Beilschmiedia obtusifolia is a rainforest laurel growing in eastern Australia. The range of natural distribution is from the Manning River (31° S) in New South Wales to the Daintree River (16° S) in tropical Queensland. Beilschmiedia obtusifolia grows in tropical and sub tropical rainforests. Usually on the more fertile basaltic sites, sometimes close to the sea. Common names include Blush Walnut, Hard Bolly Gum, and Nut Wood.[2]
Description
A medium to large tree reaching to 37 metres tall[3] and one metre in trunk diameter. The cylindrical trunk is brown or creamy with vertical lines of raised pustules. The trunk features scales with round depressions, colloquially known as "bollies", similar to the related Bollygum, Litsea reticulata. The tree's base is flanged in larger specimens.
Shoots and stems hairy. The elliptic or reverse lanceolate shaped leaves are alternate and not toothed, 8 to 10 cm long and 2 to 4 cm wide. Bluntly pointed or sometimes notched at the tip. Leaf stalks 5 mm long. Leaf venation is prominent on both sides, with a raised midrib.
Cream flowers form in panicles from October to November, the flowers have an unpleasant scent. The fruit ripens December to July, being a black egg shaped drupe with a scented green oily aril. 20 to 30 mm long with a single seed inside. As with most Australian laurels, removal of the fleshy aril is advised to assist seed germination, which is slow but fairly reliable with Beilschmiedia obtusifolia.
The fruit is eaten by a variety of birds, including Rose-crowned Fruit Dove, Topknot Pigeon, Green Catbird and the Wompoo Fruit Dove.
