« Tree, with larpe and opposite Catdlpa-lile leaves. 



1. PAULOWXIA. Calyx very downy, deeply 5-cleft. Corolla dccurved, with a cylindrical 



or funnel-fonn tube, and an enlarged oblique border of o rounded lobes. Stamens 

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

 * * Herbs, or a few becoming low shrubs. 

 +- Anther-bearing niameits .">, ami a loheel-shaped or bai-ely concave corolla. 



2. VEKBASCr.M. Flowers in a long- terminal raceme or spike. Caly.\ 6-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 

 a eina e. ^ ^ Anther-bearing stamens onlg 2 or 4. 



++ Flower ivith corolla wheel sliaped, or at least with wide spreading border nwsthj 

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

 lected ill a raceme or spike. 



3. CELSIA. Like Verbaseum, but with only 4 stamens, those of 2 sorts. 



4. ALONSOA. Caly.x 5-parted. Corolla very uneijual, 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. VEKONICA. Caly.x 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 flatfish, 2-many- 

 seeded. At least the lower leaves opposite or sometimes whorled. 

 ++ ++ Flotcer ivith corolla salver-shaped, with almost regular i-U-lobed border ; Jlowers 

 in a terminal spil:e. Here one species of No. 5 might be souglit. 



6. BUCHNERA. Caly.x 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 ivith corolla either obviously i lipped, or funnel-form, tubular or bell- 

 shaped. 



-= Corolla 1-parted nearly to the base, the 2 lips sac-shaped or the lotver larger one 

 sHppershaped ; stamens only 2 {or very rarely •■',), and no rudiments of more. . 



7. CALCEOL.\KL\. Calyx 4-parted. The two sac-shaped or slijiper-shaped divisions of 



the corolla entire or nearly so. Pod many-seeded. Leaves chiefly opposite, and 

 flowers in cymes or clusters. 

 == = Corolla almost 2-parfed, the middle lobe of the loiver lip folded together to form 

 aflat pocket which incloses the 4 stamens and the style. 



8. COLLINSLV. Calyx deeply 5-cloft. 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 clus- 

 tered in the axils of the upper opposite (rarely whorled) leaves, which are gradually- 

 reduced to bracts, forming an interrupted raceme. 



=. -= = Corolla not ■I-parted nor salver- shaped, but with a tube of some length in pro- 

 portion to the 'llipped or more or less irregular (rarely nearly regular) 4-5- 

 lobed border. 



E 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 rudi)nent. 



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



Fig. 25S.) Pod many-seeded, opening by a hole or chink which forms below the 

 summit of each cell.
