OF THE GENUS ILLIGERA. 293 
investigated the anatomy of the Сугосатрею in greater detail and adduced 
an additional character, the presence of rhaphides, as confirming the 
relationship with Lauracew. Almost simultaneously Pax (in Engl. u. 
Prantl, Pflanzenfam. IIT. ii. (1889) 126) added Bentham and Hooker 
Сугосагрею to Hernandiacese and placed the order near Lauracew, and 
this arrangement is probably a fair representation of our present knowledge 
of these genera. 
Illigera naturally falls into two distinct sections according to the character 
of the nectaries, six of the twelve species whose flowers are known having 
these organs eomparatively large and tubular, while in the remainder minute 
solid glands take their place. Blume’s two original species, upon which he 
founded the genus, happen to have belonged one to each section, and one of 
the characters upon which he relied to distinguish them, and which he used 
for the name of one of them (7. appendiculata), was this sectional character. 
I cannot, therefore, do better than apply the name Appendiculate to the six 
species having large nectaries, and Parviglandulate to the remainder.
