A very pale, rigid, scrubby bush, glabrous in all parts, perhaps “viscid” also? 
Leaves 3-3 in. long, 1-2 L. wide. Drege’s “O tridens” partly (Hb. D., Hk.) belongs 
to our 7. leptoloba. 
26. T. pachypteris (Harv.) ; shrubby, robust, divaricately much 
branched, the old twigs and pedune. spinous, glabrous, viscid to the 
touch ; leaves linear-spathulate, with slightly recurved edges, thick, 
narrowed to the base, mucronulate, some entire, some 3-toothed or 
lobed; pedicels ending the twigs, short, glandular ; inv. sc. uniseriate, 
oblong, subacute, equalling the disc; rays 10-12, twice as long as the 
iny.; achenes rough-sided, amply 3-winged, the wings rigid, thickish, 
undulate, at length transversely lacerate. Osteosp. pachypteris, DC. l.

A robust, much branched, scrubby bush, “ the whole plant very glutinous to the 
touch and strongly scented, from 1-2 ft. high.” (M.E.B.) Leaves 4-3 in. long, 
1-2 1. wide. Heads ending short, lateral twigs, many-fl. Very near 7’. spinescens 
in foliage, but differing in habit and not glaucous. One of the folia of ‘‘O. spunescens 
in Hb. Th., marked No. 3, may belong to this; though slightly differing from our 
specimens. 
27. T. leptoloba (Harv.); shrubby, divaricately branched, the old 
twigs spinescent, glabrous, viscid ; leaves semiterete, midribbed below, 
thickish, glandular, either 3-lobed or pinnately 5~7-lobed, the lobes 
very blunt, exactly linear, as is the rachis; pedicels ending the twigs, 
glandular; inv. sc. subuniseriate, oblong, subacute, margined; rays 
6-8; achenes smooth-sided, with 3 rather narrow, membr. wings. Ost.

This is much more glutinous and glandular than 7’. spinescens, with exactly linear 
leaves and leaf-lobes, all very blunt, and smooth-sided fruit, which I have seen 
(perhaps not quite mature) in Hb. Hk. Some of Drege’s distributed specimens of 
** O. tridens, B. demissa” belong to this ; others to 7’. spinescens. 
Doubtful species. 
T. limonifolia (DC. 1. c. 458); “‘stem herbaceous, glabrous, branching; 
ascending-erect; radical and lower leaves oval, cuneate at base, tapering 
into a petiole, quite entire, 3-nerved; cauline sessile, often obtusely 
eared at base, linear-lanceolate, acute; heads corymbose, at length 
cernuous, gland-scabrid; inv. sc. linear-acuminate, narrow-edged; rays 
about 20, twice as long as the inv.; achenes 3-winged, quite smooth.
