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 sta¬ 
mens. Stigmas 5, purple, at length reflexed or revolute. 
This is also a hybrid production, and was raised at the 
Nursery of Mr. Colvill, in 1823, from a seed of Dimacria 
sulphurea that had been fertilized by the pollen of H. bi¬ 
color , 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 de¬ 
cayed, it must be kept quite dry, until it shows an inclina¬ 
tion 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 pleas¬ 
ing 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 difficult to manage, but in our opi¬ 
nion 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.
