[ Plectranthus 
the floral leaves being all reduced to ovate reflexed bracts ; rarely the stock 
emits also long weak decumbent steins with a few distant pairs of narrow leaves. 
Flowers deep purple ( Dallaclnj ) or blue (F. v. M.), in false whorls of 6, forming 
long slender racemes. Pedicels 1 to 2 lines long. Calyx at first very small and 
open, when in fruit about 2 lines long, very much incurved, deeply 2-lipped, the 
upper lip formed of the broad obtuse slightly decurrent and recurved upper tooth 
with the 2 very small lateral lobes at its base, the lower lip as long as the upper, 
obtuse and emarginate, incurved and concave. Corolla-tube slender, nearly 2 
lines long, produced at the base into a long narrow conical spur ; upper lip ertet, 
broad, shortly 4-lobed, shorter than the tube ; lower lip oblong-obovate, very 
concave, rather shorter than the upper. Stamens shorter than the corolla, the 
two upper ones inserted much lower down than the lower ones. 
Hab.: Cape York, M'Gillivray ; Rockingham Bay, Dallaclnj ; and many other tropical 
localities. 
2. P. parviflorus (flowers small), Willd. ; Benth. in DC. Prod. xii. G7, not 
of Pi. Br. ; and FI. Austr. v. 78. An erect herb or undershrub very variable in 
size and indumentum, sometimes under 1ft. and much branched at the base, 
sometimes attaining 2 or 3ft. ; the stems rather fleshy, the whole plant pubescent 
villous or tomentose or rarely nearly glabrous. Leaves in the lower part of the 
stem petiolate, ovate to orbicular, coarsely erenate, rounded or cordate at the 
base, from under lin. to 2 or even 3in. diameter, usually rather thick soft rugose 
and tomentose or villous, but sometimes nearly glabrous and smooth. Flowers 
small, of a bluish-purple, in false whorls of about 10, forming long terminal 
leafless racemes either simple or slightly branched, the floral leaves reduced 
to minute bracts falling off from the very early buds. Pedicels usually longer 
than the very small flowering calyx; the fruiting calyx reflexed, much curved, 
striate, 2 to nearly 3 lines long, the upper tooth or lobe broad obtuse and slightly 
decurrent, the 4 lower ones incurved, very acute or subulate-acuminate, the 2 
lateral ones as long as, the 2 lowest longer than, the upper one. Corolla-tube 
about twice as long as the calyx, declinate and slightly gibbous at the base but 
not spurred ; upper lip short and erect, the 2 upper lobes rather larger than the 
lateral ones, the lower lip twice as long ; very concave. Stamens nearly as long 
as the lower lip. — P. cjraveolens, R. Br. Prod. COG ; P. australis, R. Br. Prod.

There are certainly two forms of this species in Queensland, distinguished by the size of plant 
and foliage. 
The species extends to New Caledonia and other islands of the South Pacific and to the 
Sandwich Islands. 
3. P. congestus (crowded), P. Br. Prod. 50G ; Benth. FI. Austr. v. 78. 
“ Kar-Kar,” Mitchell River, Palmer. A tall herb, attaining according to Dallaclnj 
10 to 12ft., usually hoary-tomentose. Leaves ovate, shortly acuminate or obtuse, 
coarsely erenate, narrowed into a petiole, soft and rugose, tomentose on both 
sides, about 2 or 3in. long, the lower ones longer. Flowers small, blue, 
numerous (often above 20), in dense false whorls, forming long almost 
spike-like interrupted racemes of which several are collected in a large 
terminal leafless panicle, the floral leaves reduced to minute very deciduous 
bracts. Pedicels very short. Calyx villous and copiously dotted and 
scarcely above 1 line long when in fruit, declinate or reflexed, the upper lobe 
broadly ovate, obtuse, not decurrent, the lateral ones acute but not much 
narrower, the two lowest narrower and rather longer, incurved and very acute. 
Corolla-tube about 2 lines long, abruptly declinate and slightly gibbous on the
