filaments dilated below, and two ovules in each cell; Zuvunga, 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 Afalantia and Paramygnia, 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 Paramygnia, 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 
Citree, 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 nearly 
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. ÆZyle has all the characters of Merona, 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 Feroniu are 
imparipinnate. 5 
Nothing is easier to define than the genus Cifrus' (figs. 455-459) 
when the preceding genera are known. It may be said that it
