Here are some photos of my Monachello (?) foliage, buds, and leaves. Tree (large bush at about 12 feet height) growing on own it’s roots. It was essentially 6-trunked (due to a prior freeze) then another bad freeze took it down to the ground and regrowth resulted in many more trunks (over 1 dozen now). Suckers readily. Growth is rapid (1’ per flush or more). Repeat blooms, but only one (or none) fruit per flower cluster due to aborted ovaries in most buds (functionally male). Some thorns, but mostly small. Strong lemon/citron smell to leaves when crushed. Fruit tart and good lemon flavor. I will look for old photo of ripe fruit.
