This depends from which perspective you are talking. If you are talking about it from a database/relationship point of view then - No. Not every Species entry is going to have a Cultivar name. I.e. you can use plain old Acer Palmatum which is just Genus/Species and no cultivar. However, if you are looking at it from a botanical point of view then it is quite likely the the majority of Species will have a Cultivar also. Please note that when saying Cultivar, for the simplicity of the database it should be assumed to include Cultivar, F., Var. Subsp etc. but Species should be read to include x (e.g. Lonicera (Genus) x purpusii (Species)
This is not strictly true in real life but will be good enough for the purpose of the Database.
Cheers
Rowan
