there has been astrict adherence to the requirements of 
the Codes, especially Articles 40, H. 8 and H. 4 of the 
International Code of Botanical Nomenclature. The in- 
terpretation of these articles was clearly explained in the 
introduction to the first compendium, the correctness of 
which is confirmed by ‘‘An Annotated Glossary of Bo- 
tanical Nomenclature’’, prepared on the authorization 
of the Nomenclature Section of the X. International 
Botanical Congress, in 1964. In this glossary on page 
14, under the term ‘‘Formula’’, we find the following 
statement: ‘‘Condensed formulae formed from parts of 
generic names and applied to intergeneric hybrids are 
treated as ‘generic names’ (Arts. H. 3, H. 4) and are 
subject to the rule of priority and the homonym rule.” 
In a few eases, it was discovered that certain names 
had appeared in publications earlier than those which 
were cited in the original list. These corrections are in- 
cluded in this Supplement in Part I, and, as indicated, 
they replace the earlier entries. ‘The citation of place of 
publication for the following names have been corrected: 
Grammatocymbidium, Gymnaplatanthera, Spatho- 
phaius, Symphodontioda, Symphodontoglossum, 
Symphyglossonia and Zygostylis. 
Hybrids reported for the first time for previously pub- 
lished hybrid generic names include, Grammatocym- 
bidium, Renaglottis and Renancentrum. 
Finally, attention is called to the arrangement of 
parent genera in Part II of this Supplement. The ge- 
neric names involved in the makeup of a given hybrid 
genus appear in alphabetical sequence only once under 
each name.
