on the Hortus Malabaricus, Part IV. 213 
Jujuba, quotes the synonyma properly for the plant described by Rheede. I 
have already mentioned the strange error of this author in quoting the Mallam 
Toddali for the Rhamnus Napeca, which he calls R. Napea; but respecting 
this unfortunate plant, misled by his father’s Commentary on the Herbarium 
Amboinense (i. 121.), he falls into another gross error, quoting for it the 
Jujuba Indica spinosa, folio et fructu longiori of Plukenet (Phyt. t. 216. f. 6.) ; 
but no such plant is figured in that place, which represents the Prunus 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 Linnzean genus Rhamnus, 
and attempted to introduce our Indian plant as the /Mansana; but Jussieu, 
having restored the Zizyphus of Tournefort (Gen. Pl. 417.), has been followed 
by Willdenow, who calls our plant Zizyphus Jujuba (Sp. Pl. 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 (Znc. Méth. iii. 319.). "This excellent botanist 
considered the Jujuba Indica spinosa, folio et fructu 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.

farina alba tomentosa. Petiolus brevissimus, tomentosus, supra planius- 
culus. Stipule geminae, nunc marcescentes, tunc in aculeos indurascentes, 
quorum unus erectus, alter recurvus. 
Pedunculus communis axillaris, multiflorus, seepius bifidus, folio multo brevior.
