This is very much like I. coccineum, Pax, with the type of which it has been 
compared, but differs in the greenish colour of its inflorescence and much smaller 
bract-cups and involueres. 
16, M. Keessneri, V. 2. Br. Stem annual from a tuberous root- 
stock, 21 in. high in the specimen seen, herbaceous, glabrous. Leaves 
thin when dried, apparently herbaceous, mostly about 2 in. apart, 
3-43 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, 1-14 in. long, including the 4-4 in.-long recurving 
peduncle, with 3-4 involucres. Bracts free, with overlapping margin=, 
about 4 in. long and 3 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 4 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
