230 FIGWORT FAMILY. 



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

 or less ii-regular, the divisions or lobes at most 5. Peduncles from the axil of 

 leaves or bracts, nofl&toer ever really terminating the maim stem or branches. 

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

 6. PAULOWNIA. Calyx very downy, deeply 5-oleft. Corolla deourved, with a 

 cvllndrical 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. 

 4- With 6 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 6 broad and rounded only slightly unequal divisions. All the 

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

 globular, many-seeded. Leaves alternate. 



^- ^- Willi only 2 or 4 anther-bearing stamens. 

 ** Corolla wheel-shaped, or at least with wide spreading border mostly much longer 

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

 raceme or spike. 

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



8. ALONSOA. Calyx 5-parted. Corolla very unequal, turned upside down t>y 



the twisting of the pedicel, so that the much lai-ger 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. 

 ++ 4H. Corolla salver-shaped, with almost regular 4 - B-lobed bo7'der : fiowers in a 

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



10. BUCHNERA. Calyx tubular, 6-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 funnelform, tubular, or bell-shaped. 

 = Corolla 2-parted nearly to the base, the 2 lips sac-shaped or the lower larger one 

 sUpper-shaped : stamens only 2 {or very rarely 3), and no I'udiments 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 Jn cymes or clusters. 

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

 a fiat pocket which encloses the 4 stamens and the style. %- 



12. COLLINSIA. Calyx deeply 5-cleft. Corolla turned down ; its short tube 



laterally flattened, strongly bulging on the upper side: upper lip a-cleft and 

 turned back; the lower one larger and 3-loDed, 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 (rarely nearly regular) 



i-b-lobed border, ami 

 Bu With a spur or sac-like pryection at the base on the lower side, and a pi-ojeclmg 



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



4, and no obvious rudiment. 



13. LINABIA. Calyx 5-parted. Corolla personate, and with a spur at base. 



(Lessons, p. 90, fig. 258.) Pod many-seeded, opening by a hole or chink 

 which forms below the summit of each oeU. 



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



corolla (Lessons, p. 90, flg. 257): otherwise like 13.
