Catkin inflorescence is pendulous i.e, hanging whereas spadix inflorescence is mostly upright.
Catkin Inflorescence is not covered by spathe whereas spadix inflorescence is covered by spathe.
In catkin inflorescence male and female flowers are present on different catkins whereas in spadix inflorescence male and female flowers may be present on same spadix or on different spadices.
In catkin inflorescence whole peduncle is fertile whereas in spadix inflorescence apical part of peduncle is sterile i.e flowerless and is called appendix.
In catkin inflorescence there is nothing special to attract the pollinators whereas in spadix inflorescence spathe and appendix are coloured which attract the pollinators.
