Answers
Answer:
Datura belongs to the family solanaceae
The inflorescence is solitary cyme
Exstipulate leaves with unicostate reticulate venation.alternate phyllotaxy
Solitary auxillary cyme
Flowers are bracteate pedicillate complete bisexual pentamerous hypogynous and actinomprphic tending towards zygomorphic
5epals gamosepalous with salvage activation calyx persistent
5petals sympetalous plicate with twisted aestivation
Stamens 5 free epipetlous alternipetlaous basifixed anthers introse and longitudinal dehiscence
Bicarpilaary syncarpous
superior ovary with swollen axile placentation .Binocular but due to the development of false septum becomes tetralocular.
Style simple and long and stigma bilobed
Calotropis belongs to the family Asclepidaceae
Stem contains latex
Leaves are sessile exstipulate opposite decussate phyllotaxy covered with wollen tomentum with unicostate reticulate venation
Inflorescence is Umbelliform cyme
Flowers bracteate pedicillate bisexual actinomorphic and hypogynous
Five sepals free imbricate aestivation
Five gamosepalous vavate aestivation
Stamens 5 epipetalous monoadlephous stamina fused with pentangular stigmatic disc to form gynostegium.anthers dithecous coherent with stigmatic disc.
Mature anther lobe has single pollen mass of pollinium hence two pollinia so 5 anthers have 10 pollinia Anther lobes connected with caudices and united at splint called corpusculum.The corpusculum is sticking to the angle if gynostegium .The whole mechanism consisting of 2 pollinia2 caudices and a corpusculam constitute the translator
Corona is staminalconsists of 5 fleshy appendages adnate to the radiating from the staminal tube .The lower end is free
Gynoecium .bicarpellary apocorpous unilicular superior ovary marginal placentation stigma fused to form pentangular disc with which anther lobes and filaments of stamens fused to form gynostegium
Note - solitary cyme in Datura which is umbelloid cyme in Calotrophis
Leaves are in alternate phyllotaxy which is opposite decussate in Calotrophis
Flowers are actinomorphic but tending towards zygomorphic due to oblique orientation of carpels which is actinomorphic in calotrophis
Persistent calyx in Datura but not in Calotrophis
Stamens free and epipetalous in Datura but in Calotrophis it is monoadlephous .Stigma fused with it to form gynostegium
Anthers are free in Datura but in Calotrophis united to form called corpusculum .Each anther becomes pollinum in Calotrophis
In Datura the gynoecium is bicarpellary syncarpous binocular with swollen axile placentation .Whereas in Calotrophis it is bicarpellary apocarpous unilocular with marginal placentation
Stigma is free in Datura and it is gynostemium in Calotrophis
