$. Othonna trifida: leaves trifid, linear; flowers lateral, 
peduncled. Stem ftirubby. Leaves fcattered, fomewhat 
fie(hy, with a white wool in the axils of the leaves. Seeds 
white, with wool. 
6. Othonna pe&inata, or wormwood-leaved African 
ragwort: leaves pinnatifid; fegments linear, parallel. 
This rifes with a (hrubby ftalk about the thicknefs of a 
mart's thumb, two or three feet high, dividing into many 
branches, covered with a hoary down. Leaves alfo hoary, 
about three inches long and one broad, cut into many 
narrow fegments almoft to the midrib. The flowers are 
produced on long axillary peduncles towards the ends of 
the branches; they have large yellow rays; and are fuc- 
ceeded by oblong purple feeds crowned with down. Lin¬ 
naeus remarks that the whole plant is often tomentofe. 
It flowers in May and June; and was cultivated in 1731 
by Mr. Miller, who fays, that the feeds were fent to Hol¬ 
land from the Cape, and plants raifed from them,in the 
Amfterdam-garden, in 1699. 
7. Othonna abrotanifolia,orfouthernwood-leaved Afri¬ 
can ragwort: leaves multifid, pinnate, linear ; the joints 
of the ftem villofe. This has a low ftirubby branching 
ftalk. The flowers are produced on ftiort peduncles at 
the ends of the branches; they are yellow, and the feeds 
are brown. It flowers from January to March. 
8. Othonna Athanafias : leaves pinnate, filiform; calyx 
hemifpherical, twelve-toothed. Stem ftirubby, like that 
of Athanafia, proliferous, even. Flower rather large, on 
a one-flowered peduncle ; corolla yellow, both in the ray 
and ciilk ; the former twice as long as the calyx. Seeds 
downy. 
9. Othonna ciliata : leaves pinnatifid, feflile; pinnas 
ovate, ciliate; peduncles terminating, elongated, one- 
flowered. 10. Othonna pinnata : leaves pinnatifid; pin¬ 
nas lanceolate, quite entire, decurrent. 11. Othonna 
trifurcata: leaves trifid-pinnatifid; pinnas linear; pedun¬ 
cles lateral, faftigiate. Found at the Cape by Thun berg. 
12. Othonna munita: leaves pinnatifid, imbricated, 
curved inwards; pinnas three-fided, awl-fliaped ; ftem di¬ 
chotomous; peduncles from the divarications. This re- 
fembles O. ericoides very much, and differs only in having 
pinnatifid leaves. 
13. Othonna coronopifolia, or buckthorn-leaved African 
ragwort: lower leaves lanceolate, quite entire; upper 
finuate-toothed. This rifes with a ftirubby ftalk four or 
five feet high, dividing into feveral branches. Leaves 
greyifli, placed without order; thofe on the lower part 
narrow and entire, but the others indented on the edges 
after the manner of hart’s-horn. The flowers are pro¬ 
duced in loofe umbels at the ends of the branches, and are 
yellow. Receptacle narrow, fomewhat convex, with hol¬ 
lows or cells in the middle ; the edges of the cells are fet 
with very ftiort briftly-ciliate hairs, giving the receptacle 
the appearance of being villofe; next the edge are fix or 
eight wider cells, receiving the germens of the female 
flowers. The feeds, which are the produce of thefe ger¬ 
mens, are largilh, obovate, fomewhat beaked at the bafe, 
ftriated, with a filky hoarinefs. Down very abundant, 
capillary, white-filky, three times as long as the feed. 
Cultivated in 1731 by Mr. Miller. It flowers from July 
to September. 
14. Othonna cheirifolia, or ftock-leaved African rag¬ 
wort: leaves lanceolate, three-nerved, quite entire, ftem 
fuffruticofe, creeping. This has a ftrong fibrous root, 
which ftioots deep in the ground, and fends out many 
woody items, which fpread on every fide, and trail upon 
the ground. The flowers are produced upon long thick 
fucculent peduncles, at the ends of the branches, and 
from the axils; they are yellow, the rays (harp-pointed, 
and not much longer than the calyx, which is cut into 
eight equal fegments at top; the di(k is large, and the 
florets as long as the calyx. The feeds are crowned with 
long down. It was difcovered by Dr. Shaw growing na¬ 
turally near Tunis in Africa. Mr. Miller cultivated it in 
1758 ; and it flowers from April to June.

