San Juan Tree—Nicotiana glauca.
Desert Matrimony—Lycium Cooperi.
FIGWORT FAMILY. Scrophulariaceae.
A large family, widely distributed, most of them natives of temperate regions; chiefly herbs, with bitter juice, sometimes narcotic and poisonous; without stipules; the flowers usually irregular; the calyx usually with four or five divisions, sometimes split on the lower or upper side, or on both sides; the corolla with united petals, nearly regular or two-lipped, two of the lobes forming the upper lip, which is sometimes beaklike, and three lobes forming the lower lip; the stamens on the corolla and alternate with its lobes, two or four in number, two long and two short, and sometimes also a fifth stamen which often has no anther, the anthers two-celled; the ovary superior, usually two-celled, the style slender, the stigma sometimes forked; the fruit a pod, splitting from the top into two parts and usually containing many seeds. This is a curious and interesting family, its members very dissimilar in appearance, having expressed their individuality in many striking and even fantastic forms.
There are several kinds of Maurandia, perennial herbs, climbing by their slender twisted leaf-stalks and occasionally also by their flower-stalks; the leaves triangular-heartshaped or halberd-shaped, only the lower ones opposite; the flowers showy, purple, pink, or white; the corolla with two lines or plaits, instead of a palate, which are usually bearded.
Snap-dragon Vine
Maurándia antirrhìniflora
(Antirrhinum maurandioides)
Purple or pink and yellow
Spring
Ariz., New Mex.
This is a beautiful trailing or climbing vine, smooth all over, with charming foliage and twining stems, much like those of a Morning-glory, springing from a thickened, perennial root. The pretty flowers are over an inch long, with a purple or raspberry-pink corolla, with bright yellow blotches on the lower lip, forming an odd and striking combination of color. This blooms all through the spring and summer and may be found growing in the bottom of the Grand Canyon, near the river, where its delicate prettiness is in strange contrast to the dark and forbidding rocks over which it clambers and clothes with a mantle of tender green.
Snap-dragon Vine—Maurandia antirrhiniflora.
There are many kinds of Antirrhinum, natives of Europe, Asia, and western North America; herbs; the lower leaves often opposite, and the upper ones alternate; the sepals five; the corolla two-lipped, swollen at the base on the lower side, but with no spur, the palate nearly closing the throat; the stamens four. The name is from the Greek, meaning "nose-like," because the shape of the flowers suggests the snout of an animal.
