Caulis 0°6 em. diam., subito ad O'4 em. contractus. Folia 
15:0-20:0 em. long., 4:0-5:0 em. lat., membranacea ; petioli dum 
adsint 2:0 em. long., basi breviter vaginantes. Pedunculus fere 
30'0 em. alt., fistulosus ; bractea vix 4'0 em. long., glanduloso- 
denticulata, utrinque fulvo-pubescens; accedunt bracteæ per- 
paucæ juniores in involucri phylla transeuntes. Pedunculi 
proprii 0:3-0'8 em. long. Capitula 1:0 cm. long. et diam. In- 
volucri phylla extima 0:4 cem., interiora 0'8 cm. long., omnia 
apice fusca. Ligule oblonge, 3-denticulate, 4-nervosx, 0:6 em.

At first sight much like Z. subscaposa, X. Moore, but the larger 
leaves are sessile or at most shortly petiolate, the capitula are 
larger, with longer and broader involueral leaves, &e.
