FLORA OF MADAGASCAR. 327 
Stems densely tufted, about half a foot long, copiously branched, 
spreading, like theleaves densely pilose. Leaves sessile, alternate, 
2-1 in. long. Heads few to a stem, 1 in. diam. — Braets oblong, 
dull green, slightly pilose. Receptacle globose. Flowers, in- 
cluding the achene, „5 in. long. Achene glossy, obovoid, pale 
brown.—North-west Madagascar, Baron 5406! A plant very 
similar in habit, with densely white-cottony stems and obovate 
nearly entire leaves, gathered by Bojer at Bomatae Bay, and 
named by him Dichrocephala lanata, has a distinct paleaceous 
pappus, and should probably be considered a new genus. Our 
material, however, is too incomplete to characterize it properly. 
MiCROGLOSSA PSTADIOIDES, n. Sp. 
Fruticosa, sarmentosa, ramis apice solum tenuiter pubescentibus, foliis 
petiolatis oblongo-lanceolatis dentatis subglabris, capitulis parvis copiose 
corymboso-paniculatis, involucro campanulato bracteis pauciserlatis ad- 
pressis lanceolatis glabris, achenio subeylindrico glabro, pappo albido. 
A scandent shrub, with slender woody stems, glabrous except 
towards the tip. Petiole about an inch long ; leaves 4-5 in. long,
