03963037593C916EFCE6FCE3FA13FE67.taxon	description	Perennial taxa native to the New World, with knotty or spreading rhizomes. Spikelets in pairs. Rachilla internodes more or less elongated, hence upper florets stipitate. Indumentum of unicellular hairs, hairs smooth walled, apex acute, whitish-silvery, sometimes whitish with purplish tints or ochraceous, abundant in upper glume and lower lemma (scarce in D. laxa), generally exceeding the length of the spikelet and spreading at maturity.	en	Medico, Julia Mariela Lo, Tosto, Daniela Sandra, Rua, Gabriel Hugo, Agrasar, Zulma Esther Rúgolo de, Scataglini, Maria Amalia, Vega, Andrea Susana (2017): Phylogeny of Digitaria Sections Trichachne and Trichophorae (Poaceae, Panicoideae, Paniceae): A Morphological and Molecular Analysis.

03963037593C916EFCE6FCE3FA13FE67.taxon	diagnosis	Morphological Diagnostic Characters of Digitaria sect. Trichachne — HABIT AND VEGETATIVE SHOOTS — Taxa are perennial and all native to the New World. Most of the species exhibit a short rhizomatous knotty base, with internodes slightly developed and coated with pubescent cataphylls, although D. swalleniana and D. catamarcensis form spreading rhizomes because they have more numerous and elongated internodes.	en	Medico, Julia Mariela Lo, Tosto, Daniela Sandra, Rua, Gabriel Hugo, Agrasar, Zulma Esther Rúgolo de, Scataglini, Maria Amalia, Vega, Andrea Susana (2017): Phylogeny of Digitaria Sections Trichachne and Trichophorae (Poaceae, Panicoideae, Paniceae): A Morphological and Molecular Analysis.

03963037593C916EFCE6FCE3FA13FE67.taxon	description	SPIKELETS — Spikelets are arranged on the rachis in groups of two, one sub-sessile and the other one pedicellate. Pedicels are scabrous, with some prickles scarcely exceeding their summit (Fig. 3 A), never forming a coronula of hairs. Spikelets are ellipsoid (D. hitchcockii), ovate and abruptly acuminate (D. californica), or, in the majority of species, lanceolate to narrowly lanceolate with an acuminate apex. Rachillas have elongated internodes between the lower and upper glumes, upper glume and lower floret, and between lower and upper floret; for this reason, the upper floret is considered stipitate (Fig. 3 B – C). Internode elongation was also observed in D. eggersii and D. pittieri (Fig. 3 C), although Henrard (1950) regarded the upper floret as non-stipitate in both taxa. PILOSE INDUMENTUM OF THE SPIKELETS — Hairs are unicellular, smooth-walled, spreading at maturity, whitish-silvery, sometimes with purplish tints, or ochraceous, apex acute. In most taxa, the upper glume and lower lemma are densely hairy, with hairs usually longer than the spikelet length, with the exception of D. laxa (Fig. 3 D – E). In D. laxa the lower glume is glabrous and both the upper glume and lower lemma have short ochraceous hairs along the margin, shorter than the spikelet length. UPPER GLUME — Most of the species have a 3 - nerved upper glume with hairs between the nerves and along the margin, with the exception of D. laxa that is 1 - nerved and with some short marginal hairs. LOWER LEMMA — The midnerve may be distant from lateral ones (not equally spaced in D. californica, D. catamarcensis, D. insularis, D. patens, and D. sacchariflora; Fig. 3 F) or equally spaced in the remaining taxa (Fig. 3 G). Between the nerves, hair distribution occurs in one of four different patterns: pilose between the nerves and along the margin (exclusive of D. hitchcockii; Fig. 3 H), glabrous on both sides of midnerve and pilose in the remaining zones (D. californica, D. catamarcensis, and D. patens; Fig. 3 F), glabrous on both sides of midnerve and alternately pilose and glabrous in the remaining zones (D. eggersii, D. insularis, D. pittieri, D. sacchariflora, and D. tenuis; Fig. 3 G), and only pilose along the margin (D. laxa, D. similis, and D. swalleniana). UPPER FLORET — Most of the species have lanceolate or narrowly lanceolate upper florets with acuminate apices (Fig. 3 I). Digitaria californica is distinguished by ovatelanceolate upper florets with abruptly acuminate apices (Fig. 3 J), whereas D. hitchcockii is recognized by its lanceolate upper florets with acute apices. The rough texture of the upper florets is related to their epidermal cells having strongly undulated walls, each cell with a distally located papilla (Fig. 3 K). These cells are variable in size and number of undulations among species.	en	Medico, Julia Mariela Lo, Tosto, Daniela Sandra, Rua, Gabriel Hugo, Agrasar, Zulma Esther Rúgolo de, Scataglini, Maria Amalia, Vega, Andrea Susana (2017): Phylogeny of Digitaria Sections Trichachne and Trichophorae (Poaceae, Panicoideae, Paniceae): A Morphological and Molecular Analysis.

