OF CYTINUS FROM MADAGASCAR. N 469 
fruit is baccate and the seeds minute and very numerous, às. in 
the other species of Cytinus. The embryo of the N 
small and nondifferentiated in the form of a roundish mass of 
cellular tissue. 
I propose to call the species Cytrnus BamomNr, after its dis- 
coverer. This makes a fifth species ofthe genus Cytinus, and until 
the present time no member of the Suborder Raflesiez has been 
recorded from Madagascar. The commonest species of Cytinus, 
C. Hypocistis, Linn., is confined to the Mediterranean region ; 
another species, C. dioicus, Juss., is found at the Cape of Good 
Hope ; and two members of the same genus have been described 
from Mexico. The only member of the nat. order Cytinacem 
that has been found in Madagascar is a species of Hydnora, 
which was seen by M. Grandidier *, but of which no specimens 
were brought home; the structure in this genus is very dis- 
similar to that found in Cytinus.
