upper corolla-lobes and arched over the corolla. Anthers reniform, 1 -celled by 
confluence of the cells. Style shortly bifid at the end. Nuts laterally attached 
to near or to above the middle, reticulate-rugose or rarely nearly smooth. — Herbs 
undershrubs or shrubs, showing considerable diversity in habit and inflorescence. 
Leaves entire, toothed or variously divided. 
The genus is widely distributed over the temperate regions of the globe, chiefly in the 
northern hemisphere, with a few tropical chiefly mountain species. 
Peduncles longer than the calyx, 1 or more flowered. 
Plant hoary or white, rigid. Leaves mostly entire. Peduncles rigid, 
all 1-flowered 1. T. racemosum. 
Plant green, nearly glabrous. Leaves mostly entire. Peduncles slender 
all 1-flowered or the lower ones 3 or 5 flowered 2. T. integrifolium. 
Plant green, pubescent or villous. Leaves toothed or cut or the upper 
ones entire. Peduncles slender, 3 or more flowered 3. T. coiymbosum. 
Flowers sessile or nearly so. 
Flowers in axillary cymes. Leaves mostly 3 to 6 or more lobed. Corolla 
with a tuft of white hairs on either side in the throat 4. T. ajugaceum. 
Flowers in terminal spikes. Leaves toothed or rarely lobed. Corolla 
with all 4 upper lobes small and distant 5. T. argutum. 
1. T. racemosum (racemose), Ii. Br. Prod. 504; BentJi. FI. Austr. v. 132. 
A perennial or undershrub with a woody rootstock and erect rigid more or less 
branched stems, from Gin. to above 1ft. high, hoary or white as well as the foliage 
and inflorescence, with a close minute tomentum scarcely wearing off from the 
upper surface of the older leaves. Stem-leaves linear-lanceolate or oblong-linear, 
obtuse, entire or very rarely 3-lobed, contracted into a short petiole, from under 
fyin. to above lin. long, the margins sometimes recurved and occasionally 
undulate-crisped ; the lower leaves in some specimens 3 together on each side of 
the stem ; the upper and floral ones ones gradually smaller, more sessile, broader 
at the base, the uppermost very small. Peduncles all 1-flowered, rigid, spreading, 
as long as or longer than the floral leaf, forming a stiff terminal more or less 
leafy raceme. Calyx 2 to 2| lines long, the teeth nearly equal, as long as or 
longer than the tube. Corolla-limb sparingly hirsute outside, the 4 upper lobes 
in lateral pairs, all nearly equal oblong and erect, the middle lower one twice 
as long. Nuts more or less pubescent, the adnate part of the inner face very 
hard. — Benth. in DC. Prod. xii. 576. 
Hab.: In the interior, Mitchell; Armadilla, IF. Barton; Curriwillinghie, Dalton ; Mt. Abun- 
dance and Iioulia, Bailey. ; Musgrave, T. Barclay -Millar. 
2. T. integrifolium (leaves entire,) F. Muell. Herb. Benth. FI. Austr. v 133. 
An erect perennial of Gin. to 1ft., with the habit of some forms of T. racemosum, 
with which F. v. M now unites it, but not so rigid and without any of the 
white tomentum so constant in that species, the calyx and young shoots very 
rarely slightly pubescent or hirsute and the corolla usually hirsute outside, the 
rest of the plant glabrous. Leaves lanceolate oblong or almost linear, the lower 
ones petiolate and -J- to lin. long, the upp'er floral ones smaller and more sessile, 
all entire. Peduncles much more slender than in T. racemosum, but mostly shorter 
than the leaves, the upper ones and sometimes all 1-flowered, the lower ones 
often 3- or 5-flowered as in 1 . corymbosum. Nuts pubescent. 
Hab.: In the interior, Mitchell; Bowen River, Bowman; Flinders River, Sutherland; Suttor 
River, Dorsay ; Armadilla, IF. Barton; Curriwillinghie, Dalton ; Glenormiston, Coghlan ; 
Dar River, Chas. IF. de Burgh-Birch. 
This species closely connects 1. racemosum and T. corymbosum, being as near to the one as to 
the other, and, as appears to me, cannot well be referred to either without uniting all three into 
on e.— Benth. 
3. T. corymbosum (corymbose,) R. Br. Prod. 504. Benth. v. 133, FI. Austr. 
Ail erect perennial, not usually much branched, from under 1ft. to 3ft. high, pube- 
scent with very short hairs passing sometimes into a hoary tomentum on
