Key adapted from A.T.Hunziker in J.G.Hawkes et al., Linn. Soc. Symp. Ser. 7: 49–51 (1979)
1 Seeds prismatic, reniform or subglobose, or of a different form but
never discoidal-compressed subfam. 1. CESTROIDEAE

species); corolla actinomorphic or slightly zygomorphic; herbs,
rarely shrubs (Nicotiana, Nierembergia, Petunia) trib. 3. NICOTIANEAE

5 Aestivation valvate, induplicate, plicate or conduplicate (i.e., corolla
lobes never overlapping)
6 Filaments inserted generally near centre of anthers on dorsal face;
climber (Salpichroa) trib. 6. JABOROSEAE
6: Filaments inserted at or near base of anthers; herbs or shrubs

Treatment of infrafamilial taxa
Amended from Fl. Australia 29: 2 (1982)
For each infrafamilial taxon there is a centred heading followed by a line repeating the name
and giving the author and the reference to the place of original publication. The
nomenclatural type is also given. The subfamily Cestroideae and tribe Anthocercideae
provide examples.
Synonyms
Synonyms for infrafamilial names are included, within reason, with each beginning a new
line. Where the numbers of synonyms are excessive, only the more important and better
known are listed. A full list may be prepared for inclusion in the IOPI Checklist. If in doubt
consult the Executive Editor.
