Encyclopedia
Luisia, abbreviated as Lsa in horticultural trade, is a genus of epiphytical
orchids in family Orchidaceae
. It contains 40 species found in tropical
Asia
, Indian subcontinent, China
, Malaysia, Philippines
, Australia
, Polynesia
through Japan
.
The genus was named by Charles Gaudichaud-Beaupré
in 1829 for Luis de Torres, a Portuguese botanist.
The species in this genus are erect or climbing epiphytes with a monopodial
growth and with the same vegetative look as terete (= cylindrical or tapering and circular in cross-section) Vandas. The clumped stems branch near the base and carry alternate, terete leaves, conduplicate to the stem base. The axillary, short and elongate inflorescence
produce several flowers at a time. The flowers have a bee-like appearance. The fleshy labellum
is usually dark red and shows no spur
at its base. The labellum is rigid and consists of two parts. The basal part has short sidelobes and may have cushion-like glands. The somewhat ovate apical part sometimes shows toothed margins.
