Foliorum limbus usque ad 13 em. long., 3 em. lat. (exstant. vero folia. alia 
presertim juvenilia multo minora), trinervis, in sicco pagina superiore oliva- 
ceus, inferiore pallidior ; petioli 8—15 mm. long., seaberrimi. Corymbus unicus 
nobis obvius e capitulis tribus sistens, a basi ramosus; pedunculi proprii 2'5- 
4-5 em. leng. Involueri phylla longiora vix adusque 6 mm. long. ; intima 
4 mm. Receptaculi рае® 5 mm. long. .Ligule 12x55 mm., flave. 
Disci corolle 4 mm. long. Acheenia paullulum ultra 1 mm. long.; pappi 
paleze inter se inzequales, sordide albi, 0:5-2:5 mm. long. 
Can be easily distinguished from M. Brownei, Sch. Bip., by the long and 
narrow leaves, the shortly pointed pales of the receptacle, and the pappus.
