undecayed after the lapse of an entire year. There are two - 
species belonging to the genus Cytinus mentioned by R. Brown, one 
from southern Africa and the other from equinoctial America. Cytinus 
Hypocistis is found on the roots of several species of shrubby Cistus in 
northern Africa, the Balearic Isles, Spain, South France, Italy, Dal- 
matia, Greece, and Turkey. It is said by Nyman (Syll. Fl. Hur.) to 
grow as far north as the Tyrol. Herbert mentions (Bot. Reg. xxxi. 85) 
having gathered it “‘on the rocky summit of Santa Decca, in Corfu.” 
The specimen of Cytinus Hypocistis, Linn., and Cistus salvifolius, Linn., 
(Sp. Plant. p. 738), on which it is represented growing, was gathered 
in the Western Bay in May, 1863.
