Number 2355] (lecto [here designated]: BM 
001041064; isolecto: BM 001041065; CANB 
278978). 
Erect or spreading shrub, 0.8-2 m high. 
Upper stems and rachises without patent 
hispid hairs; short curved hairs retrorse or 
antrorse or no fixed direction, very dense, 
obscuring stem surface at *40 magnification; 
stalked glandular hairs absent. Cauline 
leaves 39-100 mm long, 11-36 mm wide, 
1.7-5.4 times longer than wide, base obtuse or 
broadly cuneate (> 60°) or narrowly cuneate 
(< 60°) or attenuate; marginal lobes crenate 
or serrate, irregular or regular, 12-20 on 
each side, acute or obtuse, 0.3-1.8 mm deep; 
petioles 9-19 mm long, 14-40% of lamina 
length. Lamina upper surface indumentum 
erect or curved, eglandular, 0.3-0.6 mm long, 
moderately dense (hairs 0.1-0.2 mm apart) or 
dense (hairs < 0.1 mm apart), sessile glands 
8-48 mm 2 ; lower surface indumentum lanate, 
tangled, 0.5-0.8 mm long, dense (hairs < 0.1 
mm apart) or very dense, obscuring surface 
at x40 magnification, sessile glands 16-64 
mm 2 ; transition from leaves to floral bracts 
abrupt. Floral bracts elliptical or ovate, 7-25 
mm long, 2-12 mm wide, not consistently 
exceeding verticils. Verticils (inflorescence 
clusters) overlapping near apex or all 
separated on rachis, cymes once dichasial at 
base then monochasial or twice dichasial (± 
globose), with 4-7 flowers per monochasium, 
peduncles 0-12 mm long on lowermost cluster; 
bracteoles spathulate, 4.8-7.5 mm long, 0.9- 
1.2 mm wide. Corolla tube longer than calyx, 
or same length as calyx; annulus 3.3-3.4 mm 
from base of corolla, annulus hairs 0.2-0.3 
mm long; upper lip ovate or elliptical, 4.2-4.8 
mm long, with glandular or eglandular hairs 
on outer surface; lower lip 5.1-6.1 mm long to 
end of lateral lobes, 9.7-11 mm long overall, 
with 20-100 eglandular hairs on platform. 
Longest stamens 10.5-12 mm long from base 
of corolla tube; filament hairs 0.9-1.1 mm 
long, mainly at distal end. Style 10.5-11.5 mm 
long; longer stigma lobe 0.75-0.9 mm long, 
shorter stigma lobe 0.4-0.5 mm long. Fruiting 
calyces 1.5-2 mm apart on rachilla; fruiting 
calyx cylindrical, 7.2-10.5 mm long, 3.3-4.8 
mm wide at lobe apices, 1.6-2.5 times longer 
than wide, exterior surface with all hairs same 
size and type, hairs eglandular, 0.5-0.7 mm 
long, sessile glands 16-80 mm 2 ; lobes acute, 
1.8-2.9 mm long. Fruiting calyx fringe hairs 
about the same length throughout, 0.5-1 mm 
long at apical end (or 0.15-0.3), 0.6-1 mm 
long at sinus end (or 0.15-0.3), sinus hairs 
absent, inner surface of tube with dense ring 
of long hairs in medial section or with sparse 
long hairs in medial section. Nutlets 2-2.4 
mm long. Figs. 5F, 10H.

Distribution and habitat : Anisomeles 
salviifolia is endemic to the Northern 
Territory. It is confined to the south-western 
Gulf of Carpentaria, including Maria Island, 
the islands of the Sir Edward Pellew group, 
and on the mainland at Bing Bong Station 
(Map 2). It grows in dune swales never far 
from the ocean, usually with grasses and 
woodland species, but sometimes on the edge 
of vine thicket. Soils are sandy and infertile.
