16. Leandra ulaei Cogn. in de Candolle & de Candolle (1891: 1186) . Lectotype (designated here):— BRAZIL. Santa Catarina: "Minas", February 1890, E.H.G. Ule 1453 ( BR 5192069 image!, isolectotypes B, destroyed, US!, W). Additional syntype: BRAZIL. Santa Catarina: E.H.G. Ule 1133 (BR image!). ( Figs. 73 View FIGURE 73 , 74 View FIGURE 74 , 75 View FIGURE 75 , 76 View FIGURE 76 )
Shrubs, 0.3–0.5 m tall. Branches, petioles, leaves, inflorescences, bracts and bracteoles covered by unbranched trichomes (0.8–1.5 mm), these sparser on leaf adaxial surfaces and denser on acrodromous nerves on leaf abaxial surface, petioles and inflorescences. Leaves isophyllous or slightly anisophyllous in each pair (up to 6:9 ratio); petioles (0.7)1–2(3) cm long; blades 5.5–10 × 2.5–4.5 cm, usually ovate, also ranging from lanceolate to elliptic, apex acuminate, base rounded, seldom obtuse or slightly cuneate, margin crenulate or entire, ciliate (1.5 mm),

REGINATO membranaceous; 5 acrodromous nerves, plus 0–1 additional pair of faint veins, plinerved, distant (2)4–12(15) mm above the base, acrodromous nerves slightly printed on adaxial surface and acrodromous nerves prominent, transversal flat on abaxial, reticulation slightly conspicuous. Inflorescences terminal, 1 per node, (3) 5–8 cm long, (1)2–4 pairs of opposite paraclades, accessory branches absent,> 10 flowers per inflorescence, these in glomerules; bracteoles 4–8 × 2–4.5 mm, lanceolate, elliptic, or slightly obovate, uniformly covered by unbranched trichomes, involucral, persistent. Flowers 5(6)-merous, sessile. Hypanthium 3.8–4.2 × 1.7–2 mm, campanulate to tubular, torus indumentum absent. Calyx tube 0.3–0.4 mm long; inner lobes 1.7–2.2 × ca. 1 mm, oblong with a rounded apex; external teeth 2.1–2.4 mm long. Petals white, 5.5–5.8 × 1.2–1.4 mm, linear to lanceolate, apex acuminate, glabrous, spreading at anthesis. Stamens 10, opposite to the style; filaments geniculation present, the larger 4.8–5.2 mm long, the smaller 4.1–4.5 mm long; anthers pink, the larger 4.3–4.5 mm long, the smaller 3.2–3.5 mm long, linear-subulate, dorsally curved, pore 0.11–0.14 mm wide, connectives dorsally produced below the anthers 0.3–0.8 mm, appendage present, a basal-dorsal bifurcation in the connective of larger anthers. Ovary 3-celled, 2.8–3.2 × 1.7–1.9 mm, 30–40 % inferior, apex sparsely covered by unbranched trichomes (ca. 0.8 mm). Style 10 mm long, sigmoid, opposite of the stamens, stigma ca. 0.2 mm diam. Berries purple, 6–6.5 × 4–4.5 mm. Seeds ca. 1 × 0.6 mm, long-obpyramidal, hilum covering 9/100 of the seed length, anticlinal cell walls flat.
Notes:— Leandra ulaei is only known from Santa Catarina. In this region it might be mistaken with L. hirta and L. melastomoides . From the former it is differentiated by the persistent bracteoles, absence of glandular trichomes and the ovate leaves, and from the latter by the predominantly ovate leaves with a rounded base and 5 or 5+2 acrodromous nerves.
