  • Discussion

    Although no type has been found for Luma nannophylla, it is very likely that it belongs to this variety judging from the protolog.

    Myrceugenia ovata, var. nannophylla, mainly an Andean entity, typically inhabits cool areas along lakes and streams and in bogs. A map of its distribution is shown in Fig. 10. It often grows with Nothofagus antarctica in what appear to be cold air pockets. In the region of Lago Nahuel Huapi, it hybridizes with M. exsucca, a subject which will be discussed in the section on hybridization.

    Myrceugenia ovata var. nannophylla flowers from February to April and the fruits seem to mature about 12 months later. It is compared with M. pinifolia in the discussion of that closely related species.
