Which Euphorbia are dioiceous?
Euphorbia obesa is a dioiceous species, which means that male and female flowers occur in separate plants (there are male plants and female plants).
Are there other dioiceous species in Euphorbia?
Where can I find this info?
I am particularly curious about E. stellispina , E. corrida, E. inermis and E. schoenlandii.
So any info about these species would also be great.
Thanks in advance

E. bupleurifolia. I believe this one can even change sex. One of my plants have done so, if I remembered well. They don't flower easily for me, and I don't have this particular plant anymore to check up on this in future flowerings, unfortunately.

Euphorbia stellispina is definitely dioecious.

Re: Which Euphorbia are dioiceous?
Thank you Aiko.
E. bupleurifolia is in the dream list...what a beautiful species! Interesting this about changing sex...
Do you have the species I mentioned above? Are all they monoicous? Thank you again

Re: Which Euphorbia are dioiceous?
Thank you Aloinopsis! I have five of that and considering swap one with a friend (he would give me an E. knuthii). I was afraid to end up with only males or females.
They are flowering already (the stellispinas) but I have never tried to pollinate them...maybe I should...(any tips?).
Thank you!

Re: Which Euphorbia are dioiceous?
I pollinate all of my Euphorbias with forceps. I just pluck the male cyathia completely off and rub it gently on the female cyathia.
I don't use a brush anymore because they don't produce much pollen to begin with, and a brush always manages to retain some of it.
I have also found that by plucking off the entire male cyathia it usually stimulates the plant to produce another one whereas using a brush to take only the pollen itself may not.

Interesting. I think I must start with knowing to recognize male and female cyathia...Aloinopsis wrote: ↑Sat Jul 06, 2019 10:48 am I pollinate all of my Euphorbias with forceps. I just pluck the male cyathia completely off and rub it gently on the female cyathia.

Re: Which Euphorbia are dioiceous?
Here are a couple of my obesa examples.
Most of them look pretty similar across species. It's easier to compare them when you have both right in front of you.
Females have 3 "little yellow things" Each of which will turn into a seed if it is fertilized. Males have a lot of "tiny yellow things."
Males' sexual parts are more loosely attached because they fall off a lot sooner (ouch!) but females stay on for weeks or months as they ripen.

Re: Which Euphorbia are dioiceous?
You're welcome! It's one of those things that seems simple but if you don't have plants right beside you to compare, it can get kind of confusing.
I have actually heard of rare male Euphorbia obesa that have occassional female flowers and are receptive to other males' pollen (gynodioecy) but I have never seen it first-hand.

Frank Vincentz's site should be useful: www.euphorbia.de.
I believe my E. tubiglans changed sex too but I have not successfully hand-pollinated my Euphorbias thus far![sad :(](./images/smilies/icon_frown.gif)
