Hi Jerry,
I just remembered your questions about Euphorbia back in October.
So I decided to get a closer look at some of my Euphorbias.
I find it quite interesting about the sexes of Euphorbia flowers. Some are single sex plant. Some have both male and female on the same plant, but flower at the different time, some at the same time. Some have both male and female flower on the same flower bud.
Below are a few of the examples:

Euphorbia baylissii, both male and female flower about the same time. Male on the centre, 2 females on the sides.

Euphorbia classenii. not sure which first, but you can see the seed pod with male flower on the side.

Euphorbia geroldii, an interesting one. The first picture is the male flower, which opened first, with no sign of female flower, then the second picture, after a week or so, 2 female flowers developed from the sides of the male flower (you can see the male flower still there).

Euphorbia pseudocactus, male flower first, then female flowers develop on the sides. Bottom 2 flowers are males, and 2 flowers on the top left are females.

Jatropha podagrica. 1st picture, males flowers and 2 seedpods (so, I think the female flowers must had developed first). 2nd picture, new flowers, females only, I think the smaller buds on the sides of female flowers, might develop into male flower, I will keep an eye on them.

Maybe my observations are not 100% right, but I think it is quite interesting. I will keep a closer observation on the flowers of Euphorbias and related species in future.

Thanks for the reply Bryan. And thanks for the photos. I just went over the photos I have of my plants over the years and selected a few to show you to see what your comments are about their flowers. A big question is: when are the flowers ready for pollination? I've seen people save pollen for use later. Do you know how this is done? What if the female blooms first?

This is one of my E. decaryi taken April 3, 2021 (our spring). I repotted all of my Euphorbia that year, right in the middle of flowering. Oh well.

I think the female flowers ready for pollination whenever its stigma is open.
I haven't try to collect Euphorbia flowers yet. A bit challenging because most of them are quite small, but can be done with small tweezers.
I use point tweezers to collect cactus pollen. Kept the pollen in Gelatin Capsules, then place them in the fridge. I learned that from Frank.
The pollen is variable up to about a month, depends on the species. So I assume Euphorbias should be about the same.
Here is the example of pollen I keep in the fridge.

From my observation, most Euphorbias continue to flower for a long period of time, so shouldn't be much problem no matter male or female flower first.
I am going to keep an eye on the few species you mentioned, they should be in flower at the moment. I will post the photos when they are available.
Just have to remember, Euphorbia seeds can't keep for too long, that's the reason why difficult to found Euphorbia seeds for sale.
Also, Euphorbia seedpods will explode when ripen, making it difficult to collect. This article will help.

Thanks Bryan. I have looked at this Euphorbia site and found a lot of helpful information. Here's their page on seeds, including how to catch them before they get scattered. Use the left hand pane to navigate. I use Google Translate so I can read it in English. https://www.euphorbia.de/seed.html

Sorry Jerry! The previous International Euphorbia Society website link doesn't work.
Here is it again. They have lots other information.

Ha, I saw the link didn't work and just copied it and pasted in a new page. It worked that way. I've been to that site before, and now I'm noticing some of the same content on both sites. Don't know who is the original poster.

Regarding hand pollination: If I have a plant that has both male and female flowers, the question is if the plant is self fertile. I have recently (last week) purchased two new E. decaryi that were produced from cuttings off of the same plant. I'm hoping my E. decaryi was not produced from the same plant as what I recently bought. There is about a 15 year time span between the two purchases, so I'm banking on them not being from the same plant.

I also just bought some E. tulearensis seed from Craig Fry. I plan on sowing it tomorrow. I'll use a heat mat and a strong LED light over them.
