Phenology.

Miconia ottoschmidtii  has been collected in flower from January through July and in fruit from April through August.

Distribution

(Fig. 13View Figure 13). Miconia ottoschmidtii  occurs in northern Cuba in Pinar del Río (Pan de Guajaibón), Mountain of Guamuhaya of central Cuba, the Sierra Maestra of southern/eastern Cuba and Sierra Cristal.

Ecology.

This species occurs on montane evergreen forest, wet montane rainforest, from 400-1050 m in elevation on fersialitic soils or rarely on serpentine soils (e.g., Sierra Cristal). Some associated melastomes are Clidemia hirta  (L.) D.Don, Conostegia icosandra  (Sw. ex Wikstr.) Urb., Mecranium integrifolium (Naudin) Triana subsp. integrifolium  , Meriania albiflora  , Miconia matthaei  Naudin and Miconia prasina  (Sw.) DC.

Conservation status.

This species is widespread throughout Cuba occurring in Parque Nacional Pico Turquino, Parque Nacional Pico Cristal, Reserva Ecológica Lomas de Banao, Reserva Ecológica Pico San Juan, Parque Nacional Topes de Collantes and Elemento Natural Destacado Pan de Guajaibón, among other non-protected areas. However, the species is not abundant throughout most of its distribution, and is only known from one collection each from Pico Cristal and Pan de Guajaibón. The habitat for this species has been reduced in size and quality, thus, we propose a category of endangered for Miconia ottoschmidtii  .

Discussion.

Miconia ottoschmidtii  is the only Cuban member of an otherwise Hispaniolan clade containing Miconia lima  , Miconia limoides  , Miconia paralimoides  and Miconia pedunculata  (Fig. 2View Figure 2), as well as several other putative members of the clade ( Miconia phrynosomaderma  , Miconia marigotiana  , also Hispaniolan endemics). Of these taxa, Miconia ottoschmidtii  is most phenetically similar to Miconia lima  but can be differentiated from that species by the size of nearly all parts of the plant, with Miconia lima  being the larger of the two species. Also, Miconia lima  has broadly elliptic leaves, whereas those of Miconia ottoschmidtii  are narrowly elliptic (length/width ratio 1.3-4.6 cm in Miconia ottoschmidtii  and 1.5-2.2 cm in Miconia lima  ). Several specimens of Miconia ottoschmidtii  exhibit longer hairs along the stems and hypanthia than the typical granulate hairs generally exhibited by the species (i.e., Ekman 15794, 15912, Bécquer HAC-82434), and these plants are distributed more or less throughout the distribution of Miconia ottoschmidtii  . It should be noted that the specimen, Bécquer HAC-82434, is the northernmost and westernmost collection of the species in Cuba from Pinar del Río, Pan de Guajaibón, and is disjunct from other collections to the southeast in Guamuhaya montains. This population exhibits less well developed bulla-based hairs on the adaxial leaf surface and has larger and more broadly elliptic leaves (3.05-7.9 × 1.6-3.1 mm vs. 2.4-6.8 × 1-2.2 mm) than most populations from other regions of Cuba (Fig. 17E, FView Figure 17). It shows some phenetic similarity to Miconia asperifolia  , but clearly is in a clade with another accession of Miconia ottoschmidtii  from the Sancti Spiritus mountains ( Majure et al. 2015; Fig. 2View Figure 2), again showing the lability of morphological characters in the Lima  clade (see Majure et al. 2015).

The isolectotype sheet of Miconia ottoschmidtii  at BR is a mixed collection that also contains a fragment of Miconia norlindii  at the top center of the sheet.
