We therefore prefer to leave both the third and the fourth associations as nomina nuda while awaiting more data, as we have no personal experience of this type of vegetation in this territory.
Some proposed alliance names for groups of peatland associations must also be considered as nomina nuda and rejected according to ICPN specifications:
In group 3 we recognize two clearly differentiated associations, although we include another two in Table 2, as nomina nuda, whose identity requires careful study.
Stat rosa pristina nomine, nomina nuda
tenemus: yesterday's rose endures in its name; we hold empty names (Haft 176).
The purpose of this study is to bring the whole aspect on problematical names of spiders caused by Kishida's treatment to light by providing: 1) his personal history and a character sketch, 2) a list of his publications on spiders, 3) a list of spider taxa named by him, 4) a list of valid names extracted from these, 5) a list of nomina nuda, and 6) information on type specimens.
Valid names as well as remaining nomina nuda are herein listed.
Therefore, many nomina nuda exist, while some were described by other researchers.
but a few italicized species-group names are nomina nuda
, thus unavailable in terms of zoological nomenclature.
