Hab. Yazo, in the Valley of Canta. 



In this plant, the leaves, and the flowers, too, are almost 

 wholly concealed by the long, white, and silky tufts of hairs 

 arising from their axillae. The P. lanata of Richard, from 

 Cayenne, approaches this in the length of its hairs, but the 

 leaves appear different.

Hab. Obrajillo, in the Valley of Canta. /3. Yazo, in the 

 same valley. 



In the var. /3. of this noble plant, the leaves, which are 

 often five or more inches long, become gradually smaller 

 upwards, so that the erect flowers, though axillary in these 

 smaller leaves, yet in reality form a large compact spiked 

 raceme. The flowers are more ventricose in the upper part 

 of the tube, than the figure in Cavanilles represents them 

 to be; and the segments of the limb are much longer: two 

 of them are recurved in front of the oblique mouth of the 

 corolla, and three behind.
