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

 &r less irregular, the divisions or lobes at most 5. Peduncles /"rum the axil of 

 leaves or bracts, nofiowtr ever really terminating the main stetn or branches. 

 # Tree, with large and opposite Cutalpa-lihe 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 i, included. Pod turgid, tnick, filled with very numerous 

 winged seeds. 



* * Herbs, or a feu) becoming low shrubs. 

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



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



Corolla with 5 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. 



■1- H- With only 2 or i anilier-beanng stamens. 

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

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

 raceme or spike. 



7. OELSIA. Like Verbasoum, 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 thiit 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 



sonxetinxes salvei^shaped, with 4 Qr rarely 5 rounded lobes, one or two of 

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

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

 times whorled. 

 ++ ++ Corolla salver-shaped, with almost regular 4 - 5-lobed border : foioers 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. 



H-n-n-t- Corolla either obviously 2-lipped, or funnel-form, tubular, or bell-sliaped. 

 = Corolla 2-parted nearly to the base, the 2 lips sac-shaped or the lower larger 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 alriwst 2-parted. the middle lobe of the lower lip folded together to form 

 aflat pocket which encloses the 4 stamens and tlie style. 



12. COLLTNSIA. Calvx deeply 5-oleft. Corolla turned down ; its short tube 



laterally flatteneil, strongly bulging on the upper side: upper lip 2-cleft and 

 turned back; the lower one larger and S-lobod, its middle and laterally 

 flattened pocket-shaped lobe covered above by the two lateral onci. 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, fornung 

 an internipted raceme. 



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

 proportion to ike 2-lipped or more or less irregular {rarely nearly regular) 

 4 - 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 linoer Up, 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, but a sac or gibbositv at the base of tlie personate 



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