both sides, and ridged at the back, about twice the 
length of the calyx. Corolla of 5 petals, the 2 back 
ones reflexed, narrowly spatulate, obtuse, of a pale 
sulphur colour, with several red linear marks from the 
bend to the base; lower ones ligulate, connivent, con- 
cave, obtuse, of a pale sulphur colour. Filaments 10, 
united at the base, 5 only bearing anthers. Pollen yel- 
low. Germen and nrillus covered with soft villous 
down. Sti/le green, hairy at the base, and smooth on 
the upper part. Stigmas 5, red, and revoiute. 
This very natural division of Pelargonium, which 
differs so much from the others both in habit and cha- 
racter, we have thought requisite to form into a distinct 
genus. The essential character consists in the filaments 
being connected into a long tube, and never bearing 
above 5 perfect anthers; in the segments of the calyx 
being nearly equal, and the umbels of flowers always 
erect, not nodding before the flowers expand as in Pe- 
largonium; and moreover in its very difl^erent habit. 
This genus will comprise the greater part of the tuber- 
ous-rooted species of Pelargonium. We have named it 
in honour of Sir R. C. Hoare, whose collection of Gerani- 
acese exceeds every other in this country, and to whom 
we are obliged for many useful observations, which will 
be acknowledged in the course of our publication. 
The species of this genus require rather more than 
common care in their treatment in order to have them 
thrive well: being at one season of the year in a dormant 
state, they should be kept dry, till they begin to grow ; 
they may then be shifted into other pots and regularly 
supplied with water: the best soil for them is loam, 
peat, and sand, an equal portion of each mixed to- 
gether. The pots must be well drained with potsherds 
broken small, that the water may pass through freely: 
they are increased by the tubers of the roots taken off, 
and planted in pots, which must be placed on a gentle 
heat, or by seeds which are sometimes ripened. 
Our drawing was taken at the nursery of Mr. Wm. 
Malcolm, Kensington, in October last: we have no 
doubt of its being a real species, having seen a great 
many plants of it imported from the Cape of Good 
Hope, without the slightest variation in them.
