obdiplostemonous, a. Bot.|ɒbdɪpləʊˈstiːmənəs|
[See ob- 2.]
Diplostemonous with the disposition of the two stamen-whorls reversed; having the stamens of the outer whorl opposite to, and those of the inner whorl alternate with, the petals. Hence obdiploˈstemony, the condition of being obdiplostemonous.
1880Gray 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. 1882Nature 7 Dec. 126 The..curious ‘obdiplostemonous’ arrangement in the..genus Platytheca. 1888Henslow 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. |
