| | Myrtales |
 | | Polyderm (alternating endodermal and parenchymatous layers laid down by a pericyclic meristem) is known from families like Onagraceae, Lythraceae, Myrtaceae, and probably Penaeaceae and Oliniaceae, at least (Mylius 1913). |
| | Tracheoidal sclereids with spiral wall thickenings that are associated with the vein endings are known from Vochysiaceae, Lythraceae, Combretaceae, Melastomataceae, Alzateaceae and Penaeaceae (Sajo and Rudall 2002); their more general distribution needs to be checked. |
| | Combretaceae may not be very easy to recognise, although like other Myrtales they often have opposite leaves and the bark is often flaking. |
