1921] Pennell, — "Veronica" in North and South America 35 



Veronica crenatifolia Greene, 1. c. 1 14. 1903. "The type . . . 

 is Baker, Earle and Tracy's n. 33, from along the Mancos River 

 in southern Colorado, 22 June, 1898." Isotypes seen in Herb. New 

 York Botanical Garden and U. S. National Herbarium. Apparently 

 supposed to be distinguished by its smaller size and crenate leaves, 

 variations frequent in V . americana. 



Swamps, springs and woodland rills, from Newfoundland, Ontario 

 and Alaska, south, eastward to South Carolina and Tennessee, west- 

 ward to Chihuahua, California, and the Valley of Mexico; also on the 

 Commander Islands on the western side of Bering Sea. Generally 

 common over this wide area. 



Veronica americana appears to be only inconstantly distinguish- 

 able from V. Beccabunga by its leaf-form and more erect habit. The 

 leaf is mostly narrower, widest near the truncately rounded or sub- 

 cordate base, narrowing to the acute or obtuse apex, and borne on 

 frequently shorter pedicels. The capsule-shape is the same, nearly 

 globose, flattened and emarginate at apex, the corolla, sepals and 

 pedicels are of about the same length as in that species, but the last 

 are usually more slender. The styles are longer and usually more 

 slender in americana. The leaves vary from serrate through crenate 

 to nearly or quite entire. 



25. Veronica Anagallis-aquatica L. 



Veronica Anagallis-aquatica L., Sp. PI. 12. 1753. "Habitat in 

 Europa ad fossas." Description quoted from Linne, PI. Suec. 5, 

 no. 10. 1745, where the plant is stated to occur in Sweden "in fossis 

 ad vias & paludes Uplandiae, Scaniae &c. " Described with leaves 

 serrate, and with citations to Tournefort and Bauhin who both term 

 the leaves oblong. The Swedish plant is well described by Nyman, 

 Utkast Sv. Vaxt. Naturh. Sver. Fanerog. 164. 1867, who tells us 

 that its leaves are lanceolate or oval-lanceolate, pointed, and its 

 capsules are rounded, very shallowly notched. All which indicates 

 the present broad-leaved plant with scarcely or not notched capsules, 

 not another plant of northwestern Europe which has elongate acumi- 

 nate leaves, and capsules decidedly notched, as broad as or broader than 

 long. Our plant has the lower leaves and those of autumnal shoots 

 narrowed or petioled at the base, a condition mentioned in such exact 

 descriptions as Hayek, Fl. Steiermark 2: 168. 1912; also the short 

 round form of these autumnal leaves is mentioned in Villars, Hist. 

 PI. Dauphine 2: 14. 1787. 



Veronica lepida Phil, in Anal. Univ. Chile 91 : 110. 1895. " Habi- 

 tat ad Vicum Cartajena (haud procul a Valparaiso [Chile]), Februario, 

 1895 lecta. " Described because the petioled lower leaves were 

 noticed.
