Lindernia dubia 

 var. major (Pursht Pennell 



1. Lindernia dubia (L.) Pennell var. typica Pennell. (Ilysanthes dubia 

 (L.) Barnh.) Map 1836. Probably infrequent to frequent throughout the 

 state. It grows in moist or muddy bare places about ponds, on bars and on 

 the banks of streams and ditches, and in logging roads in woodland. 



W. Vt. to e. N. Dak., southw. to Fla. and e. Tex. 



la. Lindernia dubia var. major (Pursh) Pennell. Map 1837. This form 

 is probably nearly as common as the preceding one and as well distributed. 

 The two forms of this species are not well marked and it is sometimes diffi- 

 cult to say to which form a specimen belongs. The habitats are the same as 

 those of the preceding variety. 



N. S. to Minn., southw. to Fla. and La. 



2. Lindernia anagallidea (Michx.) Pennell. (Ilysanthes anagullidea 

 (Michx.) Rob.) Map 1838. This species is infrequent and all of my speci- 

 mens are from the western and southern parts of the state. The habitats 

 are the same as those of the preceding varieties, but it prefers a more sandy 

 soil.

7579. VERONICA [Bauhin] L. Speedwell 

 Leaves of the stem and of the branches below the flowers opposite, those subtending 

 the flowers alternate (rarely a few flowers in the axils of opposite leaves in 

 Veronica persica) ; flowers solitary in the axils of the upper leaves. 

 Styles hidden between the lobes of the capsules, appearing obsolete, less than 0.5 

 mm long. 



Stems glabrous; capsules glabrous 1. V. peregrina var. typica. 



Stems glandular-pubescent; capsules of Indiana specimens glabrous, those west 



of our area more or less pubescent la. V. peregrina var. xalapensis. 



Styles mostly 0.5-2 mm long. 



Pubescence of the stem curved upward, the hairs short, mostly 0.2-0.4 mm long 

 and not conspicuously multicellular; perennial from a subterranean rhizome. . . 



2. V. serpyllifolia. 



Pubescence of stem spreading or partly upwardly curved, the spreading hairs not 

 more than 0.5 mm long and conspicuously multicellular; the curved hairs, if 

 any, like those of the preceding species; annual.
