into the real Daucus Gingidium of Linnaus. 133 



montanus; and yet this erroneous citation is perpetuated in the 

 Vienna edition, in Reichard, and in Willdenow. How could 

 these able editors at the same time overlook the excellent figure 

 of Rivinus, Siaphjlinus folio latiore, Riv. Petit. In: t. 30, which 

 unquestionably belongs to our plant? 



I am not acquainted with the Daucus pohjgamus of Gouan, 

 Illusti: p. 9, to which the above synonyms of Boccone and Mag- 

 nol are, now applied, but I conceive it to be very different from 

 the Ginoidium. I do not presume absolutely to decide on this 

 question, but I beg leave to observe that Gouan seems not ac- 

 quainted with the true Gingidium by name, for he says the figure 

 in Boccone's Museum, t. 20, quoted under his Daucus hispanicus, 

 agrees better with Gingidium. Now that figure is not at all like 

 the true Gingidium, with which latter, however, Gouan's descrip- 

 tion of his D. hispanicus so well agrees, that I am persuaded the 

 plant he has described under this last name is truly the D. Gin- 

 gidium of Linnaeus. 



In his declining years Linnaeus cultivated in the Upsal garden 

 a Daucus, a specimen of which is preserved in his herbarium 

 without any trivial name. This is described in the Supplemcntum 

 under the name of lucidits, without any synonym, and said to 

 come from Mauritania. This specimen is evidently the Gingi- 

 dium of Matthiolus, with whose figures, in both editions, it 

 strikingly accords, and even still better with the Linnean defini- 

 tion of the involucrum, laciniis recurvis. This last excellent cha- 

 racter not being well expressed in those figures, convinces me of 

 Linnaeus having originally described the Gingidium from nature. 

 It is remarkable that neither he nor his son should have compared 

 this specimen with the definition or synonyms of D. Gingidium, 

 with which it so perfectly agrees; but they were perhaps misled 

 by a specimen in their herbarium marked Gingiaium, which is 

 really the Daucus (or more properly, as the French botanists 

 make it, Ammi) Visnaga.
