frosted all over, and spotted streaked or varied more or less 
with dark purple, crowned chiefly on the inner side with a dimi- 
diate obliquely unilateral or inwardly secund 3-4-toothed crest 
or border formed by the production of the ventral wing, 2 prin- 
cipal side ribs, and dorsal keel. The inner ac-h. of the disk, 
except the three or four outer rows, are barren or abortive, and 
the teeth of their crown bright purple. — The extreme (P ta de 
S. Louren 9 o) state of this looks like a distinct sp., but passes 
by imperceptible gradations on sea-cliffs in the north into a, 
giving out in drying a strong Melilot or hay-like fragrance. 
Ismelia maderensis Don in Sweet’s Brit. FI. Gard. (ser. 2) 
iv. t. 342, with glaucous foliage and pale straw-coloured li« 
gules, erroneously stated to have been introduced by Mr. Webb 
from Mad., and referred both by DC. 1. c. and Schultz in WB. 
1. c. to the present pi., is evidently the Lanzarotan (Can.) Argy- 
ranthemum ochroleucum Webb. 
Ismelia Cass., founded on Chrysanthemum carinatum Schousb., 
and to which the name properly belongs, differs from Argy- 
ranthemum Webb in its herbaceous habit and flat or plano- 
convex receptacle. 
Ismelia Schultz in WB. is a compound of this pi. of Schous- 
boe with two Canarian Argyrantliema Webb. Ismelia Lesson 
and Ismelia Don differ no less widely from the original type. 
2. A. IliEMATOMMA (Lowe). 
L. twice as long as broad ovate or broadly ovate- oblong pinna- 
tisect, pinnae few (4-6) opposite subequal parallel remote dis- 
tinct spreading broad succulent and rigid, oblong, irregularly 
pinnatifld or deeply and strongly or coarsely inciso-toothed, 
the teeth ovate or triangular acute spreading • fl. solitary or 
2-3 together terminal ; ped. thickened and clavate upwards ; li- 
gules either more or less pink or rose-colour or w., disk atro- 
purpureous . — Chr. hcematomma Lowe in Hook. J. of Bot. viii. 
296. — Shr. per. SD. reg. 1, 2, rrr. Sea-cliffs and rocks of the 
Bugio or S. D. only, here and there quite up to the top of the 
island. May-July. — A shr. 2-4 ft. high, resembling A. pinna- 
tifidum (L. fil.) a, but with a less branched more straggling 
habit and very different foliage. Branches fewer stouter 
thicker and shorter, subdecumbent from the weight of the 
heavy fleshy foliage, or ascending, not fastigiate or corymbose, 
leafy only towards the ends. L. 2-3 in. long, 1-1 £ broad, in 
outline or circumscription broadly ovate or oval, in teeth and 
mode of division resembling somewhat those of Senecio incras- 
tatus Lowe or S. vulgaris L., cuneately attenuate at the base
