4 NATURAL HISTORY OF PLANTS. 
Agelea,' formerly confounded with Connarus, is only distinguished 
from it by characters of very slight importance. The leaves are 
always trifoliolate ; the calyx persists around the fruit, without, how- 
ever, being closely applied, as in Connarus, to its foot, which is here 
shorter, or even quite wanting. The petals and stamens offer several 
variations in form and size. 
To the genus Agelea botanists are generally agreed in adding 
Hemiandrina, which consists of plants from India and the Indian 
Archipelago, whose flowers are usually trimerous or tetramerous, and 
only rarely pentamerous, with the petals narrow.and elongated, and 
the sepals valvate, or scarcely imbricate in the bud.* Thus consti- 
tuted, the genus Agelea consists of half a score species* from the 
tropical regions of the Old World, namely, Guinea, Madagascar, 
India, and the Indian Archipelago. They are bushy shrubs, erect 
or climbing, with trifoliolate leaves, whose lateral leaflets are un- 
symmetrical, and with usually numerous flowers in axillary or lateral 
ramified racemes of cymes. 
Rourea (Fr., Rourelle), with all the floral characters of Conzarus, 
differs from it in the two following points :—The carpels, variable in 
number, which go to form the fruit, are sessile instead of possessing 
a slender foot ; and the calyx begins enlarging around them from the 
moment the fruit sets, so as to hide it more or less completely. 
About two score species are known, trees or shrubs (sometimes 
climbing) from tropical Asia,’ Africa,’ and America.’ The leaves are

3 J. Hooxer has made use of these variable 
characters to split up dAgelea into five sections, 
characterized as follows:—‘“1. Petala libera. 
Slamina 5 libera inclusa.—2. Petala libera. 
Stamina 10 basi breviter connata exserta, 
Ovaria 5.—3. Petala leviter connata. Stamina 
10 basi connata exserta. Ovaria 5.—4, Petala 
libera. Stamina 5d libera; filamentis sepe apice 
recurvis ; antherarum loculis demum confluen- 
tibus. Ovaria 3~-5.—5. Petala libera, Sta- 
mina 10 libera; antheris recarvis extrorsum 
spectanlibus (Hemiandrina).”
