Ind. iv. 690. An erect plant of 2 or 3ft., stems smooth or scaberulous. Leaves 
2 to 4in. long, and rarely fin. broad, linear or linear-lanceolate, obtuse, entire, or 
subserrate ; petiole none, or on some plants attaining ^in. Whorls of flowers 
axillary and terminal, to fin. diameter. Bracts setaceous, few and short. 
Calyx f to ^in., obovoid, the upper lip projecting, acute, 3-toothed, lower 2-fid, of 
a pale colour below, not striate above, sometimes spinescent. Corolla white. Nuts 
smooth, angular. — L. lavandulcefolia, Sm. in Rees Cyclop. Phlomis zeylanica,

Hab.: Indian plant. Some years ago I received specimens of what appeared to l e this plant 
from Mr. E. Cowley , Kamerunga, with the note that it was an introduced weed spreading 
in the Cairns district. I, however, have heard nothing of it since. 
The plant has a pleasant aromatic smell, and its flowers are used by the Brahmins to decorate 
their diety Iswara, according to Roxburg. 
18. PROSTANTHERA, R. Br. 
(From prostheke, a process, and antlieia, an anther.) 
(Chilodia and Cryphia, R. Br. Klanderia, F. v. M.) 
Calyx-tube usually straite, the limb 2-lipped, the lips entire or the lower one 
slightly emarginate. Corolla-tube short, dilated into a broad campanulate throat, 
the upper lip erect, usually short, slightly concave, broadly 2-lobed ; the lower 
lip spreading, 3-lobed, longer or in one section shorter than the upper lip, the 
middle lobe larger and usually emarginate or 2-lobed. Stamens 4, in pairs ; 
anthers 2-celled, the connective prominent at the back, sometimes cristate and 
usually produced into one or two linear appendages adnate at the base or in their 
whole length to the back of the cells, most frequently one of them rarely both free 
at the end or in a great part of their length, sometimes produced beyond the cell 
and tipped with a crest or tuft of short points or hairs, but sometimes both 
appendages very short or obsolete, the anther-cells themselves usually tipped by 
short points, not crested, and distinct from, although sometimes mistaken for, 
the ends of the connective appendages. Style shortly bifid at the end. Nuts 
reticulate-rugose, attached either obliquely at the base or adnate higher up. 
Seeds albuminous. — Shrubs or undershrubs studded with resinous glands and 
usually strongly scented. Leaves opposite. Flowers solitary in the axils of the 
stem-leaves, or opposite in terminal racemes, the floral leaves reduced more or 
less to deciduous bracts. Pedicels with a pair of bracts usually close under the 
calyx. 
The genus is limited to Australia, the greater number of the species are extratropical. 
Sect I. Euprostanthera. — Corolla-throat short and broad, upper lip short, very 
broad, erect, lower lip much longer with a large spreading middle lobe. Calyx-lips usually closed 
over the fruit. 
Series I. Racemoste. — Flowers in terminal racemes, the floral ones all or mostly reduced 
to membranous or broad acuminate or very deciduous bracts. 
Leaves mostly above lin. long, oblong-laoceolate, on rather long petioles, 
flat or nearly so. One anther-appendage much longer than the cell. 
Corolla pubescent. Bracts narrow 1. P. lasianthos. 
Leaves mostly Jin. long or smaller, on rather long petioles, flat or nearly 
so. Anther-appendages shorter than the cells. 
Leaves mostly about Jin. long, orbicular ovate or oblong. 
Leaves rather thick, mostly entire 2. P. ovalifolia. 
Leaves rather thin, mostly toothed. Lower calyx-lip longer and 
narrower than the upper one .' 3. P. incisa. 
Series 2. Convexs . — Leaves small or narrow, sessile or shortly petiolate, convex or with 
revolute margins when dry. Flowers axillary, the floral leaves similar to the stem-ones or rather 
smaller. 
Leaves linear, f to lin. long. 
Calyx glabrous inside or nearly so. Anther-appendage twice as long as 
the cell. Plant glabrous or nearly so 4. P. linearis.
