Has. Zilverfontein, Drege/ (Herb. D., Hk., Sd.) 
A much branched, viscidly glandular annual, 4-12incheslong, diffuse (or prostrate ?) 
Leaves 1-14 inch long, their lobes or lobules not a line wide. Fl. heads small; 
the pedunc. 1-2 inches long. Rays seemingly a pale yellow. 
16. D. pinnata (Harv.); annual, glandularly pubescent and viscous, 
many stemmed, branched ; leaves pinnati-partite, the lobeslinear, obtuse, 
entire or here and there lobulate ; pedunc. short; inv. scales linear, acute, 
glandular; achenes of rays obconic, trigonous, the angles sharply 3-4- 
toothed, teeth rigid, deltoid; of the disc abortive. Calendula pinnata,

Namaqualand, A. Wyley! (Herb. Th., D., Hk., Sd.) 
A much branched annual, 6-12 inches high, glandularly pubescent and viscid in 
all parts. Leaves 4-1 inch long, the lobes 1 line wide or less, often quite entire, as 
often toothed or lobed. Pedune. 1-2 inches long. Achenes minutely glandular on 
the sides. Rays uncial, orange yellow. 
17. D. sinuata(DC.! 1. c. 72); annual, branched from the base, nearly 
glabrous, the branches leafy, ending in short peduncles; leaves oblong, 
obtuse, sinuate, narrowed at base, the younger ones subciliate ; inv. scales 
lanceolate-acuminate, quite glabrous, longer than disc; achenes of ray 
trigonous, everywhere tubercled ; of disc flat, with thickened rim ; rays 
orange. 
Has. Zilverfontein, Drege! (Herb. Hook.) 
A diffuse annual. Lower leaves 2-3 inches long, 5-6 lines wide. Rays about an 
inch long. 
18. D. calendulacea (Harv.); annual, branched from the base, glan- 
dularly scaberulous throughout, the young parts pubescent; branches 
leafy, ending in short peduncles; leaves oblong or linear-oblong, sinu- 
ate-toothed, narrowed at base, obtuse; inv. scales lanceolate-acuminate, 
black-dotted and albo-pilose, with membr. margins, longer than the 
disc ; achenes of ray (young) trigonous, tuberculated; of disc flat, with 
thickened rim; rays orange. 
Has. Namaqualand, A. Wyley! (Herb. D.) 
Nearly allied to D. sinuata, and perhaps a mere variety. It differs in its copious 
glandular pubescence and more evidently toothed leaves ; black-dotted invol. scales 
and longer rays. ‘Leaves 2-3 inches long, 4~5 lines wide, upper smaller. Rays 14 
inch long, orange yellow. The fl. heads resemble those of a “ marigold.” 
19. D. dentata (DC.); annual, erect, branched, glandularly pubes- 
cent; branches ending in naked peduncles; leaves oblong, narrowed 
at base, sinuate-toothed, puberulous, the upper narrower, sessile ; inv. 
scales lanceolate, acuminate, narrowly membrane-edged ; achenes un- 
known. <Acanthotheca? dentata, DC. 1. c. p. 74:
