Bailey and Gordon's Plants Reputed Poisonous and Injurious to Stock. 
1G. MOLUCCELLA, Linn. 
(A diminutive, from Molucca Islands, of which one of the species was 
supposed to he a native.) 
Calyx obliquely campanulate at the base, striate ; limb ample, dilated, 
reticulately veined, with 5 to 10 mucrones or spines. Corolla with an inclosed 
tube, which is obliquely annulate inside ; limb bilabiate; upper lip erect, entire 
or emarginately bifid ; lateral lobes of lower lip erectish, middle lobe spreading, 
broad, obcordate. Stamens 4, didynamous, ascending, lower ones the longest ; 
filaments naked at the base. Anthers laterally pedicellate at the tops of the 
filaments, 2 celled ; cells almost distinct, divaricate. Style about equally bifid at 
apex, stigmas nearly terminal. Nuts acutely triquetrous, truncate at apex. 
Annual glabrous herbs. Leaves petiolate, deeply crenate or cut ; floral similar to 
the stem ones. Whorls axillary, many-flowered. Bracts subulate spinose. 
Species two, belonging to the Mediterranean region. 
IVI . ieevis (smooth), Linn ; BentJi in D.C. Prod. 513, and FI. Austr. v. 73. 
Molucca Balm. A glabrous erect or ascending annual of 1 to 2ft. Leaves on long 
petioles, broadly ovate to almost orbicular. Flowers in distant false-wborls of 
6, the floral leaves generally smaller, but all on long petioles, the bracts connate 
at the base. Calyx very large, campanulate, oblique and membranous, the margin 
5-angled, with a small point at each angle, attaining sometimes nearly 2in. 
diameter. Corolla shorter than the calyx, whitish, the upper lip erect, concave, 
entire, the lower spreading, 3-lobed. Stamens 4, ascending in pairs under the 
upper lip. Anthers 2-celled. 
Hab.: Naturalized on the Darling Downs and other southern inland localities. 
17. LEUCAS, R. Br. 
(From the downy whiteness of the flowers.) 
Calyx erect, straight or curved and oblique at the top, 8- to 10-ribbed, 8- to 10- 
toothed. Corolla-tube not longer than the calyx, the upper lip erect, concave, 
entire or rarely notched, very villous outside ; lower lip spreading, 3-lobed. 
Stamens 4, ascending in pairs under the upper lip ; anthers 2-celled. Style 
with the upper stigmatic lobe much shorter than the lower. Nuts dry, smooth, 
triangular, obtuse. Herbs or undershrubs. Flowers in axillary false-whorls, 
white or rarely purplish. 
A considerable genus, spread over tropical and subtropical Asia and Africa. 
1. L. flaccida (weak), R. Br. Prod. 505. Benth. FI. Austr. v. 90. An annual 
with a hard branching decumbent base and ascending or erect flowering branches, 
often virgate or wiry and above a foot long, the whole plant pubescent or 
tomentose with soft appressed hairs. Leaves shortly petiolate, ovate, crenate, i 
to lin. long, the upper floral ones small. Flowers 6 to 20 or eveu more together 
in axillary false-whorls, the pedicels exceedingly short, the subtending floral leaves 
usually exceeding the flowers, the bracts within the false whorls very small. 
Calyx about 3 lines long when in flower and not much enlarged afterwards, 
straight, 10-ribbed, with 10 short softly subulate teeth, all equal or the alternate 
ones rather smaller. Corolla white (or blue according to Dallachy), not half as 
long again as the calyx. — Benth. in D.C. Prod. xii. 526. 
Hab.: Endeavour River, Banks and Solander ; Rockingham Bay, Dallachy; Rockhampton, 
Bowman, 0‘Slianesy ; Walsh River, B. C. Burton. 
Var.? petiolaris. Petioles longer than the calyx, as in L. decemdentata, but the fragmentary 
specimens appear to be in an abnormal state, and the calyxes are those of L. flaccida. — Cape 
York, HDGillivray. — Benth.
