Orchid Naming Standards
(a.k.a. "What does that label mean?")

Home > Free Information > Orchid Names

All plants and animals may be classified using the International Code of Botanical Nomenclature.  Without going through the entire structure, we can say that all orchids belong to the Family Orchidaceae, and are grouped below that into various subfamilies, tribes, subtribes, and so on.  It is the next level down - the genus - upon which we concentrate.

The following sections delineate the proper way plants' names should be documented, and will help you understand exactly what that tag says:

Species

Cattleya intermedia var. coerulea subvar. aquinii ‘Big Blush’

Cattleya Genus
bulletLatin
bulletItalicized
bulletCapitalized
intermedia Species
bulletLatin
bulletItalicized
bulletLower case
coerulea Variety
bulletLatin
bullet"var." not italicized
bulletEpithet italicized
aquinii Sub-Variety
bulletLatin
bullet"subvar." not italicized
bulletepithet italicized
‘Big Blush’ Cultivar (Clone)
bulletNot Latin
bulletIn single quotes
bulletNot italicized
bulletCapitalized

Note that only the genus and species names are necessary, the variety and cultivar may not exist, i.e., Cattleya intermedia, although if they do exist, it is proper to use the name in its entirely.

Artificial Hybrids

Phalaenopsis Sweetie Bear ‘Sara Jane’

Phalaenopsis Genus or Hybrid-Genus*
bulletLatin

bulletCapitalized
Sweetie Bear Grex (Hybrid name)
bulletNot Latin
bulletNot Italicized

‘Sara Jane’ Cultivar
bulletNot Latin
bulletIn single quotes
bulletNot italicized
bulletCapitalized

*  While in this hybrid example, phalaenopsis was the genus of both parents, hybrid-generic names are used when more than one genus is involved in the breeding.  Often, in combinations of two or three genera, the names are combined, such as doritaenopsis (a cross between doritis and phalaenopsis) or sophrolaeliocattleya (sophronitis, laelia and cattleya).  When the hybrids get more complex, it is common to name the multigeneric hybrid after an individual, attaching an "-ara" to the end, as in potinara (cattleya, brassavola, laelia, and sophronitis).

Unnamed Hybrids

If a cross has been made, but has not been raised to blooming and registered with the International Orchid Registrar, it is common to simply list the parents.

Pescatorea lehmanii X Cochleanthes River's Edge

Pescatorea lehmanii
bulletFemale Parent
Cochleanthes River's Edge
bulletMale Parent

The female parent (also known as the capsule- or "pod" parent) is listed first.  Additionally, if the cross involves plants of the same genus, it can be listed once, simplifying the name, as in Paphiopedilum bellatulum X delenatii.  Sometimes those are enclosed in brackets - Paphiopedilum (bellatulum X delenatii).

Note that if this hybrid does get registered and named, both it and the reciprocal cross Cochleanthes River's Edge x Pescatorea lehmanii will have the same grex name.

Natural Hybrids

These are naturally occurring hybrids from locations where populations of similar plants overlap.  They can be either interspecific, within one genus, or intergeneric, between species of different genera.  The "X" that designates the plant as a natural cross, is often left off.

Interspecific:  Paphiopedilum X wellesleyanum
(Paph. concolor x godefroyae)

Paphiopedilum Genus
bulletLatin
bulletItalicized
bulletCapitalized
X wellesleyanum Hybrid
bulletLatin
bulletItalicized
bulletLower case

Intergeneric: X Dactyglossum mixtum
(Dactylorhiza fuchsii x Coeloglossum viride)

X Dactyglossum Hybrid-Generic Name
bulletLatin
bulletA combination of the two genus names
bulletItalicized
bulletCapitalized
mixtum Hybrid
bulletLatin
bulletItalicized
bulletLower case

Note that very often the "X" is left out of the name of natural hybrids, which is supposed to be reserved.for the man-made equivalents.

Use in Writing

When referring to a particular plant, capitalize the genus as stated above.  If, however, you're referring to a group of plants, the genera are not capitalized.  As an example:  "Of all of the vandas and ascocendas in my collection, my favorite is Ascocenda Princess Mikasa."

Awards

You will sometimes see some random-looking letters after the complete name of the plant, usually something like "AM/AOS."  That is an indicator that the particular plant (or it's grower, in the case of a CCM) has met or exceeded certain standards and has been given an award.  The characters before the slash tells the award, and those after tell the issuing authority.  The more common award levels are:

FCC First Class Certificate
AM Award of Merit
HCC Highly Commended Certificate
AD Award of Distinction
CBM Certificate of Botanical Merit
CCM Certificate of Cultural Merit
GM Gold Medal
SM Silver Medal
BM Bronze Medal

The issuing authority of the award may be a society or other convention of interested parties.  Those include, but are not limited to:

AOS American Orchid Society
RHS Royal Horticultural Society
HOS Honolulu Orchid Society
JOS Japan Orchid Growers Society
JOGA Japan Orchid Growers Association
WOC World Orchid Congress (preceded by the number of the congress)

When a plant gets multiple awards from the same society, or the same award from more than one society, hyphenation is used:  CBM-AM/AOS, or FCC/AOS-RHS.
