230 FIGWORT FAMILY. 



§ 3. Corolla with lobes imbricated and not plaited in the bud, either 2-lipped or more 

 or less irregular, Ike divisions or lobes at most b. Peduncles from the axil of 

 leaves or bracts, 710 flower ever really terminating the main stem or branches. 



« Tree, with large and opposite Catalpa-like leaves. 

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

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

 lobes. Stamens 4, included. Pod turgid, thick, filled with very numerous 

 winged seeds. 



* * Herbs, or a few becoming low shrubs. 

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



6. VERB AS CUM. Flowers in a long terminal raceme or spike. Calyx 5-parted. 



Corolla with 5 broad and rounded only slightly unequal divisions. AH the 

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

 globular, many-seeded. Leaves alternate. 



-t- H- With only 2 oi' 4 anther-bearing stamens. 

 ++ Corolla wheel-shaped, or at least with wide sjireading border mostly much longer 

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

 raceme or spike. 



7. CELSIA. Like Verbascum, but with only 4 stamens, those of 2 sorts. 



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



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 threes. 



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-shnped, with almost regular 4 - 5-lobed boi'der : flowers in a 

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



10. BUCHNERA. Calyx tubular, 5-t6othed. 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 bell-shaped. 

 = Corolld 2-parted nearly to the base, Ike 2 lips snc-shaped or the lower larger one 

 slippe7--shaped : stamens only 2 {or very rarely 3), nml 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 cjones or clusters. 

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

 a flat pocket which encloses the 4 stamens and the style. 



12. COLLINSIA. CaJ^^x deeply 5-cleft. Corolla turned down ; its short tube 



laterally flattened, strongly bulging on the upper side: upper lip 2-cleft 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 interrupted raceme. 



= ==== Corolla not 2-parted nor salver-shaped, but with a tube of some length in 

 proportion to the 2-lipped or more or less irregular (i-arely neai-ly regular) 

 i- 5-lobed border, and 



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

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

 4, and no obvious rudiment. 



13. 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, lint a sac or gibbosity at the base of the personate 



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