 Seeds very numerous, small, oval or oblong, mostly with a close smooth coat, often 

 apiculate at each end. — Herbs, or one peculiar species shrubby; with opposite 

 simple leaves, and axillary flowers on simple peduncles, wholly destitute of bractlets, 

 sometimes becoming racemose by the diminution of the upper leaves to bracts ; the 

 flowers various in color, commonly handsome, usually appearing in long succession.

A genus, as here maintained, of 40 or 50 species, far the greater number Pacific-North 

 American, a few extending to extra-tropical South America, one or two Asiatic, Australian, or 

 even South African. Several species, chiefly indigenous to California, are prized in ornamental 

 cultivation. 



In this and related genera, the lips of the stigma close with a quick movement upon receiving 

 pollen or being otherwise touched.

Guadalupe Island. Lower California, accords with this section except in having a shorter and 

 barely exserted tube to the corolla (which otherwise is nearly that of .V. Douglasii): so that this 

 section might as well be merged in Eunanus, to which Bentham referred it ; but the very long and 

 slender tube of the corolla in the two following species is very characteristic.

 contracted abruptly into a short petiole: calyx soon very gibbous at base on the 

 upper side : lower lip of the corolla very much shorter than the ample erect upper
