ones narrower and shorter. Involucres usually 3 on a common peduncle in the 
axil of each floral leaf and sometimes a second shorter peduncle in the same axil 
with a single involucre, the clusters of involucres numerous in terminal racemes 
leafy at the base, the upper floral leaves reduced to subulate bracts. Involucral 
bracts ovate, acute and aristate, the margins recurved, the upper or inner surface 
convex and hirsute, the larger one of each pair 3 to 4 lines long, with an external 
pair of subulate bracts. Corolla slender, shorter than the bracts, the lips as 
long as the tube. Stamens 2. Capsule clavate, ovate. Seeds 2, muricate. — 
Nees in DC. Prod. xi. 479 ; D. raceinifera, F. v. M. Fragm. vi. 69. 
Hab.: Cape York, Daemel. 
Also in Timor ; the typical specimens received from Decaisne, as well as others in the 
Banksian Herbarium, agree precisely with the Australian ones. — Benth. 
11. :: RUNGIA, Nees. 
(After Dr. Ferd. Runge.) 
Calyx small deeply 5-lobed ; segments linear-lanceolate. Corolla small bluish 
or white ; limb 2-lipped, upper lip emarginate shorter than the lower 3-lobed 
lip. Stamens 2 ; anthers 2-celled, cells parallel, subequal, or more often 
superposed; lower cell muticous or white-tailed. Ovary 4-ovulate. Style fili- 
form, minutely bifid. Capsule ovoid or oblong, shortly stalked ; after dehiscence 
the placentas with the retinacula rise elastically from the base of the capsule, 
scattering the seed. Seeds, 4 compressed, orbicular, glabrous, verrucose, some- 
times minutely, sometimes very strongly, so that the seed is concentrically rugose 
or subcristate. Diffuse or erect herbs or shrubs. Leaves entire. Spikes dense, 
terminal or axillary, one-sided. Bracts 2-ranked, or 4-ranked, with two of the 
ranks often flowerless ; flowering bracts often scarious-margined ; bracteoles 
similar to the bracts or narrow. 
The species belonging to Asia and tropical Africa. 
1. R. latior (diffuse), Nees in DC. Prod. xi. 472 ; Clarke in Hook. FI. Brit. 
Ind. iv. 516. Stems diffuse, herbaceous, hairy. Leaves ovate to broad 
lanceolate, cuneate at both ends, petiolate. Spikes oblong, dense, often clustered, 
about 1 in. long. Bracts roundly-obovate margins hairy, obscurely 4-seriate; 
bracteoles similar to the bracts, but smaller. Calyx nearly \\ line long, segments 
linear-lanceolate, hairy. Corolla 4 lines long. Anther-cells superposed, lower 
white tailed. Capsule 4 lines long, nearly glabrous. Seeds small, minutely 
glandular-verrucose ultimately glabrous. 
Hab : The above Indian species or one closely allied has become naturalised near Cairns. 
My specimens, which, however, were not perfect, were received from the late Mr. E. Cowley. 
12. JUSTICIA, Linn. 
(After J. Justice, a Scotch horticulturist). 
(Bostellularia and Khaphidospora, Nees.) 
Calyx divided to the base into 5 or 4 segments. Corolla 2-lipped, the upper 
lip erect, concave, entire or notched, the lower convex or with a longitudinal fold 
and veined in the centre, 3-lobed. Stamens 2 ; anther-cells oblique, one attached 
higher up than the other, the lower one usually mucronate or spurred. Ovules 
2 in each cell of the ovary. Style usually entire. Capsule contracted or com- 
pressed and seedless at the base. Seeds flat ; retinacula obtuse. — Herbs or 
shrubs. Flowers solitary or in clusters or cymes, axilliary or forming terminal 
spikes or panicles. Bracts various. 
A large genus, widely distributed over the tropical and subtropical regions of the globe. 
Flowers (small) in dense terminal bracteate spikes. 
Bracts linear or lanceolate, obtuse or acute, hispid or ciliate, bordered 
sometimes by a broad white margin
