[Echinosperm uw . 
1. EL concavum (back of nut concave), F. r. M. Fnujm. ii. 139 ; vi. 11G ; 
lien th. FI. Austr. iv. 407. An annual, strigose or hoary with appressed hairs, 
looser on the main stems ; stems either erect nearly simple and under 6in. high 
or longer, diffuse and almost woody at the base. Leaves linear or oblauceolate, 
the larger ones above lin. long, the upper ones passing into the small floral leaves 
or bracts. Flowers in one-sided leafy racemes, the pedicels at first very short, but 
lengthening to ^in. or more when in fruit. Calyx-segments about f line long, 
lanceolate, enlarging after flowering. Corolla about 1 line long, the tube with a 
ring of obtuse scales inside above the anthers, the lobes obovate-oblong, much 
shorter than the tube. Nuts about 2 lines long, very concave on the back, with 
thick raised almost involute margins bordered by stout conical glochidiate prickles, 
the enclosed area tuberc-ulate. 
Hab.: Southern localities to Cooper’s Creek. 
10. ERITRICHIUM. Schrad. 
(Plants woolly.) 
Calyx deeply divided into 5 segments. Corolla with a cylindrical tube, the 
throat with 5 minute gibbosities or scales or quite naked, the limb spreading, 
5-lobed. Stamens inserted in the tube, the anthers included. Ovary 4-lobed ; 
style filiform, inserted between the lobes, with a small usually capitate stigma. 
Nuts 4. rugose or reticulate, erect, attached to the shortly pyramidal or convex 
receptacle by an oblique aureole, the inner angle prominent. Seeds without 
albumen ; radicle short. — Herbs with the habit foliage and flowers nearly of 
Myomtis, but the inflorescence usually with bracts. 
There is a considerable number of species dispersed over the temperate and mountainous 
regions of Europe and Asia, and in America descending from the United States along the line 
of the Andes to Chile. The only Australian one is endemic. 
1. E. australasicum (Australian), A. DC. Prod. x. 134 ; Beuth. FI. Austr. 
iv. 406. Stems usually numerous, tufted diffuse or ascending, rarely nearly 
-imple and erect, mostly under Gin. long, the whole plant hispid, the hairs often 
yellowish on the young shoots. Leaves linear, obtuse, the lower ones sometimes 
almost opposite, rarely exeeding Hn., the upper ones smaller. .Flowers very 
small, nearly sessile in the axils of the bracts, forming simple one-sided leafy 
spikes. Calyx-segments very hispid, linear, scarcely 1 line long. Corolla 
scarcely exceeding the calyx, the lobes shorter than the tube. Anthers small. 
Style short. Nuts shorter than the calyx, rugose, with much-raised reticulations.

H:4>.: Southern localities. 
11. ROCHELIA, Reichenb. 
(After Anthony Rochel.) 
(Maccoya, F v. J/.) 
Calyx deeply divided into 5 or more segments. Corolla with a cylindrical 
sometimes incurved tube, the throat with or without scales inside ; limb spreading, 
5-lobed or rarely 4 or G-lobed. Stamens 5 or rarely fewer, included in the tube. 
Ovary 2-lobed, 2-celled, with 1 ovule in each cell ; style inserted between the- 
lobes, with a small usually capitate stigma. Nuts 2, erect, rugose, laterally 
attached to the narrow-conical receptacle. Seeds without albumen ; radicle- 
short. — Herbs with the habit of Myosotis, the inflorescence usually interspersed 
with bracts, the fruiting-calyx often more or less hardened at the base round 
the nuts. 
The genus comprises very few species from the Mediterranean region of the northern hemi- 
sphere and from western Asia. The only Australian species is endemic, but is very nearly 
allied to one of the east Mediterranean ones. The genus is nearly allied to Echivospeniunii, but 
has only 1 cell and ovule to each carpel — Beuth.
