§ 4. Evantue. Inflorescence terminal ; flowers solitary or 2-4-nate, rarely 
clustered. Corolla mostly tubular, very rarely obconic or subcampanulate, at 
least 44 lin. long, usually longer. Anthers mostly included or more rarely sub- 
exserted or exserted, lateral, free, muticous or decurrent-denticulate or aristate, 
very rarely subcristate. Ovary sessile, glabrous or more rarely pubescent, 4-. or 
more rarely 8-celled, Leaves 3-4-nate, rarely 4-6-nate, Usually erect, stout, 
woody shrubs, from 1-5 ft. high; more rarely procumbent or slender. 
Mr. G. F. Scott-Elliot believes all the large-flowered Evanthes to be almost 
certainly ornithophilous (Ann. Bot. iv. 270). 
Exceptions: E. verticillata, var. B, has sometimes corollas less than 41 lin, 
long. Umbellate inflorescence may sometimes occur in E . verticillata. 
Many of the species of this section are very variable and difficult of definition. 
Some, with normally 4-nate leaves, occasionally have 3-nate leaves; more often 
the inflorescence varies according to the degree of luxuriance of growth, and the 
size of the corolla is frequently affected by the same cause. In using the key, 
therefore, it will often be found necessary to try under more headings than one.
