A hirsute herbaceous annual. Stems 6 to 18in. high. Leaves alternate or 
subopposite, petiolate, ovate subserrate, 1 to 4in. long, more or less woolly. 
Spikes 1 to 8in. long, mostly leaf-opposed, dense, ebraeteate. Sepals about 
1 line long, linear. Corolla-tube about 1 J line long, narrow-cylindrical ; lobes 
small, round, crenate. Stigma conoid-linear. Fruit 2 lines long, ovoid, ribbed, 
soon separating into 2 mitre-like pyrenes ; each pyrene with 2 cavities in addition 
to the seed-bearing cells. — Tiaritlium indicum, Lehm. Asperifol. 14 ; Wight.

15. *H. anchusaefolium (Anchusa-leaved), Poir. Buppl. 3 p. 28. Stems 
erect and branching, arising from a somewhat creeping underground one, often 
exceeding 1ft. high, whole plant covered with hoary strigose tomentum. Leaves 
alternate, about 2in. long, and 6 lines broad, linear-lanceolate, semiamplexicaule, 
subundulate. Peduncles terminal, solitary, bifid and trifid. Calyx-lobes linear. 
Corolla blue ; tube short. 
Hab.: Buenos Ayres and Brazil. Met with on the rocks about Brisbane as a stray from 
garden culture. 
7. TRICHODESMA, R. Br. 
(Referring to the anthers being bound together by hairs.) 
Calyx deeply divided into 5 segments. Corolla with a very short tube, almost 
rotate, with 5 acuminate lobes contorted in the bud. Stamens 5, inserted in the 
throat, the filaments very short and flat ; anthers erect, linear, ciliate, cohering 
by the hairs in a cylinder contracted into a long spirally-twisted beak formed 
of the terminal appendages of the anthers. Ovary entire, 4-celled, with 1 
pendulous ovule in each cell ; style terminal, filiform, with a minute stigma. 
Fruit of 4 1-seeded nuts, attached by their whole inner face, which when 
detached leave 4 cavities in the thick persistent prominently 4-angled axis. 
Seeds without albumen ; embryo straight, with a very short radicle. — Coarse 
hispid hoary or silky herbs. Leaves opposite or alternate, usually entire. 
Flowers in terminal one-sided simple or rarely forked racemes, usually accom- 
panied by bracts. 
The genus comprises very few species dispersed over the warmer regions of Asia and Africa. 
The only Australian species extends over nearly the whole range of the genus. 
1. T. zeylanicum (of Ceylon), II. Br. Prod. 496; Benth. FI. Austr. iv. 
404. A coarse hard annual, usually erect, not much branched, and often 
attaining several feet, the indumentum very various, sometimes close and hoary 
or longer and silky, more frequently consisting of short rigid appressed hairs 
or long loose scattered ones, or the various hairs intermixed, the longer ones 
usually arising from prominent tubercles. Leaves in the Australian specimens 
mostly alternate or the lower ones opposite, more rarely nearly all (as is usually 
the case in Indian specimens) opposite, linear, linear-lanceolate or rarely broadly 
oblong-lanceolate, obtuse, often 3 to 4in. long, the margins usually recurved. 
Flowers pale-blue, in simple racemes, with a leafy bract under each always shorter 
than the pedicel. Calyx-segments lanceolate, acuminate, J to ^in. long at the 
time of flowering, narrow or broad, valvate or reduplicate, often cohering at
