In deep moist woods. Northern part of the State of New York ! and New 

 England States! to the shores of the Arctic Sea, and from Hudson's Bay to 

 the Rocky Mountains ! June. — Caudex slender, sending out, after flowering, 

 long filiform leafy stolons. Leaves thin and membranaceous, hirsute with 

 scattered hairs above ; the lobes or crenatures rounded. Scapes 4-6 inches 

 high, 5-10-flowered. Flowers greenish. The Siberian specimens of M. nuda 

 in the herbarium of Linnfeus, as well as those of Pallas in the herbaria of 

 Lambert and Willdenow, are the same with the N. American plant. 



§ 2. Stamens 5, alternate ivith the (pinnatijid) iie.tals: Jilaments rather short : 

 calyx adherent to the base of the ovary : stigmas simple : placenta; parietal, 

 many-ovuled : scape 2-3-leaved. — Mitellastra. 



3. M. caulescens (Nutt. ! mss.) : " leaves roundish-cordate, 3-5-lobed, 

 obtuse, crenate ; the cauline ones 2-3, alternate, petioled ; raceme many- 

 flowered ; calyx flat ; petals filiformly pectinate-piunatifid ; stamens 5." 



Shady woods of the Oregon, near the mouth of the Wahlamet, Nuttall! 

 — Plant 10-12 inches high. Leaves sparingly hirsute on both sides, ob- 

 tusely and rather deeply lobed, the crenatures obtuse and mucronate, 

 sparingly hirsute on both sides, as large as in M. diphylla. Flowers yel- 

 lowish-green, larger than in M. nuda : pedicels longer than the flowers. 

 Styles slender. — Wholly accords with the decandrous species, except in the 

 number of the stamens and the many-ovuled placentas, which reach nearly 

 to the summit of the capsule, as in the following sections. 



§ 3. Stamens 5, opposite the {pinnatijid) petals : Jilaments very shm-t : calyx 

 adherent nearly to the summit of the ovary : stigmas subsessile, 2-lobed : 

 capsule opening long before the ripening of the seeds : placenta parietal, 

 many-ovuled: scape naked. — Mitellaria. (Drummondia, DC. not of 

 Hook. — Mitellopsis § Mitellaria, Meisn. ; Endl.) 



4. M. pentandra (Hook.) : leaves all radical, cordate, slightly lobed,
