Also, the earliest (and one of the best) depictions I've seen of an idealized water mouth 水口. 10th of 10 "great collapses": "observe the water mouth - its islets, temples, ponds, shrines, and groves, their state indicates the state of the village within..."

Just discovered hundreds of pages of geomantic texts in the Yongle dadian 永樂大典, including left "ghost of litigation and whipping followers" formation and right "ghost of temples of ill repute" formation.

How have I not wasted days on Michael Boym's Flora Sinensis yet?

Here are trees shading graves. Notional depictions from an early example (16th cent?) on the left. Clearer depictions of conifers in the later (late 19th cent) example on the right.

It's worth noting that individual trees are depicted in situations where they are clearly significant. To the left is a well 井 with a tree (camphor?) standing behind it. To the right is an old pond with three large trees (two pines? and ?) shading it.

What about these other trees? I can identify at least three, and possibly as many as five, other varieties, not counting the willows in the foreground and the sweetgum (?) at left. I suspect - again from fieldwork - that at least one of these is a camphor. Probably the small-leaved one in the middle

But what about this tree on the left? It is clearly depicted as having five-lobed leaves. Is it the same tree as the right (from 饮膳正要)? Fieldwork suggests that it might be Chinese sweetgum 楓香, which has five-lobed leaves and is often found in fengshui forests.

The tall trees by this pagoda (left) are clearly pines 松. Similar depictions of pines, are found, for example, in the 14th century pharmacopeia Yinshan zhengyao 饮膳正要 (aka "A Soup for the Khan," this a 1456 edition).

This, for example (left), is fairly clearly a willow 柳. This is confirmed by a print from the same volume titled "willows line the dikes with shade" (right) with nearly identical tree forms.

Here's a depiction of a water mouth 水口 from a 19th century genealogy. It's clear to me that images like this do not just depict "generic" trees - they depict specific trees that mattered to the fengshui of the landscape. Any suggestions on how to identify them? I've had only some success.
