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 Cycddites 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. — Proc. Linn. 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-genns. He has been good enough to enrich my work with the cha- racter of this, and an amendment of the genus Incarvillea.
