ashington University 
The botanical expeditions to various parts of the West Indies, 
which have been conducted under the auspices of the New York 
Botanical Garden during the past twenty years, have materially 
advanced our knowledge of the flora of that region in securing 
additional material of many little-known plants and in discovering 
a considerable number of species new to science. Among re- 
cent collections of the genus Senecio from the American tropics, 
which have been submitted to the writer for identification, two 
from the West Indies appear not to have been previously de- 
scribed. Descriptions of these plants are now placed on record, 
as follows: 
Senecio subsquarrosus Greenman, sp. nov. 
Frutex .5-1 m. altus; ramis angulato-canaliculatis dense 
tomentosis; foliis alternis petiolatis elliptico-oblongis vel sub- 
obovatis 5-8 cm. longis 1.5-3 cm. latis obtusis integris vel re- 
mote sinuato-dentatis plus minusve revolutisque ad basim cu- 
neatis vel subrotundatis supra tomentulosis primo mox glabratis 
serius glaberrimis, subtus dense et persistenter tomentosis; 
petiolis .5-1 cm. longis tomentosis; inflorescentiis terminalibus 
sessilibus crebre corymboso-cymosis; capitulis circiter 8 mm. 
altis discoideis calyculatis; squamellis calyculatis spathulatis 
5-7 mm. longis subsquarrosis; involucri squamis 8 erectis lineari- 
lanceolatis obtusis 6 mm. longis extrinsecus dense tomentosis;
