1955 M. E. D. Poore in Jrnl. Ecol. 43 243 The additional term Nodum has been introduced to apply to an abstract unit [of vegetation]..of uncertain status. It corresponds to the term Taxon in systematics.

1955 M. E. D. Poore in Jrnl. Ecol. 43 259 Both the Rhacomitrium-Carex bigelowii and the Nardus noda..are clearly defined communities.

1961 Watsonia 5 76 The nodum is only developed on south- to west-facing slopes of 10 to 15°, fully exposed to wind and salt spray.

1971 New Phytologist 70 1155 The noda are related to environmental factors.

1973 H. J. B. Birks Past & Present Vegetation of Skye 25/2 Where the vegetational unit is rather heterogeneous, it is termed a nodum. The word is italicised when it is used to refer to a specific vegetational unit that does not merit the rank of association.

1998 Plant Ecol. 137 79 The vegetation can be divided into four discrete noda that correspond to different topographic positions..: nodum of Stipa trichotoma + St. tenuissima, nodum of Distichlis scoparia, [etc.].
