Tubiflorae is a botanical name, meaning “with tubular flowers”. It was used in the Engler system (and derived systems such as the Wettstein system) for:

• an order in the Sympetalae. This order included such families as Convolvulaceae, Boraginaceae, Scrophulariaceae, Solanaceae, etc.^[1] This order does not correspond closely to any one group in the Cronquist system or in the APG II-system, but the component taxa belong in the Lamiales, Scrophulariales and Solanales of the Cronquist system and the euasterids I of the APG II-system.
• a subfamily in the family Compositae (as opposed to the subfamily Liguliflorae).

Note that these days the rules for botanical nomenclature, the ICBN, allow such descriptive botanical names only at a rank above that of family, so that Tubiflorae is allowed as the name of an order, but not as that of a subfamily.
