''Lycaste'' is a genus of [[orchid]]s that contains about 30 species with egg-shaped [[pseudobulb]]s and thin, plicate (pleated) [[Leaf|leaves]]. The horticultural abbreviation is Lyc.

== Description ==
''Lycaste'' [[flower]]s, like all orchid blooms, have three [[petal]]s and three [[sepal]]s. The petals are typically yellow, white, or orange, and the sepals are yellow, orange, green, or reddish brown. The petals and sepals may be marked sparsely or densely with red, reddish purple, purple, or reddish brown spots. The [[Labellum|lip]] (ventral petal) may be very similar to the other two petals, as in ''Lycaste aromatica'' or ''Lycaste brevispatha'', or colored quite distinctively, as in several subspecies and varieties of ''Lycaste macrophylla''. Most ''Lycaste'' flowers are medium in size, averaging about 5 to 10 cm, but ''Lyc. schilleriana'' is 16-18 cm across. Some ''Lycaste'' blooms have a unique fragrance - the scent of ''Lyc. aromatica'' has been variously described as cinnamon or clove. The blooms of the species ''Lyc. cochleata'', ''consobrina'', and ''cruenta'' also have a pleasant scent.

== Family Relationships ==

''Lycastes'' are members of the subtribe Lycastinae [[Schlechter]], which also includes the genera ''Anguloa'', ''Bifrenaria'', ''Horvatia'', ''Ida'', ''Neomoorea'', ''Rudolphiella'', ''Teuscheria'', and ''Xylobium''. Lycastinae is a member of the orchid tribe [[Maxillarieae]], which includes the large and well-known orchid genera ''Maxillaria'', ''Odontoglossum'', ''Oncidium'', and ''Stanhopea''. The [[Maxillarieae]] are part of the family Orchidaceae.

The World Checklist of Selected Plant Families, maintained by the [[Royal Botanic Gardens]] at Kew, is recognized by the American Orchid Society as the definitive authority on orchid taxonomy. The Checklist currently acknowledges 31 species of ''Lycaste'', 3 natural hybrids, 2 subspecies (and 1 nominate subspecies), and 1 variety. Orchid growers and orchid collectors, who tend to be taxonomic "splitters" more often than "lumpers" (see [[lumpers and splitters]]), recognize additional subspecies and varieties of ''Lycaste'', as well as alba (white) forms of several species.

== Taxonomy ==
The ''Lycastes'' have been divided into four sections, one of which has two subsections:
*Section Deciduosae - deciduous, that is, they usually lose their leaves during an annual dormant period
**Subsection Xanthanthae - have yellow to orange blooms; the name is from xantho - yellow, and anthos - flower
**Subsection Paradeciduosae - have pink-marked white blooms; the name is from para- similar or near, and deciduosae- deciduous ones
*Section Longisepalae - has very long sepals
*Section Macrophyllae - keep their leaves during dormancy; the name is from macro- large and phyllae- leaves
*Section Fimbriatae - typically have fringed lips

All but two of the ''Deciduosae'' have [[Spine (botany)|spine]]s at the apices of their pseudobulbs, that become exposed when the leaves are dropped - the exceptions are a ''Xanthanthae'' species, ''Lycaste lasioglossa'', and a ''Paradeciduosae'' species, ''Lycaste tricolor''. Both of these species lack spines, and may bloom when leaves are still present.

The recognized Xanthanthae species include:

*''[[Lycaste aromatica]]'',
*''[[Lycaste bradeorum]]'',
*''[[Lycaste campbelli]]'',
*''[[Lycaste cochleata]]'',
*''[[Lycaste consobrina]]'',
*''[[Lycaste crinita]]'',
*''[[Lyc
aste cruenta]]'',
*''[[Lycaste deppei]]'',
*''[[Lycaste lasioglossa]]'',
*''[[Lycaste macrobulbon]]''.

The ''Paradeciduosae'' species include:
*''[[Lycaste brevispatha]]'',
*''[[Lycaste tricolor]]''.

The ''Macrophyllae'' form a large complex, with subspecies and varieties that can be considered to be in the process of differentiating into new full species. The ''Macrophyllae'' species include:
[[Image:Lycaste Xytriophora.jpg|thumb|right|225px|''Lycaste xytriophora'']]
*''[[Lycaste dowiana]]'',
*''[[Lycaste leucantha]]'',
*''[[Lycaste macrophylla]]''
** ''Lycaste macrophylla'' var. ''desboisiana''
** ''Lycaste macrophylla'' subsp. ''macrophylla''
**''Lycaste macrophylla'' subsp. ''puntarenasensis''
**''Lycaste macrophylla'' subsp. ''xanthocheila''
*''[[Lycaste neglecta]]'',
*''[[Lycaste powellii]]'',
*''[[Lycaste skinneri]]'',
*''[[Lycaste xytriophora]]''.

The ''Fimbriatae'' species include:
*''[[Lycaste longipetala]]'',
*''[[Lycaste mesochlaena]]''.

Natural hybrids :
*''Lycaste × groganii'' (''Lycaste aromatica'' × ''Lycaste deppei'')
*''Lycaste × michelii'' (''Lycaste cochleata'' × ''Lycaste lasioglossa'')
*''Lycaste × smeeana'' (''Lycaste deppei'' × ''Lycaste skinneri'')

Hybrids
*''Angulocaste'' (''Anguloa'' x ''Lycaste'')
*''Cochlecaste'' (''Cochleanthes'' x ''Lycaste'')
*''Colaste'' (''Colax'' x ''Lycaste'')
*''Lycasteria'' (''Bifrenaria'' x ''Lycaste'')
*''Lycida'' (''Ida'' x ''Lycaste'')
*''Maxillacaste'' (''Lycaste'' x ''Maxillaria'')
*''Zygocaste'' (''Lycaste'' x ''Zygopetalum'')

A recently published (2003) revision of ''Lycaste'' by Henry Oakeley and Angela Ryan split off most of the species of section ''Fimbriatae'' as the new genus ''Ida''. The 34 species of ''Ida'' occur in South America or in the Caribbean Islands (''Ida barringtoniae''), while true ''Lycastes'' occur mostly in Mexico and Central America. The genus ''Ida'' is recognized by the World Checklist of Monocotyledons.
