3. T. sarmentosa (sarmentose), I jam. lllnstr. j. 416: Benth. FI. Austr. 
iv. 390. A tall shrub with weak branches, or sometimes climbing to a great 
height, glabrous or sprinkled with short rigid hairs. Leaves petiolate, ovate, 
acuminate, entire, *2 to 4in. long, either glabrous or sprinkled with short hairs 
above, more or less pubescent or hirsute underneath. Flowers usually white, 
sometimes blue, sessile along the divaricate branches of terminal dichotomous 
cymes, without bracts. Calyx-segments lanceolate, shortly pubescent, under 
1 line long. Corolla-tube angular, varying from 1^ line to above 2^ lines in 
length ; lobes broad, obtuse or retuse, undulate-plicate, with a thick midrib, 
induplicate in the hud. Ovary tapering into a short style, which is very shortly 
lobed at the top, hut without the thickened ring of the other species. Fruit 
ovoid-globular, slightly compressed, the endocarp thick, of a loosely cellular 
texture although hard, with 4 very small real cells, and sometimes separating 
or separable into 2 2-celled pyrenes. — DC. Prod. ix. 516: T. orientalis, R. Br.

Hab.: Cape York, Darnel; Endeavour River, Banks and Solander, B. Brown; Port Denison. 
Fitzalan ; Edgecombe and Rockingham Bays. Dallachy ; Rockhampton, Thozet and several 
others ; Broadsound and Amity Creek, Bowman ; Port Mackay. Xernst. 
The species is also in the Mauritius. Timor, the Philippines, and probably in other islands of 
the Indian Archipelago. 
6. HELIOTROPIUM. Linn. 
(From the dowers having been supposed to turn to the sun ; 
English name, “ Turnsole.”) 
(Schleidenia. Etull.) 
Calyx deeply divided into 5 segments. Corolla with a cylindrical tube ; 
lobes 5, spreading, plicate and imbricate in the bud. Stamens inserted in the 
tube ; anthers often mucronate or acuminate and sometimes cohering by their 
tips, included or the tips slightly protruding. Ovary entire, 4-celled, with 
1 laterally attached or pendulous ovule in each cell ; style terminal, short or 
long, the stigma or stigmatic summit broadly umbrella-shaped or with a fleshy 
ring surrounding the base of a more or less distinct central cone or point. Fruit 
more or less 2 or 4-lobed or furrowed, separating into 4 1-seeded nuts, or in 
species not Australian into 2 hard 2-seeded carpels. Seeds with a scanty or 
rarely with a rather thick albumen.- — Herbs undershrubs or rarely shrubs, with 
appressed and strigose or with rigid and spreading hairs, very -rarely glabrous, 
b lowers usually small, sessile or pedicellate in one-sided simple or once or twice- 
forked spikes, with or without bracts, which when present are often not 
immediately under the pedicels. 
The genus is widely dispersed over the tropical and subtropical regions of the globe, a few 
species extending beyond the tropics both in the northern and the southern hemispheres All the 
Australian species except one belong to the genus or section of Heliotropium proper as limited by 
De Candolle, or to Heliotropium and Schleidenia as defined by Fresenius (in Mart. FI. Bras.) 
The section Heliophytum, with the fruit separating into 2 2-seeded carpels, established by De 
Candolle as a genus, comprises the H. indicum, Linn., a very common S. Asiatic weed. 
Skct. I. Platygyne. Stigma nearly sessile, umbrella-shaped, without any distinct 
central cone. 
Glabrous and glaucous prostrate perennial 1 . H cwrassavicum. 
Skct. II. Euheliotr opium. — Stigma a tldch ring at tin base of or round a central 
cone or point. Anthers obtuse or shortly acuminate, vat cohering (except in H. brachygyne?) 
Throat of the corolla not bearded. 
Flowers in scorpioid forked ok rarely simple spikes, without, bracts. 
Leaves oblong or lanceolate, petiolate or contracted at the base into a 
very short petiole. Style longer than the stigma .... 2 ”//. asperrimum.
