230 FIGWORT FAMILY. 



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

 or less irregular, the divisions or lobes at most 5. Peduncles from the axil <// 

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



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



6. PAULOWNIA. Calyx very downy, deeply ">-elet't. 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. 

 - 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 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. 



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



f Corolla tcheel-sh<i/il, < a/ lia^t with widi' spn-nding border mostly much longer 

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

 raceme or spike. 



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



8. ALOXSOA. Calyx ">-partrd. Corolla very unequal, turned np-ide down hy 



the twisting of the pedicel, so that the iniieh 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 i:i t! 



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. 1'od 

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

 times whorled. 



*+ *-*. Coi'olla safrer-slriped, with alnwst regular 4 - 5-lo/jcd border: flowers in a 

 terminal spike. Here one species of Xo. would be. sought. 



10. BUCHNERA. Calyx tul.ular, r,-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.-M. Corolla either obrioiigfy 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 rery 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. Tod many-seeded. Leaves 

 chiefly opposite, and flowers in cymes or clusters. 



= = Corolla almost 2-p-trted. (he middle lbe of the lower Up folded together to form 

 aflat i>ocket 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 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 salrcr-diaped, bid with, a tube of some length in 



proportion to the 2-l/pped or more or less irregular (rarely nearly regular) 



4-5-lobed border, and 

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



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



4, and no obvious rudiment. 



13. LIN ARIA. Calyx 5-parted. Corolla personate, and with a spur at rne. 



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

 winch forms below the summit of each cell. 



1 1. ANTIRRHINUM. No spur, but a sac or gibbosity nt the base of the personate 

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