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



1. PATTLOWNIA. Calyx very downy, deeply 5-cIeft. Corolla decurved, with a cylindrical 



or funnel-form tube, and. an enlarged oblique border of 5 rounded lobes. Stamens 

 4, included. Pod. turgid and top-shaped, tilled with very numerous winged seeds. 



* * Herbs, or a few becoming low shrubs. 

 +- Anther-bearing stamens 5, and a wheel-shaped or barely concave corolla. 



2. 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 8 of 

 them woolly. Style expanding and flat at apex. Pod globular, many-seeded. Leaves 

 alternate. ^_ ^_ ^ TC £ft er _& ear ^jr stamens only 2 or 4. 



++ Flower with corolla wheel-shaped, or at least with wide spreading border mostly 

 much longer than the short tube; flowers single in the axils of the leaves or col- 

 lected in a raceme or spike. 



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



4. ALONSOA. Calyx 5-parted. Corolla very unequal, turned upside down by the twist- 



ing of the pedicel, bo 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. 



5. VERONICA. Calyx 4-parted, rarely 8-6-parted. Corolla wheel-shaped, or sometimes 



salver-shaped, with 4 or rarely 6 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 sometimes whorled. 



++ ++■ Flower with corolla salver-shaped, with almost regular 4-5-lobed border ; flowers 

 in a terminal spike. Sere one species of No. 5 might be sought. 



6. BUCHNERA. Calyx tubular, 5-toothed. Corolla with a slender tube, and the border 



cleft into 5 roundish divisions. Anthers 4 in 2 pairs, 1-celled. Style club-shaped 

 at the apex. Pod many-seeded. Leaves mainly opposite, roughish. 



++■»+++ Flower with corolla either obviously flipped, or funnel-form, tubular or belU 



— 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. 



1. 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-parted, the middle lobe of the lower lip folded together to form 

 aflat pocket which incloses the 4 stamens and the style. 



8. COLLINSIA. Calyx deeply 5-cleft. Corolla turned down, its short tube laterally 



flattened, strongly bulging on the upper side ; upper Up 2-cleft and turned back ; the 

 lower one larger and 8-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 pedicelB single or mostly clus- 

 tered in the axils of the upper opposite (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 pro- 

 portion to the 2-lipped or more or less irregular (rarely nearly regular) 4-5- 

 lobed border. 



I A spur or sac-like projection at 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, 



9. LINARIA. Calyx 5-parted. Corolla personate, and with a spur at base. (Lessons, 



Fig. 258.) Pod many-seeded, opening by a hole or chink which forms below the 

 summit of each cell.
