Nat. Ord. Composira#.—Tribe ANTHEMIDEZ. 
Genus Curysantuemum, L. ; (Benth. and Hook. f. Gen. Pl., vol. ii. incl.). 
Curysantuemum (Pyrethrum) Mawii; perenne, gracile, laxe tomentellum 
ramosum, ramis erectis teretibus subflexuosis apice nudis 1-cephalis, 
foliis sparsis ambitu ellipticis v. rhombeis triangulari-ovatis pinnatifidis, 
segmentis angustis incisis acutis, summis linearibus integerrimis, capi- 
tulis 1-14 poll. diam., involucri hemispherici squamis omnibus con- 
similibus lineari-oblongis acutis tenuiter marginatis viridibus ecarinatis, 
floribus radii ad 20 subbiseriatis, ligula late lineari-oblonga tridentata

superantem producto, acheniis teretiusculis glabris sulcatis costatis. 
A very singular half-shrubby species of the Pyrethrum 
section of Chrysanthemum, but referable to no known sub- 
section of that extensive group, though in certain respects 
allied to C. Myconis (Myconia Chrysanthemum) of the Mediter- 
ranean region, a yellow flowered species with achenes and 
pappus different in the ray- and disk-flowers. Amongst the 
Canarian forms where it might have been expected that the 
allies of the Maroccan should be found, there are none refer- 
able to the same sub-section as this, which may be called 
Scaphopappus, in allusion to the auriculate pappus, and be 
characterized by the costate achenes and auriculate very large 
Pappus, being similar in the ray- and disk-flowers, and by the 
white, or pink, or purplish ligules, and the brown disk 
flowers. Several other closely allied species to this inhabit 
the higher ranges of the Atlas at 6-10,000 feet elevation, none 
of which are described.
