Passiflora fuchsiiflora Hemsl., Icon. Pl. 26: pl. 2553. 1898. Figs 2C, D View Figure 2 , 3C, D View Figure 3


Lianas; tendrils robust, glabrous. Stipules not seen. Petioles with two glands on the terminal end of the adaxial side. Blades 13.2-15.2 × 11.2-13.5 cm, chartaceous, widely ovate, apex round to slightly emarginate, base slightly to deeply cordate, glabrous on both sides; margins non-undulate, glandular; 11-14 pairs of secondary veins, arcuate. Bracts diminute, linear-setaceous, alternate. Flowers arranged in a racemose inflorescence, hypanthium cylindrical; sepals linear-oblong, pink; petals linear-oblong, pink; corona with 3 series of filaments, dark purple, filaments of first series subdolabriform, laterally attached filaments, filaments of second series tuberculate to tuberculate-triangular, filaments of third tuberculate; operculum straight, membranous, non-tubular, included, apex fimbriate; trochlea absent on the androgynophore; ovary obovoid to oblongoid, glabrous. Fruits not seen.


Pollen grains medium-sized (ca. 38.4 µm), prolate spheroidal, 6-colporate, colpi long, narrow, three endoapertures lalongate (ca. 7.6 × 11.0 µm), unique for each pair of ectoaperture, sexine reticulate, heterobrochate; muri (ca. 1.2 µm) simple columellate, sinuous, continuous, with perforations, without high columellae, not apparent, tectum surface mostly curved, lumina slightly ornamented, small (ca. 4.0 µm diam.) (Fig. 3C, D View Figure 3 ).

Distribution and ecology.

It is known to occur in Guyana, French Guiana, Suriname, Venezuela and Brazil. A single specimen collected in 1993 at the Indigenous Reserve of Yanomani, state of Amazonas, by W. Miliken 1801, was originally identified as P. fuchsiiflora . Until the present contribution, this was the only specimen of P. fuchsiiflora known for Brazil. Nonetheless, this specimen actually belongs to P. balbis Feuillet. Two specimens from the state of Amazonas, municipality of Presidente Figueiredo, at the Biological Reserve of Uatumã, are here correctly identified as P. fuchsiiflora . Thus, this species is recorded for the first time in Brazil based on the aforementioned specimens. In Brazil, P. fuchsiiflora is restricted to the state of Amazonas, growing in Igarapé formations.

Taxonomic comments.

Passiflora fuchsiiflora belongs to P. subg. Astrophea, sect. Botryastrophea, ser. Carneae . It possesses widely ovate and chartaceous leaf-blades, with round to slightly emarginate apex, added to the three filament series of the corona, with subdolabriform outer filaments and the two inner series with tuberculate filaments. The pollen grains possess reticulate sexine with small lumina and, for this reason, the pollen was included by Mezzonato-Pires et al. (2017) in the type IV pollen group.
