ILLUSTRATIONS OF 



of the decurrent portion of the blade on the petiole. The flori- 

 ferous branchlets, often terminating in a spine, are | to 1 inch 

 long, and bear many small crowded leaves, and very numerous 

 flowers in almost aggregated clusters. The peduncles are slender, 

 somewhat thicker above, and 4 lines long : the calyx is tubular, 

 li hue long, with 5 acute, short, erect teeth, from which as many 

 costate ner\-ures descend to the base ; the teeth, more especially, 

 are covered with whitish pubescence. The corolla is cylindrical^ 

 slightly swollen below the mouth ; the tube is 6 lines long, 11 

 line diameter in the broader part, and quite smooth ; the lobes of 

 the border are erect, orbicular, very small, ith the length of the 

 tube, and are fimbriated on the margin with numerous ciliated 

 white hairs : the stamens are enclosed ; two of them nearly reach 

 the mouth of the tube, the other three being little more than 

 half their length ; all are pilose for a short portion of their length, 

 above the point of their insertion in the middle of the tube : the 

 style is slender below, much thickened above the middle, slightly 

 curved, and the length of the longer stamens : the stigma is 

 clavate and sub-bilobed : the ovary is narrow, oblong, smooth, 

 somewhat shorter than the calyx, and is invested at its base by 

 the very short induvial cup of the corolla : Schlechtendal states 

 that the berries are globose, red, and 3 lines in diameter.

 the southern portion of the province of Buenos Ayres.) The
