4 Bromelia from Bolivia + 2 New Ones, & Key

The genus Bromelia (Bromeliaceae) in Bolivia with the description of two new species from the Santa Cruz department Roberto Vasquez & Pierre L. Ibisch

Abstract: Counting two new endemic species described in the present article, Bolivia has six Bromelia species; the non-endemic species are B. balansae, B. hieronymi, B. serra, B. villosa. The genus, in Bolivia, is typical of the understory especially of the dry to semihumid forests and of savannas, between 150 and 1,400m. It does not occur in the very humid rain forests.
Bromelia arubaiensis sp. nov. is similar to Bromelia hieronymi, that is present in drier ecoregions in the south of Bolivia, but differs, among others, by wider leaves, a bipinnate, lepidote inflorescence, longer floral bracts and longer violet petals. It differs from B. binotii, found in the Atlantic rain forest of Brazil, by the wider leaves, narrowed between the sheaths and the blades, the bipinnate inflorescence, longer floral bracts and shorter petals.
B. ignaciana sp. nov. is similar to B. balansae but differs by the rose and suberect bracts of the scape and the inflorescence, a more elongate and narrower inflorescence, oblong-lanceolate, acuminate sepals and smaller and rose petals.

Key words: Bromeliaceae, Bromelia arubaiensis sp. nov., B. ignaciana sp. nov., Santa Cruz, Bolivia.

Introduction
The Bolivian Bromelioideae are less diverse and more widely distributed than the Pitcairnioideae: about 32% are Bolivian endemics (vs. 67% of Pitcairnoideae; IBISCH & VASQUEZ 2000, IBISCH et al. 2001). In spite of a generally very high rate of new discoveries in Bolivia, only a few of the new species of bromeliads that have been described in the last years, belonged to the Bromelioideae. All Bromelia species known until recently (KROMER et al. 1999) were rather `old taxa' (descriptions: 1879-1901). However, as a consequence of our intensified bromeliad collecting activities and studies, in this article, two new species of this subfamily can be described: Bromelia arubaiensis and B. ignaciana. Thus, six Bromelia species are known from Bolivia.

Taxonomic treatment
Characteristics of the genus: Plants terrestrial, rarely epiphytic, propagating by rhizomes or lateral shoots; leaves rosulate, with curved spines on the margin; inflorescence composed; sepals free or united, obtuse or attenuate, rarely mucronate; petals usually fleshy, united in a tube with free margins, without appendages; stamens included, the filaments forming a more or less long tube; fruit a succulent berry, relatively large; seeds few to many, complanate, naked.

HABITAT: Terrestrial forest species in an pre-Andean area nearby the Andean knee where the Chiquitano Dry Forest and Southwest Amazon ecoregions meet. The forest is mainly evergreen but less diverse than the more humid Amazon forests further northwards.

OBSERVATIONS: The species is similar to Bromelia hieronymi, that is present in drier ecoregions in the south of Bolivia, but differs, among other characters, by wider leaves, a bipinnate, lepidote inflorescence, longer floral bracts and longer violet petals. It is also similar to B. binotii, found in the Atlantic rain forest of Brazil, from which it is distinguished by the wider leaves, narrowed between the sheaths and the blades, the bipinnate inflorescence, longer floral bracts and shorter petals.
The new species is called after the private Arubai reserve of the Coimbra family where it is was discovered. It was illustrated by colored photographs in IBISCH & VASQUEZ (2000) as Bromelia sp. 1.

HABITAT: Bromelia balansae is a species of northeastern Bolivia. It is found in open savanna vegetation, especially of the Cerrado type. 150-800m.

O'Connor: Puerto Margarita, Rio Pilcomayo, 21°10'S, 63°50'W 4 May 1983,A. Krapovickas & Schinini 39087 (LPB).

HABITAT: This is a typical Gran Chaco species. It grows in dry forests on poorly drained and temporarily inundated soils, between 250 and 700m, together with Stetsonia coryne (Cactaceae), Copernicia alba, Trithrinax schizophylla (Arecaceae), Aspidosperma quebracho-blanco (Apocynaceae), and others.

OBSERVATIONS: The apical part of the stem and the sheaths of the leaves contain starch consumed by the indigenous peoples of the Chaco (especially Ayoreo). Collected plants are held into the fire until the leaves are toasted. The young stolons are consumed without cooking (ARENAS & ARROYO 1988). The leaves contain fibers that are extracted beating the leaves. Then they are dried, woven and converted into ropes, bags and other articles (ARENAS 1981).

HABITAT: Terrestrial between rocks at the Caparu table mountain and nearby the Las Torres camp of the Noel Kempff Mercado National Park.

OBSERVATIONS: B. ignaciana is similar to B. balansae in the general habit and the cylindric inflorescence with short floral branches.

The new species is dedicated to the San Ignacio municipality, one of the greenest and most forest-rich municipalities of Bolivia, thanks to the Noel Kempff Mercado National Park, with a high coverage of protected areas.

HABITAT: The Bromelia species with the widest distribution. It is found in lowland dry forests, as well as in dry to semihumid inter-Andean valleys and the montane Chaco and the Tucumano-Bolivian forest, from 150m to 1400m.

OBSERVATIONS: As in B. hieronymi, the young stems are consumed by the indigenous people of the Gran Chaco. In the quechua-speaking areas the plant is known as "chaguar" while in "guarani dominated" areas the species is called “caraguata” or "garabata" (ARENAS & ARROYO 1988).

Diversity and conservation aspects
In Bolivia, the genus is found exclusively in the eastern lowlands and adjacent areas. Only Bromelia serra is found in higher elevations in the Andes. All six species are present in the Santa Cruz department, while not more than two sympatric species have been recorded in the other lowland departments. This is due to the fact that the large Santa Cruz department has the largest portions of habitats apt for Bromelia species.
Most species prefer open, forest-free habitats or dry forests with an open canopy, and are adapted to drought wildfires. Generally, they tend to proliferate when forest is cleared anthopogenically and when cattle-ranching leads to the destruction of trees and shrubs. They form a rather impenetrable thicket and are accompanied by other spiny succulents like cacti. Possibly, the species most adapted to closed forests (and maybe less weedy) is B. arubaiensis sp. nov. This species has not been observed forming large populations locally. However, plants cultivated in Santa Cruz show that the species is rather tolerant to radiation and drought, and thus not dependent on intact (semi-) humid forest habitats. In general, the Bolivian Bromelia species should not face conservation problems, especially for being rather forest conversion-tolerant. The heavily used B. hieronymi is told to be wiped out locally nearby Ayoreo communities, due to the intensive use.
