the antheriferous portion, which is slender and subulate; the 
anthers are oblong, yellow, protruding beyond the mouth of 
the corolla. The fruit is unknown.* 
ACNISTUS. Schott. 
This genus was first proposed by Schott in 1829 (Wiener 
Zeitschrift 4.1180) upon a Brazilian plant considered to be 
identical with the Cestrum cauliflorum, Jacq. Hort. Schoen. 
3.41 tab. 325. Another species, also confounded with it, had 
been long previously known and figured by Plumier, under 
the name of Belladonna frutescens (tab. 46, f. 1). The authors 
of the Flora Peruviana have given a representation of a fourth 
species, under the name of Lycium aggregatum, (2.45. tab. 
182. f. a.); but as the characteristic features of the genus are 
not delineated in the figures above quoted, nor any exact 
details have, to my knowledge, yet been published, I offer the 
following from my own observations. 7 st
