Key to Species

 
      Bejaria Mutis ex Linnaeus (Ericaceae, Vaccinioideae, Rhododendroideae), is a genus of 15 species of trees and shrubs.  It is characterized by 7-merous flowers, free petals, capsular fruits, non-appendaged anthers, and viscin threads intermixed with the pollen tetrads.  It is sometimes considered morphologically and anatomically isolated within the Rhododendroideae.
     A neotropical and subtropical genus of 15 species found in Florida, Cuba, and central Mexico south to Bolivia and east to Guyana. More detailed, species of Bejaria are found in the southeastern United States (1 sp.), western Cuba (1 sp.), central Mexico to scattered localities in Central America (1 sp.), and in South America from Colombia south to Bolivia and east to Guyana (13 spp.).  Four species (B. aestuans, B. resinosa, B. sprucei, B. mathewsii) are highly variable and widely distributed; the other eleven species are morphologically uniform and only locally distributed. Bejaria is a common plant of the subpáramo and upper montane forests of the Andes and, like other Ericaceae, it often invades recently disturbed areas such as roadsides

 

    Bejaria was revised twice in the twentieth century; first by Fedtschenko and Basilevskaja (1926, 1928), and later by Mansfeld and Sleumer (1935). Camp (1941a) revised the North American (including Mexican) species of Bejaria. He suggested that much of the variation in Bejaria was due to hybridization among a very few species.  Clemant's (1965) revision differs notably from the previous ones in the great importance given to corolla shapes and the minor role given indumentum and inflorescence characters in determining species.  He found the corolla shape to be the preeminent character in the genus, followed in importance by characters of leaf shape, leaf size, and petiole length.
     One of the most striking aspects of Bejaria are the different corolla shapes.  Melampy (1987) found that B. resinosa --a species with large tubular and fusiform corollas-- was visited by a variety of hummingbirds and insects, but that only some of the hummingbirds and Bombus (Bombias) robustus Smith were pollinators, the other visitors were stealing nectar.  Little is known about the pollination of the other Bejaria species.  Several different pollination syndromes are probably present based on floral visitors and extrapolation from other Ericaceae.  Flowers of species with spreading and campanulate corollas are visited and probably pollinated by bees.  Bejaria racemosa is visited by honey bees, Apis melifera (Clemants, 1995b), and B. aestuans is visited by honey bees and other unknown bees (Clemants, 1995b).  Flowers of species with small tubular corollas with long exserted stamens are probably pollinated by bees.  Clemants (1995b) observed and collected oil-collecting bees (Centris flavifrons Friese) and wasps (Scolia sp.?) visiting B. sprucei flowers.  No information is known about the pollinators of species with globose-campanulate, salverform, or infundibular corollas.
     Bejaria, the "Rose of the Andes", was once prized for its large brilliantly colored flowers, but in recent years it has not been widely cultivated.  Four species were known in cultivation in 1854 (Lindley & Paxton, 1850), but by 1953 no species were known to be cultivated in Great Britain (Preston, 1953).  Only one species, B. racemosa, is cultivated and available from United States nurseries and a second species, B. resinosa, available from a European seed house (Clemants, 1995b).  Bejaria probably lost favor as an ornamental because of the difficulty in cultivating the species.  It requires a cold, moist greenhouse, but otherwise the procedures for growing azaleas (Lindley & Paxton, 1850) or Agarista (G. Don, 1834) are recommended.  Considering its beautiful and diverse flowers, Bejaria needs to be reconsidered as an ornamental and proper cultivation techniques identified.
     Bejaria is used locally for wood working, as a medicinal, and as fly paper.  Bejaria wood, one of the few attractive ericaceous woods, is reportedly used to a small extent in turnery and cabinet making (Record & Hess, 1943).  A few species are used medicinally, mostly for heart and lung ailments (see B. aestuans and B. resinosa in Clemants, 1995b).  One of the more interesting uses of Bejaria is as fly paper.  Apparently flies are attracted to flowers of B. racemosa and glandular forms of B. aestuans, where they become stuck upon the viscous parts.  The resin on B. racemosa flowers has the same adhesive strength as commercially available glues for trapping insects (Eisner & Aneshansley, 1983).
     Several Bejaria species are widespread and occur in a variety of habitats, they are not endangered in any way, these include B. aestuans, B. resinosa, B. mathewsii, and B. sprucei.  But the majority of species are narrowly endemic, and where land use pressures are great, they may be endangered.  Of these species B. cubensis of western Cuba, B. subsessilis and  B. zamorae in southern Ecuador, B. ledifolia on Cerro Avila in Venezuela, and B. infundibula of eastern Peru, are probably the most threatened because they occur near habitation.

                           NOTES
     Unless otherwise stated transverse measurements of the rachis, pedicel, filament, and style were made at or near the base of the organ, whereas leaf, bract, and calyx lobe widths and calyx diameter were measured at their widest points.  Furthermore, the petals and calyx lobes are adaxially glabrous unless otherwise stated.
     Descriptive nomenclature follows Radford et al. (1974) except for the following:
