JENNINGS: PLANTS FROM NORTHWESTERN ONTARIO 459 



a few spreading hairs on the veins beneath, thin, shallowly crenate- 

 serrate, bluntly acute, rounded or truncate below into a flattened 

 petiole 1-2 mm. long; leaves on shoots arising from the decumbent or 

 lower part of stem often larger, very thin, sometimes oblanceolate, 

 and more gradually narrowed at the base into a longer (1-4 mm.) 

 and more slender petiole; inflorescence consisting of 5- 11 whorls, about 

 1-1.3 dm. long, lax, the lowest whorls situated in the axils of the upper 

 leaves; calyx more or less black-dotted, campanulate, 7-9 mm. long, 

 sparsely glandular-puberulent and sparsely longer-hispid on the nerves 

 and teeth, the teeth moderately spreading and with somewhat spinose 

 tips; corolla widely gaping, the tube often a little shorter than the 

 calyx teeth, puberulent on upper side, slightly so below, about 13-15 

 mm. long, the rounded terminal lobe of the lower lip at least twice 

 longer and twice wider than the lateral lobes. 



Collected in two places in a black-ash swamp at the east end of 

 Pelican Lake, Sioux Lookout, Ontario, O. E. & G. K. Jennings, Aug. 

 18, 1914, Nos. 11,031 (type) and 11,015. Carnegie Museum Herbarium. 



In four of the five specimens collected, the short erect portion of the 

 stem arose from a somewhat swollen prostrate stem from 3-5 dm. long 

 rooted only at the lower end but presenting the appearance of having 

 wintered under water, and sending up during the following season the 

 terminal flowering shoot and also the axillary larger-leaved shoots from 

 along the stem itself. 



Stachys palustris var. nipigonensis Jennings, var. nov. 



Ashy green in color, with a whitish pubescence; but lower part of 

 stem, axis of inflorescence, and the calices usually more or less purple; 

 stem 3-7 dm. high, simple or rarely branched above, rather slender, 

 covered especially above with a more or less glandular whitish puber- 

 ulence mixed on the angles of the stem with slender but stiff, jointed, 

 spreading hairs; basal leaves small, linear-oblong to oblong-oval, the 

 median leaves 4-7 cm. long by 0.8-2 cm. wide, narrowly oblong to oval- 

 oblong or oblong-obovate, abruptly rounded to a subcordate base with 

 a short (1-3 mm.) petiole, strongly margined and often with one or two 

 pairs of lateral veins, running independently down to the stem; leaves 

 thin, shallowly crenate-serrate, finely appressed-hispidulous above, 

 below with spreading hairs on the veins, the apex of the lower leaves 

 obtuse, the middle and upper leaves bluntly acute; inflorescence some- 

 times short, but usually later elongated occasionally reaching a length 

 of 14 cm., widely interrupted below, denser and spicate above, the lowest 

 whorls often in the axils of the comparatively large uppermost leaves; 

 the floral bracts mainly about the same length as the calyx, lanceolate 

 and often reflexed; calyx practically sessile, about 7 mm. long, narrowly 

 campanulate, more or less glandular-puberulent and with stiffer hairs 

 on the nerves and teeth; teeth spreading, two-thirds to three-fourths 

 the length of the tube, narrowly triangular, moderately spinous-tipped ; 

 corolla 12-15 rn^- ^ong, more or less puberulent and glandular-puberu- 

 lent on the upper side and somewhat so beneath, widely gaping, the lower 

 lip spotted, the lateral lobes about one-third as wide and one-third|as 

 long as the middle, rounded lobe.
