 filaments 5, on the corolla ; ovary smooth, short-stiped ; style filiform • 

 stigmas 2, each 2-parted, and with the anthers dimorphous, i. e, in 

 some plants the stamens exceed the stigmas, iu others the stigmas ex- 

 ceed the stamens, as in Houstonia; capsule twin, compressed, with a very 

 narrow dissepiment (or ?), valves each 2-cleft at top, cells few (4 to 6)- 

 fieeded, seeds winged. — Shrub slender, smooth, climbing, with evergreen 

 Ivs. and large, showy yellow fils. Stip. reduced to a raised rim. 



Or. sempervirens Ait "Woods and banks of streams, Va. to Ala. and Fla., very 

 abundant. A slender vine, twining and overrunning bushes and low trees, and 

 profusely flowering. Lva. coriaceous, shining, revolute at edge, lanceolate, acute 

 at each end, short-petioled. Cor. tube 1' long, of a rich golden yellow. In one 

 variety the stamens equal the corolla and the style but half as long ; in the other

Order LXXXVI. SCROPHULARIACEiE. Figworts. 



Herbs cliiefly, without fragrance, tlie leaves and inflorescence various. Flowers 

 irregular, 5-merous, didynamous or diandroua (rarely peutandrous). Calyx free from 

 the ovary, persistent. Corolla, monopetaloua, imbricated in bud. Stamens inserted 

 in the tube of the corolla, 1 or 3 of them usually rudimentary. Ovary free, 2-ceUed, 

 with 1 style, a 2-lobed stigma, and becoming in frait a, 2-celled, many-seeded cap- 

 sule, with axile placentae. Seeds albuminous., (Fig. 204, 326, 362, 399, 427, 463.) 



Oenera ISO, species 1800, abundant in every part of tlio wovld, from the equator to th« 

 regions of perpetual frost. They constitute about 1-36 of tbe PbEenogamia of N. America. 



Properties. — Generally acrid, bitter and dtletorioad plants. The most remarkable officinttl 

 species of the tribe is the Foxglove (Digitalis), "which exercises a wonderful control over tbe 

 motion of the heart, in regulating its pulsations. Ic is also employed in cases of dropsy, hemor- 

 rhage. &c. Taken in excess it speedily causes death. The Veronica Virginica (Culver's Phyaic) 

 and Linaria vulgaris (Toad-flax) are purgative a|^ emetic. Numerous species are cultivated for 

 ornament. Many areparasUic and turn black in drying.
