Descriptive Flora 



Viola langloisii Greene. White Violet. 



Similar to Viola missouriensis but differs in that many of 

 the leaves of this violet broaden after flowering, become broadly 

 triangular with two long, almost divergent lobes. Others are 

 triangular heart-shaped. Flowers white or a very pale violet, 

 on peduncles longer than the leaves. Capsules pale yellow faint- 

 ly dotted with purple. March and April. Shaded river bottoms. 

 The cultivated pansy is a hybrid of several wild species of 

 violets. 



Calceolaria verticillata (Ortega) Kuntze. Green Violet. 



Much branched plants, with alternate, entire leaves about 1" 

 long, and small, inconspicuous, apparently 2-lipped, purplish 

 flowers on slender pedicels in the axils of each leaf. Stems 

 densely covered with very short hairs. Leaves simple, alternate. 

 Blades 1-nerved, broadly linear above, tapering at both ends. 

 Lobes of calyx 5, as long as the upper petals. Corolla apparently 

 2-lipped. Lower lip, y s " long, at least twice as long as the 

 upper, consisting of one greenish, violet-tipped, slightly con- 

 cave petal. Seed pod small, 3-sided, 1-celled, containing about 5 

 seeds. Blossoms among the smallest of the simple axillary flowers. 

 Fairly common but not noticed because of the inconspicuous 

 flowers. Genus has its origin in the Lat. calceolus, tiny shoe, 

 from the shape of the corolla. 



PASSIFLORACEAE. Passion Flower Family. 

 Passiflora incarnata L. Passion Flower. Maypop. 



Vine-like plants climbing by tendrils and having large, 

 purplish fringed flowers. Leaves simple, alternate. Leaf-blades 

 large, 2 to 6 inches broad, 3-lobed, on long petioles. Flowers 

 lavender to purplish, showy, over 2 inches across, solitary on 

 long stalks in the axils of the leaves. Very rare. Seen once at 

 Brackenridge Park.
