number of ornamental plants and some troublesome weeds. The 
flowers are regular and perfect with a 5-lobed calyx, a more or 
less 5-lobed corolla, 5 stamens, and 1 pistil with a single style and 
stigma. The family is represented here only by Solamim triflorum, 
a low, much-spreading herb with alternate leaves. The leaves are 
oblong but pinnately deeply lobed. The small, white flowers are 
produced singly or two or three together. The stamens have very 
short filaments, and the anthers are crowded around the style in 
such a way as to form a cone. The fruit is a green berry. 
The genus Solarium is commonly known as nightshade. 
EIGWOKT FAMILY (SCROPHULAKIACEAE) 
This is a large family and contains many plants with ornamental 
flowers but no important food or other economic plants. The sepals 
are united to form a toothed or lobed calyx, and the petals are also 
united to form a more or less irregular, often distinctly two-lipped 
corolla. There are usually either 2 or 4 stamens, but in some cases 
there are 5, and the ovary of the single pistil is not lobed as it is 
in the mint and borage families. In many cases when there are 5 
stamens, 1 of them is sterile.

Owlclover (Orthocarpus luteus) _(p. 113) 
Kittentails (Synthyris Wyoming ensis) grows 4 to 10 inches high. 
The leaves are mostly basal, those on the stem being small and ses¬ 
sile. The flowers have no corolla and, therefore, are not colorful, 
but the stamens, being twice the length of the calyx, are conspicuous. 
Speedwell (Veronica ).—Low plants with mostly opposite leaves 
and small blue or whitish flowers. Five species are found in the park 
and may be distinguished as follows:
