NATURAL AND ARTIFICIAL HYBRID 
GENERIC NAMES OF ORCHIDS 
SUPPLEMENT IL: 1966-1969 
BY 
LEsLIE A. GARAY AND HERMAN R. SWEET 
Since the publication of the first compendium of ‘‘Nat- 
ural and Artificial Hybrid Generic Names of Orchids, 
1887-1965°’, in the Botanical Museum Leaflets, volume 
21: 141-212, 1966, we have uncovered several previously 
unrecorded names in addition to those which have been 
published for the first time during the intervening period. 
These names, together with corrections and supplemen- 
tary information, are included in this Supplement. Since 
hybrid generic names are not recorded in Index Kewen- 
sis, the first compendium and this supplement provide a 
similar tool for the interested orchidophiles. ‘To increase 
its usefulness, each hybrid generic name is evaluated and 
treated in accordance with the rules set forth in both the 
International Code of Botanical Nomenclature and the 
International Code of Nomenclature for Cultivated 
Plants. Both of these codes derive their authority from 
the International Union of Biological Sciences. 
In this Supplement, as in the first compendium, the 
rule of priority is strictly observed, an action most im- 
portant if stabilization in orchid nomenclature is to be 
achieved. Along this line, we have noted the acceptance 
of some necessary changes by the Orchid Registration
