upper side below the middle but not spurred ; upper lip about half as long as 
the tube, the 2 upper lobes broadly obovate, the 2 lateral ones very much smaller; 
the lower lobe or lip twice as long as the upper one and very concave. — Benth. in 
DC. Prod. xii. 66. 
Hab.: Endeavour Itiver, Banks and Solander ; Rockingham Bay, Dallaeliy ; and many other 
tropical localities. 
Leaves and branches crushed in water and drunk for internal complaints. — Palmer. 
4. P. foetidus (of a disagreeable odour), Benth. Lab. 35; DC. Piod. xii. 
65 ; F. v. M. Frar/m. ix. 161 and xi. 135. Plant of several feet high. Leaves 
8 to 6 or more inches long, 2 to 3 or sometimes more broad, cordate crenate- 
dentate ; rugose woolly-tomentose. Flowers dense, the spikes opposite, scarcely 
pedunculate. Calyx 2 to 3 lines long, the lobes as long as the tube. Corolla 
blue, the upper lip obcordate, bearded, lower lip cymbiform. Stamens free, 
glabrous ; anthers bluish, ovate-rotund. Style the length of the stamens, 
glabrous. Stigmatic lobes 2, very short. Nuts lenticular, curved, bright, 
minute. 
Hab.: Endeavour River, Banks and Solander ; Daintree River, E. Fitzalan. — (F. v. M.). 
5. COLEUS, Lour. 
(Referring to the stamens forming a sheath round the style.) 
Fruiting-calyx usually deelinate or reflexed, the upper tooth broad, scarcely 
decurrent, the lateral ones truncate or acute, the two lower usually longer, more 
connate and acute. Corolla-tube longer than the calyx, deelinate or bent 
down, not spurred ; upper lip short, 3- or 4-lobed, the lower much longer, entire, 
very concave or boat-shaped. Stamens 4, more or less connate in a tube round 
the style ; anther-cells confluent. Style shortly bifid at the top. Nut small, 
smooth. — Herbs rarely shrubs. Flowers in false-whorls of 6 or more, sometimes 
very dense, sometimes growingout into opposite variously branched cymes, forming 
terminal leafless racemes or panicles, the floral leaves reduced to small deciduous 
bracts. 
The genus extends over tropical Asia and Africa, the only Australian species being apparently 
the same as a common one in the Archipelago, although represented by endemic forms or 
varieties, which however require further investigation. The genus differs Erom Plectranthus 
chiefly in the monadelphous stamens. — Benth. 
1. C. scutellarioides (Scutellaria-like), Benth.; D.C. Prod. xii. 73; FI. 
Austra. v. 79. A tall herb or undershrub, the typical form pubescent or nearly 
glabrous, with slender branches. Leaves petiolate, ovate, acuminate or obtuse, 
slightly crenate-toothed and more or less purple underneath in the typical form, 
but varying much in the Australian varieties, mostly lj to 3in. long. Flowers 
rather small and numerous at first, in rather compact false-whorls forming long 
slender terminal racemes, but in most varieties as the flowering advances the two 
primary branches on each side lengthen considerably, converting the false-whorl 
into two opposite sessile once forked cymes, with the pedicel arranged along each 
branch. Calyx very small when in flower, enlarged afterwards, deflexed, the 
kibe striate, the broad upper lobe slightly decurrent, the lateral ones rather shorter 
and very obtuse, the 2 lowest much longer, connate to near the end where they 
form two small points. Corolla-tube slender, slightly gibbous at the base, then 
abruptly bent down, the throat dilated especially in the Australian varieties, of 
a pale bluish white as well as the upper lip, the lower boat-shaped lip or 
lobe of a deeper blue. Stamens not exceeding the lower lobe. — Ocimum 
scutellarioides, Linn. ; Bot. Mag. t. 1446 ; Plectranthus scutellariodes, R. Br. 
Prod. 506. 
Hab.: Harvey’s Creek, Russell River, Bailey ; Batavia River, H. Milman; Charters Towers, 
C. F. Plant. 
Distributed over the Indian Archipelago. 
The flowers are in the typical form rather smaller, and the fruiting cymes usually less 
developed than in Australia. — Benth.
