NEW COMPOSITE FKOM MONTE VIDEO. 

 By J. G. Baker, F.L.S. 



The following new species are contained in a parcel which I have 

 recently received from Signor Arechavelata, Professolf of Botany 

 in the University of Monte Video. Many other species belongmg 

 to tribes not yet monographed in the ' Flora Brasiliensis ' are 

 probably new ; but whilst it is yet undecided whether the work 

 shall be proceeded with I leave these for the present. 



Vernonia pterocaulon, Baker, n. sp. An erect, suffruticose, 

 unbranched perennial, about three feet in height ; the stem, under 

 side of the leaves, and especially the involucre and rachis of the 

 inflorescence, densely coated with persistent white cottony tomen- 

 tum. Stem bearing heads of flowers in its upper two-thu-ds, 

 winged throughout the leafy portion and lower 'pavt of the 

 inflorescence. Leaves sessile, erecto -patent, alternate, oblanceolate- 

 oblong, entire, cuneate at the base, subcoriaceous, bright green 

 and glabrous on the upper surface, those of the lower third of the 

 stem reaching a length of three to four inches, above this passmg 

 gradually into the bracts which subtend the lowest heads of 

 flowers, which are about an inch long. Liflorescence occupying 

 two-thirds of the length of the stem ; the lower heads solitary and 

 distant, subtended by reduced leaves ; the rest, except the upper- 

 most, w^hich are solitary, placed two or three together on a very 

 cottony, stout, flexuose rachis ; all sessile. Livolucre campanu- 

 late, one-sixth of an inch long and broad ; the lanceolate, multi- 

 serial, closely imbricated scales densely matted with white cottony 

 tomentum. Flowers about twenty in a head. Achene not seen 

 fully developed ; pappus one-sixth of an inch long, composed of 

 numerous whitish ciliated bristles. Corolla red, with short lobes, 

 and a' tube funnel-shaped in the upper and cylindrical in the lower 

 half. 



Corro Largo, in dry stony soil, Arechavaleta, 4103 ! 



Totally different, by its long unbranched rachis of inflorescence, 

 leafy at the very base only, from any species already known. In 

 leafage and general habit it recalls to mmd Fterocaulun spica- 

 tiun, DC.
