Definitions are strange things, sometimes. Take flowers. Perfect flowers. Like a rose.
Perfect flowers are flowers that include both male and female parts within a single flower. Imperfect flowers are flowers that have only male or only female parts.
A complete flower contains sepals, petals, pistils, and stamens. An incomplete flower is missing one of those parts.
Incomplete flowers can be perfect or imperfect flowers. Perfect incomplete flowers have both stamen and a pistil present on the same flower, but lack sepals or petals. Imperfect incomplete flowers lack either the stamen or the pistil on the same flower but have sepals and petals. (Study.com)
So what is this one?
False bugbane,Trautvetteria caroliniensis. |
This flower has no petals. Where we expect to see petals, it has from 50 to 100 stamens, the male organs. And there are 15 pistils, the female parts, so that makes it a perfect flower. But incomplete.
Nootka rose, rosa nutkana. |
The rose, whether it's a wild rose, with its 5 petals, or one in your garden, with up to 40, is perfect and complete. It has petals, sepals, stamens, and pistils.
False lily-of-the-valley, Maianthemum dilatatum. |
And these are both perfect and complete, too. Or maybe not. What looks like petals are tepals, which means they couldn't figure out whether they were sepals or petals. And a complete flower has both.

Las flores perfectas son flores que incluyen partes tanto masculinas como femeninas en una sola flor. Flores imperfectas son flores que tienen solamente partes masculinas o partes femeninas.Una flor completa contiene sépalos y pétalos, pistilos y estambres. A una flor incompleta le falta una de esas partes.Una flor incompleta puede ser perfecta o imperfecta. Flores perfectas pero incompletas tienen tanto el estambre como un pistilo en la misma flor, pero le faltan o los pétalos o los sépalos. A las flores incompletas e imperfectas les falta o el estambre o el pistilo en la misma flor, pero tienen los pétalos y sépalos. (Study.com)
- Y esta, entonces, ¿qué es? Trautvetteria caroliniensis. Esta flor no tiene pétalos. Donde esperamos ver los pétalos, se encuentran los estambres, desde 50 a 100 estambres, los órganos masculinos. Y hay 15 pistilos, que son femeninos, lo que hace que la flor sea una flor perfecta. Pero incompleta.
- La rosa, sea una rosa silvestre con sus 5 pétalos, o una en tu jardín, con hasta 40 pétalos, es perfecta y completa. Tiene los sépalos, los pétalos, los estambres, y los pistilos.
- Y estas, Maiathemum dilatatum, el falso lirio de los valles, también son perfectas. ¿Completas? Tal vez no lo son. Lo que parece ser pétalos, son tépalos, lo que quiere decir que no pudieron decidir si eran pétalos o sépalos. Y una flor completa tiene que tener ambos.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.
Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
