324 THE SCKOPHULAKIA FAMILY. [Verbasoum. 



Calyx inflated after flowering. Upper lip of the corolla 



laterally compressed 13. PEDICULARIS. 



Calyx tubular or campanulate. Upper lip of the corolla 



with 2 spreading lobes 11. EUPHRASIA. 



Calyx with 4 lobes or teeth. 

 Upper lip of the corolla arched or with spreading lobes. 



Anther-cells pointed at the lower end. 



Upper lip of the corolla nearly entire, arched or concave 10. BARTSIA. 

 Upper lip of the corolla 2-lobed, spreading . . .11. EUPHRASIA. 

 Upper lip of the corolla much compressed laterally. 



Anther-cells obtuse. 



Calyx much inflated, the teeth small . . . .12. RHINANTHUS. 

 Calyx tubular or campanulate, toothed or lobed . . 14. MELAMPYRUM. 



These British genera belong to two of the three principal Tribes or 

 Suborders of the family, viz : 



Tribe Antirrhinece. Upper lip or outer lobe of the corolla outside the others in 

 the bud. Genera: 1. VERBASCUM; 2. ANTIRRHINUM; 3. LINARIA; 4. SCROPHU- 

 LARIA ; and 5. MIMULUS. 



Tribe JRhinanthece. Upper lip or upper lobe of the corolla wholly or partially 

 inside the others in the bud. Genera : 6. LIMOSELLA ; 7. SIBTHORPIA ; 8. DIGI- 

 TALIS; 9. VERONICA; 10. BARTSIA; 11. EUPHRASIA; 12. RHINANTHUS; 13. PEDI- 

 CULARIS ; and 14. MELAMPYRUM. 



Among the exotic genera cultivated in our gardens may be mentioned, 

 BrowaUia, Brunsfelsia, Salpiglossis, and Schizanthus, belonging to the 

 wholly exotic tribe Salpiglossidece, now generally transferred to Solanacece; 

 and Calceolaria, Alonsoa, Angelonia, Maurandia, Lophospermum, Pau- 

 lownia, Collinsia, Pentstemon, Torenia, and several others of the tribe 

 Antirrhinece. The exotic genera of Rhinanthece, with the exception of a 

 few allied to Veronica and Digitalis, are mostly parasitical, and there- 

 fore, although very handsome, not in cultivation. The south-west 

 European Erinus alpinus, allied to Veronica, but with a 5-lobed corolla 

 with a slender tube, is established as an escape from gardens, on old 

 walls, especially on the Koman Wall, on the borders of Yorkshire and 

 Lancashire. 



I. VERBASCUM. MULLEIN. 



Tall, erect, stiff herbs, often woolly ; with coarse, alternate leaves, 

 more or less toothed; and yellow, white, or rarely purple flowers, 

 either solitary under each bract or in short dense cymes or branches, 

 forming terminal, simple spikes or branched panicles. Calyx deeply 

 5-clef t. Corolla rotate, or concave, with a very short tube, and 5 broad, 

 rounded lobes. Stamens 5, with all the filaments woolly or the two 

 lower ones glabrous. Capsule ovoid, opening at the partition in 2 

 valves, with very numerous small seeds. 



The genus extends over Europe and northern and central Asia, but is 

 most abundant in the Mediterranean region, where the species vary 

 much, besides frequently producing natural hybrids, so that their 

 distinction has become very complicated. [In the case of the British 

 species, V. nigrum hybridises with Tkapsus, pulverulentum, and Lychnitis, 

 and V. Thapsus with Lychnitis.] 



Leaves decurrent on the stem, very woolly. Flowers in a 



dense, simple spike 1. F. Thapnu. 



Leaves not decurrent, or the upper ones very slightly so. 



Flowers in a raceme or panicle. 



Plant glabrous or slightly glandular-hairy. Two stamens 

 longer than the others, with long anthers. Flowers
