This is very uiucl) like M. coccineum. Pax, with the type of which it has beeir 

 compared, but differs in the greenish colour of its inHorescence and much smaller 

 hract-cups and involucres. 



1 6. M. Ksessneri, N. E. Br. Stem annual from a tuberous root- 

 stock, 21 in. high in the specimen seen, herbaceous, glabrous. Leave* 

 thin when dried, apparently herbaceous, mostly about 2 in. apart,. 

 3-4J in. long, 1-2 in. broad, elliptic or the uppermost lanceolate,, 

 obtuse or subacute, apiculate, cuneately narrowed from the lower third 

 to a subsessile or subpetiolate base, entire, glabrous on both sides, green ; 

 midrib with a very distinct acute wing about 1 lin, broad beneath. Cymes- 

 axillary, nodding, \-\\ in. long, including the J- J in. -long recurving: 

 peduncle, with o-4 involucres. Bracts free, with overlapping margin ?;, 

 about J in. long and | in. broad, transversely elliptic, very obtusely 

 rounded at the apex and base, apiculate, wing-keeled down the back^ 

 glabrous, green ; veins inconspicuous except by transmitted light. 

 Involucre about J in. long, cup-like, open to half-way down in front and 

 sometimes on the dorsal side also, with the erect margin slightly thickened,, 

 entire, glabrous, scarcely or but slightly overtopping the subquadrate- 

 fringe-toothed glabrous inner lobes. Ovary exserted, reflexed, smooth,, 

 glabrous, scarcely acute and not crested at the angles, with a very small 

 cupular perianth at its base ; style trifid to the middle, with the branches

17. M. invenustum, y. E. Br. in Keio Bvlletin, 1 009, 329. Stems- 

 probably annual from a tuberous rootstock, 6-14 (or more?) in. high,- 

 terete, herbaceous or somewhat fleshy, glabrous. Leaves spreading^ 

 rather thick and rigid when dried, probably fleshy when alive ; petiole- 

 J-1 in. long.; blade i-lj in, long, ^-1 in. or rather more in breadth^ 

 orbicular-ovate or somewhat rhomboid-ovate, acute at the apex, cuneate 

 or rounded with a short cuneate extension into the petiole at the base, 

 crenulate and more or less crisped at the margin, apparently with a 

 somewhat papillate surface, glabrous to the eye, but with a few very 

 minute scattered hairs on both sides. Stipules 3-fid ; middle segment 

 scarcely 1 lin. long, linear, acute, ciliate ; lateral segments minute. 

 Cymes axillary at the terminal part of the stem, nodding, about i in., 

 long, including the 2 2i lin. -long recurved peduncles, composed of '^ 

 involucres. Bract-cup J in. long, oblique, open in front, with separated
