SCORZON ERA UNDULATA. 
Native of Algeria and Marocco. 
Nat. Ord. Composirm.—Tribe CrncHonacesz. 
Genus Scorzonera, Linn. ; (Benth, § Hook. f. Gen. Pl. vol. ii. p. 531). 
Scorzonera undulata; caule erecto gracili elongato ramoso glabro, foliis 
glabris radicalibus pedalibus anguste elongato-lanceolatis attenuato- 
acuminatis vix undulatis, caulinis e basi lata sessile subulato-attenuatis, 
capitulis 2-24 poll. diam., involucri bracteis cano-tomentellis exte- 
rioribus late ovatis acutis apicibus recurvis, interioribus ter longioribus 
ovato-oblongis anguste marginatis, ligulis roseo-purpureis, corolle 
tubo gracili apicem versus barbellato, achenio obconico costato costis 
crenulatis, pappi setis inequalibus infra medium plumosis, 5—6 ceteris 
longioribus robustioribus supra medium scabridis. 
S. undulata, Vahl. Symb., vol. ii. p. 85; Desfont. Flor. Atlant., vol. ii. 
p- 219; DC. Prodr., vol. vii. p..117 (in part). 
That this is the true Scorzonera undulata of Vahl and of 
Desfontaine I have little doubt, though it differs somewhat 
from the description of the former in its flat leaves and more 
branched habit, and altogether from specimens in the Her- 
barium of the Greek plant with which Desfontaine and De 
Candolle confound the Barbary one. Vahl describes it as 
common throughout the region of Tunis, and Desfontaine 
has found it in sandy places. In many respects, and especially 
in habit, it approaches 8. purpurea, Linn., which has smaller 
bracts and very narrow leaves ; and also S. hispanica, which 
differs chiefly, if not only, in its yellow flowers. 
The specimen here figured was brought by Mr. Maw from 
Algeria, where he recognised it as apparently the same 
with a plant we found between Tangiers and Tetuan in 
Maroceo. It flowered in July, and had a very handsome 
appearance. 
Descr. Root thick, fusiform. Stem one to two feet, slender, 
_ branched, glabrous or with scanty white tomentum towards the 
ends of the branches. Radical leaves nearly a foot long, narrowly
