 ARUM bicolorum. Mart. Mill. DicJ. a. 10. 



This as well as feveral other fuppofed fpecies of Arum dif- 

 fers confiderably from the generic character, which therefore 

 needs correfting. The fpadix is furrounded at the bafe with 

 globofe rofe-coloured ovaries terminated with a hemifpherical 

 warty ftigma. There are no cirrhi as in Arum maculatutn t 

 but the anthers or rather maffes of pollen begin immediately 

 above the female flowers with hardly any intervening fpace, 

 and are at firft fomewhat diftinft, roundilh, then larger and 

 more irregular, and foon crowded together, covering the whole 

 fpadix to its extremity, Separating into irregular, four-fidea 

 mafles, much in the fame manner as ftarch does in drying, 

 but there is no appearance of the regular organifation ufual i « 

 anthers. This plant, which has been frequently miftaken for 

 the Akvm piclum of Linnaeus, was brought from Madeira, 

 where it is cultivated in the gardens for the fake of the beauty 

 of its leaves, which grow fometimes to a much greater fize than 

 the one reprefented in our figure. Said in the Hortus Kewenjts 

 to be introduced by McfiYs. Lee and Kennedy, Nurferyroen, 

 at Hammerfmith, in the year 1773, and flowered in the garden 

 of Mr. Fonnereau, at Eaft-Sheen, in 1778. 



Our drawing was made at Mr. Woodford's, Vauxhall, , 1 

 whofe ftove it flowered in January laft. Thrives beft when 

 placed near the window in the moft airy part of the ftove.
