FIGWORT FAMILY. 319 



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



1. 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 and top-shaped, filled 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-par ted. 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. ^ _,_ ^ n ther-bearing stamens only 2 or 4. 



H- 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. 



3. 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, 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. 



5. 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 sometimes whorled. 



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

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



6. BTJCHNERA. 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. 



H- -H- -H- Flower with corolla either obviously 2-lipped, or funnel-form, tubular or bell- 

 shaped. 



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. 



t 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 ^-parted, the middle lobe of the lower Up 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 lip 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 pedicels 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 ^-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 tpur 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.
