| 2 | Ovules 4 or more in each carpel. The hair base replaces a normal epidermal cell, so that the loss of a hair leaves a pore in the cutical membrane. Leaf anatomical characters: sclerified epidermal and hypodermal layers, sclerified arm parenchyma in the mesophyll, unlignified vein-sheath cells, absence of either sclerified veinlet terminal cells or a sclerified leaf margin |
| 2' | Ovules 2 in each carpel (4 in Magnolia kachirachirai), sometimes 4 in the lower carpels. The hair base consists of at least two epidermal cells. The hair does not leave a pore when falling |
