io8 The Ottawa Naturalist. [August 



anthers of equal length ; flowers protandrous, the ovary sunk in 

 the disc ; style rather slender, at first short, later elongated, 

 stigma slightly bilobed. Fruit scanty. 



Pachystima Schaefferi, sp. nov. 



Twigs spreading as in P. macrophyllum, but the color and 

 ridges approaching P. Myrsinites, the internodes very variable, 

 from 2-10 mm. long, the leaves in one plane, shortly petiolate, the 

 petioles slightly swollen, the bladdery swelling often prolonged 

 into the midrib, lamina lanceolate to linear - lanceolate, the 

 veins evident, in 6-7 pairs, intermediate in position between P. 

 Myrsinites and P. macrophyllum, the margin blunt-toothed from 

 the middle upwards, slightly thickened, not revolute, bright green 

 above and below, translucent. 



Flowers agreeably odorous, very numerous, in short clusters 

 of 2-5, on slightly elongated branches ; sepals and petals as in P. 

 macrophyllum ; stamens 4, inserted into a quadrate disc ; filaments 

 one and one-half to two times longer than anthers ; style rather 

 thin, stigma strongly bilobed. 



Pachystima Krautteri, sp. nov. 



Twigs elongate, closely spreading in one plane, grayish- 

 brown, the internodes 9-1 1 mm. long, the leaves rather crowded, 

 closely ascending in one plane, shortly petiolate, the petioles grad- 

 ually attenuate into the midrib, lamina elliptic to elliptic-lanceolate, 

 the veins evident below, obscure above, in 4-5 pairs, obliquely 

 radiating, the margins strongly and sharply dentate in the upper 

 half, thickened and revolute, bright yellowish-green, rather thick, 

 almost opaque. 



Flowers few x in clusters of 1-3, on short branches, sepals 

 ovate-deltoid, midrib not discernible, the margins entire, or near- 

 ly so, petals not seen, stamens 4, disc as in P. macrophyllum, 

 style rather slender, with slightly enlarged, faintly bilobed stigma. 

 Fruit not seen. 



The following new species were also collected during the sum- 

 mer of 1905. The type specimens of these, as well as of those of 

 Pachystima Schaefferi and P. Krautteri are in the Herbarium of 

 the University of Pennsylvania. ^t\^\CA/
