XCYI. LABIATE. 
[Prostanthera. 
concave, emarginate, the lobes of the lower lip much shorter, all fringed with 
rather long hairs. Stamens nearly as long the upper lip of the corolla ; anthers 
without any prominent appendages to the connective.

F. v. M. (Fragm. vi. 106) includes this in P. ovalifolia of which it has nearly the foliage, 
but the flowers are totally different. It is very near to P. nngens, but with d’fferently shaped 
leaves, and perhaps the corollas may not be quite the same. The two will require further com- 
parison on better specimens. — Bentli. 
14. P. microphylla (leaves small), A. Cunn. in Bentli. Lab. Gen.et. Sp. 454 
and in DC. Prod. xii. 562; Bentli. FI. Austr. v. 106. A low bushy or scrubby 
shrub rarely above 1ft. high, more or less scabrous-pubescent. Leaves very 
shortly petiolate, oblong or rarely oval-oblong, obtuse, thick, recurved from the 
base to the end, but without recurved or revolute margins, often all under 1 line 
long and very rarely exceeding 2 lines. Pedicels axillary, much shorter than the 
calyx and often not above ^ line long. Bracts small, close under the calyx. Calyx 
obscurely striate, pubescent or nearly glabrous, usually about 8 lines or rarely 4 
lines long, the lips much shorter than the tube, equal and obtuse. Corolla 
scarlet, slightly pubescent, fully twice as long as the calyx, the tube exserted and 
slightly incurved, enlarged upwards, the upper lip erect, concave, emarginate, the 
lower lip much shorter. Stamens exserted but shorter than the upper lip ; 
anthers with one appendage about as long as or shortly exceeding the cell, but 
very delicate and easily overlooked. — Benth. in DC. Prod. xii. 562 ; P. coccinca,

19. HEMIGENIA, R. Br. 
(From hemi , half, and genea, an offspring; in reference to only one of 
the cells of each anther being fertile.) 
Calyx 2-lipped or 5-toothed. Corolla with a dilated throat ; the upper lip 
erect, more or less concave, emarginate or 2-lobed, the lower lip longer, spreading, 
3-lobed, the middle lobe usually larger and often 2-lobed. Stamens 4, in pairs; 
anthers 1-celled, the connective elongated, produced beyond the insertion into an 
appendage or sterile branch, which in the upper pair is usually short dilated and 
bearded or crested at the end with short hairs, in the lower pair or rarely in both 
pairs glabrous and attenuate or bearing an imperfect cell at the end. Style 
shortly bifid at the end. Nuts reticulate-rugose, attached to the middle or higher 
up. Seeds albuminous.— Shrubs or undershrubs. Leaves opposite or in whorls 
of 3, entire, obtuse or rarely acute and never pungent pointed. Flowers all 
axillary, solitary or rarely in clusters, with a pair of bracts under the calyx. 
Corolla hairy inside at the insertion of the stamens, and usually at the base of 
the lower lip. 
The genus is limited to Australia. 
1. Biddulphiana (after Miss H. S. Biddulph), F. r. M. Viet. Xat. Sept. 
1890. A rather dwarf plant, almost glabrous except the flowers. Leaves faintly 
dotted, 14 to 2in. long, mostly lanceolate, flat or the margins slightly recurved, 
opposite or ternate, on very short petioles. Flowers axillary, solitary or in pairs, 
on very short pedicels, bearing at the base very short linear acute bracteolcs. 
Calyx 3 to 4 lines long, glandularly hairy, the lobes hardly half as long as the 
tube, almost equal, deltoid and somewhat acuminate. Corolla probably white, 
nearly twice as long as the calyx, the outside bearing minute spreading hairs, the 
2 upper lobes considerably shorter than the 3 lower ones, tube almost campanulate 
inside near the orifice, bearing crisp hairs. Anthers of the upper stamens 
1-celled, augmented by a large somewhat membranous blunt appendage ; anthers
