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 spines 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,
- Lycaste 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:
- 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:
