Bailey, F.M. (1905) Queensland Agricultural Journal 15: 491. Type: Summit of Mount White, Cape York Peninsula, altitude about 1,300 ft., R.W. Garraway, May 1904.

Common name

Mount White Lime


Seldom exceeding 30 cm dbh. Lenticels about 10 cm long, narrow. Darker fibrous stripes and pale, granular stripes in the outer blaze. Blaze finely layered.


Oil dots large and numerous. Leaf blades about 2.5-5 x 1-3.5 cm. Leafy twigs often prickly.


Petals glabrous, about 7-8 x 3 mm. Stamens about 15, staminal filaments about 4-5 mm long. Disk small, at the base of the ovary, inside the whorl of staminal filaments.


Fruits +/- cylindrical, 7-10 x 2.5-3.5 cm. Surface rugose from large oil glands below the epidermis. Juice vesicles hard and tough, much harder and tougher than cultivated citrus (Citrus spp.) varieties.


A few cataphylls are produced before the first true leaves. First true leaves obovate, margins crenate, oil dots readily visible with a lens. At the tenth leaf stage: leaf blade obovate, margin crenate in the apical half, glabrous; oil dots numerous, just or almost visible to the naked eye; a single thorn present in the axil of each leaf. Seed germination time 18 to 37 days.
