A NEW SENECIO FROM JAMAICA? 
J. M. GREENMAN 
Curator of the Herbarium of the Missouri Botanical Garden 
Associate Professor in the Henry Shaw School of Botany of 
Washington University 
In the spring of 1908 Dr. N. L. Britton and Dr. Arthur 
Hollick discovered in the Parish of St. Ann’s, Jamaica, a 
vine-like Senecio which appeared to them to be different 
from any species recorded in this genus. The plant was des- 
ignated temporarily by Dr. Britton as ‘5. НоШски, n. вр.” 
and generously submitted to the writer for examination. 
From the limited material available at the time the author 
was unable to find sufficient characters to separate it satis- 
faetorily from S. Swartz DC. Additional specimens have 
been secured since, and further information acquired as to 
the habit of the two plants concerned. The writer takes 
pleasure in confirming Dr. Britton’s view and in placing on 
record the following description: 
Senecio Hollickii Britton, sp. nov. 
Caulis lignescens scandens usque ad 6.5 m. longus cortice 
griseo tectis; ramis floriferis teretibus striatis brunneis gla- 
bris vel paree pubescentibus; foliis alternis petiolatis ovatis 
vel laneeolatis 2.5-12 em. longis 1.5—4 em. latis superne sen- 
sim angustatis acutis integris vel remote subdenticulatis 
utrinque glabris subtus pallidioribus basi acutis vel subeor- 
datis, margine plus minusve revolutis; petiolis ] em. vel 
minus longis glabris; inflorescentiis terminalibus cymosis
