GEIJERA. 
Schott , Rutac. 7, t. iv. 
Calyx short, five-cleft, persistent; its lobes imbricate in aestivation. Petals 5, sessile, induplicate- 
valvate in praeflorescence, deciduous. Stamens 5, opposite to the lobes of the calyx. Filaments 
subulate. Anthers without appendage. Ovaries 5, surrounded by the slightly five-lobed disk, with 
a solitary pendulous ovule attached near the summit of the internal angle of the cavity. Style 
short. Stigma capitate. Carpels blunt. Endocarp very imperfectly separating from the coriaceous 
sarcocarp . Seeds ovate-globose. Testa bony. 
Evergreen shrubs and trees of extratropical and eastern tropical Australia, Branchlets unarmed. 
Leaves alternate, simple, coriaceous, entire. Panicles terminal. Pedicels minutely bracteolate. Flowers 
small, hermaphrodite. Petals almost white. Seeds sliining-black.— EndL Gen . 1154. 
Geijera effects the transit from Euodia to Xantlioxylon and Blackburnia ; from the former it is 
chiefly distinguished in simple alternate leaves and in but slightly seceding endocarp. From Black¬ 
burnia, of which one species (B. xanthoxyloides, F. M.) occurs near Moreton Bay, Geijera is easily 
recognized in having neither monoecious flowers, nor pinnate leaves, nor solitary ovaries ; it agrees, 
however, more with this genus than with any other amongst Xanthoxyleae, in the normally one-ovuled 
germens and the valvate praeflorescence of the corolla. Xanthoxylum, which numbers at least one 
legitimate representative in Eastern Australia (X. brachyacanthum, F. M.) differs in its pinnate leaves, 
imbricative praeflorescence of corolla, polygamous flov r ers and biovulate germens. Adr. de Jussieu 
mentions in the Memoires du Museum d'Histoire Naturelle, xii. 503 and 504, a West Australian 
Xanthoxylum, under the name of X. Australasieum, to which as indentical Eriostemon linearifolius 
(Cand. Prodr. i. 720) is quoted. This plant, notwithstanding it is stated to have biovulate carpels, 
which is an exceptional character in Geijera, belongs probably to this genus if not even to the Victorian 
species; because the fruit of Geijera, as far as hitherto ascertained, is not generically different from 
that of Xanthoxylon, and Jussieu's examination of the former plant did not extend over perfectly 
develojeed flow r ers. Moreover, some of the desert-shrubs, formerly thought to be restricted to the more 
eastern part of the Australian continent, have recently been brought from the vicinity of Sharks Bay, 
to which in all probability G. parviflora, along with Nitraria, Heterodendron, &c., will be found to 
extend, and from which locality, jerobably through Baudin's expedition, the plant was available to 
Jussieu and Candolle. 
Geijera pas*viflora, Lindl . in Mitch. Trop. Austr. 102; G. pendula, Lindl . I . c. 251. 
Leaves broad-linear, rarely oblong- or lanceolate-linear, veinless , tapering into a generally short petiole, 
on both pages of almost or quite equal color; panicle few-flowered; carpels rounded-blunt. 
On barren sandy or stony ridges or plains in the Murray desert. Thence advancing along the Darling 
and its tributaries to the waters of the Burdekin and also to the desert around Lake Torrens. 
A tall bush or small tree of strong* odor, in aspect resembling a Myoporum. Branchlets glabrous 
or when young scantily appressed-downy, almost terete, conspersed with more or less prominent glandular 
dots. Leaves blunt or acute, flat, 1-6 inches long*, 1—3 lines broad, not often broader, dotted with oil-glands, 
glabrous, one-nerved, not articulated with the leafstalk. Peduncles and pedicels slightly grey-downy, stout, 
angular; the latter generally shorter than the flowers and often upwards thickened. Bracts at the base of 
the pedicels solitary, deltoid, ciliolate, about J line long. Bracteoles roundish, coriaceous, appressed, seldom 
longer often shorter than \ line. Lobes of calyx roundish and very finely fringed. Petals spreading, glabrous, 
semilanceolate-ovate, yellbwish-white, truncate at the base, about 1 line long, with an inside faintly prominent
