Cattleyas
Cattleya intermedia w
Graham ex Hook., Bot. Mag. 55: t.
2851 (1828)
Distribution: Brazil. Normally has
up to five pink/purple flowers on
15 inch (40cm) canes. Shown here
are the alba form, and the variety
orlata which has a striking dark
purple lip. In the wild it may be
found on coastal rocks and sand
dunes ‘surrounded by the tide and
dashed by the spray and subjected
to the scorching sun ...’ (Withner).
Cattleya jongheana w
(Rchb.f.) Van den Berg,
Neodiversity 3: 8 (2008)
Distribution: Brazil. A dwarf plant
with pale pink flowers, but the lip
white and pink with a bright
orange throat, five inches (14cm)
across. The alba form is shown
here. Previously in the genus
Laelia, it was discovered in 1854 by
Mathieu Libon (who died shortly
afterwards, so its location was
lost) and sent to the Belgian orchid
nursery of de Jonghe.
Cattleya kautskyana w
(V.P.Castro & Chiron) Van den
Berg, Neodiversity 3: 8 (2008)
Distribution: Brazil. Flower similar
to C. harpophlla but the mid-lobe
is oval instead of long and narrow,
but as it grows in the same locality
(flowering a month later) along
with ‘hybrids’ between the two,
one might query if it is really a
separate species. Named for
Roberto Kautsky, who pointed out
the differences, in 1974.
