230 FIGWOKT FAMILY. 



§ S. CdroUa with lobes imbricated and not plaited in the bud, eiiher i-lipped or more 

 or less irregular, the dindms or lobes at most 5. Peduncles from the ami oj 

 leaves or bracts, no flower ever really terminating the main stem or branches. 

 * Tree, with large and opposite Gitalpa-like leaves. 

 6. PAULOWNIA. Calyx very downy, deeply 5-cleft. Corolla deouijed, with a 

 cylindrical or funnel-form'tube, and an enlarged oblique border of 5 rounded 

 lo'bes. Stamens i, included. Pod turgid, thick, filled with very numerous 

 winged seeds. 



* * Herbs, oi- a fern becoming low shrubs'. 

 ^- With 5 anther-bearing stamens and a wheel-shaped or barely concave corolla. 

 6. VERBASCUM. Flowers in a long terminal raceme or spike. Calyx 5-parted. 

 Corolla with B broad and rouncied only slightly unequal divisions. All the 

 filaments or 3 of them woolly. Style expanding and flat at apex. Pod 

 globular, many-seeded. Leaves alternate. 



H- H- With only 2 or 4 anther-bearing stamens. 

 ++ Corolla wheel-shaped, or at least with wide spreading bmder mostly much longer 

 than the short tube : flowers single in the axils of the leaves or collected m a 

 raceme or spike. 

 t. CELSTA. Like Verbascum, but with only 4 stamens, those of 2 sorts. 



8. ALONSOA. Calyx 5-parted. Corolla very unequal, turned upside down b^ 



the twisting of the pedicel, so that the much larger lower lobe appears to be 

 the upper and the two short upper lobes the lower. Stamens 4. Pod many- 

 seeded. Lower leaves opposite or in thi-ees. 



9. VERONICA. Calyx 4-parted, rarely 3 -5-parted. Corolla wheel-shaped, or 



sometimes salver-shaped, with 4 or rarely 5 rounded lobes, one or two of 

 them usually rather smaller. Stamens 2, with long slender filaments. Pod 

 flat or flattish, 2 - many-seeded. At least the lower leaves opposite or some- 

 times whorled. 

 ++ ++ Corolla salver-shaped, with almost regidar 4 - 5-lobed border ; flowers in u 

 terminal spike. Here one species of No. 9 would be sought. 



10. BUCHNERA. Calyx tubular, 5-toothed. Corolla with a slender tube, and 



the border cleft into 5 roundish divisions. Anthers 4 in 2 pairs, one-celled. 

 Style club-shaped at the apex. Pod many-seeded. Leaves mainly opposite, 

 roughish. 



++++++ Corolla either obviously 2-lipped, or funnel-form, tubular, or beU-shaped. 

 = CoroU'i 2-parted nearly to the base, the 2 lips snc-shnped or the lower liirger one 

 slipper-shaped: stamens only 2 [or very rarely 3), and no rudiments of more. 



11. CALCEOLARIA. Calyx 4-parted. The two sac-shaped or slipper-shaped 



divisions of the corolla entire or nearly so. Pod many-seeded. Leaves 

 chiefly opposite, and flowers in cymes or clusters. 

 = = Corolla almost 2-pnrted, the middle lobe of the lower lip folded together to form 

 aflat pocket which encloses the 4 stamens and the style. 



12. COLLINSIA. Calyx deeply S-cleft. Corolla turned down ; its short tube 



laterally flattened, strongly bulging on the upper side; upper lip 2-oleft and 

 turned back; the lower one larger and 3-lobed, its middle and laterally 

 flattened pocket-shaped lobe covered above by the two lateral ones. A little 

 rudiment of the fifth stamen present. Pod globular, with few or several seeds. 

 Flowers on pedicels single or mostly clustered in the axils of the upper oppo- 

 site (rarely whorled) leaves, which are gradually reduced to bracts, forming 

 an intermpted raceme. 



^ = := Corolla not 2-parted jior salver-shaped, but vnth a tube of some length in 

 propwtion to the 2-hpfted or more or less irregular (rarely nearly regular) 

 i-b-lobed border, and 



a. With a spur or sac-like projection at the base on the lower side, and a projecting 

 palate to the Imoer lip, which commonly closes the throat or nearly so : stamens 

 4, and no obvious rtuliment. 



18. LINARIA. Calyx 5-parted. Corolla personate, and with a spur at base. 

 , (Lessons, p. 102, fig. 211.) Pod many-seeded, opening by a hole or chink 



which forms below the summit of each cell. 

 14. ANTIRRHINUM. No spur, but a sac or gibbosity at the base of the personate 



coroUa (Lessons, p. 102, fig. 210): otherwise like 13.
