the cortusoides of Siberia, especially in regard to foliage 
and pubescence,. as well as habit of growth; but the indefi- 
nitely numerous segments, inflated distention of the calyx, 
progressive with the growth of the fruit within it, and 
toothed margin of the divisions of the corolla, still render 
it a striking anomaly among its congeners. 
The plant not having been yet known in its wild state, 
can we be sure that the multiplication of the segments of 
the calyx does not arise from luxuriance, induced by exotic 
cultivation? In regard to the number of the teethlike 
valves by which the capsule opens at the summit, it is true 
to the generic type. 
We should have continued the name of sinensis, by 
which the species was mentioned to us by Mr. Sabine; but 
we find a Primuta of that title in the Flora Cochinchinensis 
of Loureiro; an author, it is true, who cannot be deemed 
any great authority in regard to this genus, having regis- 
tered the now well-known Hypranera hortensis under that — 
head, by the specific denomination of mutabilis. But still it 
is possible his Primua sinensis may be of the present genus ; 
and at all events our plant has not been published by that 
name. 
The Monograph of this genus by M. Lehmann, contains 
42 species, exclusive of the present and another from Terra 
del Fuego, recorded in the Banksian Manuscripts as Prt- 
-MULA. antarctica.
