base, lower ones distant, patulous, oblong or cuneate -oblong-, to a 

 third subacutely bilobed, segments obtusate or rotundate, often 

 discoloured, upper ones approximate and more or less imbricated, 

 and near the flowers, and where tlie stem bifurcates more deeply 

 coloured, broader, cuneate, assurgent-concave, often to the middle 

 bilobed, very often 3- and sometimes 4-lobed, angular or obsoletely 

 denticulate, lobes alone obtuse, sometimes subacute, subequal, or 

 witli the exterior one, now the antical, now the postical, smaller ; 

 cells small to smallish, 4-6 sided, sul)leptodermous, chlorophyllose, 

 subopaque, lower ones slightly elongate, walls thick, angles not 

 thickened, or only very slightly, no trigones. Axilliar antical 

 leaf (at the fork of the stem) a little smaller than the others, 

 ovate, entire, rarely with a tooth added at the base. Stipules 

 small or minute, sometimes obsolete, rarely altogether wanting, 

 coloured, linear or subulate, entire or bifid, segments erect, narrow, 

 unequal. Sometimes between the normal stipules otlier abnormal 

 ones are found ec[ual in length to the leaves, falcate-lingulate or 

 irregular. Flowers ? terminal on stem, pistillidia 10-16. Bracts 

 2-3 pairs, laxly imbricate, concave, broader than long, 3-4-lobed, 

 lobes subacute, obtuse, or rotundate ; bracteoles rather smaller 

 than the bracts, oblique, ovate-lanceolate, entire, or deeply bilobed. 

 Perianth projecting much, bej^ond the bracts, green, p3^riform, some- 

 what compressed, very indistinctly trigonous, mouth shortly 6-iobed, 

 lobes 2-4 dentate, whole number of teeth about 18, shortly sub- 

 ulate, unequal; cells quadrate, opaque, pachydermous, composed 

 of one layer of cells, except at its base and a very little higher up, 

 where it is composed of two layers.
