The Passifloraceae comprise between 400 (Killip 1938; Cervi 1997, 2000) and 520 species (MacDougal & Feuillet 2004), which are widely distributed throughout the Neotropics. Brazil is an important center of diversity of the family, where four genera and 138 species occur. Passiflora L. is the most diverse genus of Passifloraceae in this country, where there are 129 native species (Cervi et al. 2010). This work describes and illustrates P. kikiana Cervi & Linsingen, a new species from the Brazilian Amazon that belongs to subg. Passiflora, supersect. Passiflora, sect. Laurifolia (Cervi) Feuillet & J.M. MacDougal, ser. Laurifoliae Killip ex Cervi (MacDougal & Feuillet 2004).

Type: BRAZIL. Amazonas: Manaus-Porto Velho road, 3/VI/1976, fl. fr., T.R. Bahia 93 (holotype UPCB; isotype IAN).

Passiflora kikiana Cervi & Lisingen Passiflorae odontophyllae Harms ex Glaziou et P. nitidae Kunth affinis; a prima specie indumento puberulo, stipulis setiformibus asymmetricis, petiolo cum 2 vel 3 paribus glandulorum fungiformorum vel capitatarum, bracteis setiformibus, foliorum margine integro et corona quadrifaria distinguitur; a secunda pedunculis 3.5-3.7 cm longis, bracteis setiferis, petiolo 2 vel 3 paribus glandulorum, foliis e basi 5-nervis, corona quadrifaria et petalis rubris distinguitur.

Vines; stems cylindrical, minutely pubescent. Stipules c. 1.3 × 0.3 cm, membranous, arrow-shape, base asymmetric, with 3-5 glands along the margin, apex long-acuminate, hirsute. Leaves simple; petioles 2.5-2.8 cm long, with 2 or 3 pairs of fungiform or capitate glands; lamina 8.5-11 × 5-7 cm, membranous, ovate, base cordate, margin entire, apex acute, adaxially glabrous, abaxially pubescent, 5-nerved, actinodromous. Floral peduncle 3.5-3.7 cm long; pedicels c. 1 cm long; bracts 3 (2 opposed and 1 inserted above the other two), c. 1 x 0.3 cm, membranous, narrowly elliptical, apex acute, margin dentate. Flowers solitary or two per leaf axil, 5.5-6 cm diam.; calyx tube campanulate, 6-8 mm long, lobes 2.3-2.5 × 0.6-0.9 cm, membranous, lanceolate, obtuse at the apex, abaxially glabrous, greenish, adaxially reddish; petals red, the same size as the sepals; corona with 4 rows of filaments, the filaments in the outermost row reddish, subulate, 1.7-1.8 cm long, the filaments in the second row clavate at apex, c. 2 mm long, the filaments in the third row tuberculate, c. 1 mm long, the filaments in the innermost row filiform, clavate at apex, c. 5 mm long; operculum c. 1.2 cm long, erect, with a membrane at the base and capitate filaments at the apex, the membrane c. 2 mm long, with an adaxial tooth c. 1 mm long; limen 1.5-2 mm long, membranous, loosely surrounding the androgynophore; androgynophore c. 1.6 cm long; ovary globose, glabrous. Fruits green-yellowish when mature, 4.5-5.5 cm diam., globose. Seeds brown, foveate; aril white, c. 5 × 3 × 2 mm. Fig. 1

Additional specimens examined: BRAZIL. Acre: Manoel Urbano, 19/III/2002, fr., D.C. Daly et al.11445 (NY, UPCB); Rio Branco, 19/V/1991, fr., C.A. Cid et al.10107A (NY, UPCB); Rio Branco to Porto Velho, 4/II/1979, fl., fr., B.W. Albuquerque et al. 1332 (NY, UPCB). Amazonas: Manaus to Castanho, Km 18, 31/III/1985, fr., B. Nelson 1382 (INPA, MG, NY, UPCB). Pará: Santana do Araguaia, 18/II/1980, fr., T. Plowman et al. 8838 (MG, NY, UPCB).

Passiflora ser. Laurifoliae is characterized by being an herbaceous climber with cylindrical stems and tendrils; petioles and stipules with glands; entire or lobed leaves, which are glabrous to sparsely tomentose; three bracts subtending the pedicels; a campanulate calyx tube; a tubular or filamented operculum; and a membranous limen. Passiflora kikiana is morphologically similar to P. odontophylla Harms ex Glaziou and P. nitida Kunth, but they can be easily distinguished using the following key:

1. Corona fi laments arranged in many rows ...................................P. odontophylla 1'. Corona fi laments in 4-6 rows. 2. Petiole with 1 pair of sessile glands, leaves slightly serrate along the margin ........ ...................................................................................................P. nitida 2'. Petiole with 2 or 3 pairs of fungiform or capitate glands, leaves entire ................. ..................................................................................................P. kikiana

The specific epithet is in honor of the beautiful, lovely and dear granddaughter of the first author, Maria Francisca Cervi Sigel, who is affectionately called Kiki by her grandparents.
