extend nearly over the petals; below the dark mark are
numerous small dark spots; lower petals yellow, tinged
with brown. Filaments 10, connected into a tube at the
base, 5 bearing anthers, two exceeding the others in length,
and one very short. Style red, about the length of the stamens.
Stigmas 5, purple, at length reflexed or revolute.
This is also a hybrid production, and was raised at the
sulphurea Nursery of Mr. Colvill, in 1823, from a seed of Dimacria color, that had been fertilized by the pollen of H. bi
and it is as near as possible intermediate between
the two; it thrives well in a mixture of turfy loam, peat,
and sand, and produces its numerous umbels of flowers all
the Summer; after flowering, and when the leaves are decayed,
it must be kept quite dry, until it shows an inclination
to grow again, which it will generally do some time in
December; it must then have the greater part of the dry
soil removed from its roots, and must be planted in a fresh
clean pot, which will require to be well drained; and as it
begins to grow it must be carefully watered. A collection
of those curious tuberous-rooted species, make a very pleasing
and splendid appearance, when grown together in a
group at the front of a greenhouse or conservatory, and, if
well managed, will continue to flower in succession, from
March to October; and although their flowers are not so
large as some of the shrubby sorts, yet their abundance and
brilliancy make up for that deficiency. One thing that has
been much against their general cultivation, is, that they
have been thought very diflicult to manage, but in our opinion
nothing can be more easy; the reason why people
have not succeeded with them, is, that they have rotted
them with water, after flowering, instead of keeping them
quite dry, till their root was ripened for growing again; the
greatest part of them are readily increased by the little
tubers of their roots.
