This genus has the appearance and the structure

REMARKS ON THE CLASS MONANDRIA. 



The genus GLOBBA, which has 2 stamina, is given 

 under the present class in the last edition of the 

 Hortits Keviensis, and in Persoon's Synopsis, i. 

 p. 3. Following Willdenow, we have given it in 

 Class II., though it certainly belongs to Class I. 

 Its generic character in the Hortits Ketvcnsis, is, 

 " Anthera duplex. Filani. lineare, incurvatum, 

 longissimum, appendiculatum. Stylus laxus, fili- 

 formis, in medk) antherae receptus. Sfigma in- 

 crassatum. Nectarium utrinque bifidum." 



I)r Smith has also given the genus CHARA under the 

 present class, with the following generic character : 



" Gal. 0. Cor. 0. Anth. sessilis. Styl. 0. Sent. 



plura ;" but we have, after Wildenow, given it 

 under MONOECIA Monandria. See English Bota- 

 ny, 334, and Fhi: lint. i. p. 4. 

 The genus ZOSTERA has likewise been given under the 

 present class ; but we have, after Willdenow, given 

 it under MONCECIA Monandria. 

 A new arrangement of the Scitamineje, or spicy 

 plants, has been proposed by the celebrated Mr Ros- 

 coe. This arrangement, which will be understood 

 from the following Synoptical Table, produces a se- 

 paration between the Scitaminete of true aromatic 

 plants, and the others which have neither their pecu- 

 liar construction nor their inherent qualities.

Persoon i& of opinion that the genera of this class, 

 from No. 1 to No. 1.5, including Globba, ought to 

 be referred to the Class GYNANDRIA. See Synopsis, 

 p. 1. 



On account of having a similar number of stamina, 

 the following species.belonging to other genera, might 

 :t:ll belong to this class. 



MONOGYMA. 



Mangifera Indica ; Tradescantia Monandra ; Va- 

 leriana rubra, angustifolia, calcitrapa. Alchemifla 

 aphanes (Aphanes arvensis of Persoon,) monandra ; 

 Polycnemum monandrum, and several species of Scir- 

 pvis and Cyperus. 



DlGYNIA. 



Lcersia monandra. Rotboella monandra. (Cavan- 

 illfs. ) Vniola lalifolia et gracilis. ( Michaux. )
