MACLOSKIE: SCROPHULARIACE^. 713 



rigid, spreading, apically truncate leaves. Leaf-bases dilated to a pericla- 

 dium, concave ventrally, costate-carinate dorsally. Flowers long-exsert 

 from the upper axils; sessile, solitary, 2-bracted. Calyx short (3 mm.), 

 5-cleft, the lobes as long as the tube. Corolla tubular, white, 8 mm. by 

 1.5 mm. 

 S. Patagon., by Rio Sta. Cruz. 



5. BENTHAMIELLA PYCNOPHYLLOIDES Speg. 



Cespitose. Leaves minute, ovate-scaleform, densely imbricate, entire, 

 apically thick, green, acute, basally dilated, and with woolly edge. 

 Flowers long, exserted from upper axils, sessile, solitary, 2-bracteolate. 

 Calyx-lobes equalling the tube. Corolla pale-violascent, twice as long as 

 the calyx.

Family 100. SCROPHULARIACE^E. Snapdragon Family. 



Herbs, shrubs or trees, with exstipulate leaves and perfect, sympetalous, 

 mostly zygomorphic flowers. Stamens epipetalous, mostly 4 and didyna- 

 mous, sometimes only 2, rarely 5. Ovary superior, 2-celled (rarely i- 

 celled), the cells being antero-posterior, with axial placentae. Style i, 

 often apically 2-lobed. Fruit capsular. Seeds numerous, endospermous. 



Species 2,300, chiefly in temperate climates. 



KEY TO THE GENERA. 



A. The 2 dorsal corolla-lobes (or by their fusing the upper lip), cover the lateral lobes in the 

 bud. Basal leaves or all opposite. Fifth stamen changed or none. (ANTIRRHINOIDEJE.) 

 b. Corolla 2-lipped, the lips urceolate, concave. Stamens 2, dehiscing by slits. 



I. Calceolaria, p. 714. 

 62. Corolla regular or 2-lipped, its lips flat or convex. Fruit a many-seeded capsule. 



c. Corolla spurred, having a tube and a palate nearly closing the throat. Flowers ter- 

 minally racemed or spicate. 2. Linaria, p. 719. 

 C2. Corolla not spurred, nor basally saccate. Inflorescence usually simple. Stamens all 

 inserted in the corolla-tube ; anthers 2-celled. Calyx 5 -toothed or 5 -cleft. Capsule 

 4-valved. 

 d. Capsule loculicidal. Stigma capitate. Seeds large, few. Erect shrubs. Leaves 



few, often reduced. 3. Monttea, p. 719. 



d,2. Capsule loculicidal and septicidal. Seed-ridges free or coalescing. Anther-cells 



partly fused. Herbs, woolly or glandular. 4. Stemodia, p. 719. 



^3. Corolla regular. Calyx 5-parted, its dorsal lobe longer or broader than the others. 

 Anther-cells touching or ultimately fusing. 5. Monnicra (Bacopd), p. 720.