15. Othonna craflifolia, or thick-leaved African rag¬ 
wort: leaves lanceolate, quite entire, fomewhat fleftiy; 
ftem upright. This has l'ound (talks, which at firft are 
herbaceous and fucculent, but by age become woody; 
they rife three or,four feet high, and divide into many 
branches from the bottom. Leaves thick and fucculent; 
about two inches long, and one broad in the middle; of 
a grey colour, placed without order, and feflile. The 
flowers are produced towards the end of the branches 
upon fucculent peduncles about four inches long, each 
fuftaining one yellow flower, fmaller than the preceding. 
It begins to flower in Auguft, and there is a fucceflion of 
flowers till the middle of winter. Cultivated by Mr. 
Miller in 1758. 
16. Othonna parviflora, or fmall-flowered African rag¬ 
wort : leaves lanceolate, glaucous, embracing; flowers 
panicled. Stem (hrubby, two feet high, even. Flowers 
fmall, yellow. 
17. Othonna tenuiflima, or fine-leaved African rag¬ 
wort : leaves filiform, fleftiy; ftem ftirubby. Stem from 
a foot to two feet high and more, even. It did not flower 
with Linnaeus, though he cultivated it for a long time ; 
but, from the villofe hairs at the bafe of the leaves, as in 
O. fruticofa, he placed it in this genus, till greater cer¬ 
tainty could be obtained. Mr. Miller had made it a 
Craflula ; and fays that it rifes with a ftirubby ftalk, four 
or five feet high, dividing into many branches, which at 
firft are taper and fucculent, but by age become woody. 
The leaves are very (lender, taper, fucculent, flaccid, ge¬ 
nerally turning downward, efpecially in winter, near 
three inches in length. It did not flower with him. It 
was fent him from Leyden by Adrian Van Royen. Ac¬ 
cording to the Kew Catalogue, it flowers in July. 
18. Othonna linifolia, or flax-leaved African ragwort: 
herbaceous; leaves linear, margined, grafly. Stem a 
fpan high, filiform, even; with one or two one-flowered 
branches; flowers only the fize of peafe, yellow. 
19. Othonna digitata, or digitate-leaved African rag¬ 
wort : leaves oblong, undivided, or digitate-toothed; 
peduncles one-flowered. Root bulbous. It greatly re- 
fembles O. ciliata, N° 9: 
20. Othonna lingua : leaves ovate-lanceolate, half em¬ 
bracing. Root bulbous. 
21. Othonna lateriflora, or fide-flowering African rag¬ 
wort: leaves lanceolate; flowers lateral; peduncles the 
length of the leaves. This is an upright (hrub, with the 
ftem the fize of a fwan’s quill. Flowers folitary, roundilh; 
corolla yellow. 
22. Othonna heterophylla: root-leaves ovate, angular¬ 
toothed ; ftem-leaves lanceolate, almoft entire. Root 
bulbous. 
23. Othonna ericoides, or heath-like African ragwort: 
ftem dichotomous, imbricated; leaflets acerofe; peduncle 
very long, folitary, from the divarications. This is an 
upright (hrub, refembling heath, commonly dichotomous. 
Flower (ingle, roundilh, not large. 
24. Othonna capillaris, or capillary-branched African 
ragwort: leaves lyrate 5 branches capillary. Root fibrous, 
very (lender. Root-leaves, and one or two ftem-leaves, 
lyrate, an inch long, even. Stems upright, a palm high, 
filiform, with the branches finally fetaceous and capilla- 
ceous, even. Flowers terminating, the fize of hemp-feed, 
yellow. 
25. Othonna Virginea: leaves wedged, gaftied. Stem 
(hrubby, compound, ereft, round. The young ftioots 
quite fimple: thofe of the prefent and former year leafy. 
Leaves fcattered in clufters, fmall in proportion to the 
plant, feflile. Flowers from the upper part of the in¬ 
ternodes, lateral, folitary, fmall, like thofe of Cotula; 
yellow. 
26. Othonna frutefeens, or ftirubby African ragwort: 
leaves oval, fomewhat: toothed; ftem frutefeent. This 
is allied to the next fpecies. Stem of the firft year a foot 
high, upright, fimple, round, even, fmooth. It differs 
from O. arborefeens in having remote toothed leaves, not 
cluftered.
