286 PROF. OLIVER ON NEW PLANTS FROM RORAIMA. 



Singular in the JPitsenia-like habit of its stout stems ; in our specimens 3-4 inches 

 (ranging to 6-8 inches, E. F. im Thurn) in length, lateral branches being given off 

 immediately under the solitary scapes. 



312. Abolboda Sceptrum, Oliv., sp. nov. ; foliis lineari-lanceolatis acutis rigidis lsete 

 viridibus leviter glaucescentibus, scapo crassitie penna3 anserinte, floribus capitatis, 

 capitulis floriferis 4-5 poll, diam., bracteis ovatis acutis rigidis sepalis ^-f breviori- 

 bus, sepalis ovato-lanceolatis subaBquilongis lateralibus carinatis, petalis limbo ovato 

 flabellatim venoso, ovario ovoideo, stylo longo basi appendicibus 3 crassiusculis arete 

 uncinatis ovario sequilongis circumdato, ovula plurima.

Eolia 6-7 poll, longa. Scapus Bractese ovatse v. interior es ovato-lanceolatae, 



f-1^ poll, longa?. Sepala 1^-lf poll, longa. Petala 2-2J poll, longa, inferne in tubum 

 leviter curvatum coalita. Stamina petalis breviora ; filamenta anguste linearia ; antherse 

 lineares. Ovarium cartilagineum, \ poll, longum ; stylus If poll, longus. 



The leaves I have not 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 consists 

 of a well-developed capituluni 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.
