and short black stiff ones. CoROLLA nearly as large as in Cistus sal- 
vifolius, yellow, each petal broadly obcordate and marked near the 
se with a large purple spot. Stamens all fertile, very unequal in 
length. Stiema very large, globular, and nearly sessile. Ovary 
one-celled, containing many ovules attached to three parietal placen- 
tee which extend into the cavity of the ovary, so as nearly to divide it 
into three cells. 
Poputar anp GeocrapuicaL Notice. The beautiful group of 
Cistacez, is nearly confined to Europe and the neighbourhood of the 
Mediterranean, with a few North American species and one or two 
South American. The old genus Cistus, of Linneus, comprehended 
all the European and some of the American kinds, and was of itself 
so natural and distinct a one that it would have been hardly necessary 
to divide it at all; however, as the species increased, and as two differ- 
ent looking groups were observed, to which botanical characters were 
readily assigned, the small-flowered low-growing kinds were separated 
from the large gum Cistus under the name of Helianthemum, a genus 
now universally adopted. The-group was worked up with great care 
in the Prodromus of De Candolle, by a very accurate botanist who 
lived, as it were, in the midst of them; and by establishing subgenera 
or sections, all the purposes of scientific analysis were fully answered 
without interfering farther with the nomenclature. It is only to be 
regretted that the species were so much multiplied, and still more so in 
Sweet’s monograph, since published. But a much greater calamity 
has lately been inflicted on the genus by a modern French writer, who 
unable in this, as in other cases, further to extend the multiplication 
of species, has most unnecessarily multiplied the genera, and made so 
sweeping a junction of species as to reduce the 124 of the Prodromus 
to 27 only, a process which adds little to the scientific reputation of its 
author, and nothing but confusion to the synonymy of the group. 
INTRODUCTION; WHERE GRowN; CuLTuRE. Long since introdu- 
ced from Portugal; it is rather a tender species, requiring a warm 
rocky situation, well drained, and some slight protection in winter. 
With these precautions it will grow about four feet high, and become 
an object of great beauty. The figure was taken in July from a plant 
in the Birmingham Horticultural Society’s garden, where, as Mr. 
Cameron informs us, it bears full exposure in mild winters.
