Famity II.—LIMNANTHACEAE. Fatse Mermaip FAMILY 
Herbs, with alternate compound leaves, without stipules. Sta- 
mens few (6 to 10), twice as many as the petals. Sepals and 
petals equal in number. Carpels equal in number to the stamens, 
uniting in a single style, which above, is cleft into as many stigmas 
as there are carpels. 
FLOERKEA, Willd. 
Small plant with compound feather-formed leaves (about 2 pairs of 
leaflets and an odd one), growing in marshes and on river and lake banks. 
Sepals usually 3, longer than the 3 oblong petals. 
F. proserpinacoides, Willd. (Fig. 4, pl. 89.) Farse Mermarp. A 
small slender plant growing in marshes and on river banks. Stems about 
1 ft. long prostrate or partly submersed. Leaves of 5 leaflets, those sub- 
mersed of three leaflets or divisions. Flowers, in the leaf axils, white. 
Fruit one or two globular carpels. 
Faminty IIT—ANACARDIACEAE. Sumac Famity 
Trees or shrubs, with resinous milky acrid juice, with alternate 
compound leaves in our species; flowers which may be perfect, but 
which often contain either stamens only or pistils only. Calyx, 
and corolla usually each of 5 members. Stamens usually 10 or 
twice the number of the sepals, but by suppression the number 
may be reduced to 1. Ovary 1- to 4-celled, 1-seeded. Styles 1 to 
3 but, when 1, divided into 3 stigmas at top. Fruit a pulpy berry- 
like drupe with hard seed-coats. Of the family we have but one 
genus. 
RHUS, L. (Toxicodendron, Mill.) 
Trees, shrubs and woody vines. Leaves mostly compound. Flowers 
usually small, in dense clusters. Fruit small with a central strong seed.

Sumac. Small tree or shrub. Branches and leaf-stalks silky. Leaves 
of 4 to 10 pairs of leaflets with an odd one. The common leaf stalk 
broadens, betweens the leaflets, into a wing on each side which differen- 
tiates it from all the other species'of Rhus. It is usually a low shrub 
or tree, but may rise to a height of 20 or even 30 ft. The cluster of flowers
