The leaves I have hot seen, Mr. im Thurn having kindly
supplied me with a note of their size and form. He
describes the foliage as " Yucca-like". Our specimen con-
sists of a well-developed capitulum and 8*9 ins of its scape.
The flowers hardly admit of being satisfactorily analysed.
They are very much larger than in other species seen by
me, and the tube of the united petals much wider. The
singular uncinate appendages are inserted with the style
upon the ovary, not as in some species at a distinct inter-
val above it.

to Lagenocarpus but differs entirely from that genus
and from the rest of the Cryptangieae in the lateral inflore-
