Triguera. 

 This Mtherto obscure genus was first described in 1786 by Cavanilles

these authors correctly class the genus among the Solanace^e. At a 

 much later period it was, however, referred by Don to the Nolanacece, 

 evidently from a misconception of its fruit ; but by Endlicher and other 

 botanists, it has since been placed at the end of SolanacecE, as a doubtful 

 senus of the order. Indeed nothing certain seems to have been known

for the kind and generous manner in which he opened to me the con- 

 tents of his rich herbarium, and for his Uberality in giving me a 

 specimen of Triguera ambrosaica, from which I have made the foUomng 

 analysis. Triguera, from the facts thus collected, will be seen to be 

 not only a truly Solanaceous genus, but one closely allied to Solamm : 

 in the structure of its stamens, and their arrangement upon the outside 

 of a free epipetalous annular ring surrounding the ovarium, it ap- 

 proaches the genus I described on a former occasion (lU. So. Am. PL 

 p. 33. tab. 8) under the name oi Piomndra (now the Cypliomandra of 

 Dr. Sendtner) ; but it differs from that genus in the form of its corolla, 

 in its seeds, and its distinct habit. In this respect it also resembles the 

 genus Ectozoma, which I have founded upon a plant from Peru, that 

 has its stamens fixed in like manner, upon a free epipetalous rmg. 

 Edozo^na, however, has a corolla with an imbricate aestivation, and 

 therefore belongs to the Atro:pacea, where it is placed in the tribe of
