128 Mr. J. Miers on some of the Heliotropiege. 



(including a petiole of 3 lines), 14-2 lines broad, with very 

 sinuous and undulated margins. The many approximated 

 floriferous branchlets form a large corymbose head : each ter- 

 minal panicle has a peduncle 4 lines long, with four alternate 

 branches 3-4 lines apart, 4 lines long, each divided into two 

 spikes IJ inch long ; the sepals are 1 line long, oblong, obtuse^ 

 pilose outside ; the tube of the corolla is 1 J line long, with a 

 border 4 lines in diameter ; the pistil is 1 line long, the stigma 

 being a little longer than the style.

These specimens have a somewhat flexuous knotty stem, 

 1 foot long, above which they throw out several close ascending 

 branches, 4-10 inches long, with several divaricating branch- 

 lets, at distances of 6-9 lines, and about 4 inches long. The 

 leaves are 5 lines long, | line broad; the terminal peduncle, 

 6-9 lines long, bears three alternate short curving spikes, each 

 with about six flowers, all forming a corymbulose head ; the 

 sepals, 1| line long, \ line broad, are linear, pilose on both 

 sides ; the tube of the corolla is 2 lines long, a little swollen in 

 the mouth, pilose on its angles, with a border 4 lines in dia- 

 meter; the pistil is IJ line long, the stigma as long as the 

 style, cleft for nearly half its length into two obtuse segments, 

 which are minutely 2-denticulated at their apex. 



The original typical specimen is not to be found in the 

 Hookerian herbarium.
