Help finding a research article on a specific area of tree morphology

[pigwot]

Help: I can’t seem to find this article (and I’m fairly sure it wasn’t a dream )…

“Species-specific, unique scaffold limb radial divergence angle (included-angle from bole)”.

Back in about 1989 to 1991 there was a research article with birds-eye views of a number of different tree species showing how different trees maximized their solar gain by having a specific, predictable radial branching distribution that related to their specific leaf morphology and leaf distribution on their secondary and tertiary branching. I thought it was a reprint in our Penn-Del chapter newsletter, but it might have been in Arbor Age…

Anyone know of such a research article?

Can’t help but if you find it post it here

I can see it in my memory; line drawings of trees viewed straight down, with typical included angles… I recycled years of arboriculture articles when I moved

This is staring to ring a bell. I’d think it’s in the first or second edition of Arborculture by Harris

Entirely off topic but fascinating.
