454 JENNINGS: PLANTS FROM NORTHWESTERN ONTARIO 



Kneiffia depauperata Jennings, sp. nov. 



Stems wiry, flexuous, decumbent to ascending or almost erect, 1-1.5 

 dm. long, moderately appressed- pubescent with fine white hairs, 

 brown, sublustrous, rarely with a few branches; leaves finely appressed- 

 puberulent; rosette leaves 2-3 cm. long, 6-9 mm. wide, spatulate- 

 oblong, rounded at apex, gradually narrowed to a margined petiole; 

 stem leaves mostly bunched in about the middle third of the stem, 

 linear-oblong, about 1.5-2.4 cm. long, 4-6 mm. wide, entire or slightly 

 undulate, rounded to bluntly acute, tapering below into a short mar- 

 gined petiole, light green above, paler below, often strongly tinged with 

 rose-purple ; upper part of stem with few or no leaves below the flowers ; 

 flowers 1-4 on stem and 1-2 on branches, the floral bracts, if present, 

 similar to leaves, but smaller, usually shorter than the capsule; capsule 

 5-6 mm. long, oblong-club-shaped, winged on the angles, sparsely 

 glandular-puberulent, tapering below into a pedicel 4-8 mm. long; 

 seeds brown, dull, narrowly ovoid, about i mm. long, minutely pitted. 



Type growing in matted brownish and partially decayed leaf- 

 remains along the shore of a boulder-strewn bay of the lake northeast of 

 Sioux Lookout, northwestern Ontario, O. E. & G. K. Jennings, Sept. 

 7, 1914, No. 7,501. Carnegie Museum Herbarium. 



This species resembles a weak sprawling specimen of Kneiffia pumila, 

 but the leaves are rather strongly appressed-pubescent with fine rather 

 stiff hairs, and the capsules are usually exceeded in length by their 

 pedicels. From A', linearis it differs in having the capsules glandular- 

 puberulent and the pedicels longer, the plant having the pubescence 

 distinctly appressed on stem and leaves. K. depauperata is perhaps 

 most nearly related to the decumbent plant of the sands of eastern 

 Long Island, A.'. Alleni (Britton) Small, {Oenothera fruticosa var. 

 humijusa Allen), but the minute pitting on the seeds of the Ontario 

 plant appears not to be in distinct rows, and in shape of capsule also 

 there appears to be a difference. 



Pjrrola uliginosa var. gracilis Jennings, var. nov. 



Differing from the typical Pyrola uliginosa Torrey in its more 

 slender form, the pedicels longer than the bracts, the veinlets towards 

 the margins of the leaves excurrent into the crenulate teeth. 



The leaf blades are about 2.5-3.5 ^m. long by 2.1-2.4 cm. wide, 

 varying from emarginate to slightly acute at the apex, rather stiffly 

 membraneous, sub-lustrous to dull, marginally crenulate, at the base 

 gradually tapering into margined petioles which are slender and 3-5 

 cm. long; scape 2.5-3 cm. high, bearing 5-8 scattered flowers on slender 

 pedicels about 8 mm. long, in the axils of lanceolate acuminate bracts 

 about 5 mm. long; calyx -lobes acute, ovate-lanceolate, about 2.5 mm. 

 long by 1.5 mm. wide just above the base; petals obovate-oblong, ob- 

 tuse, about 7-8 mm. long, spreading rather widely; anthers about 2.5 

 mm. long, distally mucronate, the pores terminating short curved tubes,
