A valid name for the taxon known as Tillandsia bryoides auct. (bromeliaceae)/Un nombre valido para el taxon conocido como Tillandsia bryoides auct. (Bromeliaceae).

Tillandsia bryoides was validly described by J. G. Baker (1878) using A. Grisebach's name which appears on the specimen label of Lorentz 128. Four more additional vouchers appear in a separate paragraph following the original description: Gillies s.n. "On trees and bushes at the foot of the Cordillera, near Mendoza" (= T. pedicellata (Mez) A. Cast.; W. Lobb s.n. "South Chili" (= T. tricholepis Baker); Glaziou 3124 "South Brazil" (= T. tricholepis) and Christie s.n. "Parana" (= T. tricholepis), all of them housed in K except for Lorentz 128 which Baker had seen in BM (Till, pers. comm.). One year later, Grisebach (1879) modified the description of T. bryoides based on material from "near Cordoba", "near Tucuman" ( = Lorentz 73), and "near Jujuy", but describing longer leaves (8,5-10 mm vs 6,3-8,5 mm), shorter bracts (4,2-5,3 mm vs. 6,3-8,5 mm) and dismissing the possibility of 1-flowered inflorescences (23-flowered vs. 1-3-flowered). Nomenclatorically he created a younger and invalid homonym to Baker's name. About half a century later, Smith (1935) amended the description of T. bryoides because it "was described from a mixed sheet and the original description unfortunately contained both elements. One element had already been described as T. tricholepis, so that the description is amended here to fit the previously undescribed second element. The only definite correction is that the spikes never have more than a single flower instead of: 'Flowers 1-3' ". Based on Smith's (1935) statements and the data published in his monograph (Smith & Downs, 1977: 879) the original material on which Baker had described T. bryoides was a mixture of individuals of different taxa, and Smith established what part of the original material corresponded to his amended description of T. bryoides, being the lectotype of that name (see McNeill et al., 2006: Article 9.12, Ex. 7), and what part corresponds to T. tricholepis. Smith and Downs (1977) stated for the first time that this lectoptype (as "holotype") is housed in BM with one duplicate ("isotype") in M. These two specimens as well as further duplicates in G, GH, and WU all turned out to be T. tricholepis.

Based on the amendment and commentaries made by Smith (Smith, 1935; Smith & Downs, 1977), it can be inferred that at least part of the voucher P. Lorentz 128 housed in BM included elements of T. bryoides, in agreement with the original description published by Grisebach in Baker (1878) and amended by Smith (1935). But when Till (1989) looked for the lectotype of T. bryoides in BM, he only found half a sheet labelled as P. Lorentz 128 with elements of T. tricholepis. After a recent consultation (John Hunnex, pers. comm.), no other sheet of P. Lorentz 128 could be found in BM. The study of the duplicate kept in M (M-0111455) and another one found in MPU revealed that they both include only elements of T. tricholepis. The herbaria K and particularly CORD (Hunziker, 1960) and GOET, where P. Lorentz deposited his collections, do not possess duplicates of P. Lorentz 128. This search for isotypes of T. bryoides only produced two old specimens, K000321909 and GOET000424, labelled as probable isotypes of T. bryoides, but without information about the collector and locality, and they only include elements of T. tricholepis. All these facts support the inclusion of T. bryoides into the synonymy of T. tricholepis, already suggested by Till (1989). However, there is still a taxon of Tillandsia subgen. Diaphoranthema from central and northwestern Argentina, central Peru, Bolivia, and northwestern Paraguay, with yellow, sessile, solitary flowers and a glabrous floral bract, that has been known as Tillandsia bryoides (cf. Castellanos, 1945; Schinini et al., 2008; Subils, 2009), that Till (1989) distinguished as T. bryoides auct. This paper provides precisely a valid name for that taxon, an illustration, and a discussion of the relationships with its morphologically closest species.

Tillandsia minutiflora Donadio, sp. nov. TYPE: Argentina, San Juan, Depto. Valle Fertil, San Agustin de Valle Fertil, ladera del cerro, frente camping ACA, 850 m s.m., sobre Acacia, 14-XII1987, M. E. Mulgura, C. Antuna & E. A. Ulibarri 704 (holotype, SI). Fig. 1.

Tillandsiae tricholepidi similis, sed caulibus brevioribus, 1,5-3,5(-6) cm longis, foliis 3-nervatis, angustioribus, 0,5 mm latis; pedunculis semper reductis et 1-floris et bractea florali glabra, 1nervia, mediae sepalorum aequans bene differt.

Epiphytic, perennial, tiny herbs, with adhesive, reduced roots. Stems short, 1.5-3.5(-6) x 0.3 cm (leaves included). Leaves densely imbricated, spiral, appressed, erect, 5.5-6 x 0.5-0.7 mm; sheath thin, translucent, 2 x 1.7 mm, 3-nerved, blade shortly subulate, 3.5-4 x 0.5-0.7 mm. Inflorescence reduced to 1 flower partially hidden among the apical leaves. Flowering peduncle very short or reduced, which does not elongate by the fruit ripening. Peduncle bracts 2, similar to the leaves (in shape), but 1-nerved (exceptionally 3-nerved) and without foliose apex, 2.5-3.5 x 1.2-1.4 mm. Floral bract subulate, thin, glabrous (exceptionally with 2 or 3 apical trichomes), 1-nerved, half the length of the sepals, 2.5-3 x 1.5 mm. Flowers minute, 6.5 x 1.5 mm (calix tube diameter). Sepals lanceolate, (4-)5(-7)-nerved, 4.8-5.5 x 1.2 mm densely lepidote on the distal half. Petals linearoblong, 5.5-6.5 x 1 mm, yellow. Stamens 2.6 mm, deeply included, filament 1.5 mm, anthers at the level of the stigma, 1.1 mm. Gynoecium 2 mm, ovary as long as the style, stigma subcapitate. Ovules numerous. Capsule cylindrical, oblong, 20 x 0.5-1 mm, valves straight. Seeds many, comose.

Distribution and habitat. Tillandsia minutiflora grows from central Peru (Till, 1989, sub T. bryoides auct.) through Bolivia up to central Argentina and northwestern Paraguay, with a disjunct area in southern Buenos Aires (Sierra de la Ventana). Its geographical distribution includes areas with altitudes between 600 and 2600 m (Till, 1989, sub T. bryoides auct.). Tillandsia minutiflora is an epiphytic species usually growing on bushes and small trees in "del Monte" phytogeographical province, but it can also colonize rocks.

[FIGURE 1 OMITTED]

Observations. Tillandsia minutiflora is morphologically close to T. tricholepis, and differs by the shorter, slender stems, and narrower leaves with 3-nerved sheath, 1-nerved bracts (both peduncle and flower), inflorescence always 1flowered, with a very reduced peduncle which does not elongate with fruit ripening, and a glabrous floral bract, shorter than the sepals. After the study of numerous vouchers, and cultivation of abundant material of Tillandsia tricholepis, there is a strong morphological support to consider T. pedicellata as a valid independent taxon from T. tricholepis because the former has deep purple flowers, sepals glabrous and 3nerved, bracts 1-nerved, and leaves with 3nerved sheath. To clarify the limits among Tillandsia tricholepis, T. pedicellata, and the new species T. minutiflora, an additional comparative table is here presented (Table 1).
