 from gardens. Introduced from Mexico. 



24. LINARIA Miller. 

 Linaria Mill., Gard. Diet. ed. IV. 1754. 

 Type species, Antirrhinum linaria L., of Europe. 



Corolla, excluding spur, 4-12 mm. long, blue, posterior lip erect; 

 anterior lip broadly spreading, but not forming a definite raised 

 palate. Capsule 2-3.5 mm. long, equaling to exceeding the 

 sepals. Seeds .3-.4 mm. long, cylindric, prismatic-angled, not 

 winged. Stem less leafy, the younger stems spreading-prostrate 

 from base. (Leptoplectron.) 



Pedicels glandular-pubescent, longer than the corollas. Spur very 



short. 1. L. fioridana. 



Pedicels nearly glabrous, shorter than the corollas. Spur slender. 

 Corolla less than 8 mm. long, excluding the spur. Surface 

 of seeds smooth to slightly tuberculate. 2. L. canadensis. 

 Corolla over 10 mm. long, excluding the spur. Surfaces and 

 angles of seed densely tuberculate. 3. L. texana. 



Corolla, excluding spur, 15-18 mm. long, yellow; posterior lip arched 

 over anterior; anterior lip forming a conspicuous protruding 

 orange palate; spur stout. Capsule 10 mm. long, much ex- 

 ceeding the sepals. Seeds 1.7 mm. long, flattened and cir- 

 cularly broadly winged. Stem densely leafy, always erect.

2. Linaria canadensis (L.) Dum.-Cours. 



Antirrhinum canadense L., Sp. PI. 618. 1753. "Habitat in Virginia, 

 Canada." Type probably from southern New Jersey, and certainly the

Linaria canadensis Dum.-Cours. Bot. Cult. 2: 96. 1802. "Lieu, Le Can- 

 ada, la Virginie." Doubtless based upon Antirrhinum canadense L. 



Open sandy soil, usually a weed, mostly common in the At- 

 lantic Coastal Plain south to central Florida (intergrading somewhat 

 with L. texana in Georgia and Florida) ; in the Piedmont on the
