hairs, the floral leaves being linear, narrow, scarcely more 

 than 4 lines long. The flowers are axillary, the peduncle 

 being 8 lines long, lengthening in fruit to 18 lines : the calyx 

 as well as the peduncle is densely covered with short very 

 spreading rigid hairs, somewhat glutinous, it is 3 lines long, 

 tubular, 10-nerved, and divided half way down into 5 une- 

 qual, thickened, linear, obtuse, erect segments ; the corolla is 

 of a whitish, sometimes of a yellowish colour, slightly pubes- 

 cent outside, 5 lines long, quite infundibuliform, marked 

 with 15 longitudinal purplish veins, is enlarged in the mouth, 

 and has a very narrow border of 5 short spreading rounded 

 lobes : the filaments are dilated, fixed in the middle of the 

 tube: the ovarium is oblong and smooth: the style is erect, 

 smooth, as long as the corolla : the stigma is lunulate, or 

 deeply reniform, expanded and embracing the anthers within 

 its encircling rounded lobes : the carjsule is smooth, and of 

 the length of the incanescent persistent calyx.* 



This plant, it may be presumed, is widely disseminated, 

 for I can discover no difference between the specimens from 

 Texas, and those I found in the Pampas of Buenos Ayres, 

 either in their inflorescence, their leaves, or their habit, except 

 that from the latter place the pubescence is short, rigid, 

 widely spreading, and viscid at the tips, while from the 

 former, it is longer, soft, adpressed, and quite free from 

 glandular viscidity ; but this is not sufficient to constitute a 

 specific difference. 



The plant collected at Quillota in Chile and described and 

 figured by Colla, (Memorie di Torino, 38, 135, tab. 45), as 

 my Petunia viscosa,f is evidently the same species. 



* This species with sectional details is exhibited in Plate 20 of the " Il- 

 lustrations of South American Plants."

 nata.
