and 27 genera (Versieux and Wendt 2005). Among these, Eduandreaselloana(Baker)
Leme, W Till, G.K. Brown, J.R. Grant & R. Govaerts deserves special attention be-
cause it is cited in the Rcview if the Brazilian Flora List Threatened by Extinction as vul-
nerable (VU), caused by the reduction of the population size, habitat fragmentation
and geographic distribution severely fragmented and known by few locations (www. In the red tist of endangered species of Minas Gerais' flora fac-

Figure2. Eduandreaseltoana characteristics.
Eduandrea selloanacan be characterized by its terrestrial habit, thick rhizome with
an abundant root system; abaxial surface of the leaf, scape and primary bract covered
with a thick layer of white tricome in contrast with the glabrous adaxial surface, green
leaves and blades with entire foliar margins; well elevated inflorescence above the fo-
liar rosette, with narrow primary bracts that don't form outlying or central tanks and
without the capacity of storing water; rachis partially visible in the basal portion of
the inflorescence because of the fascicule separation; biporate and supoliporate pollen
with reticule exine, and subglobose fruit bigger than the ovaries, green with persistent
chalice (Brown & Leme, 2005) (Figure 2).
Eduandreaselloanais an endemic species of Espinhaço range, growing exclusively
in riparian forest of the state of :MinasGerais (figure 1). Despite the citations of oc-
currence in Ouro Preto and Antônio Pereira, even recently, its populations could only
be found in Parque Nacional da Serra do Cipó (National Parque of Serra do Cipó), in
populations considered residual, according to (Leme 1998). From 1988 new collection
of E. selloanawere accomplished in Santana do Riacho and Palácios' region (Serra do
Cipó). In 2001, well conserved populations were located in Parque Natural do Caraça
(Caraça Natural Park) (Brown & Leme, 2005).
In 2006 Eduandrea selloanawas located in State Park of Serra do Rola-Moça (pESRM)
in a special protection area of Mutuca (APE-Mutuca). PESRlvI is located in the Cadeia

by the Decree 36.071 of 27 of September, 1994, the PESRM is situated in the county
of Belo Horizonte, Brumadinho, lbirité and Nova Lima, in Minas Gerais State, Brazil,
with an area of 394,109 ha. (Vicent, 1994).
The APE-Mutuca, is located in the municipal district of Nova Lima, MG, in the
coordinates 43° 58' W and 20° 02' 30"S, with maximum altitude of 1,448m and an
area of 1,250 ha. According to Kõppen's dassification its climate is mesothermal,
also denominated subtropical of altitude (Cwb), with fresh summers and well defined
dry season; the medium precipitation is of 1400 mm/year, being the trimester of
December-February responsible for more than 50% of the annual total. lts vegetation
is represented by Campo Rupestre Ferruginoso, Cerrado and Mata de Galeria, in fiat
mountains, low waves and strongly waved.
According to field's observations, the population of Eduandreasel/oanain APE-
Mutuca is found well conserved, presenting 404 individuals in an area of about 2km,
along the Mutuca river, between 1,045-1 and 1,153m altitude. This species is intimately
associated to humid environments, locating itself in the medium region of the ravine
along the Mutuca river, in day soil (Figure 3). Brown & Leme (2005) report that E.
sel/oanaoccurs in white quartzite sand, frequently among rocks.

underground rhizome.
Related to its reproduction type, it is possible to observe one or two ramets per
rosette. Propagation is also common by the formation of rosettes from the underground
thick rhizome (Figure 4). Inflorescences in the studied population have 44 flowers on
average. The flowering period varies from October to January. Its fruits contain 100-269
seeds. Many fruit present indications of herbivory (figure 5) probably caused by the
beetle Conotrachelussp. (Família Curculionidae) found in some inflorescences.
During the study Euglosideae bees were observed on the E. sel/oanaflowers. The
bees developed a high level of specificity related to particular types of flowers. The
flowers that co-evolved with the bees have outstanding and shiny blue petals, present-
ing special structures indicative of the position of the nectar, as can be observed in
A. sel/oana(Figure 7). These flowers also have as characteristic a type of platform for
the insect's landing.
Neither germinating seeds nor seedlings were observed in the field, however ger-
mination tests conducted in the Bromeliaceae Research and Conservation Unit (UPCB)
, of Viçosa Federal University indicated high germination viability. It was also tested
the cultivation from adult individuals verifying The development of four to five dones
per adult rosette was also observed in cultivation tests. These tests show the viability

The Serra do Rola-Moça State Park is located on the central southern portion of the Espinhaço Range, in a region denominated Quadrilátero Ferrífero (Iron Quadrangle). It comprises the municipalities of Belo Horizonte, Brumadinho, Ibirité and Nova Lima. The main vegetation types include the rocky grassland, semideciduous seasonal forest and savanna vegetation. This work aimed to study the floristics of the Bromeliaceae family in Serra do Rola-Moça State Park. Twenty-five species belonging to 11 genera were identified, and Dyckia is the most species-rich genus. Eduandrea selloana, Cryptanthus schwackeanus, Dyckia consimilis, D. densiflora, D. macedoi, D. simulans , D. schwackeana, D. trichostachya, Vriesea longistaminea and V. minarum are cited on the Minas Gerais Endangered Flora and Fauna Species List. Here we re-establish Dyckia oligantha as a species.

Field work and data from herbaria collections (2686 records) representing 283 taxa (265 species and 18 infraspecific taxa) of Bromeliaceae occurring at Minas Gerais state, southeastern Brazil, were analyzed in order to obtain distribution and diversity information, and to determine IUCN (The World Conservation Union) conservation status for each taxon. A map containing 1°×1° grid cells was used to identify priority areas for new research collections, areas of high species diversity, and Bromeliaceae conservation status. A clear decrease in Bromeliaceae diversity is observed between the eastern and the western portions of Minas Gerais, and low floristic similarities were found between neighboring grid cells. The rocky mountains of Cadeia do Espinhaço are considered the most important area for Bromeliaceae endemics. From the 283 taxa of Bromeliaceae that occur at Minas Gerais, 118 (42%) are considered threatened, and 124 taxa (44% of the total) do not occur inside any protected area. The region of the Quadrilátero Ferrífero in the southern portion of the Cadeia do Espinhaço is the most threatened, and urgent strategies for conservation of this rich Bromeliaceae flora are needed. Northeastern Minas Gerais, particularly the rocky outcrops or inselbergs located in the Jequitinhonha and Mucuri rivers drainage basins need additional collection efforts and conservation actions focused on these saxicolous taxa.
A cladistic analysis of morphological data for the genus Canistropsis is presented. With the exception of two species, C. selloana and C. correia-araujoi, results support Canistropsis as monophyletic. Canistropsis correia-araujoi is a suspected, natural bigeneric hybrid. Canistropsis selloana is transferred back into the monotypic genus Andrea. A taxonomic treatment, including a greatly emended description, and discussion of the distribution, habitat, and conservation of Andrea selloana is presented.
