ON A NEW GENUS OF PLANTS OF THE 



NAT. ORD. CRUCIFER.^, 



From the Andes of Chili and Mendoza. 



In the year 1827, my valued friend and correspondent Mn 



Crucifi 



Hexapt 



but which having no fruity I could not then venture to pub- 

 hshj though its decidedly 6- winged germen seemed to separate 

 It from every other genus of its tribe. About the same time 

 Dr. Gillies sent me another plant, also without fruit, which I 

 considered, from the structure of its germen, to belong to the 



L 



same genus. That gentleman's return to Europe has put 

 nie in possession of perfectly fructified specimens of this 

 latter individual, and has enabled me to figure and describe it 

 as the type of a new genus of which he has been so fortunate 

 as to find a third species. In all the three, the fruit or ger- 

 men is furnished with six longitudinal broad wings, from 

 which circumstance I have derived the generic name. In 

 our species, indeed, there are not unfrequently from 1-4 in- 

 termediate lesser wings or crest-like appendages. The place 

 of the genus is amongst the Lepidinece, seu NotorhizcB angiis- 

 fisepta of De Cand., which that learned author thus charac- 

 terises: « Silicula septo angustlssimo, valvis carinatis aut 

 jakle concavis. Semina in loculis solitaria aut pauca, ovata, 

 immarginata. Cotyledones planse, incumbentes, septo paral- 

 lellas;'' and it may rank near to JEthionema, from which it 

 differs in its valves having three distinct wings, instead of one 

 tlorsal one, and in these valves being pendulous from the 

 s^'le, as in Cremolohus. 



With this latter genus I am unacquainted, save by the 

 %ures and descriptions of De Candolle; but that which 

 follows it, in the Systema anti 

 (nvillea, I find to have ir.
