turning black in drying. Leave- opposite. Flowers solitary in the upper axils, 
the upper ones often forming terminal spikes or heads. Braeteoles 2. linear,

The genus consists of a very few tropical Asiatic plants. The Queensland species has a wide 
range in the Archipelago and some parts of India. 
1. A. caeruleum (blue), /■'. Hr. Prod. 443; Hi nth. FI. Amtr. iv. 434. An 
erect, simple or branched, rather coarse annual, from under 1ft. to nearly 2ft. 
high, glandular-pubescent or villous all over, strongly scented. Leaves shortly 
petiolate ovate and scarcely exceeding lin. in the typical form, ovate-lanceolate 
and above 2in. long in some Asiatic specimens, the floral ones gradually smaller 
and passing into sessile bracts not exceeding the calyxes. Flowers blue, very shortly 
pedicellate, the lower ones axillary and distant, the upper ones forming a more 
or less compact terminal raceme. Braeteoles shorter than the calyx. Calyx 
very villous, oblique and slightly curved, 3 to 4 lines long, the upper segment 
lanceolate, the lower ones linear. Corolla 5 to G lines long, the lips nearly equal, 
shorter than the tube. Lower stamens nearly as long as the corolla, with 
1- eelled anthers ; upper ones shorter, the anthers with 2 cells separated by a 
broad thick connectivum. Capsule acuminate, rather hard, somewhat incurved, 
about as long as the calyx. — Pteroxtir/nia rilloxum, Benth. Scroph. Ind. . and in

8. STEMODIA, Linn. 
( Stemon , a stamen, and <//.<, double ; alluding to the anthers, which 
consist of two separate ones.) 
Calyx divided to the base into 5 segments or sepals, all equal or the upper ones 
scarcely larger. Corolla tubular at the base, the upper lip broad, entire or 
notched, the lower one spreading, 3-lobed. Stamens 4, in pairs : anthers 
2- celled with the cells quite separate, usually stipitate. Style dilated at the 
summit into 2 stigmatic lobes or rarely entire, not winged. Capsule globular, 
ovate or acuminate, opening septicidally in 2 usually 2-fid valves or in 4 valves, 
the placentas of the 2 carpels completely separating at maturity (at least in the 
Australian section). Seeds numerous, small, striate and usually reticulate.— 
Herbs, rarely undershrubs, more or less glandular-pubescent or villous and often 
strong-scented. Leaves opposite or in whorls of 3 or 4. Flowers solitary in the 
axils, the upper ones often forming terminal spikes. Braeteoles usually 2, 
linear, close under the calyx. 
The genus is chiefly from tropical and southern extratropical America, represented liy 2 
species in tropical Asia and Africa, one of which being the Queensland species. 
Leaves mostly lanceolate or oblong, sessile and stem-clasping or a few of the 
lowest, rarely petiolate. Stems erect or ascending. 
Flowers sessile or very shortly pedicellate. Corolla (about 3 lines long) 
shortly exceeding the calyx ... 1. .S', lythrifolia.

1. S. lythrifolia (leaves Lythrum-like), F. r. M. in Herb. Hook.', Benth FI. 
Ax<itr. iv. 4£G. A hard erect slightly- branched herb attaining 1 to 2ft., very, 
softly villous all over, almost woolly, and sometimes slightly viscid. Leaves 
ovate-lanceolate, oblong or lanceolate, serrate or almost entire, narrowed below 
the middle but usually dilated and stem-clasping at the base, soft and rugose, 
the larger ones 1 to 2in. long, the lowest sometimes more distinctly petiolate, 
the floral ones small and ovate passing into entire bracts. Flowers small, sessile 
in the upper axils, the uppermost forming a compact spike with the ovate bracts
