SCEOPHUIAEISE.?;. 393 



The species are not numerous, chiefly confined to the Mediterranean re- 

 gions, or more especially to south-western Europe. 



Perennial, vrith showy flowers. Sepals broad and short ...... 1. Great S. 



Aimual. Sepals narrow, as long as the corolla 2. Lesser S. 



1. Great Snapdragon. Antirrhinuni majus, Linn. 

 (Eng. Bot. t. 129.) 



Stem perennial at the base, forming a leafy tuft ; the flowering branches 

 erect, 1 to 2 feet high, glabrous or slightly downy, often brauclied. Leaves 

 narrow-lanceolate or hnear, entire. Flowers large, purplish-red (or, in gar- 

 dens, white or variegated). Segments of the calyx broad and obtuse, not 

 above 3 hues long. CoroUa above an inch long, the so-called palate opening 

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

 the popular name of the genus. 



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

 gion, but, being much cultivated in gardens, it has become naturalized 

 much further north, and is fi-equentlj' found in similar situations in southern 

 England and Ireland. Fl. summer and autumn. 



2. Iiesser Snapdragon. Antirrhinum Oroutium, Linn. 

 (Eng. Bot. t. 1155.) 



An erect annual, seldom above a foot high, much more slender tl:an the 

 great S., 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 southern and eastern 

 England and southern Ireland. Fl. summer. 



III. I.INARIA. LINARIA. 



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

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

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

 stUl the greater nvunber 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, diifuse 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 terminal 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, mth pinnate nerves. 



Leaves ovate or orbicular, very hairy. Peduncles hairy. Sepals
