RUSH FAMILY 117 
1. H. reniformis,R. & P. (Fig. 7, pl. 3.) Mup Prantain. Leaves 
kidney-formed. Flowers 2 to 5 in a cluster, white or pale blue. Mud in 
shallow borders of ponds and streams. Conn., westward. 
2. H. dubia, (Jacq.) MacM. (Fig. 6, pl. 3.) Water Star Grass. 
Leaves grass-like. One flower only arising from the spathe, yellow. In 
still water or in the muddy borders of streams. In our whole region. 
Order VI.—LILIIFLORAE. Order of Lily-like Flowers 
Perianth (except in Iris and Trillium) of 6 similar parts, 
usually all colored. In Juncaceae the parts are dry, greenish or 
brown, scales or glumes, and in Muscari, Aletris and a few others 
the divisions are more or less united. The divisions are arranged 
in an outer and an inner row, the outer in fact representing the 
calyx. In Trillium the segments of the outer row are green sepals. 
The divisions are, however. in other genera generally structurally 
similar and all have the appearance of petals. The anthers face 
toward the inside of the flower. 
In the Iris and Bloodwort families 3 stamens are suppressed 
and in the Iris itself 3 petals are less in size than the other 3, while 
the 3 styles are so expanded and colored as to resemble petals. 
There are, therefore, with the exceptions mentioned, 6 petals, and 
in all our species, 6 stamens and 1 or 3 pistils, the latter surmount- 
ing an ovary divided into 3 cells, the ovary being situated above 
the stamens and perianth in some families and below in others. 
In general the leaves are long and narrow with parallel veins. 
In most of the berry-bearing species the leaves are broadened and 
in the plants with twining or woody stems the leaves are decidedly 
broad, often oval or even round. This fact holds also with 
Trillium. 
The order is an extensive one, including Rushes, the onion-like 
Alliums, the Hyacinths, Smilax and other tribes besides the true 
Lilies. 
1. Flowers with dry, chaffy perianth (glumes) similar to that 
of the grasses, sedges, etc., but with the general structure 
of Liluflorae . . . . . RusH Famity JUNCACEAE
