ORDER XXXIX. AURANTIACEA,, Corr. 
(By W. H. Harvey.) 
(Aurantiacer, Corr. Ann. Mus. 1805.—DC. Prod. 1. p. 536. Endl. 
Gen, No. cexxiv. Lindl. Veg. Kingd. No. 457.) 
Flowers mostly perfect, regular. Calyz free, very short, 4~5 toothed 
or sub-entire. Petals 4-5 (very rarely but 3), broad at base, free or 
slightly cohering below, erect or spreading, deciduous, slightly or 
strongly imbricating in the bud. Stamens hypogynous, as many or 
twice as many as the petals, or a higher multiple of them ; filaments 
free or connate, flat, tapering ; anthers introrse, terminal or fixed at back. 
Ovary on a short, fleshy stipe, often surrounded by a crenulate disc, 5 
or many celled ; ovules solitary or in pairs, or numerous, pendulous, 
anatropous. Style terminal, simple, thick ; stigma obsoletely lobed. 
Fruit pulpy, indehiscent, with a leathery rind, 1 or several-celled. Seeds 
with a membranous coat, and very distinct raphe and chalaza, exalbu- 
minous ; embryo straight, cotyledons thick and fleshy, radicle short. _ 
_ Trees or shrubs, chiefly of the Eastern Continents, everywhere sprinkled with pel- 
lucid dots, filled with a strong-scented, essential oil. Leaves alternate, impari-pin- 
nate, sometimes reduced to a single terminal leaflet. Stipules none. Branches often 
thorny, Flowers white, and sweetly scented. The genus Citrus, the type of this 
Order, includes the various species and sub-species of orange, lemon, citron, lime, 
shaddock, &c. now commonly cultivated in all warm countries of both hemispheres. 
Lime-juice, containing a large per centage of citric acid, is an invaluable preventive 
of scurvy, in long voyages.

_ Calyx minute, 4-parted. Petals 4, concave, free, spreading, imbricate 
in the bud. Stamens 8, lypogynous, equal; filaments free, from a 
thickened base, subulate; anthers sagittate, incumbent. Ovary raised 
on a cylindrical, fleshy torus, obtusely 3-lobed, 3-celled ; ovules two 0 
each cell, axile, collateral ; style short, thick, deciduous ; stigma 3-lobed. 
Berry thinly fleshy, abortively 1-2 seeded. Presi. Bot. Bem. p. soul

a, but the ovules are collateral, not superimposed. The name is an anagram 
of Amyris. The genus was first indicated and characterized, but not named, by
