Antirrhinum.] LVL SCROPHULARTNE^ 527 



1. A. majus, Linn. (fig. 732). Great S. Stem perennial at the base, 

 forming a leafy tuft ; the flowering branches erect, 1 to 2 feet high, 

 glabrous or slightly downy, often branched. Leaves narrow-lanceolate 

 or linear, entire. Flowers large, purplish-red (or, in gardens, white or 

 variegated). Segments of the calyx broad and obtuse, not above 3 lines 

 long. Corolla above an inch long, the so-called palate opening when 

 the tube is pressed laterally between the finger and thumb, whence the 

 popular name. 



In clefts of rocks, old walls, and stony places, in the Mediterranean 

 region, but being much cultivated in gardens, it has become naturalised 

 much farther north, and is frequently fcund on old walls in England 

 and Ireland. PL summer and autumn. 



2. A. Orontium, Linn. (fig. 733). Lesser S.An erect annual, seldom 

 above a foot high, much more slender than A. majus, with narrower 

 leaves. Flowers scarcely 6 lines long, mostly in the axils of the upper 

 leaves ; the narrow, unequal segments of the calyx as long as or longer 

 than the corolla. 



Apparently indigenous in southern Europe, and widely spread as a 

 weed of cultivation over the greater part of Europe and central Asia, 

 and carried out to other countries. In Britain, it extends over England 

 and southern Ireland. Fl. summer. 



III. LINARIA. LINARIA. 



This genus only differs from Antirrhinum 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. 

 Steins erect or ascending. Leaves linear, oblong or rarely 



ovate, entire. 

 Flowers yellow. 



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

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

 Flowers blue or purplish or striped. 

 Perennial. Flowers on short pedicels, In terminal racemes. 



Spur short and conical 2. L. repent. 



Annual. Flowers on short pedicels, in a short terminal 



raceme. Spur long and slender 3. L. Pelituriana. 



Annual. Flowers small, on long axillary pedicels. Spur 



short and conical 6. L. minor. 



Btems trailing. Leaves ovate, orbicular, or angular. 



riant quite glabrous. Leaves 5-lobed, with palmate nerves . 6. L. Cymbaiaria. 

 Plant hairy. Leaves ovate or angular, with pinnate nerves. 

 Leaves ovate or orbicular, very hairy. Peduncles hairy. 



Sepals broad 7. L. tpuria. 



Leaves angular or hastate at the base, slightly hairy. Pe- 

 duncles glabrous and slender. Sepals narrow . . 8. L. Elatine. 

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

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

 south of the Isle of Wight, and several other species, such as L. triphylla 

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

 themselves in the vicinity, but soon disappear. 



1. L. vulgaris, Mill. (fig. 734). Toadflax. Rootstock shortly creep- 

 ing. Stems erect, 1 to 3 feet high, of a glaucous green, and usually
