filaments dilated below, and two ovules in each cell ; Luvunga, con- 

 sisting of unarmed or thorny shrubs, with cupuliform calyx, and 

 stamens often monadelphous at the base, with anthers always linear. 

 The leaves are trifoliolate and punctuate, and the inflorescence 

 • axillary. 



In Atalantia and JParamygnia, composed of unarmed or thorny 

 shrubs, the leaves are constantly unifoliolate. The flowers, axillary, 

 constructed on the same plan as the preceding genera, have in the 

 former a calyx 3-5-lobed, or unequally cloven, from six to ten 

 stamens, free or connate, with oval or cordate anthers, a cupuliform 

 disk, and uni- or biovulate cells. In Paramenia, the calyx is entire 

 or lobed, the stamens, eight to ten in number, have oblong-linear 

 anthers, and the disk-bearing receptacle takes the form of an elevated 

 thick column. 



Feronia belongs to a distinct subseries, which might be named 

 Citrete, because the genus Citrus is the principal one contained in it. 

 In Feronia the receptacle and perianth are analogous to those of 

 Limonia, with two verticils of stamens, double in number, or naarly 

 so, to the petals, and inserted under the hypogynous disk. The 

 ovary, with about as many cells as there are petals, to which they 

 are superposed. But in the internal angle of the cells, which are 

 often incomplete, an indefinite number of anatropous ovules are 

 observed, arranged in two vertical series, more or less descending, 

 with micropyle directed upwards and outwards. The fruit is a 

 globular berry, with ligneous rind, filled with pulp in which the 

 seeds are lodged. JEgle has all the characters of Feronia, and espe- 

 cially the multiovulate cells. But the number of these is indefinite, 

 as is the case also with the stamens. The fruit is also a corticate 

 pulpous berry. The leaves are trifoliolate, while those of Feronia are 

 imparipinnate . 



Nothing is easier to define than the genus Citrus^ (figs. 455-459) 

 when the preceding genera are known. It may be said that it