039630375932916BFF58F8ADFF16FEC5.taxon	discussion	Observation — The type of Trichachne sacchariflora Nees is composed of three specimens collected by Sellow, Martius, and Sieber. The first two specimens were collected in Brazil and the last one on Martinique Island. Based on the geographic distribution of D. sacchariflora (Vega & Rúgolo de Agrasar 2003, 2012), this species is exclusively distributed in Central America (Guatemala, El Salvador) and South America (Argentina, Brazil, Paraguay, Perú, Venezuela, Colombia, and Uruguay), so the identity of the specimen collected by Sieber is dubious. These three specimens are no longer at B because they were destroyed during the Second World War (R. Vogt, pers. comm.). Neither duplicates of these collections nor an illustration exists in other herbaria for a lectotype designation. On the other hand, Hackel in Stuckert (1904) published Panicum insulare (L.) G. Mey. var. sacchariflorum (Raddi) Hack. and included Trichachne sacchariflora Nees as one of their synonyms, mentioning “ Stuckert Herb. Arg. 54 ” with other specimens from different localities in Córdoba (Argentina). A particular mention was included about a specimen collected in Alta Gracia by Stuckert. In fact, Stuckert Herb. Arg. 54 corresponds to D. swalleniana Henrard (Rúgolo de Agrasar 1974: 103) and the other material was identified as D. californica var. californica (Rúgolo de Agrasar 1974: 96). Further, Vega and Lo Medico have examined the material collected by Stuckert deposited at CORD in the context of the ongoing project Flora de Córdoba, but none of them corresponded to D. sacchariflora. Hackel also cited “ Kneucker. Allg. Bot. Zeitsch. (1903) Gram. exsicc. pug. 1. p. 2 ”. Kneucker and Stuckert collected grasses in Córdoba (Argentina) in 1904; neither of these materials were identified as Panicum insulare var. sacchariflorum nor any other synonyms. Since no isosyntypes of the Sellow and Martius collections, as well as any original material of T. sacchariflora was localized in other herbaria, and according to Art. 9.16 of the International Code of Nomenclature (McNeill et al. 2012), it was necessary to select a neotype. The neotype herein designated [Brazil, Paraná, Ponta Grossa, camino a Tibagi, a 13 km de ruta BR – 376, 12 Dec 1992, Z. Rúgolo et al. 1691 (SI)] is consistent with Nee’ s diagnosis and it was collected relatively near the place where the Brazilian syntypes were collected.	en	Medico, Julia Mariela Lo, Tosto, Daniela Sandra, Rua, Gabriel Hugo, Agrasar, Zulma Esther Rúgolo de, Scataglini, Maria Amalia, Vega, Andrea Susana (2017): Phylogeny of Digitaria Sections Trichachne and Trichophorae (Poaceae, Panicoideae, Paniceae): A Morphological and Molecular Analysis.
