Calyx 3- to 5-cleft. Petals 3 to 5, imbricate in the bud. Stamens twice 

 as many or rarely more, free or irregularly united at the base; anthers ovate 

 or oblong. Ovary 2- to 5-celled; style deciduous, with a capitate stigma; 

 ovules solitary or 2 in each cell, collateral or rarely superposed. BeiTy 

 globular, with a thickened rind, 1- to 5-seeded. Seeds obovoid or oblong, 

 testa membranous ; albumen none ; cotyledons flat or convex, more or less 

 fleshy. — -Shrubs or small trees, unarmed or thorny. Leaves simple, coriaceous, 

 riowers in axillary clusters or short racemes or small cymose panicles, occa- 

 sionally solitary. Pi-uils usually larger than in the preceding genera. 



The genus is dispersed over tropical Asia. The Australian species are both endemic ; one 

 however is in some measure doubtful, the flowers being unknown, and the other is slightly 

 anomalous in character though congener in essential points and babit. The genus, in the 

 increased number of stamens of two species, and in the infiorescence, fruit, and seeds, con- 

 nects the anomalous Citrus with the rest of the tribe. 



Leaves narrow. Spines straight or incurved. Pedicels clustered lu the 



axils of the leaves 1. A. glauca. 



Leaves ovate. Spines mostly recurred. Racemes short, axillary or tcr-

 glaucous shrub of 2 or 3 ft., often armed with straight or incurved axillary 

 spines of \ in. or under, the young shoots whitish with a very minute pu- 

 bescence. Leaves oblong-linear or slightly ouneate, very obtuse or emarginate, 

 mostly 1 to li- in. long, thick, rigid, veinless; narrowed into a short petiole; 

 those on the bairen shoots sometimes marked with a few coarse crenatures. 

 riowers usually 2 or 3 together in the axils, on pedicels of 1 to 2 lines. 

 Sepals 3 or 4, short and broad. Petals 3 or more frequently 4, obovate or 

 broadly oblong, 2 to 2^ lines long, thin, concave, much imbricate. Stamens 

 8 to 12, or sometimes more, the filaments often slightly united at the base. 

 Disk thick, annular. Ovary 4- or 5-celIed, with l,^or occasionally 3, super- 

 posed ovules m each cell. Style rather tliick. Berry globular, about \ in.
