Narrative

Additional Weather Notes: June to Sept. rainfall accounts for 70% of the average total yearly rainfall. Sometimes there are spring droughts. Sometimes there is hail, low temp. and frost in fall. There also can be fall waterlogging of the soil. Sampled average 54 M. zhaojiaoensis fruit from 11 trees, and 15 M. prattii fruit from 1 tree. Trees had few fruit, elongate, persistant calyx, varied size. Some leaf spotting. Oldest tree was 80-100 yrs old. Pop: over 50; very scattered dist.
