Haloragis Baeuerlenii. 



Very tall, glabrous ; leaves comparatively large, all opposite 

 and of equal form, somewhat decurrent into the short stalk, 

 lanceolar, crenate-serrulated, faintly veined, the apex of 

 the serratures deciduous, leaving a callous base, the upper 

 leaves not much smaller, and never alternate ; flowers, at 

 least in part, axillary and solitary ; two of the caJ.yx-lobes 

 deltoid, the two others dilated, or truncate-rhomboid ; tube of 

 the calyx, when fruit -bearing, expanded into four broadish, 

 conspicuously-veined membranes, of these, on each side 

 of the somewhat compressed tube two approximated ; styles 

 four, very short ; stigmas beardless ; truit rather large, 

 four-celled, pendant from a stalklet of half or nearly its 

 length ; pericarp spongy ; seeds irregularly developed. 



Between rocks in ravines on and near the summit of 

 Mount Tingiringi, at an elevation of about 5000 feet ; 

 W. Baeuerlen. This remarkable and seemingly quite local 

 plant attains a height of five feet, the stein linall}^ gaining 

 an inch in thickness. Branches spreading ; branchlets 

 opposite, quadrangular, as well as the young shoots often 

 of a reddish tinge. Leaves mostly from one to two inches 

 long and from one-third to half inch broad, flat, gradually 

 narrowed into the acute apex, dark-green above, somewhat 

 lighter colored beneath ; the leaves of young shoots pinnati- 

 lobed in their lower portion. Pedicles, so far as seen, 

 solitary in the axils, but perhaps also sometimes racemosely 

 arranged, as would appear from remnants of flowering 

 summits of branchlets. Stamens as yet unknown, only
