Cryptocarya macklinnoiana

Mackinnon's Laurel

Flowering usually occurs between October–May
The form of the flowers is paniculate and located beyond the leaves whilst their perfume has been often described as unpleasant
The perianth tube's inner surface is pubescent whilst the tepals are approximately 1.1-1.9 mm long and feature an outer surface which is also pubescent
The ovary usually has no hairs but is occasionally pubescent whilst the style is glabrous

Fruit:

The fruits feature spots with small pustules that usually have a form which is ellipsoid but can occasionally be more ovoid or obpyriform
The fruits are 19-28 x 13-17 mm in size with cotyledons that range from creamy to yellowish
The fruit are eaten by many bird species and native rat

Leaves:

The leaf blades have dimensions ranging from approximately 13-35 x 4.5-8.5 cm and have a slight glaucous layer underneath along with hairs which are tortuous, brown in colour and erect
On their upper surface the leaves have a depressed midrib and petioles which can be ridged, flat or channelled
On the underside of the leaf blade reticulate veins are raised in a pronounced manner which forms a well defined network

Stem & branches:

Growing up to 25m in size
The stem has a thin creamy to pale brownish coloured layer which can usually be seen under the subrhytidome layer just outside of the stem's outer blaze
The twigs feature fluted grooves with a dense mixture of different hairs, the longer ones are tortuous whilst the shorter hairs have a more papillate form
The hairs range in colour from dark brown through to pale brown and usually sit erect and can remain on twigs which are quite old
