286 PROF. OLIVER ON NEW PLANTS FROM RORAIMA. 
Singular in the Witsenia-like habit of its stout stems; in our specimens 8—4 inches 
(ranging to 6-8 inches, Е. F. im Thurn) in length, lateral branches being given off 
immediately under the solitary scapes.

Folia 6-7 poll. longa. Seapus ... .. Bractese ovate v. interiores ovato-lanceolatz, 
38-11 poll. longæ. Sepala 12-12 poll. longa. Petala 2-21 poll. longa, inferne in tubum 
leviter curvatum coalita. Stamina petalis breviora; filamenta anguste linearia; anthere 
lineares. Ovarium cartilagineum, + poll. longum; stylus 1$ poll. longus. 
The leaves I have not seen, Mr. im Thurn having kindly supplied me with a note of 
their size and form. Не describes the foliage as “ Yucca-like." Our specimen consists 
of a well-developed capitulum and 8-9 inches of its scape. The flowers hardly admit of 
being satisfactorily analyzed. 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 interval 
above it. There is a figure of this remarkable plant in the Schomburgk collection of 
drawings at the British Museum.
