in the Isle of Wight agreed in having an elliptical outline, 

 unaccompanied with any inequality in the woody ellipsis^ 

 and also in having a bud in the axilla of each leaf; in these 

 respects differing from the Cycadites of the Isle of Portland, 

 and from all the recent species of Cycadece with which we 

 are acquainted, which have a circular outline and only 

 scattered buds.— ProcZmw. Soc, ii, p. 130 (May 6,1851). 



Incarvillea. 



Having, in examining the Himalayan species of Incar- 

 villea, observed some appearances not mentioned in, or at 

 variance with, the descriptions of that genus by Jussieu 

 and Lamarck, I was induced to ask the opinion of the 

 highest authority on the subject, and Mr. Brown has been 

 good enough to favour me with his opinion that the Hima- 

 layan species are too closely allied to be separated into a 

 genus distinct from the Chinese Incarvillea, but are yet 

 sufficiently distinguished to constitute a sub-genus. He 

 has been good enough to enrich my work with the cha- 

 racter of this, and an amendment of the genus Incarvillea.
