on the Hoitus Malabaricus, Part IV. 213 



Jitjuba, quotes the synonyma properly for the plant described by Rheede. I 

 have already mentioned the strange error of this author in quoting the Mallam 

 Todduli for the Rhamnus Napeca, which he calls R. Napcea ; but respecting 

 this unfortunate plant, misled by his father's Commentary on the Herbarium 

 Amhoinense (ii. 121.), he falls into another gross error, quoting for it the 

 Jujuba Ind'tca spinosa, folio etfructu longiori of Plukenet (Phyt. t. 216. y. 6.) ; 

 but no such plant is figured in that place, which represents the Primus Zey- 

 lanica spinosa, longiori folio viridi , fructus ossiculo orbicularis scrobiculis referto, 

 while the Jujuba above mentioned is the cultivated variety of the Zizyphus 

 Jujuba. 



Gmelin, it would appear, was dissatisfied with the Linnsean genus Rhamnus, 

 and attempted to introduce our Indian plant as the Mansana ; but Jussieu, 

 having restored the Zizyphus of Tournefort (^Gen. PI. 417.), has been followed 

 by Willdenow, who calls our plant Zizyphus Jujuba (Sp. PI. i. 104.), without 

 making any material change in the synonyma or mentioning the cultivated 

 variety ; and, strange to say, places the genus in the Pentandria Monogynia, 

 although it has no stylus and two stigmata. Willdenow continues in the error 

 respecting the plants of Plukenet referred to the Zizyphus Napeca, which was 

 pointed out by M. Lamarck {Enc. Meth. iii. 319.). This excellent botanist 

 considered the Jujuba Indica spinosa, folio etfructu longiori of Plukene tas pro- 

 bably the same with his Zizyphus mauritiana ; in which case, I am persuaded 

 that this can only be admitted as a variety of the Perin Toddali, improved by 

 cultivation, such as the specimens which I have presented to the library at the 

 India House under the name of Zizyphus mauritiana. This variety grows in 

 the highest perfection near Patna, and is there called Bara Bayer.
