Gomes-Bezerra 12 (UB!)  .</p><p>Phenology:—Flowers from July to September and fruits from October to December.</p><p>Etymology:—The specific epithet refers to the Brazilian Federation Unit, which has the largest number of vouchers in the herbaria consulted.</p><p>Affinities:—This species is related to  Myrcia goyazensis Cambessèdes, a well known species well represented at CEN, HUEFS and UB (1964 to present) herbaria. The close resemblance to  Myrcia goyazensis might have misled collectors and reduced  Myrcia federalis collections to 15 specimens in the same herbaria. The two species can be distinguished through the following couplet:</p><p>1 Indumentum velutinous on young leaves and flowers; blades flat to slightly revolute, with 16–25 pairs of secondary veins, with parenchymatic sheath. Bracts and bracteoles deciduous after anthesis; bracts elliptic to oblong, navicular, 5.1–5.8 × 2.2–4.2 mm; bracteoles elliptic, deltoid to navicular, 2.2–8.1 × 1.4–4 mm .......................................................................................  M. goyazensis</p><p>1 Indumentum hirsute on young leaves and flowers; blades strongly revolute, with 25–32 pairs of secondary veins devoid of parenchymatic sheath. Bracts and bracteoles persisting after anthesis; bracts elliptic to lanceolate, navicular, 8–40 × 5–10 mm; bracteoles lanceolate, navicular, 5–6 × 0.5–0.8 mm ........................................................................................................  M. federalis</p><p>Comments:—The specimen Glaziou 21168 was cited by Glaziou (1905: 210) as a new species,  Myrcia angustifolia Glaziou; nevertheless, this species is not valid since it was not followed by a description; additionally it is a later homonym of  M. angustifolia (O.Berg) Niedenzu (1893) .</p><p>Habitat and distribution:—  Myrcia federalis colonizes open, and rocky grasslands with or without shrubs and rocky outcrops in the Federal District (Fig. 2).</p><p>Conservation status:—  Myrcia federalis has been mainly found outsite conservation units in private areas. Despite its wide distribution in the Federal District, small populations colonizing restricted areas suggest an endangered conservation status. According to IUCN (2011), this species was considered Endangered (EN) based on the B1 and B2.b.i.ii.iii and c.i.ii and D criteria. Another risk factor is the increasing land occupation in the Federal District mainly due to the expansion of residential areas.</p><p>Scanning Electron Microscopy:—  Myrcia federalis presents hypostomatic leaves, with epicuticular granular wax (Fig. 3B and C) on both surfaces; stomata with crests (Fig. 3A); simple trichomes on mature abaxial surface leaves and on both young leaves surfaces. Triangular pollen grains in polar view (or angle) (Fig. 3D) and oblate-spheroidal in equatorial view (or angle) (P/E=0.9), irregularly parasyncolpate with a verrucous surface. (Fig. 3D).</p><p>Foliar architecture:—  Myrcia federalis shows a brochidodromous-pinnate venation pattern with visible 5 th order veins; conspicuous on both surfaces; secondary veins, 25–32 pairs, diverge from midvein in 80–90˚ angles, an intramarginal vein is formed in obtuse angles at the meeting laces; branched exmedial intersecondary veins; alternatepercurrent tertiary veins; well developed areoles, 0.1–0.2 mm, (3-)4–5 sides, 260–300/cm 2; simple or absent ending ultimate veins, rarely bifurcate (Fig. 4C); intramarginal veins 0.8–1 mm from the margins; marginal vein in loops from the base (Fig. 4).</p></div>	https://treatment.plazi.org/id/CD1C8785F668CF76A0EC91C0F25D2160	Public Domain	No known copyright restrictions apply.
