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:
