1921] Pennell, — "Veronica" in North and South America 37 



While in pubescence this species parallels Palaearctic derivatives 

 of Veronica Anagallis-aquatica L., I am unable to place our plant of 

 eastern North America as of the same species as any of these. Such 

 species are: V. anagalloides Guss., PI. Rar. Sic. 5. pi. 3. 1829, which 

 has a capsule decidedly longer than wide, and not or scarcely emargi- 

 nate; V. oxycarpa Boiss., Diagn. I. 7: 44. 1846, with acute capsule 

 and leaves narrowed at base; and V. salina Schur, Enum. PI. Trans- 

 silv. 492. 1866, very similar to V. anagalloides. 



27. Veronica catenata Pennell, sp. nov. 



Flowering stem 1-3 dm. long, glabrous throughout. Leaves 

 lanceolate, acute or acutish, crenate to nearly entire, 3-5 cm. long, 

 1 cm. wide, all clasping, when submersed elongating and reaching 

 12 cm. long and 2 cm. wide. Racemes axillary to the upper leaves, 

 6-12 cm. long, 15-25-flowered. Bracts narrowly lanceolate, 4-5 mm. 

 long. Pedicels 3-5 mm. long, glabrous. Sepals 3-3.5 mm. long, 

 lance-ovate, obtusish. Corolla-lobes pale-blue. Style 1.2-1.7 mm. 

 long. Capsule 3 mm. long, 3.5 mm. wide, broad-globose, decidedly 

 emarginate. Seeds 0.5 mm. long, yellow-brown. 



Type, Hot Springs, South Dakota, collected in flower and fruit 

 June 16, 1892, P. A. Rydberg 926, in Herb. New York Botanical 

 Garden. Named from the chain-like aspect of the long racemes of 

 short-pedicelled flowers. 



Slow-flowing, streams, plains, from North Dakota and Saskatch- 

 ewan to Kansas and New Mexico, southward west to Nevada and 

 southern California. 

 27a. Veronica catenata glandulosa (Farwell) Pennell, comb. nov. 



Veronica Anagallis-aquatica glandulosa Farwell in Rep. Mich. 

 Acad. Sci. 19: 249. 1917. "Zoo Park, near Royal Oak [Michigan], 

 [Farwell] No. 4323, July 13, 1916." Not V. Anagallis-aquatica 

 glandulosa Schur, Enum. PI. Transsilv. 492. 1866. Description 

 inadequate, but apparently of the plant now considered. As this 

 is a small plant and moreover is the only glandular-pubescent " Ana- 

 gallis-aquatica" known from Michigan, I apply the name to this. 



Slow-flowing streams, western New York to Minnesota, South 

 Dakota, Kentucky and Oklahoma; also in western Massachusetts 

 and in southeastern and southern Pennsylvania. Probably inter- 

 grades with V. glandifera, and for the latter, in Torreya 19: 170, 

 [ have mistaken plants of our New York " Local Flora. " 



28. Veronica undtjlata Wall. 



Veronica undulata Wall.; Roxb., Fl. Ind. 1: 147. 1820. "Dis- 

 covered in the Turraye [India] by Mr. W. Jack. " Specimen in Herb. 

 Columbia University, labeled "Nepal Wallich," may be an isotype.
