 | | As defined by Cronquist (1988), Theaceae is a large taxon of a rather diverse membership that hangs together by their imbricate or convolute petals, typically solitary, lobed or cleft style, imbricate sepals, anthers that open primarily by longitudinal slits, and by the presence of bitegmic ovules. |
 | | The subfamily Asteropeioideae, with their strongly accrescent sepals that become winglike in fruit, axillary or terminal panicles, the 5 petals that adhere to the connate sepals, and 10 or rarely 15 stamens, are now usually treated at the family rank as Asteropeiaceae. |
 | | As a result, the Theaceae proper are those members with imbricate petals and non-accrescent sepals that form a capsule or a fleshy drupaceous fruit (Theoideae) or the fruit that is baccate or dry and indehiscent (Ternstroemioideae Burnett). |
