I couple of years ago I bought a Osamanthus americanus and right now it is covered with fragrant blooms, but I don't know if it is a male or female. I also found a wild one growing in some woods and got cuttings from it, but I don't know if it's male or female either. Is there a way to tell?
Osmanthus - Male or Female??
Do the flowers have well-developed stamens, or a well-developed stigma?
Post a close-up macro pic if need be

Have you ever seen berries? If not, that may indicate that it's a male.
Looks like well-developed stamens there, so it's probably male. Don't completely lose hope of fruit though, as sex expression in Oleaceae species is often not 100% one or the other (and can also do odd things like change with time over a number of years).

I haven't seen any berries on mine, but I had always assumed it was because there wasn't a pollinator nearby. The wild one that I took cuttings from is about 5 miles away, I'm gonna try to get pics of it.
I agree with Resin's summary; those look like male flowers.
I'll be looking at the plants around here for ID of reproductive parts, and try to take as good a pic as E-Guy's.
Note: use the same method to determine sex of flowers on Ilex species.
Females are the only ones that fruit, on Ilex species too, so I just thought that might be easier. :0)
I went back and looked at that wild one but the flowers were so far away I couldn't get a good picture, and the thing was covered with poison ivy. What are the chances that my cuttings will take root? I have four of them in cups of potting soil inside of a ziplock bag. I treated them with rooting hormone first.
What are the chances that my cuttings will take root?
Should be fairly good. One of my books recommends late July, with bottom heat, for the best success.
Resin
I found these green berries today, so I'm assuming it's a female?
Yep, that's female. Is it the same plant as the one pictured before, or a different one?
Resin
It's the same one.
Just one branch with fruit on? I've heard of Fraxinus doing that (most of the tree one sex, with a single branch the other sex).
Resin
The fruit is scattered throughout the whole tree.
I just remembered, when I took those cuttings from the wild tree, some had flowers on them so I put one in my tree just in case it could cross pollinate. Ya think that one little cutting from the other tree could have pollinated mine?
Some info in the Flora of China: "Flowers bisexual, usually becoming unisexual and plants dioecious or androdioecious"

Looks like the sexuality of Osamanthus is fairly complex!
Resin
metrosexual? It's all the rage I guess.
Far too complex for me to figure out. LOL
I reckon I'll wait until fall and see if the fruit contains seeds, and if so, try to germinate some.
