The narrow long leaf is like a grass-blade, with an entire margin, fine texture, and smooth surface. It is pale gray-green, lighter underneath. The leaves are set close on the stalk, the arrangement being alternate, and near together. The flower is 2-lipped; the lower lip is 3-lobed, the middle lobe being short and small, with a swelling above, which nearly closes the throat of the corolla; the base of the lip is prolonged into a slender, pointed spur; the upper lip is 2-lobed, the divisions bend outward and over the lower lip; the texture is fine, and smooth, the throat being lined with a glossy plush-like down; the color is a pure lemon yellow, the protuberance on the lower lip golden-orange. The 4 stamens are pale with cheese-colored tips; the pistil is tipped with green. The small calyx is 5-parted, and green. The flowers, on short small foot-stems, are arranged alternately, and close, in a terminal spike, the spurs turning downward. A charming feature of the blossom is the arch of the meeting tips of the long pair of stamens above the shorter pair and the little pistil; the two rows of orange velvet that run down the inside of the corolla are also highly ornamental. This plant is a prime favorite with children, but few among grown observers stop to consider the admirable clarity of its lemon and orange hues. It is gregarious and grows in colonies. [Illustration: BUTTER-AND-EGGS: Linaria vulgaris.] *Wild Toad Flax.* _Linaria Canadensis._ Found on sandy barrens during August and September. The very slender and delicate stalk (from 10 to 12 inches in height) branches a little; its leafage is sparse, and it is very smooth and shining. In color light green. The small leaf is narrow and fine-pointed, with an entire margin; the texture is rather thick, and the surface is smooth; light green. The leaves are set upon the stalk alternately, and at regular intervals. The small flower is 2-lipped, with a spur; the upper lip is divided into 2 sharp little points, the lower lip is larger and cut into 3 rounding scallops,--it presses against the upper with a prominent swelling near the throat of the corolla, the curving spur is thread-like; the texture is thin, and the color is a delicate lavender, with a white spot on the under lip; the calyx is 5-parted, and green. The flowers are set on short fine stems in a dainty terminal spire. The stalk springs from a little mat of very leafy shoots, which lie on the ground, spreading outwards from the root. In color and general trigness of bearing this pretty plant presents a superficial resemblance to the Lobelias. [Illustration: WILD TOAD FLAX: L. Canadensis.] *Cow Wheat.* _Melampyrum Americanum._ Found on the borders of light woods from July to September. The stalk is 4 to 6 inches,--or perhaps more,--high; it is branching, leafy, woody-fibred, and slightly rough to the touch. In color, reddish-gray.
