Genera Included: Mida Cunn. ex Endl., Nanodea Banks ex Gaertner f.
Habit: Mida is a root parasitic tree (to 6 m) and Nanodea is a turf- or mat-forming dwarf shrub
Parasitism: Documented in Mida (Philipson 1959) and Nanodea (Skottsberg 1913).
Stem: branches glabrous in both genera. In Mida the bark is smooth, grey to grey-black and the branchlets slender and brittle. In Nanodea the branches are filiform.
Wood Anatomy: Mida reported by Patel (1974).
Leaves: For Mida: alternate, sometimes with a few subopposite to opposite; petioles slender, short, somewhat fleshy; leaf shape varying tremendously (even on same individual), including linear, narrow-lanceolate, ovate to oblong-ovate, broad-elliptic to rhomboid; adaxial surface dark green to yellow green, very glossy, abaxial surface paler and mat; apex acute, subacuminate to acuminate; texture of blade papery, membranous or semi-coriaceous; margins entire, sinuate or distinctly scalloped. For Nanodea: alternate, scattered, glabrous, somewhat thick, linear with acute apex, 1 x 0.1 cm.
Inflorescence: Mida inflorescences are axillary, few-flowered racemes whereas in Nanodea the flowers occur one per leaf axil, often in clusters of 2-3 flowers at the stem apex. Floral bracts and/or bracteoles persistent, separate.
Plant Sex: Mida is gynodioecious whereas Nanodea flowers are bisexual.
Flowers: Mida is
pedicellate whereas Nanodea
the flowers are nearly sessile.
Fruit: pseudodrupe, with parenchymatous epicarp and endocarp and a stony or woody mesocarp. Mature fruit crowned by persistent perianth parts. Bracts persistent at base of fruit in Nanodea.
Seed: One per fruit, enclosed in woody endocarp.
Chromosomes: Mida 2n = 66 (as reported on NZ Plant Conservation Network website).
Alternate Family Names: none
