shorter petioled, and more closely clustered than in the example shown by the 

 photograph. 



2. Mature plant. The mature plant (fig. 3), about 1.5 m. high, has normally a 

 strong central stem from the base of which grow long side branches, about 1 m. 

 long, and shorter branches are usually present about midway up the central stem. 

 Flowering portions of the stem are usually unbranchod. Red papillae at the base 

 of long hairs give the upper green portions of the stem a very characteristic color- 

 ation. The foliage on upper portions of the plant (fig. 4) consists of ovate-lanceo- 

 late leaves, short petioled or almost sessile, and crinkled.
