610 THE SCEOPHULARIA FAMILY. 



III. LINARIA. LINAEIA. 



This genus only differs from Snapdragon in the tube of the corolla, 

 which is projected at the base into a conical or cylindrical spur. The 

 species are more numerous, and the geographical range rather wider, 

 but still the greater number are from southern and especially south- 

 western Europe. 



Stems erect or ascending. Leaves linear, oblong or rarely 

 ovate, entire. 

 Flowers yellow. 



Stems 1 to 3 feet high, erect from the base .... 1. Common L. 

 Stems scarcely 6 inches high, diffuse at the base . . 4. Supine L. 

 Flowers blue or purplish or striped. 



Perennial. Flowers on short pedicels, in terminal 



racemes. Spur short and conical 2. Pale L. 



Annual. Flowers on short pedicels, in a short ter- 

 minal raceme. Spur long and slender .... 3. Pelisser's L. 

 Annual. Flowers small, on long axillary pedicels. 



Spur short and conical 5. Lesser L. 



Stems trailing. Leaves ovate, orbicular, or angular. 

 Plant quite glabrous. Leaves 5-lobed, with palmate 



nerves ,6. Ivy L. 



Plant hairy. Leaves ovate or angular, with pinnate 

 nerves. 

 Leaves ovate or orbicular, very hairy. Peduncles 



hairy. Sepals broad 7. Round-leaved L. 



Leaves angular or hastate at the base, slightly hairy. 



Peduncles glabrous and slender. Sepals narrow . 8. Pointed L. 



L. purpurea, a tall Italian species, with narrow leaves, and a long 

 raceme of small purple flowers, has become almost naturalized in the 

 south of the Isle of Wight, and several other species, such as i. tri- 

 phylla and bipartita, cultivated in our flower-gardens, will occasionally 

 sow themselves in the vicinity, but soon disappear again. 



3 . Common Linaria. Linaria vulgaris, Moench. (Fig. 727.) 



(Antirrhinum Linaria, Eng. Bot. t. 658. Toadflax.) 



Rootstock shortly creeping. Stems erect, 1 to 3 feet high, of a glau- 

 cous green, and usually glabrous, except a few glandular hairs amongst 

 the flowers. Leaves crowded, linear or narrow-lanceolate. Flowers 

 large and yellow, forming a short but handsome terminal panicle. 

 Calyx small. Spur of the corolla long and pointed ; the projecting 

 palate of the lower lip of a bright orange-colour, completely closing
