Similar to M. crenatum^ N. E. Br., in appearance, but the leaves are not wing- 

 keeled beneath, the peduncles are much shorter and the involucre is entire at the rim. 



216. Monadenium Chevalieri, N. E. Br. Stem annual from a 

 perennial rootstock, about 8J in. high and f lin. thick in the only 

 .specimen seen, herbaceous, glabrous. Leaves alternate, f to probably 

 about 2 in. long, but broken in the type, 1-2 lin. broad, linear, acute, 

 longitudinally folded, glabrous. Peduncles solitary, axillary, G-7 lin. 

 long, rather slender, with a pair of bracts and 1 involucre at the apex, 

 but possibly ultimately developing more, glabrous. Bracts free to their 

 base, 1 J-2 lin. long, 1 J lin. broad, elliptic, acute, with a slightly prominent 

 keel, glabrous. Involucre 1| lin. long, Ij lin. in diam., slightly con- 

 stricted under the entire rim and open to half-way down in front. 

 Pedicel abruptly recurved from the opening of the involucre, bearing 

 the remains of a distinct toothed calyx at its apex. Capsule fallen, not 

 seen.
