Brittox : Cuban Plants New to Science 117 



Swamp near Atares Castle, Havana, June, 191 7 {Leon 7244). 

 Nearest B. frutescens (L.) DC, but easily distinguished by 

 its merely short-cuspidate outer phyllaries and pales. 



Spilanthes montana Britton & Blake, sp. nov. 



Shrub about 5 dm. high, sparsely dichotomously branched, 

 the stem stout, angulate, densely leafy, the branches erect, the 

 internodes mostly 4-10 mm. long. Leaves opposite, the blades 

 lanceolate, 2.5-4 cm. long, 4-8 mm. wide, narrowed to an obtuse 

 apex, cuneate at base, entire, coriaceous, slightly revolute, tripli- 

 nerved, glabrous, shining above, duller beneath ; petioles scarcely 

 margined, 2-5 mm. long; peduncles terminal and axillary, mono- 

 cephalous, glabrous, striate, 16-34 cm. long, sometimes bearing 

 two spatulate denticulate bracts 4 mm. long below the head ; 

 heads discoid, subglobose to ovoid-subglobose, rounded, 6-10 

 mm. high, 9-10 mm. thick ; involucre 3-seriate, slightly graduated, 

 5-6 mm. high, the phyllaries oblong or oval-oblong, rounded, 

 denticulate-erose above, sparsely glandular-ciliolate below, thick- 

 herbaceous with subscarious margin, papillose on back, obscurely 

 nerved ; disk-corollas white, 3.2 mm. long, sparsely papillose- 

 glandular below, with short obscure tube ; pales blunt, erose- 

 denticulate above, papillose-glandular on keel throughout and 

 sparsely hispid-pilose below; achenes (not quite mature) oblong- 

 obovate, 3 mm. long, ciliate ; awns 2, unequal, ciliate, 2-2.8 mm. 

 long. 



Top of Cajalbana, near the fall of the arroyo, Pinar del Rio, 

 Cuba, April 6, 191 5 (Leon & Charles 4936). 



Related to S. insipida Jacq. and 5. pauciceps (Griseb.) Blake, 

 but readily distinguished by its densely leafy stems and lanceo- 

 late entire leaves. 



Chaptalia comptonioides Britton & Wilson, sp. nov. 



Leaves several or numerous, deeply pinnatifid, spatulate- 

 oblanceolate in outline, 3-15 cm. long, short-petioled, obtuse or 

 acutish, membranous, the upper surface dark green, glabrous or 

 somewhat floccose, the under surface densely white-lanate, the 

 ovate terminal lobe larger than the semicircular lateral ones; 

 scape slender, floccose at least above, 2 dm. high or less ; invo- 

 lucre subhemispheric, 9-1 1 mm. high, its linear bracts acute or 

 acuminate, white-tomentulose with a green midvein ; achene fusi- 

 form, minutely hispidulous, brown, the angles white, the filiform 

 beak about as long as the body ; pappus longer than the beak, pale 

 brownish-white.
