Description from The Citrus Industry Vol. 1 (1967):

" Leaves broadly oval or lanceolate, or with cuneate bases and more or less acute or even caudate at the apex, 8-18 X 4-10 cm, with very numerous, parallel, lateral veins arising at an angle of 60°-80° with the midrib; petioles very short, 4-8 mm long, wingless, not articulated with the blade; flowers small (as in other species of Microcitrus) but reported by Bailey to be odorless; stamens free but much more numerous (over 30!) than in the other species of Microcitrus; fruit oblong or elliptical (somewhat lemon-shaped), 5-6.5 X 3-3.5 cm, with a conical base, segments 8, on drying sometimes showing ribs corresponding to the walls separating the segments; pulp-vesicles stalked like those of other species of Microcitrus, rather loose; seeds small, somewhat pear-shaped, 6-8 X 4-5 mm.
      This species is a shrub or small tree 2 to 4 meters high with the trunk 4 to 5 cm in diameter.   The twigs are angular like those of Citrus sinensis (the sweet orange) and have one or two slender, very sharp spines, 6 to 12 mm long.   It has been found growing wild only along Harvey's Creek, Russell River, where, according to White (l.c., p. 119), it is common in the lowland rain forests at the foot of the Bellenden-Ker Range in northern Queensland near Cairns (Lat. 17° S.).   This is a very rainy region, the average annual precipitation being 170 inches.   In February, 1922 (?), the rainfall was 62 inches! "
