The venation is pinnate and closed. The leaf is simple but has some irregular shapes at the base. What do you call this leaf shape and margin? Lacerate? Laciniate?

I roughly traced one leaf.

Curious to know what tree this is.

I would call it a deltoid leaf that was coarsely toothed. If you're interested, this site has some good information on leaf types, shapes, and flower forms.

If you are anywhere near Portland cut a sample of a fruiting branch, put it in a cup or jar of water, set it up in the car so it is stable and take it to this place, ask for the owner (who will hopefully be there at the time - you might email or call ahead first, describe what you are trying to accomplish). Sean is an international level plant expert who may immediately know exactly what your shrub is. Even if you have to make a day trip out of it to get there, if you are dying to get a name for the plant it may be worth it to you.

And the nursery is an interesting place to visit anyway, one of a handful of operations of its type in the region.

The leaves are not pinnately compound. There are no leaflets set along a petiole, just simple leaves along a stem. I don't mean to nit pick but for id purposes the difference is relevant.

Could you also take an in focus closeup of those berries? Are they hard or soft? What's in a cross section when cut?

It looks like some kind of Viburnum to me.

Here are two close-ups of the berries. They are soft, and the inside pulp is purple.

I asked a botanist friend and he believes it is Premna, member of Verbenaceae.

Here's a species that has similar foliage. Premna microphylla

Here's a bit of conversation taken from a bonsai forum about the above species.

I was given a seedling to play around with last month. I can't bring
myself to work on it. It's smell is pretty strong and indescribable. It
is almost too stinky to stand, It does keep insects away,

I think Carol's friend is right about Premna. It seems it is now classified as Lamiaceae. It is also called Premna japonica. I found many Japanese pages with photos. They say that the young leaves have coarsely toothed margin but as they grow older, they become smoother. The Japanese name "hamakusagi" for Premna japonica is literally "beach stinky tree" because they are found near beaches and they are stinky!

Here are some photos.

Thanks for introducing me to a new plant. Strangely, I felt that it gave off a seaside vibe right from the start. It looked as if it would enjoy salt air with those fleshy leaves and judging by the green stems would need a mild climate.

Yay! It is clearly a Premna and thanks for your help on the species, too. Carol and marinaka, you are great plant sleuths!
