Rohr's plant was the pubescent form prevalent in Colombia, but appears 



to have represented an abnormal state in which the pedicels are short 



and arise from an abbreviated branch.

•Ad Stam. Martham (Bert,! in h. DC.)." An entire-leaved state. 



A widespread species of lowland Tropical America, growing mostly 

 on and near the seashore, but extending inland on river-banks, 

 plains and waste land. Very variable, but with most states found 

 in the same region or even in the same colony. Varies in size of 

 leaves, in form of leaves from linear-lanceolate to nearly ovate, and 

 in serration from entire to sharply serrate-dentate; varies in the 

 length of the pedicels; varies in length of and attenuation of the 

 sepals, in size of corolla from 8 to 10 mm. long, and somewhat pubes- 

 cent or glabrous within anteriorly, and in capsules from oblong to 

 ovoid, and from round and emarginate to acutish. Most con- 

 spicuously does the plant vary in pubescence, from glabrous through- 

 out, through states with the stem pubescent and the pedicels glabrous 

 or the pedicels sparsely pubescent — pubescent either with short or 

 long hairs — to forms densely hirsute on stems, pedicels, sepals and
