Nov., 1912. CUBAN SENECIONEJE GREENMAN 325 



The general aspect of this species is similar to Senecio Brittonii 

 Greenm., but it differs in having an essentially sessile inflorescence, 

 fewer heads, shorter and densely white-pubescent involucral bracts, and 

 in the characters of the corolla. 



Senecio pachylepis Greenman, sp. nov. 



Frutex 1.5-2 m. altus; caule lignescente; ramis ramulisque teretibus 

 glabris vel juventate dense cano-tomentosis; foliis alternis petiolatis 

 oblongo-obovatis vel oblanceolatis 3.5-10 cm. longis 1.5-3.5 cm - latis 

 utrinque glabris ad apicem obtusis sinuato-dentatis ad basin integris 

 marginibus plus minusve revolutis; petiolis usque ad 1.5 cm. longis; 

 inflorescentiis terminalibus cymosis sessilibus; capitulis discoideis caly- 

 culatis; involucri squamis 8 lanceolatis vel lanceolato-oblongis 4-5 mm. 

 longis obtusis vel acutis glabris vel parce arachnoideo-tomentosis, 

 bracteolis calyculatis 5 spathulatis 2-3.5 mm - longis i mm. latis obtusis 

 crassiusculis ; floribus 10-12 flavibus; pappi setis fulvis; achaeniis 

 striatis hirtellis. Along rocky river trail, Rio Yamaniguey to Camp 

 Tao, Oriente, Cuba, 22-26 February, 1910, /. A. Shafer, no. 4008 

 (hb. Field Museum, cat. no. 294785, type, and hb. N. Y. Bot. Garden). 



In habit and foliar characters this species resembles S. eriocarphus 

 Greenm., but differs in having a close matted tomentum on the young 

 branches, glabrous leaves, smooth or slightly arachnoid involucral 

 bracts, and finally in having strongly spatulate and thickened calyc- 

 ulate bracteoles. The plant cited under the above number has been 

 referred to S. plumbeus Griseb.; but from that species, which it resembles 

 in habit and in foliar characters, it is readily distinguished by the 

 shorter petioles, blunter leaves, sessile crowded terminal inflorescence, 

 and the spatulate thick calyculate bracteoles. 



Senecio pachypodus Greenman, sp. nov. 



Frutex 1-2 m. altus; ramis ramulisque cortice verrucoso tectis gla- 

 bris ad apicem foliaceis; foliis alternis numerosis coriaceis lineari- 

 lanceolatis 5-8 cm. longis 2-4 mm. latis margine integris revolutisque 

 basi gradatim angustatis supra glabris subtus dense albo-lanatis; 

 inflorescentiis terminalibus paucicapitatis glabris; capitulis 8-10 mm. 

 altis calyculatis discoideis; squamellis calyculatis lineari-attenuatis ca. 

 6 mm. longis; involucri squamis 5 oblongo-lanceolatis ca. 7 mm. longis 

 brevi-acuminatis obtusis penicillatisque glabris, basi crassis ; floribus 5 ; 

 corollis 5-6 mm. longis; pappi setis albis; achaeniis columnaribus 2 mm. 

 longis cano-pubescentibus. - Collected at Camp La Gloria, south of 

 Sierra Moa, Province of Oriente, Cuba, 24-30 December, 1910, /. A.
