1880 A. Gray Struct. Bot. vi. §3. 198 It..occurs that the antipetalous stamens are more or less exterior in insertion, and then the carpels, when isomerous, are alternate with the inner and antisepalous stamens, and therefore opposite the petals... This arrangement takes the name of Obdiplostemony.
1888 G. Henslow Origin Floral Struct. xx. 189 In..most..genera..obdiplostemony..is..due to the petaline whorl of filaments being, so to say, thrust outside the level of the calycine whorl by the protruding..bases of the carpels.
1965 P. Bell & D. Coombe tr. Strasburger's Textbk. Bot. (new ed.) 623 Obdiplostemony occurs, e.g., in the Carophyllaceae and Crassulaceae.., but its meaning is uncertain.
