GENERA. 

 Apodanthes. Pilostyles. 



Rafflesia and Brugmansia belong to the Indian Archipelago. Sapria inhabits the shady forests of 

 the extreme eastern Himalaya. Hydnora grows in Africa and South America. Cytinus principally 

 inhabits South Africa and tropical North America; one species (C*. Hypodstis) belongs to the Medi- 

 terranean region. Apodanthes and Pilo&tyles occur in America on the stems and branches of several 

 Leguminosee (Adesmia, Bauhinia, Calliandra). Some species are remarkable for their gigantic flowers ; 

 that of Rafflesia Arnoldi springs directly from the roots of Cisstis angustifolia, expands on the surface of 

 the earth, and attains nearly 3 feet in diameter. The perianth is 5-fid, spreading, and the throat bears 

 an annular crown ; its pink colour and scent of meat attract the flies, which thus become aids to its 

 fertilization. 



Cytinus contains, besides gallic acid and tannin, two colouring principles and a matter analogous 

 to ulmine. From the herbage and fruit is obtained an extract called Hypocistis juice; it is blackish, 

 acidulated, astringent and harsh in taste ; it was known to the ancients, and is still used in the south of 

 Europe for bloody flux and dysentery. The buds of R. Patma are used in Java for uterine haemorrhage. 

 Brugmansia also possesses powerful styptic properties. [The rhizome of Hydnora is used by the Hotten- 

 tots for tanning their fishing nets, &c.]
