Plant of the Month: What’s in the Box?

Flora, Latest Newsletter, Plant Nerd, Plant of the Month, The Scoop

This month I’m back to our rather slow series of keys to the Eucalypts of the Hunter. if you’ve missed (or forgotten) I’ve previously done keys to Ironbarks, Scribbly Gums, Mallees, Bloodwoods (Corymbia) and the Apples (Angophora).

This month we’re looking at the Boxes, so named because their short fibrous bark is reminiscent of the European Box (Buxus), most of the boxes occur in the upper Hunter with only the Grey Box (Eucalyptus moluccana) and Rudder’s Box (E. rudderi) finding it’s way to the lower Hunter.

As with most things related to the natural world there are some exceptions, Slaty Box has a smooth bark and is not included here and Yellow Box can be quite variable. Bimble Box (Eucalyptus populnea) is also not included as I’ve only been able to find two specimens (a mature tree Wybong and a sapling at Gungal) and has only been collected twice from the Hunter, once in a planting and once by JL Boorman in 1904.

Differentiation between White and Grey Box in the Upper Hunter is a source of constant frustration for many of us, I generally find Murrurundi to Moonan Flat it’s usually White Box, east of Denman Grey Box and the Merriwa plateau is often hybrids (there’s also a lot of Fuzzy Box around Merriwa to Martindale).
