CHAPTER H

NAMES of hybrids

Article H.6

H.6.1. A nothogeneric name (i.e. the name at generic rank for a hybrid between representatives of two or more genera) is a condensed formula or is equivalent to a condensed formula (but see Art. 11.9 and 54.1(c)).

H.6.2. The nothogeneric name of a bigeneric hybrid is a condensed formula in which the names adopted for the parental genera are combined into a single word, using the first part or the whole of one, the last part or the whole of the other (but not the whole of both) and, optionally, a connecting vowel. The use of a hyphen instead of or in addition to a connecting vowel is treated as an error to be corrected by deletion of the hyphen.

Ex. 1. ×Agropogon P. Fourn. (Quatre Fl. France: 50. 1934) (Agrostis L. × Polypogon Desf.); ×Gymnanacamptis Asch. & Graebn. (Syn. Mitteleur. Fl. 3: 854. 1907) (Anacamptis Rich. × Gymnadenia R. Br.); ×Cupressocyparis Dallim. (Hand-List Conif., Roy. Bot. Gard., Kew, ed. 4: 37. 1938) (Chamaecyparis Spach × Cupressus L.); ×Seleniphyllum G. D. Rowley (in Backeberg, Cactaceae 6: 3557. 1962) (Epiphyllum Haw. × Selenicereus (A. Berger) Britton & Rose).

Ex. 2. ×Amarcrinum Coutts (in Gard. Chron., ser. 3, 78: 411. 1925) is correct for Amaryllis L. × Crinum L., not “×Crindonna”. The latter formula was proposed by Ragionieri (in Gard. Chron., ser. 3, 69: 32. 1921) for the same nothogenus, but was formed from the generic name adopted for one parent (Crinum) and a synonym (Belladonna Sweet) of the generic name adopted for the other (Amaryllis). Because it is contrary to Art. H.6, it is not validly published under Art. 32.1(c).

Ex. 3. The name ×Leucadenia Schltr. (in Repert. Spec. Nov. Regni Veg. 16: 290. 1919) is correct for Leucorchis E. Mey. × Gymnadenia R. Br., but if the generic name Pseudorchis Ség. is adopted instead of Leucorchis, ×Pseudadenia P. F. Hunt (in Orchid Rev. 79: 141. 1971) is correct.

Ex. 4. Boivin (in Naturaliste Canad. 94: 526. 1967) published ×Maltea for what he considered to be the intergeneric hybrid Phippsia (Trin.) R. Br. × Puccinellia Parl. Because this is not a condensed formula, the name cannot be used for that intergeneric hybrid, for which the correct name is ×Pucciphippsia Tzvelev (in Novosti Sist. Vyssh. Rast. 8: 76. 1971). Maltea B. Boivin is nevertheless a validly published generic name, because Boivin provided a Latin description and designated a type, and may be correct if its type is not treated as belonging to a nothogenus.

Ex. 5. The nothogeneric name ×Anthematricaria Asch. (in Ber. Deutsch. Bot. Ges. 9: (99). 1892), proposed for hybrids with the parentage Anthemis L. × Matricaria L., was originally published as ‘Anthe-Matricaria’; the nothogeneric name ×Brassocattleya Rolfe (in Gard. Chron., ser. 3, 5: 438. 1889), proposed for hybrids with the parentage Brassavola R. Br. × Cattleya Lindl., was originally published as ‘Brasso-Cattleya’.

H.6.3. The nothogeneric name of an intergeneric hybrid derived from four or more genera is formed from the name of a person to which is added the termination ara; no such name may exceed eight syllables. Such a name is equivalent to a condensed formula.

Ex. 6. ×Beallara Moir (in Orchid Rev. 78(929): New Orch. Hybr. [1, 3]. 1970) (Brassia R. Br. × Cochlioda Lindl. × Miltonia Lindl. × Odontoglossum Kunth); ×Cogniauxara Garay & H. R. Sweet (see Art. H.8 Ex. 3) (Arachnis Blume × Euanthe Schltr. × Renanthera Lour. × Vanda W. Jones ex R. Br.).

H.6.4. The nothogeneric name of a trigeneric hybrid is either (a) a condensed formula in which the three names adopted for the parental genera are combined into a single word not exceeding eight syllables, using the whole or first part of one, followed by the whole or any part of another, followed by the whole or last part of the third (but not the whole of all three) and, optionally, one or two connecting vowels, or (b) a name formed like that of a nothogenus derived from four or more genera, i.e. from a personal name to which is added the termination ara.

Ex. 7. ×Sophrolaeliocattleya Hurst (in J. Roy. Hort. Soc. 21: 468. 1898) (Cattleya Lindl. × Laelia Lindl. × Sophronitis Lindl.); ×Rodrettiopsis Moir (in Orchid Rev. 84: ix. 1976) (Comparettia Poepp. & Endl. × Ionopsis Kunth × Rodriguezia Ruiz & Pav.); ×Holttumara Holttum (see Art. H.8 Ex. 3) (Arachnis Blume × Renanthera Lour. × Vanda W. Jones ex R. Br.).

Recommendation H.6A

H.6A.1. When a nothogeneric name is formed from the name of a person by adding the termination ara, that person should preferably be a collector, grower, or student of the group.
