and RPPN Serra do Caraça (Natural Heritage Private Reserve), where M. laniflora is afforded protection.
Recognition and affinities.
Microlicia laniflora may be recognised by its branches, abaxial surfaces of the leaves and hypanthia that are densely covered by a lanose indumentum, white petals (rarely flushed with pink) that are 19.0-26.0 mm long and subulate calyx lobes 7.9-9.7 mm long. It appears to be most closely related to M. pentagona and M. chamissoana . Microlicia laniflora differs from M. pentagona by the branches, abaxial foliar surfaces and hypanthia densely covered by the lanose indumentum (vs. appearing glabrous, vernicose and minutely granulose), leaves with longer petioles 6.0-11.0 mm long (vs. 0.4-2.5 mm long) and margins entire throughout (vs. serrulate on the upper half), longer hypanthia 5.0-6.5 mm long (vs. 2.5-3.5 mm long) and longer petals 19.0-26.0 mm long (vs. 11.8-13.8 mm long), that are white, rarely flushed with pink (vs. magenta). For additional comparisons, see comments under M. chamissoana .
Notes.
The four varieties proposed by Cogniaux (1883-1888) were based mainly on differences in petiole length, leaf size and leaf shape. An examination of Cogniuax’s varieties and many additional collections showed these purported differences to be inconsistent with much size overlap in the characters he used to delimit his infraspecific taxa. The ovate leaf shape that Cogniaux (1883-1888) attributed only to Trembleya laniflora var. genuina is present in most of the individuals examined, along with a great deal of variation in leaf and petioles sizes. Cavalcanti et al. CFSC10628 (UEC), for example, has ovate leaves (a feature attributed only to Trembleya laniflora var. genuina ) and well-developed petioles (a feature attributed to the varieties Trembleya intermedia , Trembleya grandifolia and Trembleya acutifolia ). This specimen could be identified as Trembleya laniflora var. intermedia since its leaf measurements match those of the protologue (3-4 cm long). However, when comparing the Cavalcanti specimen with the type of var. Trembleya intermedia (Gardner 4601), it is clear that this variety has lanceolate leaves that are very distinct from the ovate leaves of Cavalcanti et al. CFSC10628. Characters, such as leaf shape and size, also vary along branches of a single individual and, thus, do not constitute good diagnostic features to delimit varieties of this species.
According to Cogniaux (1883-1888), some of Glaziou’s collections of M. laniflora (his numbers 14740 and 14741) were made "in prov. Rio de Janeiro" [Rio de Janeiro State]. On the other hand, Glaziou (1908: 251) asserts that his number 14740 came from "Serra do Caraça, au Morro do Inficionado" and the number 14741 came from "Campo de São Sebastião, prés Ouro Preto", both sites located in Minas Gerais State. The labels of Glaziou 14740 and 14741 from P had annotations of collections’ sites similar to those shown in Glaziou (1908), while a duplicate of Glaziou 14740 from K has a label that says "14741 the same" and the location site is cited as "Environs de Rio de Janeiro et Ouro Preto". Due to these contradictions, the cited collections were not used for the geographical distribution summary of M. laniflora . The discordant data on Glaziou’s collections of Melastomataceae have been noted by Wurdack (1970) for other collections of Melastomataceae , such as Clidemia , Leandra , Macairea , Miconia , Rhynchanthera , Tibouchina and Tococa . This is the first report of dubious geographic information for a species of Microlicia . We found similar contradictory information on labels of Glaziou 14746 which is discussed in the comments under M. pithyoides .
