LX. UMBELLIFEJELE. 
Artinotus. 
into 8 lobes, or 2, 3 or more lobes. Umbels 4 to 6 lines diameter, containing 30 
or fewer nearly all fertile apetalous flowers. Calyx-lobes ciliate, about \ line long. 
Fruit about 1 line long, blackish, puberulous, margin white, ciliate. 
Hab.: Stanthorpe. 
This species Mueller considered to differ front .4. minor principally in being an annual. 
G. ERYNGIUM, Linn. 
(From a name of Dioscorides.) 
Calyx-lobes rigid, acute or pungent-pointed. Petals erect, with reduplicate or 
recurved margins and a long induplicate point, scarcely imbricate in the bud. 
Disk with a thick raised margin encircling the styles. Fruit obovoid or ovoid, 
scarcely compressed, the ribs inconspicuous, without vittfe. Carpophore deci- 
duous. — Herbs with prickly leaves and involucres. Flowers in compact spikes or 
heads, with a bract under each flower, the outer ones and sometimes some of the 
inner ones much longer than the dowers, rigid and pungent-pointed. Calyx- 
tube covered with transparent, acuminate or obtuse, flat or vesicular scales. 
The genus is spread over the greater part of the warm and temperate regions of the globe, the 
species most abundant and most varied in S. America Of the 4 Australian species, 1 is also in 
Chili, another extends to New Zealand, the remaining 2 appear to be endemic. — Benth. 
Some of the species of this genus have been suspected of poisoning stock. 
Leaves pinnately toothed, lobed, or divided, the radical ones narrow. 
Point of the petals jagged or ciliate. 
Flower heads ovoid or globular. 
Stems erect, or rarely shortly decumbent at the base 1. E. rostratum. 
Stems prostrate, resembling stolons but not rooting 2. E. vesicitlosum. 
Flower-heads oblong or cylindrical 3. E. plantagineum. 
Radical leaves obovate or oblong, toothed or lobed. Stem-leaves opposite, 
short, divaricately lobed. Stems dichotomous. Point of the petals 
obtuse, entire 4. E. expansum.

370. Stems erect, 1 to 2ft. high, the lower branches sometimes alternate, but 
more frequently the branches 2, 3, or 4 together, with a peduncle in the fork. 
Radicle leaves elongated, usually linear, pinnatifid, with entire or pinnatifid 
linear-pungent lobes, but sometimes the rhachis broader-linear, and the lobes 
reduced to teeth, or the rhachis very narrow with very few distant narrow lobes, 
or in wet places the leaves quite entire, grass-like, Gin. long, and marked with 
raised transverse lines so as to appear jointed. Stem-leaves only under the 
peduncles or branches, short, once or twice pinnatifid, and very rigid and 
pungent. Flower-heads ovoid-globose. Bracts very rigid and pungent, linear or 
linear-lanceolate, the outer ones and sometimes a few of the inner ones A to lin. 
long, the others smaller, and some not exceeding the flowers. Calyx-tube densely 
covered with linear obtuse scales or vesicles. Inflected point of the petals ciliate- 
denticulate or jagged. — DC. Prod. iv. 89 ; E. orinttm, A. Cunn. in Field,

Hab.: Common in inland localities. 
The species is found also in extratropicai South America. It is exceedingly variable in size> 
number of heads, and degree of division of the leaves. In some vigorous specimens the heads 
are Jin. or rather more in diameter, without the involucral bracts, which are 1 to l£in. long, and 
some of them with a few bristly lobes. In others the heads are few and small, and but few of 
the bracts attain 4in. In general, in arid situations the leaves are more divided with narrower 
more rigid lobes, and in wet situations either entire or simply pinnatifid. — Benth. 
Yar. subdecumbens. Radical leaves Gin. to lft. long, linear, entire, or with a few linear lobes. 
Stems short, sometimes decumbent, almost as in E. vesiculosum . — A form on the Darling Downs 
appears to belong to this variety.
