If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|N. L. Baghai 1988||Carpels are winged, with a narrow to acute apex, 1.6-3.4 cm long. Wings are broadly lanceolate with parallel margins, 1.1-2.6 cm long, 0.5-0.7 cm wide. The wings have a distinct midrib. Two or three basally departing secondaries are subparallel to the midrib and fork once or twice. Minute bands of sclerotic tissues are present between the veins.
