of equal or double rarely threefold, in Huegelia manifold, number with the petals, some¬ 
times alternately sterile, inserted on the outer side of a hypogynous rarely perigynous 
disk, free or rarely coherent or actuate to the base of the petals. Anthers two-celled, 
with introrse longitudinal dehiscence. Styles united into one or rarely from below 
the apex free. Stigma simple or several united into one. Ovaries 2-5, coherent, 
one-celled. Ovules 2 in juxtaposition or one above the other, rarely 1, 4 or more. 
Carpels 2-5, bivalved. Undo carp cartilaginous, separating from the sarcocarp, rarely 
permanently actuate. Seeds with or without albumen. Testa crustaceous rarely 
bony. Cotyledons various. Radicle superior. 
Odorous shrubs, rarely trees or suffruticose plants, dotted with oil-glands, often 
exuding resinous secretions, very seldom climbing or thorny, abundant in South 
Africa and extratropical Australia, less common in tropical America, rare in the 
warmer parts of Asia, North Africa, tropical Australia and South Europe. Leaves 
without stipules, alternate or opposite, simple or compound. Disposition of flowers 
various. Petals white, yellow, purple or red, seldom blue, very rarely purplish-black. 
Endocarp bivalved.— Lindl. Veg. Kingd. 469. 
The relationship of Rutaceae to Xanthoxylese, Aurantiaceae and Zygophyllese is 
close in the extreme. 
The lovely plants constituting this order are, wherever they occur, an ornament 
of the flora. Beauty and rarity are in an unusual degree blended in this family, many 
species having a very circumscribed range of distribution. In addition to the genera 
mentioned in the subsequent pages Huegelia and Empleurosma are to be regarded as 
Australian Rutaceae, on the authority of Robert Brown and Bartling. Huegelia trans¬ 
gresses far the usually assumed boundaries of the order by producing ten sepals, ten 
petals and indefinite perigynous stamens, the latter note suggesting an approach to 
Myrtacese. Empleurosma is not less abnormal in declinous apetalous flowers, notes 
Avhich may draw this plant perhaps into the vicinity of Dodoncea. Anthoderris, 
indicated by A. Cunningham in the appendix to the Narrative of King’s Survey, pp. 
22 and 23, and named in Hooker’s Journal, is referable to Verticordia, an opinion 
confirmed by Mr. Robert Heward. An habitual resemblance exists in some Australian 
Rutaceae, for instance, Chorilaena to Buettneriacese through Corethrostylis and Se- 
ringea, whilst no less a similarity is manifest to Tremandrese. 
Most valuable information on the Rutaceous plants may be sought in a learned 
essay promulgated by Adrien de Jussieu, in volume xii. of the Memoires du Museum 
d’Histoire Naturelle, in 1825. Since that period, however, the access of species to 
the order, gained by later discoveries, has been so great as to subject some of the 
generic limits then adopted to considerable alteration. Many of the indigenous 
Rutaceae possess diuretic and diaphoretic properties alike to those of the South 
African Bucco bush.
