coriaceous testa ; albumen none ; embryos often more than one ; cotyledons 

 fleshy, plano-convex.— Trees or shrubs, often armed with axillary spines. Leaves 

 l-foholate, the petiole often winged. Flowers white, axillary, solitary, clustered 

 or shortly paniculate. 



The really wild species are few, chiefly from tropical Asia, but long culture in most hot 

 countries- has produced numerous permanent varieties. The Australian ones differ from the 

 others m the short petiole not at all vmged.—Benth.

 Amtr. i. 371. Native Orange; " Dooja," Taromeo, Shirleij. A tree of 30 to 

 over 60ft., quite glabrous, with axillary straight thorns of about |in. Leaves 

 ovate, obovate, or almost rhomboidal, 1 to 2in. long, obtuse or emarginate, the 

 petiole not exceeding 3 lines and not winged, very small and linear on young 

 plant. Flowers pinkish. Calyx teeth or sepals almost orbicular, about 1 line in 

 diameter, sometimes only 4. Petals 2^- lines or more long, oblong. Stamens 

 free, about 17, subulate. Ovary sulcate and including the style shorter than the 

 stamens. Stigma large. Fruit globular, from 1 to 2^in. diameter, with a rough 

 rind ; cells 6 to 8, more or less pulpy, with usually 3 or 4 seeds in each. —

Hab.: Coast scrubs of southern Queensland. 



Wood of a light-yellow, close-grained, hard and durable ; useful for cabinet-work and might 

 probably serve for engraving. The fruit useful for preserves. — Bailey's Cat. Ql. Woods No. 55. 



2. C. australasica (Australian), F. v. M. Fragm. i. 26 ; Benth. Fl. Austr. i. 

 371. Finger Lime. A tall shrub or small tree, quite glabrous, with axillary straight 

 slender spines of ^in. or less. Leaves from obovate-oblong to oblong-cuneate 

 or lanceolate, very obtuse and emarginate, 1 to 1-J or rarely 2in. long, coriaceous, 

 the petiole usually very short, and not winged. Flowers solitary or rarely 2 

 together, on very short pedicels. Sepals 5, small, spreading, concave, minutely 

 ciliate. Petals oblong, nearly 4 lines long. Stamens 20 to 25, free. Ovary in 

 the flowers examined 6-oelled. Style very short, with a thickened, obtuse, 

 furrowed stigma. Ovules 4 in each cell. Fruit oblong, almost cylindrical, 2 or 

 3 times as long as broad, the largest seen about 4in> long, with usually 2 or 3 

 seeds in each cell. 



Hab.: Mountain scrubs of southern Queensland. 



Wood close-grained, of a yellowish colour. Fruit of each variety makes excellent preserve. —

Var. sanguinea, Bail. Red-fruited Finger Lime. This differs from the ordinary form in 

 colour of fruit only. This, however, being constant, it is better that the form should be known 

 by a distinctive name. The fruit attains about 2 or 3in. in length and fin. diameter, is of a 

 blood-red colour, thin-skinned, pulp sharply acid, and of a pink colour. Hab.: Tambourine 

 Mountain, J. Pindar. 



3. C. inodora (inodorous). Bail. Rep. Bot. Bellenden Ker Exped. 1889. 

 North Queensland Lime. A tall shrub, the young branches flattened or more 

 or less angular as in the common orange. Spines not very numerous, about Jin. 

 long, erect, 1 or 2 at the axils of the leaf. Leaves lanceolate or ovate-lanceolate, 

 with distant sinuous crenations, 3 to 7in. long, IJ to 2in. broad in the centre, the 

 apex often elongated, and tapering towards the base to a very short petiole 

 seldom exceeding Jin. in length ; substance coriaceous ; midrib and primary veins 

 more or less prominent, the latter rather close and anastomosing in an intra- 

 marginal vein. Flowers axillary, nearly sessile, and, so far as observed, scentless. 

 Calyx of 5 minute teeth. Petals 5, about 8 lines long, spreading. Stamens
