spreading leaflets. Florets of the ray five, neuter, with a very large 
suborbicular limb (IJ inch across) waved, somewhat plicate, pendu¬ 
lous, more than the lower half being stained on its anterior surface of 
a deep brown, the remainder, both in front and behind, being a bright 
yellow, except where the colour is stained behind by the brown in 
some degree appearing through it from the front; tube very short. 
Disk ovate; florets green, tube shining, barrel-shaped, limb short 
and revolute, segments ovate, much darker than the tube, waited ; 
stamens rising near the base of the tube; anthers dark brown, half- 
exserted; pollen yellow, granules orbicular; style below the cleft 
scarcely longer than the stamens, the segments linear, furrowed along 
the centre in the inside ; the stigmatic surface brown, waited, and near 
the apex bearded; achenia compressed, glabrous, colourless, bordered 
along the outer edge; pappus of tsvo short unequal teeth. Recep¬ 
tacle chaffy ; chaffs clavato-naviculate, embracing the achenia than 
which they are scarcely longer, cucullate herbaceous and villous at 
the top, flat membranous and wedge-shaped on the sides, each of 
which has a large oblong black mark in the middle. 
Popular and Geographical Notice. This genus is one of those 
which has been removed from the heterogeneous assemblage of plants, 
which were formerly included under the name of Rudbeckia, and the 
character by wtiich it may be distinguished seems perfectly good. 
The involucre seems to me to be certainly of one rowg and the suspi¬ 
cion expressed by De Candolle that what has been called the scales 
of an inner row, are probable the outer chaffs of the receptacle, is ob¬ 
viously correct. De Candolle reckons only four species, and expresses 
doubts about one of these. The present plant is altogether different 
from any of them, but perfectly agrees in generic relationship. They 
are all natives of North America, but the exact locality of this one 
I do not know. 
Introduction; Where grown; Culture. The plant figured 
was received from Mr. Rollison, and flowered in the greenhouse of the 
Royal Botanic Garden, Edinburgh, in August, 1840. There is every 
reason to believe it will bear cultivation without any particular care 
in the open ground. The flowers remain in perfection for weeks, and 
there is an abundant succession on the plants. 
Derivation of the Names. 
Obeliscaria pix>bably otsXiaKog and Kapa in allusion to the elevation of the 
disk of the flower. Dreaimondii from the late Mr. Drummond, to whom we 
owe its introduction into Britain.
