l-seeded, the fertile ce// being posterior, rarely anterior; less fre- 
quently 2-seeded. Seed with a minutely-pitted testa. 
ArriNITIES.— Nearest to Diapensiacee; the stamens being in- 
serted between the petals as in that Order, and the anther-lobes of 
Campylostachys abbreviata, diverging nearly in the same manner as in 
Pyaidanthera. As the stamens are interpetalous, these Orders should 
probably be associated with some monopetalous groupe which show 
a tendency to become polypetalous; and their structure differs but 
little from that of the Orders of the Erical alliance, resembling them 
especially in their bracts and calyx. Should the female flowers prove 
to be really apetalous, as they appear to be, Stiléacee may possibly be 
a connecting link between Zpacridee and Hmpetracee.

It is not my intention to discuss the medical properties of the plant - 
here represented : they will be found amply treated of in the July 
number (1850) of the ‘Pharmaceutical Journal, by Dr. Pareira. My 
attention was called to the plant by W. White Cooper, Esq., of 
Berkeley Square, as one that has proved, beyond all doubt, to be a 
Specific for tape-worm, and more speedy than any other known remedy. 
At St. Thomas’s Hospital it has been pretty extensively used, and the 
cases reported in the medical journals. 
As I fortunately possessed beautiful specimens of this plant in my 
herbarium, from the ‘ Unio Itineraria," gathered by Dr. Schimper, in 
Abyssinia, I have thought a representation of the plant could not be - 
unacceptable both to the botanist and to the medical practitioner. - 
Bruee's figure is nothing to boast of; and the plate in the Dict. des Sc. 
Nat. only gives the analysis of the flowers.
