Inflorescences terminal 3-33 flowered cymes, flowers mostly produced in glomerulate clusters, 0.9-10 × 1.4-5 cm, the peduncle 0.7-3.7 cm long, proximal inflorescence branches 3-15 mm long; bracts oblong to ovate often with an attenuate apex, 1.5-4 mm long; bracteoles narrowly ovate 1.4-3.5 × 0.4-0.8 mm, with an attenuate apex. Flowers 4-merous, sessile or with pedicels to 0.5 mm long; hypanthium 2.7-3.8 mm long, globose, 4-lobed, but lobing mostly obscured by bulla-based hairs, slightly constricted below the torus; free portion of the hypanthium 0.7-1.1 mm long, abaxial surface covered in bulla-based hairs from 1-3 mm long, and occasional, sessile, glandular hairs near the bases of the bulla-based hairs, adaxial surface (i.e., free portion) covered in small, bulla-based hairs; calyx teeth 2.1-3.3 × 0.4-0.8 mm, ascending or spreading, covered in bulla-based hairs; calyx lobes more or less triangular 1.3-2.5 × 1.4-2.6 mm, apex broadly acute, covered in bulla-based hairs abaxially and sessile, sparse, glandular hairs adaxially; calyx tube not tearing, 0.7-1.2 mm long with bulla-based hairs abaxially and sessile, glandular hairs adaxially; petals 4, white to rose colored, elliptic, 4-4.1 × 2.4-2.6 mm, with an acute apex and membranous margin, with one or two slightly bulla-based hairs produced abaxially, just below the apex, to 3.5 mm long; stamens 8; filaments 1.5-2 mm long, glabrous, anthers 1.2-1.4 mm long, with one dorsally oriented pore, anther thecae 1.1-1.3 mm long, anthers without a dorso-basal appendage or with a short appendage to 0.1 mm long; style 4-4.8 mm long, glabrous, not or only slightly dilated in the middle, collar absent, style subtended by a crown of multicellular, bulla-based hairs, which are slightly longer than the surrounding bulla-based hairs of the ovary apex, stigma punctate; ovary 1.5-2.8 × 2.5-4.3 mm, apex flat to convex, pubescent of bulla-based hairs, placentation axile with deeply intruded placenta, 4-locular; berries globose, 4-lobed, purple at maturity, 3.9-7 mm long (including calyx tube), 4.5-9 mm wide, seeds 0.6-0.8 mm long, obpyramidal, testa smooth, light brown, raphe black, smooth, extending the length of the seed.

Phenology.

Miconia limoides  has been collected in flower and fruit from January through August.

Distribution

(Fig. 23View Figure 23). Miconia limoides  only occurs in the southern peninsula of Hispaniola from western Haiti in the Massif de la Hotte (from one collection; Clase 4132; see Judd et al. 2015b) to southwestern Dominican Republic in the Sierra de Baoruco (Fig. 19View Figure 19). Only two collections (Ekman 5462, 9519) exist from the Massif de la Selle, Haiti from the Port-au-Prince area at Morne Malanga. It is likely that this species occurs more widely in the eastern part of the Massif de la Selle and other parts of Massif de la Hotte.

Ecology.

Miconia limoides  occurs in moist, tropical, broadleaf or mixed broadleaf-pine cloud forests ( Pinus occidentalis  ) over limestone-derived soils at elevations ranging from 1100-1400 m. The species is sympatric with Miconia lima  in both Massif de la Selle, Haiti, and Sierra de Baoruco, Dominican Republic. It also occurs with Henriettea barkeri  (Urb. & Ekman) Alain, Henriettea uniflora  Judd et al., Mecranium ovatum  Cogn, Meriania involucrata  , Miconia alainii  Judd & Skean, Miconia dodecandra  , Miconia howardiana  Judd et al., Miconia subcompressa  , Miconia tetrastoma  , Miconia umbellata  (Mill.) Judd & Ionta, and Ossaea gracilis  Alain.

Conservation status.

Miconia limoides  is likely endangered in the Massif de la Selle, Haiti (where it is only known from two Erik Ekman specimens), from habitat loss and the species is not protected in the Sierra de Baoruco of the Dominican Republic, where it is also threatened from anthropogenic disturbance. Miconia limoides  is only known from one collection in Massif de la Hotte from Parc National Pic Macaya (Clase 4132), and the area from where it was collected was heavily disturbed from local farming practices, so we categorize the species as endangered.

Discussion.

Miconia limoides  forms part of the Miconia lima  complex ( Majure and Judd 2013b) and is likely most closely related to Miconia phrynosomaderma  considering the morphological similarities of descending stem hairs with upward, recurved apices and broadly elliptical leaves. Phylogenetic analyses not including material of Miconia phrynosomaderma  place Miconia limoides  as sister to Miconia lima  , a species with which it is sympatric in parts of its distribution and potentially forms hybrids (see discussion under Miconia lima  ; Fig. 20 C–EView Figure 20).
