XCYI. LABIATE. 
1187 
Tribe V. Prostanthereee. — Stamens 4, in jrnirs ; anthers all with 2 perfect cells, or 1 
cell of all the anthers or also both cells of the lower pair sterile or abortive. Nuts prominently 
reticulate-rugose. Seeds albuminous. Calyx various. Corolla upper lip erect, usually short, 
throat broad. 
Calyx 2-lipped, ttie lips entire or nearly so. Anthers with 2 perfect cells, 
the connective not elongated IS. Prostaxthera. 
Calyx 2-lipped or 5-toothed. Anthers with an elongated connective bearing 
at the upper end one perfect cell. Connective with the lower end dilated 
linear or clavate or bearing an imperfect cell, usually bearded in the 
upper anthers. Leaves obtuse or rarely acute, not pungent 19. Hesiigenia. 
Calyx nearly equally 5-toothed. Lower anthers sterile and reduced to 2 
linear or clavate lobes. Upper anthers of one cell almost sessile on 
the filament. Corolla upper lip flat, 2-!obed 20. Wkstrixgia. 
Tribe VI. Ajugroideas. — Stamens 4, in pairs exserted from the very short truncate or 
deeply slit upper lip of the corolla (except very rarely in genera not Australian . ) Nuts promin- 
edtly reticulate-rugose, not succulent, usually attached to near the middle. Seeds without 
albumen. 
Corolla with the four upper lobes lateral, equal or the upper ones longer, the 
stamens exserted from between the 2 upper ones 21. Teucriuji. 
Corolla with the upper lip exceedingly short and truncate, the stamens 
exserted beyond it, the lateral lobes oblong, forming part of the lower lip 22, Ajuga. 
1. OCIMUM, Linn. 
(From oldmon, the old Greek name used by Theophrastus.) 
Fruiting-calyx enlarged and reflexed, the upper tooth orbicular or ovate with 
the margins decurrent, forming an upper lip, the 4 lower teeth small, pointed, 
equal or the two lowest with longer points. Corolla-tube straight, rarely exceed- 
ing the calyx, 4 upper lobes united in a broad shortly 4-lobed upper lip, the fifth 
lower lobe entire, flat or slightly concave, about as long as the upper lip. 
Stamens 4, declinate, the 2 upper ones usually with a tooth or tuft of hairs near 
the base ; anther-cells confluent. Style-lobes subulate or somewhat flattened. 
Nuts smooth or minutely-granular.- — Herbs undershrubs or rarely small shrubs. 
Foliage usually densely dotted and highly scented. Flowers in false-whorls of G, 
rarely 10, arranged in terminal racemes, the floral leaves reduced to small 
deciduous bracts. 
The genus extends over the tropical and subtropical regions of the New as well as the Old 
World, two or three species having been very long in cultivation amongst aromatic herbs. 
The only Australian species is a slight, almost endemic variety of one of the common Asiatic 
ones. 
1. O. sanctum (sacred), Linn.: Bentli. in DC. Prod. xii. 38, var. 
angustifolium ; and FI. Aitstr. v. 74. “ Mooda,” Cloncurry, “ Bullabulla,” Mitchell 
River, Palmer. “ Kobilo,” Western Queensland, F. O. Foster. A branching 
perennial or undershrub, usually forming a thick woody base, but sometimes 
flowering the first year so as to appear annual, rarely exceeding 1ft. in height, 
more or less hirsute with spreading or reflexed hairs. Leaves on rather long 
petioles, mostly oblong-lanceolate, L to lAin. long, bordered by a few coarse teeth 
or nearly entire, more rarely ovate. Flowers small, purple (F. v. M.) or pure 
white (Bowman), in loose whorls of G, forming terminal racemes, the bract-like 
floral leaves very small. Pedicels slender, often as long as the calyx. Calyx 
scarcely 1 line long at the time of flowering, when in fruit 2 to 2i- lines long, 
the upper lobe orbicular, the lateral ones small and acute, the 2 lowest with long 
subulate points, Corolla-tube nearly as long as the calyx, the lips as long as 
the tube, the lower lobe or lip broadly ovate, or nearly orbicular. Stamens 
shortly exserted, the 2 upper ones with tufts of hairs near the base of the 
filaments. Style-lobes slightly flattened. — 0. anisodornm and 0. caryopliyllinum ,
